If a roof has a weak point, it is almost never the wide-open field of shingles or panels. It is the transitions, the places where the roof meets a wall, a chimney, a valley, or a vent pipe. Flashing is the thin metal that seals those transitions, and on the San Juan Islands it does the hardest work on the roof. With roughly 40 inches of rain a year, wind that runs about 20 percent stronger on west-side exposures than in Anacortes, and salt air corroding anything cheap, flas
When a storm tears open your roof or a branch punches through the deck, the water does not wait for a repair appointment. A well-placed tarp is the difference between a contained problem and a ruined ceiling, soaked insulation, and a mold headache that outlasts the storm. Emergency tarping is a temporary measure, not a fix, but it is one of the most valuable skills an island homeowner can understand. In the San Juan Islands, where a November storm can pin down the ferries a
Most homeowners in the San Juan Islands think of their roof as a shield against the weather above it. That is only half the story. The air trapped underneath the deck matters just as much, and on islands that soak up roughly 40 inches of rain a year, poor ventilation quietly rots more roofs than any single storm. If you have ever seen a green carpet of moss creeping up a north slope or found a soft, spongy patch of plywood during a repair, ventilation was probably part of t
Understanding Roof Underlayment and Ice-and-Water Shield
Most homeowners judge a roof by what they can see: the shingles or metal panels on top. But the material that does the quiet, unglamorous work of keeping water out of your house is often the layer you never look at. Underlayment sits between the roof deck and the finish surface, and on a rainy island roof it can be the difference between a dry attic and a slow, hidden leak. In San Juan County, where roughly 40 inches of rain falls every year and November storms drive water
6 Reasons Island Roofs Cost More Than Mainland Roofs
Homeowners who move to the San Juan Islands from the mainland often get a jolt when the first roofing bid arrives. The same square footage that would cost one figure in Anacortes or Mount Vernon can run noticeably higher on San Juan, Orcas, Lopez, or Shaw. It is not price gouging. Island roofing carries genuine costs and demands that mainland jobs simply do not, and understanding them helps you budget honestly and judge whether a bid is fair. Here are the six biggest reason
Your roof does far more than keep the rain out. In the San Juan Islands, where mild but persistent damp weather rules most of the year, the roof is one of the biggest levers you have over comfort and energy bills. Heat escapes through poorly built roof assemblies in winter, and the same assemblies let living spaces overheat during our long summer evenings. The upgrades below focus on the roof itself, from the deck to the ridge, and each one earns its keep in a wet, wind-exp
Roofing in the San Juan Islands is a different game than roofing on the mainland. Salt air, relentless rain, moss, ferry logistics, and stiff west-side wind all conspire against shortcuts. The homeowners who spend the most money over the life of a roof are usually the ones who made an avoidable mistake early. Here are the seven that show up again and again on island homes — and how to sidestep each one. 1. Choosing Materials for the Mainland, Not the Islands The most
If you have an asphalt shingle roof, those tiny colored granules coating each shingle are not there for looks alone. They are the roof's sunscreen. The mineral surfacing shields the asphalt binder underneath from ultraviolet light, deflects heat, and adds fire and impact resistance. When granules start washing into your gutters faster than normal, the roof is telling you something. In the San Juan Islands, where roughly 40 inches of rain a year and salt-laden air work again
