"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."

"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"

"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."

Roofing questions, answered by experts

As with any roofing material, there are benefits and drawbacks to consider before installing roll roofing. On the plus side, roll roofing is budget-friendly, lightweight, and comparatively easy to install. It is also ideal for low-sloped roofs and lasts around 10 years. The cons of roll roofing, however, include its low durability compared to roofing materials, restricted color choices, and low ROI.

Pros:

  • Low-cost

  • Lightweight

  • Cut to size

  • Easy and quick installation 

  • Designed for low-sloped roofs

  • Waterproofs your roof for an average of 10 years

  • Easy to purchase and transport

Cons:

  • Less durable than asphalt shingles

  • More prone to cracks and tears

  • Short life span

  • Not as many color or style choices

  • Not as aesthetically pleasing as shingles, wood, or clay tiles

  • Not preferred for a higher home resale value

Roof sheathing can buckle from moisture damage, too much weight from roofing materials, or too much space in between rafters without thicker sheathing to compensate for the added distance. Bucking roof sheathing is a serious problem that can lead to a collapsed roof, so have a qualified roofer near you come to identify the problem as soon as possible. 

Yes, gable vents can let water in. That being said, this usually only occurs during extreme conditions like heavy rainfall. You can prevent water from entering through gable vents by adding a screen that traps the water before it can enter.

Yes, all roofs can benefit from flashing. Roof flashing can protect a property from water damage, roof leaks, mold, and other serious issues. It’s vital if you’d like to extend the lifespan of your roof and avoid costly repairs down the road.

Yes, removing a chimney is a difficult and major undertaking. Chimneys often provide structural support to a home, so if it's a load-bearing structure, you'll need to take extra precautions to maintain your home's integrity. A project of this complexity typically requires a structural engineer, a masonry contractor, and a demolition crew. The removal process may involve taking the chimney out brick by brick from inside the walls. The cost for chimney removal can range from $2,000 to $10,000, depending on the job's complexity. Due to the difficulty and cost, some homeowners opt to remove the fireplace and seal the chimney at the top and bottom, sometimes also removing the visible exterior portion at the roofline.
