"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."

"Custom Roofers III, had the lowest bid for our flat roof. We didn't realize they weren't going to take off old roof. Put new materials right over old roof. Not a fan of that decision."

Roofing questions, answered by experts

Tar and gravel roofs last an average of 30 years, which is longer than the average lifespan of many other flat roofs. The gravel on top of the waterproof membrane helps protect the roof from UV damage and physical damage, so if you keep your roof drains clear and carry out annual roof inspections to catch issues early, you could see up to 40 years of useful life from your roof.

Thatched roofs are expensive for two main reasons: high labor costs and low supply of available roofers. The labor is more intensive for a thatched roof than other roof materials, so your contractor will work longer and charge more for the installation. There are also few professionals with the specialized skills and experience to install thatched roofs. Since the supply of available professionals is low, the cost of compensation is high.

Roofing estimates and inspections are not the same thing. Roofing inspections (whether done with a drone or by the traditional method) help you find any damage or defects on a roof. You will pay a set fee for a roofing inspection and use it to get certification or to determine whether repair or replacement is necessary. Beware of unsolicited contractors coming to your home and offering a so-called free roof inspection—these are often scams.

Roofing estimates, on the other hand, are typically free and offered by a roofing company hoping to earn your business. Some roofing estimates are performed with drones, while other companies will still opt to send people up onto the roof. Either way, the estimate is for roof repair or replacement costs the company wants you to hire them for.

Flat roofs are cost-effective, offer usable space, and are easy to maintain. Foam and single-ply materials provide excellent insulation and durability.

Venting a gas water heater out of the roof is preferable in most cases. Heated exhaust gases naturally rise, so a vertical vent pipe is efficient. If you’re trying to vent through a pipe exiting a wall, the angle of the pipe may be more horizontal than vertical, making the venting system less effective. If you go through a wall, you may need to add a fan to ensure a successful expulsion of the gases outdoors.
