"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."

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

Costs depend on material, labor, and additional features like underlayment or insulation.

There’s no single best roofing material for flat roofs, but EPDM is considered an excellent option because it lasts longer than TPO roofing and built-up roofing, and it’s the most adaptive to extreme temperatures and variations in temperature. EPDM can also be highly energy-efficient at both ends of the climate spectrum, with black EPDM helping to reduce heating bills and white EPDM helping to keep your building cool in extreme summer temperatures.

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.

The amount of hail damage that warrants a roof replacement depends on the size of the hail. In many cases, a roof replacement is needed if your roof gets hail that is 1 inch or larger in diameter. You may also need to replace a roof due to hail damage if you notice several dents in the shingles or there are seven to 10 hail impact marks within a 10x10 foot area on your roof.

The type of roof and roofing materials that are best for your mobile home depends primarily on its shape and slope. Rubber materials, such as EPDM and TPO, are best for flat, low-sloped, or bowed mobile home roofs. Asphalt shingles or metal roofing are best for mobile homes with sloped rooflines.
