Replacing a roof in Redmond.
Do I need a permit to replace a roof in Redmond?
Redmond exempts lightweight roof coverings — composition or metal weighing less than 4 lb per sq ft installed. For heavier materials such as tile, or any structural work, check with the city, which has a re-roofing permit application. Rules change, so confirm with the city: Redmond residential permits.
Do older homes in Redmond cost more to re-roof?
Usually less. Half of Redmond’s homes were built in 1993 or later, so most roofs here are a first replacement over sheet decking. Older houses in the city can still hide soft decking or a second layer, found once the old roof is off. A contractor prices those on site — they are not in the planning range.
