SoMa’s Trusted Roofing Contractor

South of Market is unlike any other roofing market in San Francisco. If you own property here — a converted 1920s warehouse loft near 2nd and Bryant, a high-rise condo tower on Folsom Street, a tech office near the Caltrain corridor, a mixed-use building on Howard Street, or a light-industrial property near the Bay Bridge on-ramps — you already know SoMa doesn’t roof like the Sunset, the Richmond, or the Mission. Built largely on reclaimed bay fill and 1906 earthquake debris, the district combines soft, liquefaction-prone soil, a mixed building stock ranging from century-old brick-and-timber warehouses to brand-new towers, chronic low-elevation stormwater challenges, and dense rooftop equipment loads from tech offices, restaurants, and multi-tenant commercial buildings.

That combination drives everything about how a roof needs to be built here. SoMa’s roofing stock is overwhelmingly flat and low-slope, carrying heavy point loads from HVAC units, solar arrays, and amenity-driven rooftop decks — on buildings that move differently in a seismic event and drain into a stormwater system known for backing up fast during flash-flooding events. We are CSLB-licensed roofing contractors serving ZIP codes 94103, 94105, and 94107 with crews who understand SoMa’s structural, drainage, and DBI permit realities — including the additional structural review that older industrial conversions frequently require. Here is everything you need to know about every roofing service we provide in SoMa.

The Problems SoMa Property Owners Are Actually Facing

Before we break down individual services, you need to understand why SoMa roofing is a categorically different discipline from roofing anywhere else in San Francisco. This isn’t positioning — it’s structural reality driven by the district’s soil, building stock, and density.

The Fill Soil & Seismic Movement Problem

Much of SoMa sits on filled land — a combination of Gold Rush-era bay fill and debris deposited after the 1906 earthquake and fire. This soil profile behaves very differently than the bedrock and dune sand under most of San Francisco’s western neighborhoods:

  • Buildings on fill soil experience measurably more differential settlement over time, which telegraphs directly into roof deck deflection, parapet cracking, and membrane stress fractures at movement joints
  • Older unreinforced masonry (URM) warehouse conversions common near 2nd, 3rd, and Folsom Streets require roof-level seismic retrofit coordination — expansion joints, parapet bracing, and flashing details engineered to move with the building rather than tear
  • New high-rise and mid-rise construction on deep pile foundations moves differently than adjacent older buildings, which matters directly for rooftop equipment curbs, walkway pad placement, and membrane termination details at structural expansion joints
  • Roof-mounted mechanical equipment anchoring must account for seismic bracing requirements that standard inland installations do not

The Chronic Stormwater & Low-Elevation Flooding Problem

SoMa is one of San Francisco’s lowest-elevation districts and sits on a section of the city’s combined sewer system that is well known for surcharging during heavy rain events. This creates specific roofing consequences that most contractors outside the district have never had to engineer around:

  • Internal roof drains and scuppers on SoMa flat roofs must be sized and maintained aggressively — during peak storm events, the municipal system backs up faster here than in higher-elevation neighborhoods, meaning a roof’s own drainage capacity becomes the primary defense against interior flooding
  • Secondary (overflow) drainage systems are not optional in SoMa — they are a practical necessity given documented flooding history near Folsom, Howard, and the low-lying blocks toward the Caltrain corridor
  • Ponding water on older built-up roofs accelerates membrane fatigue and adds dead load that older warehouse roof structures were not always designed to carry
  • Green roof and stormwater-retention roof systems, increasingly required or incentivized on new SoMa development, require specialized drainage engineering most residential roofers have never installed

The Converted Warehouse & Industrial Building Problem

SoMa’s early-1900s brick-and-timber warehouses — many now converted to live-work lofts, tech offices, and creative office space — carry roofing challenges that don’t exist in the city’s residential neighborhoods:

  • Original monitor skylights and clerestory windows built into industrial roof structures require specialized flashing and waterproofing details that standard skylight replacement crews are not trained to handle
  • Heavy timber roof decking, often a century old, requires careful structural assessment before any new membrane load is added
  • Adaptive-reuse buildings frequently carry mixed roof ages and materials across a single roof plane — additions, patches, and prior owner repairs stacked over decades — requiring a full roof-history assessment before scoping any repair or replacement
  • Fire-rated assembly requirements are more stringent on converted live-work and mixed-use occupancies, and DBI reviews these buildings under different code pathways than standard residential construction

