Single-ply membrane, modified bitumen and metal systems for Eastside offices, retail, restaurants and multifamily buildings.
Top Line installs, repairs and maintains commercial roof systems across the Greater Eastside and the Puget Sound region — PVC, TPO, modified bitumen and metal. We work around your operating hours, keep the site controlled and safe, and put the full scope in writing before anything is torn off.
A commercial roof in this region is managing volume, not intensity. It rains for months, it does not dry out, and every low spot holds standing water. Ponding degrades membrane, grows moss and algae along seams, and finds any lap that was not welded properly. Add fir and cedar debris blocking drains and scuppers, and a roof that was fine in September is holding two inches of water in November.
We walk the entire roof and document seams, penetrations, drains and equipment curbs.
You get repair and replacement priced separately where both are viable, so ownership can make a real decision.
Work sequenced to keep the building operating.
Final walkthrough, photographs of completed detail work, and the paperwork your building file needs.
We schedule the work around your operation and phase it so entrances, parking and deliveries stay usable.
Perimeter protection, controlled debris handling and clear access routes. Your tenants and customers are not walking under an uncontrolled job.
Line-item scope your property manager or ownership group can actually review, plus documentation for the building file.
The site is left tidy each evening, not just at project close. Debris does not accumulate in your parking lot for a week.
The part you stop seeing the day the job is finished is the part that decides how long it lasts.
Premium products, not builder grade. Membrane specified at the right thickness for the building rather than the thinnest sheet that meets code, manufacturer-approved fasteners, plates and adhesives, and prefabricated corners and curb wraps instead of field-improvised detail. The cheap version of a commercial roof shows up as a call-back in year four.
Installed the way the manufacturer specifies. Material warranties are conditional on installation. Get the fastener pattern, the flashing detail or the ventilation wrong and the coverage behind the product is gone. We install to the published specification, so the warranty you paid for stays intact.
Material choice drives cost, lifespan and how the roof handles nine months of rain. Here is what we install and maintain.

Yes. We phase commercial work so that entrances, parking and delivery access stay usable.
PVC is the stronger choice where there is grease exhaust, chemical exposure or persistent ponding, which is why it is the default over commercial kitchens. TPO costs less and performs well on clean, well-drained roofs.
The same standard on every service. Roofing, gutters, repairs, cleaning, new construction — one materials policy and one standard of detail, whether it is a full replacement or a single flashing repair.
