I was looking to replace my shingles roof in Encino and contacted a few roofing companies in the neighborhood. Out of four roofers, Quality Roofing Specialist was the only one that worked with my budget as well as my schedule. Their work was fantastic, and we love the outcome. They exceeded my expectations. I will definitely recommend to friends.
Jose Linareza month ago · GoogleI was recommended this roofing company by a friend, and I’m really glad I went with them. I had a problem with water leaking into my attic from the flashing around the chimney, and the team was very helpful from the start. Tony was the roofer working with me, and he was always professional and friendly. He took care of resealing the flashing and chimney, which made the leak much better right away. He kept in touch with me after the work, and now we’re working on sealing the chimney even more to make sure everything is perfect. I feel confident that the team will get everything fixed up right. Based on my experience so far, I’d definitely give them five stars. Thanks to everyone there for their hard work!

Roofing contractor questions, answered
Straight answers to the questions homeowners ask us most.
Is the roof evaluation free? What is the $199 Roof Check?
Yes, the roof evaluation is free. We use drone footage to see the condition of your roof, explain what we find in plain English and give you a clear next step: repair, monitor, maintain or replace. The $199 Roof Check is optional. It’s a tune-up where we seal the vents, pipes and flashings as much as possible, and if you move forward with a repair or replacement, the $199 is credited toward the job.
Do I have to pay anything up front?
No. The roof evaluation is free, and if you choose the optional $199 Roof Check, there’s no deposit — you pay after the visit.
Do I need a full roof replacement?
Not always. Many roofs just need a targeted repair or a tile lift & relay. The free roof evaluation tells you what your roof actually needs, so you’re not paying for work you don’t need.
Will I know the price before work starts?
Yes. Before any work begins, you get a written scope and price. No pressure, no mystery pricing and no surprises.
How much does a new roof cost?
It depends on the size, pitch and material of your roof, and on what we find under the old one. Our guide to roof replacement cost explains how a price comes together, and the free roof evaluation gives you the exact figure: a written scope and price before any work.
Do you offer financing?
Yes, for home roof replacements: through Momnt Financing or Service Financing you can spread the cost over monthly payments. It doesn’t cover repairs or commercial projects. See roof financing for how it works, and ask us once you have your written scope and price.
What kind of warranty do you offer?
Our installs are backed by a 10-year workmanship warranty (call for details), and the roofing materials carry the manufacturer’s warranty, which depends on the product and its warranty tier. At the final walkthrough we go over your warranty with you in plain English.
Is Quality Roofing Specialists a licensed roofing contractor?
Yes. QRS is a licensed, bonded and insured California roofing contractor: CSLB license #1061942, licensed since January 3, 2020. We work on homes and businesses across our service area.
Do you work with insurance claims?
Yes, as our schedule allows. Our team is small, so we can’t always be there when the adjuster visits, but we’ll help you where we can, and our photos and written scope give you clear documentation to share with your insurance company.
How soon can someone look at my roof?
Call (310) 340-1643 or send the request form on this page, and we’ll set up a time for your free roof evaluation that works for you. If water is coming in right now, call us and see emergency roof repair.
What types of roofs do you work on?
We handle tile, shingle and flat roofing, including roof replacements, roof repairs, tile lift & relay, inspections and ongoing roof care.
What areas do you serve?
We serve homeowners across our service area. Enter your ZIP code in our service area map to check your city, or call (310) 340-1643.
