Branden and Travis worked hard, and the results speak for themselves: the new roof looks fantastic, and the porch has given the property a fresh new life.

Jesse James Roofing & General Contracting is a small company that takes pride in every job regardless the size of the job! We have competitive pricing and quality work. Adding space to your home is one of the best ways to increase the current use and long-term value of your home. Whether you are remodeling or adding, we can help you to maximize the space to your needs and increase its value and appeal.

"I had a terrible experience with Jesse James Roofing. They installed a roof on my house that ended up leaking, and I had to spend months arguing with them to get a repair. Unfortunately, the repairs didn’t work, and the leaks persist. A teenager—presumably Jesse's son—was overseeing the job, and after asking a few basic questions he couldn't answer, and I asked for someone more qualified to manage the work, I was told I was being arrogant. They refused. We’ve been dealing with this issue for over a year, facing ongoing water damage and stress every time it rains, having to place towels to catch the leaks. We’ve requested a refund, but they refuse. I highly recommend avoiding Jesse James Roofing."

FAQs for natural slate roofing repair projects in Londonderry, NH

If more than 30% of your slate roof is damaged, it's time to consider a full replacement. This will prevent further deterioration and avoid costly recurring repairs. A professional slate inspection (costing between $130 and $360) can confirm whether repairs are sufficient or if a full roof replacement is the better option.

A slate roof can last anywhere from 60 to 150 years, depending on factors like installation quality, regular maintenance and repairs, and local weather conditions. Compared to materials like clay and concrete, which often last around 50 years, a well-maintained slate roof offers superior longevity, durability, and long-lasting aesthetic appeal.

Yes, you can use temporary patch solutions, such as roofing cement or patchwork, to provide immediate relief for minor leaks or underlayment issues observed from inside your home. However, these provisional fixes do not replace the need for a permanent, professional exterior repair, which is necessary to ensure the long-term integrity and weather resistance of your slate roof.