The Rooftop Equipment & Amenity Deck Load Problem

SoMa’s density means rooftops do far more work here than in most San Francisco neighborhoods:

  • Tech offices and commercial buildings load roofs with HVAC package units, server room cooling equipment, cell carrier equipment, and solar arrays — often stacked and added to over years without a coordinated load plan
  • Restaurant and food service tenants in mixed-use SoMa buildings require dedicated grease-resistant membrane specification at kitchen exhaust penetrations
  • Rooftop decks, gardens, and outdoor amenity spaces — a defining feature of SoMa’s condo and apartment towers — require pedestrian-traffic-rated waterproofing systems engineered for heavy foot traffic, furniture point loads, and planter drainage
  • Solar installations are far more viable in SoMa than in San Francisco’s fog-heavy western neighborhoods, and rooftops here are increasingly asked to support PV arrays on top of existing HVAC and amenity infrastructure

The DBI Permit & Occupancy Complexity in 94103, 94105 & 94107

SoMa spans three ZIP codes with distinct building-stock character: 94103 (western SoMa, including the Central Freeway corridor and Civic Center-adjacent blocks), 94107 (the warehouse and loft district toward Potrero and the ballpark), and 94105 (the Financial District-adjacent high-rise blocks near the Embarcadero and Bay Bridge). Every full roof replacement or structural roof repair requires a DBI permit, and converted industrial buildings frequently require additional structural or occupancy review given their adaptive-reuse history. Getting the permit pathway right — particularly on mixed-occupancy buildings with live-work, commercial, and retail tenants under one roof — is a detail that directly affects project timelines.

How We Solve It

We engineer every SoMa roofing project around the building’s actual structural and drainage reality — not a generic flat-roof template. For converted warehouses, that means a full structural assessment of original timber decking before any new membrane load is added. For high-rises and mid-rises on deep foundations, that means detailing every penetration and termination to accommodate building movement at expansion joints. For every SoMa roof, that means drainage capacity sized for the district’s documented flooding history — primary and secondary overflow systems, not primary drains alone.

We coordinate directly with structural engineers on seismic retrofit projects, size rooftop equipment curbs and anchoring to current seismic bracing code, and specify grease-resistant PVC membrane wherever a kitchen exhaust penetrates a SoMa roof. We manage the full DBI permit lifecycle — including the additional structural and occupancy review that adaptive-reuse buildings often require — from application through final inspection sign-off.

Our Process

  1. Full roof and structural assessment — physical access to every roof section, roof-history review on older buildings, and identification of prior patch layers, deck condition, and drainage capacity
  2. Engineering coordination where required — structural engineer sign-off on seismic bracing, expansion joint detailing, and added rooftop equipment loads on older buildings
  3. Written, fixed-price, line-item scope — including protocol for handling deteriorated decking, undersized drainage, or non-code equipment curbs discovered during tear-off
  4. DBI permit management — including structural and occupancy review pathways specific to converted and mixed-use SoMa buildings
  5. Tear-off and structural verification of decking, roof framing, and equipment anchoring
  6. Installation to current code — seismic-rated equipment curbs, primary and secondary drainage, and fire-rated assemblies matched to occupancy type
  7. Final DBI inspection sign-off and documentation for ownership, insurance, and future capital planning records

Materials We Specify on Every SoMa Project

  • Seismic-rated rooftop equipment curbs and anchoring hardware
  • Primary and secondary (overflow) drainage systems sized for SoMa’s documented flooding history
  • PVC single-ply membrane at all kitchen exhaust and grease-exposure penetrations
  • Heavy-duty pedestrian-traffic-rated waterproofing for rooftop decks and amenity spaces
  • Fire-rated assemblies matched to mixed-occupancy and live-work code requirements
  • Tapered insulation systems engineered to correct settlement-driven deck deflection on older buildings
  • Reflective TPO and cool-roof membrane systems for Title 24 compliance on new construction and re-roofs

Roof Repair in SoMa, SF | 94103, 94105 & 94107 | Same-Day Leak Diagnosis & Emergency Fix

“Water is coming through the ceiling near the old skylight,” “our server room had water intrusion at the roof penetration,” and “the roof deck drain backed up and flooded the top-floor unit” are among the most frequent calls we get from 94107 and 94103 building owners and property managers after a significant storm.

