"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."

"We have once again reached out to Joe Kim at J & K Home Improvements when we had a new project planned. We were completely satisfied when we replaced our siding and roof with Joe. 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

Mansard roofs are still popular in Paris, where they originated, and throughout France. In the United States, you can find mansard roofs on some older buildings in Manhattan. The architecture also appears on some Victorian and Colonial-style homes. There are pockets of homes with mansard roofs in New York City and Los Angeles, where they were once more popular than they are today.

Most manufacturers’ warranties do not cover wind damage to roof shingles, but some companies include a wind warranty rider in their warranty offer. You can purchase this rider to protect yourself, your wallet, and your roof from any damage that might occur from wind. Be sure to read all the fine print and understand any limitations of the warranty.

Yes, replacing a roof is always a good investment if the current one is in poor condition. Not only will it preserve the structural integrity of the home, but it can also add value at the time of sale. The average return on investment for a new roof is between 48% and 61%. Prospective buyers are also more likely to purchase a home with a recently replaced roof since that means they won’t need to worry about that expense in the near future.

Asphalt shingles blister when air gets trapped between building materials, either within the layers of the shingle itself or in adhesives on the undersides of the shingles. As the roof heats up in direct sunlight, the trapped gas expands and creates a bubble in the roof. Eventually, the bubble can pop, leaving an exposed area of decking and underlayment.

Generally, hailstones that are one inch in diameter or larger can cause significant damage to a roof. However, smaller hail can also cause damage, particularly when accompanied by strong winds, if it strikes an aging or poorly maintained roof, or if hailstorms are frequent in your area. Hail that is ¼ inch (pea-sized) or smaller poses a minimal risk of immediate, permanent damage, but cumulative impacts can cause deterioration over time. The extent of the damage also depends on the roofing material; hail-resistant tiles like slate or certain types of asphalt shingles can withstand impacts better than other materials. If you are concerned about potential damage after a storm, it is always a good idea to have a professional roofer conduct an inspection.
