"I had 3 layers of roofing on my house, and over the last 2 years I spent a ton of money on repairs. Finally I called Rapid Roofing and when they assessed the roof, they let me know that the reason I was having so many leaks was from the 3 layers of roofing and not having a proper roofing system. I decided to do a full roof replacement and it was the best decision I could have made because my roof looks great, my electric bill went down, and now I don?t need to keep repairing it! Awesome communication, great people and I got a great price! Bravo Rapid Roofing!"

"My entire roof was redone in one day!. Four seasons staff are true professionals, they had a crew of 20 people working from 7:00 am till about 5:00 p.m. They arrived fully equipped and worked until roof was completed. The following day the Gutters were installed and voila!, my roof was completed and my yard was cleaned as if nothing happened. Professional service. Very happy with the service provided by Four Seasons."

"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."

"I would highly recommend them. They fixed a leaking roof for me. They were available quickly for an estimate and to do the work. The price they gave was more than reasonable especially compared to other estimates. They work fast but accurate. Took pictures as they went along to show me. Clean up was perfect. Can't forget to mention the customer service was beyond great."

Roofing FAQs, answered by experts

You can install a spray foam roof over shingles, but it may compromise the roof’s protective qualities or shorten its lifespan. Before installing a new roof, ask a qualified roofer if your existing roof needs to be removed before installing a spray foam roof so you ensure your home has quality, long-lasting protection. 

A solar roof can replace an existing roof. Solar panels fit on top of traditional roofs. In contrast, solar roofs that contain photovoltaic (PV) materials, like solar shingles and solar tiles, are standalone roofing systems installed as a main roof. In some cases, installers can place them on existing roofs and as part of new construction. Carefully assess and choose the right type of solar roof replacement for your home and needs.

You may become so frustrated with the look of moss on your roof that you contemplate whether to clean or replace your roof. Fortunately, you don’t have to go as far as replacing it. After cleaning the moss, you can use a chemical solution to keep it away. For further protection, trim branches that overhang the roof, as fallen seed pods and leaves on the roof allow moisture to collect, encouraging moss growth. Consider adding zinc-coated flashing to the roof, too. As rain washes across the zinc, it leaves zinc particles behind that inhibit moss growth.

Properly installed chimney flashing can last anywhere from 15 to 50 years. However, flashing generally only needs to be replaced when it is damaged, corroded, or no longer creates a watertight seal. Several factors influence its longevity, including the material type, quality of installation, and local climate. For example, copper flashing tends to last longer than galvanized steel. Large storms and extreme weather can also damage flashing, potentially requiring earlier replacement. To ensure its longevity, it is recommended to have your chimney and roof inspected annually. A professional can assess the flashing's condition and recommend any necessary repairs.

Underlayment exists under your tile roof. It helps protect your home by acting as a secondary water barrier. Often, when roof tiles fall off, underlayment that's in good condition can temporarily keep water from getting into the home. However, immediate replacement of missing tiles is crucial to avoid additional roof damage.
