A new roof installation in Seattle typically costs $10,000 to $35,000 for residential homes, depending on material and roof size. K Single Corp has completed over 15,000 installations across King, Snohomish, and Pierce counties, with every project backed by a 10-year workmanship warranty.

A full roof installation includes more than laying new shingles or panels. We handle building permit applications, material ordering and delivery, full tear-off of the existing roof, decking inspection and repair, ice and water shield at all vulnerable areas, synthetic underlayment, proper flashing at every penetration and valley, and complete debris hauling and disposal. You do not need to coordinate any of these steps yourself.

Common Questions

Frequently Asked Questions

How much does a new roof installation cost in Seattle?
New roof installation in Seattle ranges from $10,000 to $35,000 for most residential homes, depending on the material, roof size, and complexity. Composition shingles run $10,000 to $18,000, while metal roofing ranges from $18,000 to $35,000. Commercial installations are priced per square foot.
How long does a new roof installation take?
Most residential roof installations take 2 to 5 days from start to finish. Larger homes, complex roof designs, or multi-material jobs may take a full week. Commercial installations vary from 1 to 3 weeks depending on building size and system type.
What is the best time of year to install a new roof in Seattle?
Late spring through early fall (May through October) is the ideal window for roof installation in Seattle. Drier weather means fewer delays and better adhesion for sealants and underlayment. That said, K Single Corp installs roofs year-round and takes precautions during wet weather to ensure quality.
Do I need a permit to install a new roof in Seattle?
In most cases, yes. Seattle and surrounding cities typically require a building permit for full roof replacements, especially if structural changes are involved. K Single Corp handles all permitting as part of our service, so you don't have to worry about the paperwork.
What happens to my old roof during installation?
We perform a full tear-off of your existing roofing material, inspect and repair the underlying decking as needed, install new underlayment and flashing, and then install your new roof. All old materials are hauled away and properly disposed of. We run magnetic nail sweeps on your property to catch any stray fasteners.
Can I stay in my home during a roof installation?
Yes. Most homeowners stay in their home during the installation. There will be noise from the work, but it does not affect the safety or livability of your home. We let you know what to expect before work begins.
What warranty comes with a new roof installation?
K Single Corp provides a 10-year workmanship warranty on all new roof installations. Material warranties are provided by the manufacturer and range from 25 to 50+ years depending on the product selected. We register your warranty and provide all documentation at project completion.
