Roofing in Aberdeen, WA

Aberdeen holds the oldest housing stock on this entire list and it is not close. The census puts the median year built at 1948, thirteen years earlier than the next town, with 61 percent of its 7,040 units raised before 1960 and only 7.4 percent since 2000. Median value stands at $237,300. Only 56.5 percent of it is owner occupied, so a large share of these roofs are a landlord's decision.

A 1948 median means most of these roofs sit on board decking rather than plywood, framed by people who assumed cedar shingle and ventilation through the gaps. Putting a modern asphalt system over that assembly without opening the eaves is how a sound-looking roof rots its deck from the inside in a decade.

This is also the only genuinely coastal exposure we work, and the record proves it. The South Coast weather zone carries three hundred and thirty high wind events in the federal file and the Central Coast a hundred and forty-eight, against two in the Lower Chehalis Valley zone twenty miles inland. Twenty miles inland the same weather system is a rain event rather than a wind one.

The dated events are specific. Gusts near seventy miles an hour brought trees down in Aberdeen on 28 February 1996. On 19 November 2012 a semi truck was blown onto its side in the middle of the Chehalis River bridge here while about 2,700 Grays Harbor customers lost power. In December 2022 spotters measured a quarter inch of ice.

So perimeter edge metal is where an Aberdeen scope spends its money, and it is not a preference. Tested edge metal fastened in the pattern it was tested in, a manufactured starter at the rakes rather than a reversed shingle, and fastening at the tight end of the published range for exposed corners.

We will not thin any of that down to match a cheaper bid, and we will tell you why in front of the roof. Wind takes a roof apart from the outside in and it starts at the edge, so a bid that saves money on the perimeter has saved it on the only part that fails first.

Aberdeen requires the permit and publishes two different wind numbers for the same city. Its roofing handout says the city sits in a special wind zone determined at 105 mph three-second gust, with no exceptions and all material installed to the manufacturer's high-wind schedule; its structural FAQ says 120.

Both are the city's own and nothing reconciles them, so we build to the higher and say why. Its handout also warns that most roofs here carry two or more layers, which forces a strip to the sheathing - and skip sheathing must then be sheeted in 7/16 OSB or half-inch plywood.

The downtown commercial stock is a separate discipline again. Older low-slope decks behind parapets, with box gutters and internal drains, where the honest first step is a moisture survey with logged core cuts and a wet percentage reported before anybody says the word recover. A wet percentage on a plan is worth more than three verbal opinions about the same roof.
