"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."

Roofing questions, answered by experts

The size of the dumpster will determine how many squares of shingles can fit in a dumpster. You can place between 4 to 20 squares of shingles in most standard containers.

Roof leaks develop quickly and can cause serious damage to your house and in extreme cases, quite nearly ruin it. Roof leaks have been known to affect even the foundations of a home, so taking care of any issues as soon as they pop up—or even before—is of the utmost importance.

Skipping the installation of a drip edge or gutter apron can lead to significant water damage. Without this component, water is more likely to seep under roofing materials or leak behind gutters, damaging the fascia, soffits, siding, and even the interior of your home, such as the attic. Over time, this moisture can cause rot, mold, and deterioration. In colder climates, a missing drip edge also increases the risk of ice dams, which can lead to expensive repairs. A drip edge is an essential part of a roof's drainage system, and some local building codes may even require its installation to protect the home from water damage.

Look for certified local roofing contractors with plenty of experience working with cedar. There are also several important roofing questions to ask before choosing a roofer, including whether they are licensed, bonded, and insured. Once you’ve rounded up a few good candidates, compare estimates and hire whoever gives you the best bang for your buck.

When it comes to choosing the best roof color for a blue exterior, you have plenty of options. For a classic neutral look, go with a light gray, dark gray, or black roof. Blend gray tones if you want a more eye-catching look for your roof, or go for a different splash of color with a green or even red. Take inspiration from your neighbors if you want your house to fit in on the block.
