"Great price, lower than other companies quotes. Doesn't add on work you don't need. They actually fixed my roof the very next day as they were able to move their schedule around to accommodate. Highly recommended."

"Excellent communication from the first meeting to look at the roof, through establishing the contract, scheduling, and completing the work. There was unexpected additional action required at the end of the project and, Rene, the Superintendent, followed up and had that completed ASAP. I also want to comment that the roof replacement was done on my parents' home in S.Calif. I live in the Seattle area. I had hoped to be there during the roof replacement but the timing was such that I could not be. Rene was accessible to me by phone or email if I had questions or was working through details on behalf of my parents. He always responded in a timely manner. Rene also went above and beyond by taking pictures of each stage of the project, emailing them to me with updates. My parents asked me to be on point so much of the communication came to me, yet Rene also kept my parents' updated. Jordan Roofing is professional, timely, and clean up was thorough. Excellent customer service and high quality work. Even the city roof inspector commented that Jordan Roofing Company does excellent work. I highly recommend Jordan Roofing Company."

"I can't recommend Reign Roofing enough! They completed our steep roof project in just one week, and the quality of work is excellent. After receiving quotes from 10 other roofers, Reign Roofing stood out for its professionalism, reasonable pricing, and transparency. Our insurance (USAA) was difficult, offering only half of the replacement cost, but Reign Roofing worked with them to submit a detailed estimate and get our roof fully covered. We’re grateful for their hard work and help navigating the insurance process. Thank you, Reign Roofing!"

"Recently finished my roof replacement with Clear View. Initially had an old shingle roof with a leak in a corner bedroom. Had a very informative and helpful inspection. The entire process was easy and done in a week and couple days. Would recommend to everyone who needs assistance with anything regarding their roof/home. 10/10"

"We needed our old roof replaced and got a few quotes from different roofing companies before we chose California Building Professionals. They were the only ones that explained the roof replacement process, answered all our questions, and made us feel comfortable with the project. GREAT COMPANY!"

"Every person who worked on my roof/solar project was outstanding, professional, courteous, knowledgeable, and dedicated to getting the job done to my satisfaction and on time. This includes the sales rep, the office staff, the roof team and the solar team. They all treated me as if my project was the most important. Given their reviews I'm positive this is the way August Roofing approaches all projects."

"We had a leak in our roof. Another company came out and didn't even try to identify where the leak was coming from. they tried to sell us a new roof. Cabrera went into the attic and identified the leak, then went on the roof and found a nail that had come out. They patch the spot and added tar to some other areas. The first company wanted $67,000 then before he left they came down to $41,000. Cabrera said we had at least 5 years left on our roof and charged us $500."

Roofing questions, answered by experts

The most common roof pitch is 4:12, which means a rise of 4 inches for every 12 inches of horizontal run. However, roof pitch varies widely based on roof design, climate, and even the roofing materials you plan to install. Your building type also plays a role, as flat roofs are common on commercial buildings and some modern homes.

There are several signs that indicate you’ll need new underlayment. Clear signs include missing or damaged roofing and exposing the underlayment to the elements. Additionally, if you notice water damage in your home by the roof after a storm, it could indicate that your underlayment may need to be replaced. If your gutters aren’t draining properly, it could also lead to rotting or water damage to the underlayment.

The exact weight of a bundle of shingles depends on the shingle type, manufacturer, and other factors. It can weigh anywhere between 45 and 800 pounds.

Tipping your roofer or their crew is not customary or expected, but it is always appreciated. It is entirely up to you whether you want to give them extra money for their work. If you feel they have done an exceptional job, a tip can be a nice gesture. As an alternative way to show appreciation, you can provide coffee, breakfast, drinks, or grab-and-go snacks like cookies or doughnuts.

Underlayment is required by building code, so any roof installed without it is technically against code. The underlayment acts as the second layer of defense against water, so installing a roof without underlayment means a much higher risk of roof leaks. You’ll have the best chance of avoiding roof leaks if you install drip edge flashing covered by underlayment, and then install your roofing material over that.
