"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

Tile and shingle roofs both have their pros and cons. In general, tile roofs are a larger upfront investment. In some cases, they can cost twice as much as shingles, but they last much longer and generally hold their value better than shingle roofs. Shingle roofs, on the other hand, are budget-friendly and quicker to install.

White is the most energy-efficient color for roofs because solar energy reflects off white surfaces the best. Silver is also a good choice.

Complete house winterization goes above and beyond the list we created above. In addition to everything listed, full house winterization also includes:

  • Performing a home energy audit.

  • Preparing your deck and patio for winter.

  • Learning how to start a snowblower.

  • Replacing smoke detector batteries.

  • Installing outlet gaskets.

  • Installing storm doors.  

No, a metal roof will not make your house hot. In fact, metal roofs help keep your home cooler by reflecting heat instead of absorbing and transmitting it inside. Metal also has high thermal conductivity, which means it gains and loses heat quickly. While the sun may heat the metal, the roof rapidly transfers that heat back into the air rather than retaining it. This reflective property can lead to energy cost savings of up to 40%, as your cooling system won't need to work as hard to maintain a consistent indoor temperature.

Single-ply roofing lasts for between 15 and 30 years, depending on the type you install and the climate in your area. TPO roofing has the shortest lifespan of 15 to 30 years, followed by PVC, which lasts for 20 to 30 years. EPDM roofing is the longest-lasting single-ply roofing option, with a lifespan of 30 to 40 years. Keep in mind that hail, strong winds, blown debris, and foot traffic can all reduce how long your flat roof lasts.
