Metal Roof Installation for San Juan Island's Climate
San Juan Island roofs fail by geography. On the west side, wind off Haro Strait works shingle edges loose and drives salt into every exposed fastener; in the tree-lined valleys, shade grows moss fast enough to halve an asphalt roof's service life. Metal answers both ends of the island — concealed-fastener systems engineered for coastal wind zones, and a smooth surface moss can't root in.
The install is where a 50-year roof is won or lost: underlayment lapped for wind-driven rain, valleys and penetrations flashed in matching metal, and panels allowed to expand and contract through the island's freeze-thaw swings without stressing a single fastener. Out-island, that starts with logistics — long panels are delivered to your site by our supplier, by ferry, before the crew's start day.
We're an exterior contractor first — when the roof and siding are planned together, the wall-to-roof flashing details integrate instead of colliding, and one crew owns the whole envelope. To be direct about scope: we install metal roofing only — no asphalt shingle roofs.
Standing Seam Metal Roofs
The premium system: vertical panels with concealed fasteners locked at raised seams, so no screw head ever faces the weather. On San Juan Island it's the configuration we recommend for every strait-facing roof — maximum wind resistance where Haro Strait exposure is strongest, clean modern lines on view homes, and nothing for salt to corrode as the roof ages.
Exposed-fastener panels remain an honest budget option for barns, outbuildings, and low-visibility valley roofs — the island's farm properties use plenty of them, and we quote both and tell you where each belongs.
Metal Roof Over Shingles?
Sometimes, honestly, yes. Code allows metal over a single existing shingle layer when the deck underneath is sound, and it saves tear-off cost and landfill weight. The catch is the word sound — over moss-damaged shingles hiding soft decking, an overlay locks the problem in.
We probe the deck at your estimate and quote overlay and tear-off as separate line items where overlay is viable — the decision is yours, made with the facts on the table.
