Its not often that sit down to wright a review, however good service and quality craftsmanship shouldn't be kept a secret.

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.

Washington Sequia responded within 2 days to start work on my roof. It was soon discovered that the damage was enormous because of carpenter ants. They promptly removed everything and started to rebuild the entire roof. It was completed that week and the problem was resolved. Very efficient and kept me informed. All of the debris was cleaned up and removed. Raul and his crew were absolutely wonderful. Excellent workmanship.

Raul and team did a great job on our new roof! They took two days to finish the roof, then came back a few days later to finish the gutters within a few hours. They also cleaned up very well afterwards.

Our roof was leaking a few month before which was why we originally called Sequoia Roofing. Raul was really quick to respond and come take a look to explain the likely cause of issue. They repaired the fixtures responsible for the leak and also alerted us about mold and condition of our roof. We got a second opinion afterwards that also confirmed their original diagnostic which was why we went through with getting a new roof.

There was also no change in original estimate pricing and what we ended up paying for their services. The second opinion also came with a quote and their prices were good in comparison.

Thanks again to Raul and team for their wonderful work!

Raul and his team did an excellent job on replacing my roof, as well as facia, gutters, painting, chimney & roof repair. They worked over the holidays, and completed everything as described and agreed to. Raul is an honest business operator, and really, we were so happy with how it all turned out.
Would recommend, as well as hire again
Thanks

I hired Washington Sequoia Roofing to replace the roofing, gutters and rebuild and reroof the carport on my house.
From the date I signed the contract, the work started 2 days later. I was so impressed that the roofing crew was here every morning at 8 AM and often stayed until after dark. They were hard workers that never wasted a minute! All work including roofing, rebuilding and roofing the carport and installation of gutters was completed in 5 1/2 days and I could not be happier with the finished product.
The company owner, Raul stopped by often to make sure I was happy with the workers and the way things were coming together!
Great company that provides a well done job in a timely manner!

When Raul came to my mother's house and entered the doorway, he noticed we always take off our shoes and he immediately removed his. Right off the bat, here was a guy who cares about his potential customers. He wrote up an estimate and then went over it step by step ensuring my 96 year old mother of each process to reroof her home. Once she was satisfied, Raul's team started almost immediately. The color of the shingles was decided and the product was ordered. All new roof vents, new gutters and downspouts, flashing in the valleys and a new glass skylight rounded out the job. Raul's team did an impeccable job of cleanup. He was patient with mom's curiosity at every turn. Thank you Raul for a great experience.

Raul is very helpful and informative on helping us get what we needed for a new roof. You can contact Raul very easily and he is very open to answer any questions you may have during the process. He was willing to work with us, getting multiple needs checked of on our roof. We did a whole re-roof w/ added plywood underneath. Raul and his team got everything completed very quickly, communicated every step of the way; even when there was a certain delay due to supplier mix-up. If you want a quality roof, give Raul and his team a call.

A great experience - start to finish with Wash. Sequoia Roofing. Very reasonably priced, prompt service & knowledgeable, professional workmanship. They took care to not damage landscape beds & cleanup at completion was thorough. Raul, owner of W S R, made a couple, ‘no pressure’, recommendations & we’re very glad we followed them. W S R also roofed our carport several years ago which we have been very happy with - that’s why we came back to them. Having some construction background myself, I can say Raul, WSR, is honest, does what he say he will do, doesn’t cut corners and has great pricing! We give Wash. Sequoia Roofing 5 outta 5 in our book - we would recommend WSR to anyone.

I wish I could give more than 5 stars. This team was amazing. A great price, for an exceptional job. I did not know much about roofs, so I had a lot of questions and Raul and his team not only answered the questions but took the time really inform me about what they were doing and what the pro’s and the con’s were with each option we looked at. The whole job was completed in two days. The roof looks great, and his crew did an amazing job of protecting my plants when they took the old room off and then cleaning up all of the various debris afterwords.

Raul and his team did a full garage roof replacement for me after a tree fell on it. He was able to provide me multiple estimates based on different degrees of repair. Once I had decided which way I wanted to proceed, he and his team completed the job incredibly fast! They were priced fairly and his communication was fantastic throughout. Would highly recommend and look forward to working with him on the next project.

Raul at Washington Sequoia Roofing is amazing! I had two large firms come out and do repairs on the roof of my restaurant and paid a lot of money and it kept leaking. Raul came out, assessed and repaired it professionally once and for all. He refused to bill me until after we had a few downpours to make sure I don’t see leaks and it’s fixed. And no more leaks! He did such a great job, kept me informed and he’s a really nice guy. Don’t waste your time with any other roofer!!!

We Answer Frequently Asked Questions
Pricing questions
1. What is the average roof replacement cost for a residential home?

3. What factors affect the overall roof repair cost?
+-

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.

4. What is the typical roof leak repair cost, and how is it calculated?
+-

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.

Service questions
1. Should I stay home during roof replacement?

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.

3. How to hire a roofing contractor?
+-

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.

4. How to check if a roofing company is legit?
+-

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.

5. How to choose a roofing company?
+-

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.

6. How do you know if your roofing contractor is ripping you off?
+-

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.
