"I had Boss Roofing go to my rental properties outside of Ft Myers to check the tile roofing to see if it might have been damaged from Hurricane Irma. They were quick to check out, access and repair. I would highly recommend them for repairs or replacement."

"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."

"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"

"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

Chimney crowns are located above the final brick layer at the top of a chimney. It’s important to get regular chimney maintenance and inspection, because it is near impossible to spot chimney crown damage without getting on your roof.

Thatched roofs last for between 30 and 50 years in most cases, which is longer than most asphalt roofs. However, getting that life span from your thatched roof requires more maintenance than you’d need for most other materials, including fireproofing, brushing, cleaning, and rethatching as the material gets worn down. You’ll also need routine inspections to ensure you’re not at risk of leaks.

The best way to prevent wind damage to your roof, especially if you live in an area prone to hurricanes, tropical storms, or tornadoes, is to invest in a roofing product with high wind resistance. Look for the ASTM D3161 and ASTM D7158 ratings to see the specific wind speeds your roofing product can withstand. Impact-resistant shingles have the highest wind resistance ratings and will give you the best chance of avoiding wind damage.

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.  

Yes, roofers can repair and replace roof trusses. In fact, because trusses are such an important part of your roof’s structure, it’s best to have a roofing contractor deal with a damaged truss. If you try to fix the problem without the right skills or knowledge, your roof could sustain further damage or even collapse.
