The Eastside default, installed the way it should be: full tear-off, proper underlayment, new flashing and corrected ventilation.
Composition shingle is the most common roof on the Eastside, and the difference between a fifteen-year roof and a twenty-five-year roof is almost never the shingle — it is the underlayment, the flashing and the ventilation underneath it. Top Line installs architectural asphalt shingle roofs across the Greater Eastside, with the whole assembly done properly.
Three-tab shingles are flat, lighter, cheaper and shorter-lived. Architectural (also called dimensional or laminated) shingles are heavier, layered for depth, hold up better to wind, and carry longer manufacturer warranties. On the Eastside, architectural is the standard specification and three-tab is generally a false economy — the cost difference over the life of the roof is small and the performance difference is not.
Manufacturers offer shingles with copper-containing granules that inhibit the blue-green algae responsible for the black streaking you see on roofs across the Puget Sound region. In a shaded, damp climate this is not a cosmetic upgrade — the same conditions that grow algae grow moss, and keeping organic growth off the surface directly extends the roof.
A sealed pipe boot and a ridge vent.
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. Architectural shingle rather than three-tab, algae-resistant granules where the roof sits under tree cover, synthetic underlayment instead of felt, ice-and-water membrane where water concentrates, and new flashing at every intersection. The shingle is the cheapest part of the decision — what goes under it is the roof.
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.
We get on the roof, photograph what we find and show you the real condition. No sales pitch on a first visit.
One document: scope, materials by name, timeline, price. Nothing is added later without your approval.
One accountable team, start to finish. Property protected before tear-off, and you know each morning what happens that day.
Magnet sweep for nails, debris hauled out, and we walk the property with you. You sign off when it is right.
Material choice drives cost, lifespan and how the roof handles nine months of rain. Here is what we install and maintain.

Typically eighteen to twenty-five years, but tree cover, ventilation quality and how quickly moss is dealt with move that number more than the shingle brand does. A well-ventilated roof in the sun that gets cleaned every couple of years will outlast a shaded, poorly ventilated roof of the same product by years.
We install the major North American shingle systems and recommend based on your roof, your budget and the warranty structure you want. We name the specific product going on your roof in the written quote, so you can compare it against any other bid line for line.
On a house you intend to keep, yes. Architectural shingles are heavier, handle wind better and carry longer warranties, and the price difference is modest relative to the total project.
Blue-green algae, extremely common across the Puget Sound region. It is primarily cosmetic on its own, but it indicates the surface stays damp — which is the same condition that grows moss, and moss is not cosmetic.
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.