In SoMa’s mixed building stock, that leak could originate from a failed monitor skylight seal on a converted warehouse, a settlement-cracked parapet on an older brick building, an undersized roof drain overwhelmed during a flash storm, or a poorly flashed HVAC curb added by a previous tenant without proper waterproofing integration.

What separates a real repair from a temporary patch in SoMa: We trace water to its actual origin point using systematic water testing, moisture scanning, and — on older converted buildings — a review of the roof’s repair history, since multiple patch layers from different eras frequently mask the real failure point. On buildings with original timber decking, we also assess whether water intrusion has caused structural deterioration before making any repair recommendation.

Common SoMa roof repairs we handle:

  • Monitor skylight and clerestory window reflashing on converted warehouse and loft buildings
  • Parapet crack repair and re-waterproofing on settlement-affected older masonry buildings
  • Roof drain and scupper capacity upgrades, including secondary overflow drain installation
  • HVAC curb reflashing and equipment penetration correction on commercial and tech office buildings
  • Membrane patching and seam repair on built-up, modified bitumen, and single-ply roofs
  • Rooftop deck waterproofing repair at planter boxes, furniture anchor points, and drain penetrations
  • Emergency storm leak response and interior water damage mitigation during flash-flood events
  • Grease-contaminated membrane replacement at restaurant and food service kitchen exhaust penetrations

What SoMa property owners should know before calling anyone for a repair: Demand a photo-documented estimate from an estimator who physically walks the roof and reviews the building’s roofing history — not one who quotes from a rooftop equipment inventory or a single photo. On older SoMa buildings with decades of patch-on-patch repairs, an accurate diagnosis requires understanding what’s actually underneath the visible surface.

Roof Replacement in SoMa, SF| 94103, 94105 & 94107 | DBI-Permitted & Structurally Engineered

Full roof replacement in SoMa is rarely a straightforward tear-off-and-recover job. The combination of fill-soil settlement effects, aging timber decking on converted buildings, heavy accumulated rooftop equipment loads, and stormwater drainage capacity requirements makes SoMa replacement work fundamentally different from a standard residential re-roof elsewhere in the city.

When replacement is the right answer instead of repair:

  • Membrane age and condition showing systemic failure — widespread alligatoring, multiple active seam failures, or repeated leaks across different roof zones each storm season
  • Structural decking found compromised during inspection — common on older timber-framed warehouse conversions with a history of undetected moisture intrusion
  • Rooftop equipment load has exceeded what the original roof structure and drainage system were designed to handle, requiring a full reassessment as part of replacement
  • Drainage capacity is documented as inadequate for current storm intensity, requiring redesign as part of the replacement scope
  • Insurance carrier or capital planning requirements citing roof age, condition, or documented flooding history
  • Seismic retrofit work elsewhere in the building creates an opportunity to correct roof-level bracing and termination details at the same time

Our SoMa replacement process: We pull all permits directly through San Francisco DBI, including additional structural or occupancy review where required on converted and mixed-use buildings. Every tear-off includes a complete structural inspection of exposed decking and framing — critical on SoMa’s older timber-framed buildings where decades of prior roofing work may have masked deterioration. Where rooftop equipment is present, we reassess anchoring and curb condition against current seismic bracing code before reinstallation. Drainage capacity is recalculated against current code and the building’s documented flooding history, with secondary overflow systems added where the original design lacked them.

You receive a written, fixed-price, line-item scope before any work begins — including our explicit protocol for handling compromised decking, undersized drainage, or non-compliant equipment anchoring discovered during tear-off.

Commercial Roofing in SoMa, SF | 94103, 94105 & 94107 | Top-Rated for Tech Offices, High-Rises & Mixed-Use Buildings

SoMa is San Francisco’s most concentrated commercial and mixed-use roofing market — tech office campuses, converted creative office space, ground-floor retail beneath residential towers, and restaurant-anchored mixed-use buildings all carry flat commercial roofs with drainage, equipment, and occupancy demands that a residential-only crew is not equipped to handle.

