Large-format single-ply membrane for warehouses, distribution centers and manufacturing facilities.
Top Line works on industrial roofs across the Puget Sound region — warehouses, distribution centers, light manufacturing and self-storage. Large-format PVC and TPO membrane, installed in phases that keep the facility running.
Scale changes the problem. On a large roof, a drainage design that is slightly wrong does not cause a damp ceiling tile — it causes structural loading from standing water. Thermal movement across long metal spans opens fasteners and seams that were fine on a smaller building. And the roof is carrying process equipment, exhaust, condensate lines and roof traffic that a retail roof never sees.
Full roof walk with documentation of drainage, seams, fasteners, curbs and equipment.
Written scope broken into phases with a schedule built around your operating hours and dock activity.
Bay by bay. Interior protection below the active work area, and controlled access throughout.
Photographed detail work and as-built notes for your facilities file.
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. Heavier-gauge panel, industrial-grade fasteners and sealants rated for the movement a large span actually sees. On a building where downtime costs money, the material spec is not the place to save a few thousand dollars.
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. Industrial work is phased by section or bay so operations continue.
Yes, and it should be fixed before any new membrane goes down. Tapered insulation, additional drains, scupper enlargement or overflow provisions — the right answer depends on the structure and the existing drainage.
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.
