If you live within sight of saltwater in the San Juan Islands, your roof faces a threat that most mainland homes never worry about: airborne salt. It rides in on the wind, settles into every seam and screw head, and quietly eats through the cheapest, most invisible part of your roof system — the fasteners. A roof can look flawless from the driveway while the screws holding it down are rusting into dust. Understanding why this happens, and what to demand instead, is the diff
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
Every island homeowner eventually looks up at a roof streaked green and black and thinks, "I could just power-wash that." Please don't. In our wet, shaded climate, a roof grows moss, algae, and lichen the way a north-facing rock grows a beard. Cleaning it is worthwhile — but the wrong method strips granules, drives water under shingles, voids warranties, and shortens the life of a roof you paid dearly to install. This guide walks through how to clean an island roof safely,
If you have read anything about roofing in the last few years, you have probably run into the term "cool roof." The idea sounds appealing: a roof engineered to reflect sunlight and shed heat, so your home stays comfortable and your energy bills drop. But cool roofs were designed for hot, sun-baked climates like Arizona and Southern California. Out here in the San Juan Islands, where we measure our summers in weeks and our rain in dozens of inches, the calculation is very di
