The Complete Guide to Roof Moss Removal in the Pacific Northwest
If you live in the Pacific Northwest, you know moss. It softens the woods, coats the fences, and given the chance, it takes over roofs. In the San Juan Islands, where roughly 40 inches of rain falls each year and shaded north slopes sit under towering Douglas fir, moss is not just a look. It is a slow, patient force that lifts shingles, traps moisture, and shortens the life of an otherwise healthy roof. This guide walks you through why moss grows, how to remove it safely, a
A leaking or fogged skylight is one of the more anxious roofing problems for an island homeowner, because it sits at the intersection of two systems: the glass unit itself and the roof it penetrates. On the San Juan Islands, with roughly 40 inches of annual rain, wind-driven storms, and salt air working on every metal component, a skylight problem rarely stays small if it is ignored. The core question is always the same. Do you repair the skylight you have, or replace it en
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
Slate has crowned fine homes for centuries, and for good reason: it is stunning, fireproof, and can outlast the building beneath it. But natural slate is heavy, expensive, and unforgiving to install, which has pushed many homeowners toward synthetic slate, a modern composite that mimics the look at a fraction of the weight. For San Juan Islands homes, where 40 inches of annual rain, salt air, and strong west-side winds test every material, choosing between the two is not ju
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
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
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,
Winter in the San Juan Islands is not defined by snow. It is defined by water and wind. Roughly 40 inches of rain fall here each year, and the heaviest of it arrives in November, driven sideways by gusts that run about 20 percent stronger on the west side than they do over in Anacortes. Add salt air off every shoreline and the moss that thrives on shaded north slopes under Douglas fir, and you have a climate that finds every weak point in a roof. The good news is that a few
