"We are giving Hoyt Roofing a 5 Star rating, because of the excellent job they did on the installation of our new roof. The whole process only took four days and the workers went over and above to keep us informed of the progress and maintaining a clean work area. We were impressed from the initial meeting where we discussed and deciding on the terms and conditions to completion of the job. They were not pushy or try to upsell their products. We highly recommend this company to anyone who needs a new roof."

"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!"

"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."

"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!"

"I recieved an amazing roof inspection from Clear View Roofing. Project manager Erik came by and guided me through everything with details and step by step. He helped give me a certification on the details regarding my roof on the spot. Big thank you for an easy process with Clear View."

"I never thought I'd describe a roof replacement as a pleasant experience, but here we are. From the start, Jonathan and the team at Roofing Angels were a breath of fresh air. We got multiple quotes, and Roofing Angels wasn’t the cheapest, but they were the most transparent and professional. Jonathan took the time to inspect our roof thoroughly (unlike others who barely looked at it) and explained why certain materials were better than others. I appreciated that he wasn’t just trying to upsell us—he genuinely wanted us to make the best choice for our home. The crew was incredible. They arrived early, worked efficiently, and kept us updated throughout the process. I loved how respectful they were of our space—our driveway and yard were spotless when they finished, which I can’t say for other contractors we’ve worked with in the past. Now, our house looks better than ever, and I actually feel relieved every time it rains, knowing our roof is rock solid. If you want a team that truly cares about their work, look no further than Roofing Angels!"

"I had an awesome experience with Green Ladder Roofing. They repaired a few leaks on my roof and later did a full replacement when it was time. The crew showed up right on schedule, worked efficiently, and cleaned everything up afterward. You wouldn’t even know they were there except for how great the roof looks now. The customer service was great, we had an amazing experience with the team."

Roofing questions, answered by experts

The lifespan of asphalt shingles is typically between 15 and 30 years, depending on the type of shingle and other factors. Standard 3-tab shingles have the shortest lifespan, around 10 to 15 years. Architectural shingles last longer, averaging 20 to 25 years. Luxury or designer asphalt shingles are the most durable, with a lifespan of 40 years or more. Climate, installation quality, and regular maintenance also play a significant role in how long your shingles will last. Signs that they need replacement include granule loss, bald spots, and roof leaks.

No, you can’t use your home’s square footage. You have to calculate your roof’s square footage, and then you may have to convert your square footage measurement to correspond with how the roofing material is measured. For instance, some roofing is sold in “squares,” which equals the total square footage of the roof divided by 100. Shingles are sold in bundles that may not correspond to the number of squares you need. Metal roofing is sold as sheets, so determine the amount of square feet each panel will cover and then divide the total square footage by the coverage area.

Yes, thatched roofs are legal in most areas in the U.S., but you should always check your local building codes to ensure there are no restrictions in your particular area before installing one. Even where they are legal, you’ll usually need to apply fireproofing to the roof to keep it up to code. Keep in mind that a new roof might not increase home value as much if you choose a thatched roof, as they aren’t common in the U.S. and might not be as desirable to many home buyers.

Gable vents are more common in older homes built before the 1970s. Homes built after this era use ridge vents or soffits, but you can sometimes find homes with both gable and ridge vents. Gable vents can have a purely aesthetic purpose, while ridge vents hide in the roof shingles so air can flow under the roof while keeping the attic dry.

Most Cape Cod houses are two stories tall at the peak, although they’re considered one-and-a-half stories tall because the steep roof pitch cuts off a portion of the living space on the second story. Unless you raise the roof on your Cape Cod house to add a dormer, the interior rooms upstairs will lose some usable living space to the sloped ceilings.