Commercial roofing services we provide in SoMa:

  • Full commercial low-slope membrane replacement including TPO, PVC, modified bitumen, and built-up systems on office, retail, and mixed-use buildings
  • Rooftop HVAC and server cooling equipment curb fabrication and reflashing, engineered for tech office rooftop load density
  • Roof drain and scupper hydraulic redesign for buildings with documented ponding or flooding history
  • Structural deck assessment and tapered insulation correction on older commercial and industrial buildings
  • Commercial preventive maintenance programs with documented inspections — particularly important on buildings carrying heavy, frequently-modified rooftop equipment loads
  • Multi-tenant and HOA-managed high-rise re-roofing with tenant and property management coordination
  • Restaurant and food service roofing with PVC membrane specification at kitchen exhaust penetrations

For SoMa’s restaurant and food service tenants: Ground-floor restaurant and food hall tenants are common throughout SoMa’s mixed-use buildings, from Folsom Street to the blocks near Oracle Park. Cooking grease carried in kitchen exhaust air chemically degrades standard TPO membrane within three to five years. Above every commercial kitchen exhaust penetration in a SoMa building, we specify PVC single-ply membrane exclusively — a detail frequently missed by contractors without dedicated commercial and restaurant roofing experience.

Roof Installation in SoMa, SF | 94103, 94105 & 94107

New construction and adaptive-reuse projects throughout SoMa — from ground-up high-rise development to warehouse-to-loft conversions — require roof systems designed for the building’s specific structural profile from day one. Whether you’re finishing new construction near the Caltrain corridor, converting an industrial building to live-work or creative office space, or completing a mixed-use development along Howard or Harrison Street, our installation process accounts for seismic bracing requirements, drainage capacity sized to SoMa’s flooding history, and Title 24 cool-roof compliance built in from the start.

Flat Roofing in SoMa, SF| 94103, 94105 & 94107 | Best Modified Bitumen & Built-Up Systems for Converted Industrial Buildings

Flat and low-slope roofing dominates SoMa’s building stock — from century-old brick-and-timber warehouses to modern mid-rise residential and commercial buildings. The district’s converted industrial buildings in particular present flat roofing challenges that require careful structural and drainage assessment before any membrane work begins.

What proper flat roofing looks like in SoMa specifically:

  • Structural verification of original decking on converted warehouse buildings before any new membrane load is added
  • Tapered insulation systems correcting decades of settlement-driven deck deflection common on fill-soil buildings
  • Primary and secondary drainage fully assessed and upgraded where capacity is inadequate for SoMa’s documented storm intensity
  • Monitor skylight and clerestory integration detailing on adaptive-reuse buildings, where original industrial roof features must be waterproofed without compromising the building’s architectural character
  • Fire-rated assembly selection matched to the building’s actual occupancy classification — particularly important on mixed live-work and commercial buildings
  • Membrane selection matched to existing roof system where partial replacement or repair is the right scope, avoiding incompatible system transitions

The drainage reality for SoMa flat roofs: SoMa’s low elevation and documented history of storm-driven flooding make roof drainage capacity a life-safety and property-protection issue, not a maintenance afterthought. We assess every SoMa flat roof’s primary drainage capacity against current storm intensity data and install secondary overflow systems wherever the existing design lacks adequate backup — a detail that has prevented significant interior flooding losses on buildings we’ve serviced through major storm events.

TPO Roofing in SoMa, SF | 94103, 94105 & 94107 | Top Title 24 Cool Roof & High-Rise Specialists

TPO single-ply membrane is widely specified on SoMa’s newer commercial and residential construction for its combination of seam strength, thermal performance, and compatibility with heavy rooftop equipment loads. Heat-welded TPO seams create a durable, monolithic waterproof surface well suited to SoMa’s dense rooftop equipment environment.

Why TPO makes specific engineering sense in SoMa:

  • Title 24 Cool Roof Compliance: TPO’s white reflective surface meets California’s cool roof mandates and performs particularly well in SoMa’s warmer, less fog-affected microclimate compared to San Francisco’s western neighborhoods
  • Equipment Compatibility: TPO’s durability under foot traffic and equipment loading makes it well suited to SoMa roofs carrying dense HVAC, cell equipment, and server cooling infrastructure
  • Weight Advantage: TPO’s lighter weight compared to built-up gravel systems is a meaningful advantage on older converted buildings where structural capacity is already a consideration
  • Solar Compatibility: SoMa’s comparatively fog-free microclimate makes rooftop solar significantly more productive than in San Francisco’s western neighborhoods, and TPO’s reflective white surface is the preferred substrate for mechanically attached PV systems

Critical TPO specification detail for SoMa: On buildings with heavy or frequently modified rooftop equipment loads — common throughout SoMa’s tech office and commercial buildings — mechanical attachment must be engineered for current seismic bracing code, not just wind uplift. This is a detail we build into every SoMa TPO project involving equipment-dense rooftops.

