"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

Ridge vents can last as long as your roof does. As long as your ridge vents were installed correctly by a qualified professional, they will need very little upkeep. Inspecting your ridge vents annually to ensure they aren’t cracked, clogged, or leaking will help prolong their lifespan. 

Yes, roof ridge caps are a necessary part of your roof system. Your roof ridge cap is at the peak of your roof, where two slopes of your roof meet. Roof ridge caps seal the seam and help protect your roof from water and debris, and because they’re pre-bent and thicker, they’re more suited to the job than regular roof shingles, which can break when bent.

During the framing process, builders connect the roof to the walls with materials, including metal connectors, plywood panels, and wood blocks. These roof-to-wall connections are important and provide weatherproofing, noise and temperature insulation, protection against pests, and home integrity. The type of connector and method used will vary, depending on your home’s construction and needs, and each has pros and cons in terms of cost, noise insulation, longevity, and reliability. Talk with your home or roofing contractor about the best connectors for your roof and walls, and what they recommend for your home.

Yes, capped chimneys should still be vented. Failing to vent a chimney will result in condensation buildup inside the chimney, which commonly results in mold growth. If mold begins to grow in a chimney, it frequently goes undetected and spreads quickly through the home. Mold and moisture can damage the structural integrity of your home, and exposure to mold can cause discomfort and illness in residents.

You should plan on waiting as long as it takes for the roof deck to dry out completely if it gets wet. In most cases, this will take about 24 hours, but it could take longer if you have shading on your roof or cloudy weather after the rainfall that prevents the sun from drying the material.
