"I had a great experience working with Guardian Roofing Systems. From start to finish, they were professional, prompt, and thorough. The team showed up on time and completed the job within the timeframe they promised, which I really appreciated. What stood out most was how clearly they explained every step of the process—from the initial inspection to the final cleanup. They took the time to answer my questions and made sure I understood what work was being done and why. Overall, I’m very satisfied with the quality of their work and the level of service I received. I wouldn’t hesitate to recommend them to anyone in need of flat roofing services."

"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."

"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

You’re going to need a permit for nearly every roof-raising project. This is a very important step, as the work you’re doing has serious safety considerations. Professionals are the ones to handle this type of work—including sourcing the permits—as they have the expertise required to perform the work safely. Insurance and warranty are usually voided if you do this work without a permit, and you may even be required to halt construction and tear it down as a penalty for working without a building permit.

Properly installed chimney flashing can last anywhere from 15 to 50 years. However, flashing generally only needs to be replaced when it is damaged, corroded, or no longer creates a watertight seal. Several factors influence its longevity, including the material type, quality of installation, and local climate. For example, copper flashing tends to last longer than galvanized steel. Large storms and extreme weather can also damage flashing, potentially requiring earlier replacement. To ensure its longevity, it is recommended to have your chimney and roof inspected annually. A professional can assess the flashing's condition and recommend any necessary repairs.

The material and frequency of maintenance are the biggest factors for determining the longevity of your shingles, not the color. For instance, luxury asphalt shingles can last 30 years or even longer, while slate tiles have an impressive lifespan ranging from 75 to 100 years. That said, lighter-colored shingles can help reduce your energy costs in the summertime.

The best roof replacement type depends on your budget and your particular climate, as well as your personal aesthetic. But in general, asphalt shingles are the best roof replacement type for homeowners looking for durability at a budget-friendly price. Asphalt shingles are the most common roofing material—cost-effective, easy to install, lightweight, and the perfect choice for handy homeowners.

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.
