"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

Roof underlayment usually lasts as long as the roofing material that covers it, as it’s not directly exposed to the elements. In most cases, roofing companies will replace the underlayment each time they install a new roof. In some cases, particularly with slate, clay, or certain metal roofs that can last 50 to 100 years, your underlayment may require replacement within that timeframe, especially if you start to notice roof leaks.

If your home doesn't have gutters, you can still hang Christmas lights on the roof using specialized clips. Use roof clips designed to attach to shingles or fascia. For tile roofs or the edges of the rooftop, consider using parrot clips. Adhesive light-hanging clips are also a great option. It's important to avoid using nails or staples, as they can damage your roofing material. For unique or complex installations, it's best to consult a professional Christmas light installer to find the safest and most effective solution for your home.

If the bay window extends beyond your existing roofline, you must add a roof or a small “skirt” to divert storm water and prevent water damage. The window roof can match your existing house roof, or be finished with copper or other decorative materials. Most bay windows have a roof with complete flashing regardless of their placement to prevent leaks into the home.

Roof leaks develop quickly and can cause serious damage to your house and in extreme cases, quite nearly ruin it. Roof leaks have been known to affect even the foundations of a home, so taking care of any issues as soon as they pop up—or even before—is of the utmost importance.

In most cases, no, roofers won’t need to come inside. Some reasons roofers may need to come inside are to assess ventilation. inspect roof leaks, or check for any structural concerns.
