"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."

Roofing FAQs, answered by experts

Yes, replacing a roof is always a good investment if the current one is in poor condition. Not only will it preserve the structural integrity of the home, but it can also add value at the time of sale. The average return on investment for a new roof is between 48% and 61%. Prospective buyers are also more likely to purchase a home with a recently replaced roof since that means they won’t need to worry about that expense in the near future.

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.

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.

Verify that your roof is licensed and insured by visiting your state's contractor's licensing association. Most states have a database to double-check your contractor's name and address against the information provided. The contractor should also display both their license and insurance on their website with links to the related agencies.

Yes, a tile roof will increase the value of your home more than an asphalt shingle roof. Not only do tile roofs look nicer and add more to your curb appeal, but buyers will understand that roof tiles last longer than most other materials, so they can expect minimal maintenance and a long roof lifespan after closing, which often means they’ll be willing to pay more for a home with this roof option.
