Commercial Roofing Contractor
Seattle, Washington
Vasa Construction LLC is a commercial roofing contractor in Seattle, Washington, serving offices, retail spaces, warehouses, and multifamily buildings throughout the Puget Sound region. A leak over a sales floor is not a maintenance ticket, it is lost revenue by the hour, so we phase work around your operating schedule rather than against it. For 25+ years we have installed, repaired, and maintained TPO, PVC, and modified bitumen assemblies, along with the drains, curbs, and terminations that decide whether any of it stays watertight. Every visit closes with photographs and written findings. Get your free commercial roofing estimate today!

Property managers care about two things beyond price, disruption and predictability, and we plan around both. Crews stage after hours or in phases so tenants keep operating, and we hand over condition reports that let you budget rather than react. Every visit is documented with photographs and written findings.
TPO and PVC Membrane Roofing
Single-ply sheets welded at the seams create one continuous waterproof plane. Reflective white surfaces also push summer heat back off the building, which matters on any structure carrying significant rooftop mechanical equipment.
Modified Bitumen Systems
Torch and cold-applied bitumen still earns its place on buildings with heavy foot traffic or complicated rooftop layouts. Multiple reinforced plies give redundancy that a single membrane layer cannot quite match.
Commercial Roof Repair
Targeted work keeps a serviceable roof in service. Seam repairs, flashing rebuilds, curb reworks, and patching around new equipment penetrations all get scheduled around your operating hours rather than against them.
Multifamily and Apartment Roofing
Buildings full of residents cannot simply close for a week. Phased tear-off, daily dry-in, and posted schedules let occupants stay in place while the work moves methodically across the structure section by section.
Roof Drain and Scupper Repair
Standing water is a symptom, not a design feature. Clearing, resetting, and rebuilding drains, scuppers, and overflow paths restores flow so the membrane is not carrying weight it was never intended to hold.
Roof Condition Reports and Asset Planning
Owners with several properties need numbers, not impressions. Documented inspections with photographs, remaining service life estimates, and prioritized repair recommendations turn roofs into a planned line item across your capital budget.

Commercial Roofing Systems
We install and service four main flat roofing systems. Building use drives the choice more than preference does, because a restaurant with grease-laden exhaust and a warehouse with rooftop units place completely different demands on the same square footage.
TPO Membrane
The most widely specified single-ply system in the region. Heat-welded seams, strong reflectivity, and a friendly cost per square foot make it the default for offices, retail, and light industrial buildings.
PVC Membrane
Worth the premium wherever grease, chemicals, or restaurant exhaust reach the roof surface. PVC resists that exposure far better than TPO and holds its welded seams reliably under the same conditions.
Modified Bitumen
Multiple reinforced plies deliver redundancy that single-ply cannot. It suits complicated rooftop layouts, high foot traffic areas, and buildings where a puncture in one layer should not become an immediate leak.
EPDM Rubber
A proven, economical option for large uninterrupted areas with few penetrations. Wide sheets install quickly and the material handles temperature swings well, though seams need more attention than welded systems.

Protect Your Business With Dependable Roofing Performance
Every commercial roof decision lands on the same tension. Doing the work costs money now, and postponing it costs more later, usually on the worst possible night of the year. Information is what breaks the deadlock. Knowing which seams are failing, how much service life remains, and what order the repairs should follow turns an anxious guess into a schedule you can defend at a budget meeting. Vasa Construction LLC produces that documentation for offices, retail, and multifamily properties across Seattle, Washington, then works around your hours. Send the address and the square footage through our contact page.
What does proper roof ventilation actually involve?
Air must enter low at the soffits and exit high at the ridge in roughly equal volume. Undersized intake is the common failure, and it leaves attics damp no matter how many vents sit on top.
How is the house protected while the roof is open?
Vasa Roofing West Seattle LLC tarps exposed sections, dries in each area before the crew leaves, and covers landscaping and siding throughout. Homes across Seattle, Washington stay sealed every night of the project.
Frequently Asked Questions
How long does a commercial flat roof last?
Well-maintained TPO and PVC systems generally run 20 to 30 years, modified bitumen slightly less. Drainage quality, foot traffic, and how quickly seam issues get addressed move that range considerably.
What is the practical difference between TPO and PVC?
Both are welded single-ply membranes. PVC resists grease, chemicals, and restaurant exhaust better, while TPO usually costs less per square foot. Building use, not preference, should decide between them.
Can an existing roof be recovered instead of replaced?
Sometimes. Recovery works when the substrate is dry and only one layer exists. Wet insulation, multiple existing layers, or structural load limits rule it out and make full replacement the safer path.
How often should a flat roof be inspected?
Twice yearly, plus after any significant wind event. Vasa Construction LLC inspects commercial roofs across Seattle, Washington in spring and fall, when problems are easiest to catch early.
Why does water pond on my roof after it rains?
Ponding means drainage has failed or the deck has deflected. Blocked drains, crushed insulation, added rooftop equipment, and settled framing are the usual causes, and each one has a different fix.
Will the work disrupt tenants or business hours?
It does not have to. We phase the work, stage material outside traffic paths, and schedule noisy operations around your hours so occupants and customers keep moving through the building normally.
What causes most commercial roof leaks?
Details, almost never the field. Failed seams, deteriorated pipe boots, rusted equipment curbs, loose termination bars, and penetrations added later without proper flashing account for the overwhelming majority of the calls we take.
Do commercial re-roofs need a permit in Seattle?
Generally yes. Commercial and multifamily re-roofing typically requires permitting even where detached houses do not, and Vasa Construction LLC manages that process for Seattle, Washington property owners.
