Roofing for new commercial, industrial and residential construction across the Greater Eastside, coordinated with the project schedule and the other trades.
Top Line works as the roofing contractor on new construction across the Greater Eastside and the Puget Sound region — single-family homes and custom builds, commercial buildings, and industrial facilities. We also handle the roof on additions, dormers, ADUs, garages and shops, which is where a lot of new-construction roofing actually happens on an established Eastside lot.
On a new build the roof is designed before it is installed. We read the plans, flag the details that will cause problems later — valley geometry that concentrates water, a low-slope section drawn as if it were pitched, ventilation that will not balance once the insulation goes in — and we raise them while they are still drawings rather than after the framing is up.
The same team and the same standard, scaled to the building.
Custom homes, spec homes, ADUs, additions, dormers, garages and shops. Complex roof geometry is normal on Eastside custom work, and every intersection is a flashing detail that has to be built rather than improvised.
Offices, retail, multi-family, mixed use. Mostly low-slope membrane with rooftop equipment, drains, scuppers and curbs, coordinated with the mechanical trades before the membrane goes down.
Warehouses, shops and production facilities. Large-span metal panel and membrane systems, high penetration counts, and a deck that has to stay watertight over a building where downtime is expensive.
On a new build you get to choose the roof rather than inherit it. Here is what we install and what each one is actually good at.
On a new build nobody sees what went under the roof. That is exactly why it is worth specifying properly.
Builder-grade is the default on most new construction because it is the cheapest line on the bid. We quote the premium tier instead — heavier gauge, better underlayment, better sealants and fasteners, manufacturer-approved components throughout.
Material warranties are conditional on installation. Fastener pattern, flashing detail, ventilation, underlayment coverage — get one wrong and the coverage behind the product is compromised.
Roofing, gutters, repairs, cleaning — there is no cheaper line of work where the standard quietly drops. One materials policy and one standard of detail, on a large commercial deck or a single dormer.
Four steps, no mystery. The builder and the owner both know what happens next.
We price from the drawings, flag the details that will cause problems, and give you one written scope with the materials named. No allowances that get revised later.
We coordinate with the general contractor so the roof goes on when the framing is ready, not two weeks after. Drying the building in is the gate everything else waits behind.
Penetrations, curbs and equipment coordinated with the mechanical and solar trades before the roof closes, so nothing gets cut in afterwards.
Walkthrough with the builder and the owner, warranty documentation handed over, site cleaned and magnet-swept before we leave.
In Redmond and Sammamish, and in Bellevue, Medina and Seattle, we roof new commercial and industrial buildings, custom homes, additions and ADUs for owners and general contractors, with dry-in coordinated with the other trades.

Yes. Topline Roofing and Construction.com works with general contractors and property owners to define the roofing scope for new construction and additions. We review the proposed roof system, installation details and scheduling requirements before work begins.
It depends on the roof geometry, the structure, the building’s use and how long the owner intends to hold it. We will price more than one option on the same drawings so the comparison is real rather than theoretical.
Yes — multiple planes, dormers, skylights, and low-slope sections meeting pitched roofs are normal on Eastside custom work. Complexity lives in the flashing detail, and that is the part we build rather than improvise.
Yes, seamless aluminum formed on site and sized to the actual roof area draining into each run. Doing the roof and the gutters together means the roof edge, the fascia and the drainage are detailed as one system.
We get on your roof, photograph what we find, and tell you whether you are looking at a repair, a cleaning or a replacement. No charge and no pressure.
Premium materials only, on every job — installed to the manufacturer specification so the warranty stays intact.
