"I was very pleased with O'Brien Brother's Contracting for a recent roof repair due to a leak. Eddie came the day that I contacted him. He was the fourth estimate that I received and proved to be very knowledgeable about the matter, including that the GAF shingle color that I have is no longer produced. That said, he was able to make some phone calls while standing on my roof and located a place with some remaining supply of the color shingle that is on my roof. The repair was quick and looks terrific. I will hire him again the next time I need a roof repair. Eddie also removed an old satellite dish and stump of an old electrical connection, and the roof looks great."

"AAA Home Construction responded quickly to my request for roof repair job, visited my home and provided a very fair estimate within hours. Nick arrived on time for the job and made a thorough assessment of the damage within an hour. There was far more damage than anticipated. Unbeknownst to me, there was also has no insulation in the roof. I was given a very fair price to have all the rotted wood replaced and install insulation. Every roofing detail was covered and a new gutter provided. They cleaned up well and even spackled a few areas in the ceiling below (removal of decades old, rotted wood was brutal) affected by vibrations. The AAA Home Construction team demonstrated great integrity and quality workmanship. I've obtained estimates for a couple of other projects, too, and look forward to working with AAA Home Construction again!"

"Kadri and his team were exceptional! My house, built in the 50s, had a roof leak in a section of the roof that was flat. The roof had been replaced about 15 years ago. ABC recommended changing the shingles with a peel & stick rubber roof for the flatter part of our roof. They explained why, with pictures of my and other roofs. They told us that the underlying plywood was in good shape and didn't need to be replaced, but explained why we had a leak. They didn't try to upsell me, just genuinely told me what needed to be done, and did it in a way that built trust. Why 5 stars?: First, their estimate came in lower than another company I also sourced from Angi. Secondly, they were very responsive to my messages. Third, they scheduled their work around my availability and showed up early and finished on time. Finally, they did high-quality, timely, and thorough work. I'd rehire them in a minute. In fact, we are considering having them fix siding and install leaf filters for our gutters."

"I hired Sav-A-Roof to replace my over 3400 sq ft roof and replace 4 skylights. The Owner , Tom, came to give a quote. After meeting him and going over details about roof replacement, I hired them without getting other quotes. The day of the work the crew of a dozen workers came. The crew worked like a well oiled machine! Everyone knew their job and went about it professionally. They finished in 1 day!! 1 really hot July day. The crew moved patio furniture and put everything back right where it was. They cleaned up like they were never there. I would highly recommend Sav-a-Roof and I have already. A couple of neighbors came by to say how hard the crew worked and what nice a job they did. If you need a roof or to replace a roof do yourself a favor and hire Sav-A-Roof, you will not regret it."

Roofing questions, answered by experts

Whether you should choose a flat roof or a sloped roof depends on your particular situation. Flat roofs tend to be less expensive to install. However, sloped roofs have longer lifespans and stand up better to heavy snow and other inclement weather.

Keep in mind that even a flat roof needs to have a slight slope, usually around 1/2 inch for every foot. If it is completely flat, water will pool and cause damage, either from weight or leakage or rot.

Gaps between tiles are necessary to help with weatherproofing, allow for thermal expansion, and increase wind resistance. In general, a small gap no larger than 3 millimeters wide will encourage proper drainage and limit cracking. Beyond that, tiles should overlap a minimum of 3 inches, except at the eaves where they should extend to the center of the gutter.

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.

You’re going to need a permit for nearly every roof-raising project. This is a very important step, as the work you’re doing has serious safety considerations. Professionals are the ones to handle this type of work—including sourcing the permits—as they have the expertise required to perform the work safely. Insurance and warranty are usually voided if you do this work without a permit, and you may even be required to halt construction and tear it down as a penalty for working without a building permit.

While you can technically install TPO roofing over an existing roof, it isn't always wise to do so. The more layers of material you add to your roof, the more weight it must support. You may also develop moisture issues by covering your existing roof with TPO. Your local building codes and regulations may actually require you to remove the existing roof before adding TPO, so check with your local municipality.
