"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 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 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

Whether replacing the entire roof or just installing roof shingle replacements in small areas, always pull up the old roof shingles. While you can technically put new roof shingles (but not other roof materials) over old shingles, this can add weight strain to the roof and prevent the new shingles from securing properly to the roof.

The terms “roof sealant” and “roof coating” are used interchangeably to describe the rubber, silicone, polyurethane, or acrylic product applied to the roof’s surface for waterproofing and UV protection. Products like roof caulk can also be called “roof sealant,” but the term is more commonly used for the protective coating.

The short answer is, yes, cedar shakes do last longer than asphalt shingles. But the long answer is, it depends on maintenance. Asphalt shingles last about 20 years, while cedar shingles typically last about 30 years with proper maintenance. If they are very well maintained and installed in an area with a mild, drier climate, they can last up to 50 years.

The most common slope range for roofs on houses in snowy areas is between 4/12 and 6/12, or 50%. A roof with a slope of less than 10%, or roughly a 2/12 pitch, won’t be effective at shedding snow. However, roofs that are too steep can allow large amounts of snow to build up and fall all at once, creating a hazard for those on the ground.

The golden ratio for roof pitch is 1:1.62. It’s simply a standard aspect ratio that home and building designers and architects use when deciding how steep a roof should be to maintain visual appeal. The golden ratio can apply to any home or structure with a visible roof that isn't considered a flat roof.