Silicone Roof Coating in SoMa, SF | 94103, 94105 & 94107 | Best Flat Roof Restoration for Commercial & Industrial Buildings

Not every flat roof in SoMa requires a full tear-off. If the existing membrane is structurally sound — confirmed dry by moisture scanning and core sample analysis, with intact seams and no active delamination — a high-solids silicone roof coating restoration system can extend service life significantly at a fraction of replacement cost.

What silicone coating restoration involves in SoMa:

  • Electronic moisture scanning and core sample extraction to confirm the insulation substrate is completely dry — particularly important on older buildings with a history of undetected leaks
  • Mechanical cleaning and surface preparation, including removal of accumulated debris around rooftop equipment
  • Treatment of existing flashing and equipment curb terminations with compatible primers before coating application
  • Application of high-solids silicone base coat with reinforcement fabric at all seams, transitions, penetrations, and equipment curbs
  • Final reflective silicone topcoat application meeting Title 24 cool roof requirements

Who silicone coating is right for in SoMa: Commercial property owners and building managers who cannot absorb the tenant disruption and business interruption cost of a full tear-off, and buildings with membrane systems 10 to 15 years old showing surface weathering but no systemic seam failures or structural deck issues.

Who silicone coating is absolutely wrong for in SoMa: Any roof where moisture testing reveals wet or saturated insulation, where structural deck deflection has created permanent ponding zones, or where the building’s drainage capacity is already inadequate for SoMa’s storm intensity — coating a membrane without correcting an underlying drainage deficiency simply defers the same flooding risk. We test first, always, and recommend tear-off and replacement where the underlying structure or drainage system requires it.

Metal Roofing in SoMa, SF | 94103, 94105 & 94107 | Standing Seam, Architectural Accent & Industrial Specialists

Metal roofing in SoMa most often appears as architectural accent work on converted warehouse buildings, standing seam systems on contemporary infill construction, and custom flashing and coping work on the district’s mix of historic industrial and modern high-rise buildings.

Metal roofing applications in SoMa:

  • Standing seam steel installations on contemporary infill and adaptive-reuse projects
  • Custom parapet coping and cornice cap fabrication for warehouse and loft building facade restoration
  • Architectural metal accent roofing on converted industrial buildings preserving original character
  • Metal flashing and counter-flashing fabrication for rooftop equipment curbs and penetrations
  • Gutter and downspout system fabrication and replacement on buildings transitioning from original industrial drainage systems

Material selection for SoMa’s urban environment: While SoMa does not face the aggressive marine salt exposure of San Francisco’s coastal neighborhoods, its urban industrial environment — proximity to vehicle traffic corridors, Bay Bridge approach roads, and general city air quality — still calls for corrosion-resistant specifications on exposed metal work. We specify Kynar 500-coated steel and aluminum for standing seam and architectural applications, with factory-sealed cut edges wherever possible.

Waterproofing Services in SoMa, SF | 94103, 94105 & 94107 | Best Rooftop Deck, Amenity Space & Below-Grade Solutions

SoMa’s condo towers, converted lofts, and mixed-use buildings are defined by their rooftop decks and outdoor amenity spaces — a defining lifestyle feature of the district that also represents one of its highest-risk waterproofing categories when improperly detailed.

Waterproofing services we provide in SoMa:

  • Heavy-duty pedestrian and furniture-load-rated deck waterproofing using polyurethane and fiberglass-reinforced systems on rooftop amenity decks, gardens, and common-area outdoor spaces
  • Below-grade waterproofing on buildings with basement or below-grade parking, particularly relevant given SoMa’s high water table and fill-soil conditions
  • Planter box, green roof, and rooftop garden waterproofing membrane installation — increasingly required on new SoMa development under current stormwater management codes
  • Parapet wall through-wall flashing and coping repair on both converted industrial buildings and modern construction
  • Light well and interior courtyard waterproofing on mixed-use buildings with complex roof geometries
  • Podium deck waterproofing between below-grade parking structures and above-grade residential or commercial space — a construction type common throughout SoMa’s newer developments

The SoMa waterproofing standard: Standard waterproofing specifications used elsewhere in San Francisco frequently underperform on SoMa’s amenity-heavy rooftop decks, which see far heavier foot traffic, furniture loading, and planter drainage demands than typical residential decks. We specify enhanced-durability polyurethane and elastomeric systems engineered for high pedestrian traffic and long-term UV exposure on every SoMa amenity deck installation.

