"This company was great. They got back to us right away for an estimate and a start date. We had to postpone a week due to rain but Richard contacted us in a timely manner to let us know when the new start date would be. The crew came on time, were very nice, did the work quickly and professionally and cleaned everything up. Richard came by every day to check on it all. We are very pleased with our new roof, patio cover and the whole process."

"They were kind and efficient. I had to be diligent and push them to do a water test of the roof or else they would have diagnosed it with the wrong issue. But other than that, they were able to perform the work and solve the issue. It ended up needing a flashing maintenance rather than to re-do a whole portion of my roof (big difference... $1,500 vs. $4,500)"

Roofing FAQs, answered by experts

Though roof coatings can last up to two decades, it’s a good idea to recoat your roof every four to six years. This is especially important if you have a built-up roof, which is vulnerable to moisture issues. Inspect your built-up roofs annually to make sure they don’t need a new coat.

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.

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.

Roofing jobs can be expensive due to the required materials and the dangerous nature of the labor. The cost to repair a roof ranges from $390 to $1,920, with an average cost of $1,150, depending on what kind of roof you have and any accessibility concerns. Replacing a roof is much more expensive at $5,890 to $12,800.

If a roof is not vented, trapped air and moisture have nowhere to go and will cause moisture to build up in the attic. When moisture builds up, it can cause mold and mildew, leaks, and rot. It will make the space hot and stuffy, which can result in higher energy bills as the HVAC system works overtime to regulate the temperature.
