Commercial Roofing & Waterproofing in Washington
Waterproofing and commercial roofing for Washington properties facing persistent moisture, heavy rainfall, and drainage challenges throughout the year.

West of the Cascades, the Roof Is Never Really Dry.
Most of the country's roofing failures start with a storm. Western Washington's start with persistence.
Sustained moisture is the design condition. Eight months of rain with low evaporation means an assembly that takes on water has no opportunity to dry out. Moisture spreads laterally through the insulation, degrades R-value, corrodes the deck, and surfaces as a leak nowhere near where it entered. A membrane can look entirely serviceable over saturated insulation, which is why core cuts and moisture surveys matter more here than in almost any market we work.
Drainage decides service life. A roof that holds standing water in a dry climate loses years. In this one it loses far more, because the water never leaves and organic growth compounds it. Positive drainage, adequate primary drains, and real overflow provisions are the difference between a twenty-year roof and a twelve-year roof.
The work window is genuinely narrow. Adhesive and membrane application temperature and moisture limits are not negotiable, and installing outside them voids the manufacturer warranty. The reliable window is short and it fills early. Owners who plan a replacement in January get the summer they want. Owners who call in June generally don't.
East of the Cascades is a different state entirely. Spokane, the Tri-Cities, and the Columbia Basin carry a semi-arid climate with real snow load, freeze-thaw cycling, and wide thermal swing — closer to Colorado than to Seattle. Same jurisdiction, opposite assembly.
What is AVID?
AVID Roofing & Waterproofing is a commercial operator with more than $300 million installed over its leadership's careers. 205 combined years of leadership and field supervision, every bit of it earned in the field — installer, foreman, estimator, system designer — before anyone here ran anything. Every project is assigned to and fully supervised by a project manager whose name you'll know by the end of the first walk, and who sends you a written report every day the job is open.
We're manufacturer-certified with Sika, Siplast, Garland, Johns Manville, and FiberTite, and every system goes in to manufacturer specification.
We've worked in Washington. Full building envelope work on an operating pharmaceutical campus in Bothell — a facility that couldn't stop running while we were on it. Distance doesn't change the accountability structure: same named project manager, same daily written report, same core-cut assessment before anyone quotes a number.
What We Do In Washington
Commercial roofing. 60-mil TPO, PVC, EPDM, modified bitumen, and standing-seam metal systems installed to manufacturer specifications on buildings that remain open during the work.
Design-build reroof. Assessment, drawings, submittals, and installation under one contract. No consultant fee stacked on top of the install, and one warranty covering the full assembly instead of a finger-pointing match between the designer and the installer when something leaks.
Architectural sheet metal. Copings, fascia, edge metal, and through-wall flashings fabricated in-house to ES-1 wind uplift standards. Edge metal is where most North Texas roofs fail first — and in a corridor that takes hail nearly every spring, that detail is the difference between a repair and a claim.
Waterproofing and restoration. Water doesn't only come through the roof. Tilt-wall joints, window perimeters, plaza decks, parking structures, below-grade walls — the other half of the envelope.
Roof asset management. Biannual GPS-tagged inspections, a multi-year capital plan, and 72-hour storm assessments on covered properties. Deferred maintenance isn't saving money. It's scheduling a bigger bill without telling you the date.
24/7 emergency service.
Active leaks, storm damage, failed flashings. Temporary dry-in within four hours on storm-driven leaks, and the line is answered by a person authorized to dispatch.
Emergency Dispatch: 833-766-3003.
Who Hires Us in Washington
Life sciences and controlled environments. The Bothell, Seattle, and Eastside biotech and pharmaceutical corridor. Pressures, differentials, particulates, and vibration make roof work on a controlled-environment building a coordination problem before it's a roofing problem — and the building doesn't stop for the roof. We've done exactly this work in Bothell.
Distribution and logistics. The Kent Valley, the Tacoma and Seattle port footprints, and the I-5 and I-90 corridors. Large single-ply envelopes with heavy rooftop mechanical, where the limiting factor isn't crew size but how much roof you can open and dry before the next weather window closes — a serious constraint in this climate, and one that gets written into a phasing plan before anyone starts.
Food and agricultural processing. The Columbia Basin and Yakima Valley. Process exhaust, washdown, cold storage, and refrigerated envelopes — where vapor drive reverses, and retarder placement decides whether the assembly survives. Work phases around shutdown windows and shift changes.
Data centers and mission-critical facilities. Central Washington's data center corridor. Continuity of operations governs everything; roof penetrations are coordinated against critical systems, and nothing gets opened that can't be closed the same day.
Multi-site owners and asset managers. A portfolio spanning both sides of the Cascades is two climates and two assembly specifications. Roof asset management means biannual GPS-tagged inspections documented to a single standard, a condition history that builds over time, and a consolidated multi-year capital plan.
Healthcare, education, and municipal. Hospital campuses across Puget Sound, the state university system, school districts, and public facilities. ICRA-aware scheduling. Campus work is summer work — and here the summer window is the entire schedule.

Washington Commercial Roofing Frequently Asked Questions:
Start with a complete roof and building-envelope assessment. Water may enter through the membrane, parapet walls, coping, flashing, rooftop penetrations, or exterior wall joints and appear far from its actual source. Condensation within the roof assembly can also resemble a leak. AVID uses visual inspections, moisture testing, core cuts, and, when appropriate, targeted water testing to identify the source before recommending repairs or replacement.
The reliable window here is short and it fills early. Adhesive and membrane application limits on temperature and surface moisture aren't negotiable, and installing outside them voids the manufacturer warranty — which defeats the purpose of buying a certified system. Emergency dry-in and most repairs happen year-round. Full replacements get scheduled into the dry window, which means planning in winter for summer work. We'll tell you plainly which category your project falls into rather than taking the job and hoping.
Yes. AVID can serve commercial properties on both sides of the Cascade Range. Eastern Washington’s colder winters, hotter summers, greater snow exposure, and larger temperature swings require different planning than those of the wetter marine climate in western Washington. We evaluate each building’s location, roof deck, insulation, drainage, and structural conditions before recommending an assembly.
The same way a local one does. One named project manager is assigned before the contract is signed and stays until the job closes. You get a written report every day the job is open — not a summary at the end. The assessment happens on site with core cuts before anyone quotes a number. Logistics and mobilization get priced into the proposal openly rather than appearing later as a change order. We've done full envelope work on an operating campus in Bothell on exactly that structure.
