Commercial Roof Inspection
A Commercial Roof Inspection in Tacoma is not a generic checklist exercise — the building stock here is genuinely diverse, and the failure modes that matter on a Port of Tacoma logistics warehouse are completely different from those on a Sixth Avenue retail storefront, a JBLM contractor facility in Lakewood, or a transit-adjacent mixed-use building near Tacoma Dome Station. We structure every inspection around the specific building type, roof system, age, and exposure conditions before we set foot on the membrane.
For port and industrial buildings — the large-format warehouses along Marine View Drive, the Tideflats manufacturing facilities, and the Frederickson Industrial Center buildings — the inspection priorities are fastener condition on metal roofs, drain sump clearance and sizing, edge metal corrosion from marine air exposure, and the condition of penetration flashings around the dense HVAC and exhaust equipment that industrial buildings carry. A 200,000-square-foot warehouse roof with 40 penetrations and six interior drains requires a systematic grid-walk to document every condition — we do not trust a windshield survey or a cursory perimeter walk on buildings of this scale.
JBLM contractor buildings in the Lakewood, Spanaway, and University Place corridor present a specific inspection challenge: access coordination. Many of these buildings require advance notice, badging, or escort for non-tenant contractors. We schedule inspections with sufficient lead time to complete the access paperwork, and we document findings in the format that facility managers and government lessees require — typically a written condition report with photos keyed to a roof plan drawing, rather than informal notes.
Tacoma Dome District buildings — the mixed-use commercial, office, and light industrial stock clustered around the transit hub — tend to be a mix of ages and systems. We find BUR on buildings from the 1970s sitting next to TPO-covered additions from 2010 on the same structure. An inspection on these properties has to cover the interface between old and new systems, because the transition flashing between a legacy BUR field and a newer single-ply addition is one of the highest-probability leak locations on any mixed-system roof.
Retail buildings — Tacoma Mall and the surrounding Pacific Avenue commercial corridor, plus the neighborhood retail clusters in the Proctor District and Sixth Avenue — are inspected with an emphasis on HVAC curb flashings, rooftop equipment condensate drainage, and parapet cap conditions. Retail buildings accumulate rooftop equipment over time as tenant fit-outs add supplemental HVAC, and each penetration cut into the membrane without proper re-flashing is a potential entry point. We inventory every penetration against the building's original permit drawings when available.
Waterfront properties along the Thea Foss Waterway and Old Town Tacoma face the highest marine air corrosion exposure in the Tacoma market. Inspection on these buildings always includes close examination of edge metal, through-wall scupper conditions, and any metal coping at parapets. Galvanic corrosion between dissimilar metals — aluminum copings fastened with steel screws, for example — progresses visibly within five to seven years on directly bay-facing buildings. We document metal condition with photos and note fastener type and condition for every perimeter condition we can access.
Infrared scanning is a standard part of our inspection protocol on any roof over 10,000 square feet where the owner is considering a repair program, re-cover, or replacement. The scan identifies wet insulation that is invisible to a walking survey and changes the repair-versus-replace calculus fundamentally. We conduct infrared scans after sunset when the temperature differential between wet and dry insulation is greatest — scheduling a 9 PM arrival at a Port facility or industrial building is normal practice for us.
Every inspection produces a written report with findings organized by priority: immediate action required, action within 90 days, monitor at next inspection. We provide photo documentation tied to a roof diagram, a summary of estimated repair costs by priority tier, and a remaining useful life estimate for the existing system. Owners managing multi-building portfolios across Pierce County use our inspection reports as budget inputs for capital planning cycles.
Roof Questions
How often should a commercial roof in Tacoma be inspected?
Twice per year is the standard we recommend for most Tacoma commercial buildings — once in late summer to identify and address issues before the November rainy season begins, and once in early spring to assess winter damage. Port and Tideflats buildings with marine air exposure, and any building with a history of leaks, benefit from three inspections per year. Buildings under active maintenance programs typically get a brief drain-clearing visit in October as well.
What does a Commercial Roof Inspection cost in Tacoma?
Inspection fees depend on roof size, system complexity, and whether infrared scanning is included. A straightforward inspection on a single-system building under 20,000 square feet runs less than a large industrial building with multiple roof levels, mixed systems, and 40-plus penetrations. We quote inspections based on building footprint and access complexity. The cost of a missed failure — a November emergency repair or business interruption from interior water damage — dwarfs the inspection fee on any building.
Can you inspect a roof while the building is occupied and operating?
Yes, and the majority of our inspections happen on occupied buildings. Roof-level inspection does not require interior disruption. The exception is infrared scanning, which requires access during nighttime hours and may require brief interior access to correlate thermal anomalies with interior ceiling conditions. We coordinate all access with facility management in advance.
What is included in your inspection report?
Our reports include a written condition narrative, photographs keyed to a roof plan, a prioritized deficiency list with recommended action timelines, a remaining useful life estimate for the current system, and a rough-order cost range for identified repairs. For portfolio owners, we can provide reports in a standardized format that feeds into capital planning spreadsheets or asset management software.
Do I need an inspection before filing a wind or storm damage insurance claim?
A documented pre-storm condition inspection is strong evidence in any insurance claim because it establishes baseline condition before the event. If you do not have a recent pre-storm inspection, a post-event inspection documenting fresh damage indicators — fractured membrane, displaced flashing, impact marks — is still valuable. We provide inspection reports formatted to support insurance claim submissions and can speak with your adjuster's field inspector if needed.
