In Washington, compliance is not just about avoiding penalties, it’s about protecting lives and maintaining structural integrity across all types of roofs.

What are the Roof Material and Structural Code Requirements?

Proper installation instructions must be followed for all roof assemblies to ensure code compliance. Asphalt shingles and metal panels must be applied in accordance with their manufacturer installation guides.

I am requesting roof replacement bids. One company tells me I need to block the gable-end vents in the attic. I have two in the attic space. The other companies did not mention this at all. Do these need to be closed off?
