"I have requested couple of different quotes to replace the roof on my garage. I decided to go with Infinity Exteriors. Logan Rezash worked with me who gave me the best deal. He was very professional and easy to talk to and explained in full details what they will provide me with my project. The materials and the warranty on the project that works for my budget. They kept me informed of the status of the project from the start to the finish. Their team that worked on the job was very polite and fast. They did an excellent job. They cleaned the yard and twice doubled checked for any loose nails around the garage. If you have a project to be done, I would recommend Infinity for your project. Dragica Miladinovic"

"While removing the old roof, the aluminum coverings on our mansard roof dormers were damaged. The roofing crew attempted to repair the damage but the result was not satisfactory. As compensation they deducted a small amount from the total bill."

Now Joe and his professional crew have replaced all our windows . There are never surprises or additions from when the job is quoted. Once again we are totally satisfied and delighted with their work!! It has been a stress free experience each and every time."

Roofing questions, answered by experts

The amount of hail damage that warrants a roof replacement depends on the size of the hail. In many cases, a roof replacement is needed if your roof gets hail that is 1 inch or larger in diameter. You may also need to replace a roof due to hail damage if you notice several dents in the shingles or there are seven to 10 hail impact marks within a 10x10 foot area on your roof.

Metal roofs have a bad reputation for being loud, even if that's not necessarily true—it's usually only thin tin or sheet metal roofs that are loud during storms. Stone coating adds a layer to the metal that severely cuts down on any noise from rain. In many ways, stone-coated steel roofs are quieter than your average, run-of-the-mill asphalt shingle roof.

You should tarp a roof whenever roof damage occurs. Missing shingles and holes in your roof can cause roof leaks and problems that come with them. Tarping is a quick way to provide temporary roof protection while you wait for a professional roofer to make repairs.

Yes, moss can be dangerous for your roof if left in place to grow without treatment. The moss soaks up and holds moisture. Having a constantly damp roof could lead to problems with rot for the parts of the roof that consist of wood. Additionally, a patch of thick moss may draw insects and birds, which could damage the roof. Thick moss could block the roof’s drainage system. Water then may back up after a rainstorm and cause further damage that could eventually lead to roof repair expenses or the cost of roof replacement.

An improperly installed skylight could potentially impact your roof's warranty. This happens because roofing penetration is necessary during skylight installation. Check your warranty information to verify. In most cases, having skylights professionally installed with proof that flashing is being done to specifications can be enough to preserve your roof's warranty.