Skylight Installation in SoMa, SF | 94103, 94105 & 94107 | Monitor Skylight & Modern Skylight Specialists

SoMa’s converted warehouse and loft buildings frequently retain original monitor skylights and clerestory glazing — architectural features that define the district’s adaptive-reuse character but require specialized waterproofing knowledge most standard skylight installers lack. We handle both historic monitor skylight restoration and reflashing on converted industrial buildings, and modern skylight installation on new construction and contemporary renovations throughout the district. Every skylight curb is integrated with code-compliant base flashing and detailed to accommodate the building’s specific structural movement characteristics, whether that’s an aging timber-framed warehouse or a new mid-rise on a deep pile foundation.

How to Find the Best Roofer Near Me in SoMa | Top Local Hiring Standards

Every experienced SoMa property owner or building manager has a story about hiring a contractor who didn’t understand the district’s structural and drainage realities — and paid for it with a flooded ground floor or a failed rooftop equipment installation. Here is what our local clients wish they had known before signing:

  • Ask specifically about structural assessment on older buildings: If a contractor is willing to quote a re-roof on a converted warehouse without inspecting the original decking and framing, they are guessing at the structural capacity of your roof
  • Confirm drainage capacity is part of the scope, not an afterthought: Given SoMa’s documented flooding history, any roofing project that doesn’t include a drainage capacity assessment is incomplete
  • Get at least three bids and compare scope line by line, not just total price: A bid significantly below comparable quotes often means skipped structural assessment, undersized drainage, or subcontracted labor
  • Insist on San Francisco DBI permits, including structural review where applicable: Converted and mixed-use SoMa buildings frequently require additional permit review that a generic residential contractor may not know to pursue
  • Demand photo-documented estimates from an estimator who walks the full roof: Rooftop equipment, drainage points, and structural deck condition are not visible from the ground or from a single rooftop photo

Frequently Asked Questions: Best Roofing Near Me in SoMa, San Francisco

It depends entirely on the condition of the original structural decking, which is why we perform a full structural assessment before recommending any membrane system. Many SoMa warehouse conversions have century-old timber decking that performs well structurally but requires careful load consideration before adding a new membrane system. We also assess any existing monitor skylights or clerestory glazing as part of the same evaluation, since these original architectural features often require specialized waterproofing integration.

Yes, without exception. Full roof replacement and structural repair in 94103, 94105, or 94107 requires a DBI permit, and converted industrial and mixed-occupancy buildings frequently require additional structural or occupancy review. We manage the complete permit lifecycle, including any additional review pathway specific to adaptive-reuse buildings.

Silicone coating is a legitimate, cost-effective option when the substrate is confirmed dry and the underlying drainage capacity is adequate. Given SoMa’s flooding history, we always assess drainage capacity as part of any coating evaluation — coating a membrane without correcting an inadequate drainage system does not solve the underlying risk. We test first and give you a data-based recommendation.

SoMa sits at a lower elevation than most of San Francisco and is served by sections of the combined sewer system that are well documented to surcharge during heavy storms. When the municipal system backs up, your roof’s own primary and secondary drainage becomes the only line of defense against interior flooding. We size and assess drainage capacity on every SoMa project specifically because of this documented risk.

Yes, and SoMa’s comparatively fog-free microclimate makes solar significantly more productive here than in San Francisco’s western neighborhoods. We install Title 24-compliant TPO systems with attachment specifications engineered for your solar installer’s load requirements, and we coordinate rooftop equipment layout to avoid conflicts between HVAC, existing infrastructure, and new PV arrays.

We assess the existing equipment layout, anchoring condition, and seismic bracing compliance as part of every commercial project scope. Rooftop equipment on SoMa tech offices is often added over time by different tenants without a coordinated plan, so part of our process includes reviewing whether existing curbs and anchoring meet current code before any new membrane work proceeds around them.
