"This is the second time we use Richard and his team at Federal Building & Roofing, and they have been excellent. This time, due to the many homes with roof damage from the heavy winds/rain, it took a bit longer to schedule, but he got it done on a Saturday, and right in time before more rain. Professional, Good Quality Work and Dependable."

"Highly recommended! Adam Tweedy and his team repaired our 'cool roof' and three patio decks in just two days. The crew was efficient, careful with our furniture, and the installation was impressive. The roof passed the water test, proving its quality. An added bonus: they didn’t need to remove our solar panels, saving us time and money. For a reliable, water-tight roof at a reasonable price, call Reign Roofing!"

"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."

"David from Clearview Roofing was fantastic in helping replace the roof at my daycare center. We had a huge leak, and he was incredibly speedy with the repairs. He took care of everything from A to Z, making the whole process smooth and stress-free. Highly recommend!"

"Eric came out for the estimate and provided the various options and what he would generally provide. He was patient (Unlike Skyline Roofing)in our vacillation between concrete tile and composition shingles (Provided samples for both types)and also a delay in schedule due to tenting for termites. His price estimate was in line with other estimates (Except iRoof which was almost twice as much as everyone else) He provided a complete package without me asking, including radiant barrier sheathing, roof vents, new flashings, replacement of dry rot wood (included in the overall price) etc. There was a delay in the start date due to rain (Rain in SoCal?) The first day his crew (very friendly) showed up early and did not waste any time tearing off the 40 year old concrete tile roof. Second day they completed the tear off, did some structural repairs I had asked for and started sheathing (required due to the original spaced sheathing construction) Third day (Friday)completed sheathing, building department inspection (permit etc all handled by Eric) and began installation of the felts and composition shingles. They returned on Monday to complete the roof and clean up, with final building department inspection on Tuesday. Very pleased with the final product and the clean up that the crew did. We are now ready for El Nino!"

"Brad from Lifetime Roofing was great to work with . They came onetime and removed and installed a flat roof and a shingle roof. They had to come back out to fix a couple of things with the flat roof and flashing. Throughout the process Brad and Vito managed the project well and communicated regularly. I would recommend them."

Roofing questions, answered by experts

Roofers don’t typically replace vent pipes themselves, but they do handle the flashing and seals around vent pipes when working on a roof. During a roof replacement or repair, roofers inspect the vent pipe flashing for damage, replace deteriorated seals, and ensure the pipe is properly integrated into the roofing system to prevent leaks. If the vent pipe itself is cracked or damaged, a plumber is usually required to replace it, while the roofer ensures the roofing components around the pipe remain watertight.

If you need to replace the roof over your attached garage, a roofing contractor can perform what is called a partial roof replacement that only affects garage roofing. However, it's important to keep in mind that only replacing a portion of your roof creates a situation where your roofing has two different lifespans. You will also miss out on the opportunity for a full roof warranty. In some cases, having two different roofs on your home could increase risks for leaks. When replacing the roof on a detached garage, homeowners have the option to make the project bigger by upgrading their home roof alongside their garage roof. However, this isn't necessary if your home has a newer, properly functioning roof. It is better to try to match the new garage roof to your home's existing roof instead.

While you technically can add a roof over shakes or shingles, it’s not a good idea. Roofing over existing roofing creates a moisture barrier underneath the new roof and since the trapped material is wood, you can expect a moisture problem. While you could get away with installing a new roof over asphalt or steel, wooden roofs should be removed, new underlayment installed, and the new roof installed over that. Also, the extra weight would add strain to your roof structure.

More and more insurance companies are writing torch down applications out of their liability insurance for contractors. If torch down is covered, they generally require a worker to stay on site for two hours after the last flame is extinguished.

For this reason, cold application modified bitumen—also known as “peel and stick”—is becoming more popular, and torch down is decreasing in popularity. Modified bitumen is taking its place, as it uses both hot and cold applications.

The most common slope, or roof pitch, for a shed is 4:12 or four inches of height for every horizontal foot. For areas that experience heavy snow loads, a steeper roof of 6:12 or 9:12 is best.
