"Our roof had some longstanding leaks that kept getting worse, and the deck over the roof and over the leaks was in very bad condition. We hired Cali Roofers to dismantle and discard the existing decking boards and to find and fix the leaks. Over two days they did exactly that. They were very professional, listened carefully to our concerns and explained clearly everything they were proposing to do, and carried out the work to a high standard. They were honest and trustworthy, so much so that after our initial consultation with them we didn't bother getting any other quotes. We just had a gut feeling we could rely on them to do a good job."

"They replaced cracked tiles, and replaced the underlayment on leaking area with good rubberized material. Reset a lot of tiles that just moved from the wind. Sealed around all vent pipes. They done more than I expected."

Welcome to Dr. Roof! With over 15 years of experience, we are proudly serving Los Angeles County and the surrounding areas. Here at Dr. Roof, customer satisfaction is our number one priority. We aren't finished until you are happy. Give us a call today for a free consultation. We look forward to working with you. Flexible hours available!

"I was tasked with some repairs on my parents house that had been unoccupied for 16 years. The roof had a leak (with severe drywall damage inside), the gutters had come down in places and there was a termite problem. I met with numerous contractors and exterminators and finally (after advising parents) chose Nikki with Dr Roof for the replacement of the under-layment and broken tile for the Tile roof (house in Stevenson Ranch CA). Nikki is so professional and sent pictures and kept me informed every step of the demolition and replacement process. Since I was at the residence, I didn't even really need that because I watched over much of the work, but still she went "above the call". Then as other projects were needed, she had contacts for extermination, facia replacement and painting, eve trough replacement and interior house work. I went ahead and contacted other contractors and vendors for those services, but in every case Nikki's contacts were better (or at least similarly) priced. And I am glad I went with her suggested repair people - they too were all very professional (and in no way associated with her, she just recommends them as she's been in the business 27 years and knows reputable, quality contractors). And in every case the other people I had on various projects sang Nikki's praises. She also coordinated the timing for all these contractors to do their work (obviously some things like facia have to be replaced and painted before Eve troughs installed, etc.) Dr Roof overall did a great job. They kept the place neat and I thought their underlayment was the best quality of any of the contractors I met with ( and I got other quotes from companies / individuals). There is still more work to do on the yard and in this house (projects for next year after bank account recovers from these projects - ha! ha!) Nikki will be my first call when looking for additional work on this house for my parents."

"The project manager Eddie was amazing! Right from the start he assured me that I would be completely satisfied with my new roof and I am. My family and the neighbors are complimenting me, haha. Eddie made sure every detail of the project was exactly as I requested. I interviewed five roofing companies which was somewhat stressful but once I signed with Eddie at Atom Builders he kept in close contact with me to update me on the work schedule, and there were no problems with the permits or inspections, they took care of everything. Many thanks to Eddie and the team for a job well done!"

Roofing questions, answered by experts

It’s possible for a roofing estimate to change after the initial assessment, but in most cases, it shouldn’t. There’s always the risk that something unexpected will happen that causes prices to go up, like discontinued materials or your roofer discovering previously hidden damage to your decking when ripping off the old roof. However, experienced roofers should account for these circumstances in their initial estimates. Roofing contracts are binding, so always check your contract for language about how and why your numbers could change.

EPDM roofing is a single-ply roofing material made of rubber, and a professional will install it in a single sheet and seal the seams. Built-up roofing (BUR) consists of multiple layers made from asphalt, adhesives, and roofing felt. A professional will construct the layers of BUR on-site. EPDM is easier to repair and has better resistance to extreme temperatures, while BUR is more fire-resistant and affordable.

You can put new shingles over old shingles, but most municipalities only allow for two layers of shingles before you have to rip off the old roof and start fresh. In some areas, only a single layer of shingles is allowed due to the weight a bundle of shingles adds to your structure. In most cases, it’s a good idea to remove your old shingles before you install new shingles, especially if you suspect that a roof leak may have compromised the decking underneath.

Here are a few tips on how to choose a roofer:

  • Get everything in writing

  • Ask for insurance, license, and bond, then verify them

  • Check their reviews 

  • Ask for recommendations

  • Get multiple quotes

You’ll also want to watch out for any red flags like:

  • Pushy sales tactics

  • Not willing to show necessary documentation

  • Bad gut instincts

While you can stay at home during a roof replacement, you probably won’t want to, as it’ll be very noisy. The area around your home will also be messy, as roofers will be discarding old roof material and storing their equipment on the ground.
