The longest-lasting roof you can put on an Eastside home — and the one that handles rain, needles and moss best.
Metal is the longest-lasting roof system available for Eastside homes and the best performer in a wet climate. Top Line installs standing seam and metal panel roofs across the Greater Eastside and the Puget Sound region — concealed-fastener systems that shed rain and fir needles, resist moss and typically outlast two or three composition roofs.
Metal does not host moss the way an asphalt shingle does. There is no granular surface for spores to establish in and no keyway between courses for a colony to wedge open. On a shaded, tree-covered Eastside lot — where a composition roof loses years to moss — that difference alone can be worth the premium.
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.
A properly installed standing seam roof is commonly a multi-decade system — meaningfully longer than composition in the same conditions.
No granular surface and no keyways. Moss struggles to establish where it destroys an asphalt roof.
Smooth panels move rain fast and let fir needles slide off instead of matting into courses.
Reflects solar gain in summer and needs very little from you beyond keeping valleys and gutters clear.
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, a premium coating system rather than the base finish, concealed clips that let the panel move with temperature, and matching flashing and trim fabricated to the roof instead of adapted from stock. Metal is a decades-long decision, and the gauge and the coating are what make it one.
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.

On shaded, tree-covered lots in Sammamish, Medina and across the Eastside, a metal roof sheds rain and fir needles and does not host moss the way shingles do. We install standing seam and metal panel systems in Bellevue, Redmond and Seattle too.

Substantially more upfront — metal is one of the higher-cost systems to install. The trade is service life: a properly installed standing seam roof commonly outlasts two or three composition roofs, so measured as cost per year it is competitive or better. We measure your roof and put an exact number in writing rather than quote a range.
No, not on a residential installation. The panels go over solid decking with underlayment, with attic space and insulation below.
Far less. There is no granular surface for spores to grip and no keyway between courses for a colony to open up.
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.
