Washington Sequoia Roofing did a spectacular job they arrived when they said they would, communicated on all aspects of the repairs truly went above and beyond what was expected I couldn't be more happy I would sincerely recommend this company on any roof or remodel!

We couldn’t be more happy with the job that was done on our Garage. The team was professional and went right to work, the Bid was a great price and the work was top notch great quality. They even went above and beyond found a problem with bracing and they went right to work and fixed the problem.
I can’t recommend this company enough. We have some more roof jobs in the future and this is our crew!

I had my complete roof replaced to include all the plywood. The job was completed in two days. Could not be happier with the work that was done. Afterwords there was absolutely no debris or sign of work in the yard or garden. Great care was taken to explain everything about the job, and no questions were left unanswered. Would definitely recommend them to any of my friends and family.

The average roof replacement cost for a residential home typically ranges from $7,000 to $15,000, depending on factors such as roof size, chosen materials, roof pitch, and labor rates in your area. Premium materials or complex designs may increase the price.
The cost to replace the roof of a commercial building typically ranges from $5 to $12 per square foot, depending on several factors such as roof size, material, labor rates, building type, and local code requirements.
Several factors influence roof repair cost, including the extent of the damage, roof accessibility, material type, labor costs, and whether it’s a general repair or an emergency fix. Minor repairs can start around $150–$400, while major repairs may exceed $1,500.
Roof leak repair cost generally ranges from $300 to $800, depending on the size and location of the leak, the materials required, and labor intensity. Complex leaks involving structural repairs or interior damage will cost more.
Flat roof repair cost for commercial properties usually ranges from $500 to $3,000, depending on the roofing material (TPO, EPDM, PVC), the extent of the damage, and roof accessibility.
Mobile home roof replacement cost typically ranges from $3,000 to $8,000, making it generally more affordable than traditional home roof replacements, due to smaller size and simpler structure.
It's not necessary to stay home during roof replacement. Roofing work is noisy and can cause vibrations inside the house, which might be uncomfortable. Most homeowners choose to leave during major parts of the project, but our team ensures safety and keeps you updated, whether you're home or not.
The timeline for a roof replacement typically ranges from one to three days, depending on the size and complexity of the roof, weather conditions, and material type. Larger or more intricate roofs may take a bit longer, but we always aim for efficient, timely completion.
To hire a roofing contractor, start by researching local companies with good reviews and proper licensing. Request quotes from multiple contractors, verify their insurance and certifications, and ask for references. Always ensure you get a written contract that outlines the scope of work, timeline, and payment terms.
Check if a roofing company is legit by verifying their business license, insurance, and local certifications. Look for memberships in professional associations, read customer reviews, and ask for recent project references. A legitimate company will be transparent and provide all documentation upon request.
When choosing a roofing company, consider their experience, customer reviews, warranty offerings, and quality of materials. Make sure they provide clear communication, detailed estimates, and a solid portfolio of completed projects. Local expertise is also a major advantage for understanding regional roofing needs.
Warning signs that your roofing contractor might be ripping you off include vague contracts, pressure to pay large upfront deposits, lack of proper documentation, and unexplained price increases. Always ask for itemized estimates and written guarantees, and avoid contractors who avoid answering your questions directly.
