"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

If your home doesn't have gutters, you can still hang Christmas lights on the roof using specialized clips. Use roof clips designed to attach to shingles or fascia. For tile roofs or the edges of the rooftop, consider using parrot clips. Adhesive light-hanging clips are also a great option. It's important to avoid using nails or staples, as they can damage your roofing material. For unique or complex installations, it's best to consult a professional Christmas light installer to find the safest and most effective solution for your home.

Copper roof strips can last for 20 to 30 years or more if properly installed—in many cases, they may outlast your roof. Inspect your roof annually to ensure copper roof strips remain properly adhered and undamaged, and repair any loose or lifted strips. With very little upkeep, copper roof strips can protect your roof for decades to come.

Gable vents are more common in older homes built before the 1970s. Homes built after this era use ridge vents or soffits, but you can sometimes find homes with both gable and ridge vents. Gable vents can have a purely aesthetic purpose, while ridge vents hide in the roof shingles so air can flow under the roof while keeping the attic dry.

The golden ratio for roof pitch is 1:1.62. It’s simply a standard aspect ratio that home and building designers and architects use when deciding how steep a roof should be to maintain visual appeal. The golden ratio can apply to any home or structure with a visible roof that isn't considered a flat roof.

No, there’s no specific building code that requires a roof overhang. However, installing your roof with the standard 2-inch overhang is good practice, as it helps direct runoff away from your fascia boards and roof decking and into your gutters. Some overhang is especially important in areas that see heavy rainfall and snowfall, as the risk of water getting under the roofing material and causing water damage is much higher.
