"John came in today on a holiday day to check my roof. He is a very honest man. He told me my roof is still good for another two years, and doesn’t need any repairs at this time. I highly recommend him for any roofing projects. Thank you John!"

"Tar Star Roofing (Anthony) responded in one day, inspected my roof and provided a quote the next day. The crew started work a couple days later, very professional, experienced and courteous. They completed the job on time and to my complete satisfaction. Communications from Anthony were constant, including recommendations on additional repairs as damage was found, photo documentation and expert advice. I highly recommend Tar Star Roofing for any roofing needs."

"The crew at James & Whitney co were extremely friendly, courteous and went out of their way to make sure that we were happy with our new roof. The job was done fast and is of wonderful quality. Beyond that, this is a company that truly stands behind their work, as they have reached out to me several times in the past few months to ask how the roof is holding up. I truly couldn’t recommend James & Whitney highly enough to anyone who needs work done on their roof."

"He arrived and knew what was to be repaired . It was replacing chingels on the roof . When he arrived he looked up and saw exactly the location of where the shingles came from . He's very knowledgeable! He went right to work . And was finished in no time . He did check other areas of the roof for me , thus was on the front main part of the house . I did question him that my husband had told me were going to have to have another roof done in the very near future . I had discussed this with crieg and he said no you don't. Your roof is in good condition right now , and you've still got some years to go here before that is to be done . It was a big relief to me to hear this . This man is very knowledgeable with his line of work , and I trust his judgment. I highly recommend him to anyone . Very friendly to talk with ."

"We had Power do our Roof and Gutters on our 120 year old home. This is our first big project on our new house and Power made the experience great. Their were a couple of hiccups but Power was able to rectify the situations. The project was supposed to be a 2 day project, but when taking the old shingles off they noticed the roof decking needed to be repaired because of significant wood rot. They finished the total project in 4 days. Power met every expectation. One part of the process that was a little frustrating was that I didn’t have one point person to talk to if I had questions. I had multiple project managers but I did get all my questions answered when I called. We would definitely recommend them to anyone."

"I HIGHLY recommend Pro Warrior! I've hired them for many jobs already as they are responsive, affordable, and proactive. I had them replace my roof and siding - I am obsessed with the results to say the least. I hired them back to complete a finished basement. Pro Warrior is the absolute best around."

"My wife and I had storm damage to our roof, skylight, and front shutters. I contacted several roofers to discuss the repairs and had few people actually call me back. When I contacted Cedar Valley Exteriors, I spoke to David Faraone pretty quickly and he was incredibly helpful and was able to walk me through the entire process to get my roof replaced and all the repairs completed and covered by my homeowners insurance. Very helpful."

"They did a great job repairing my mom's roof from a tree falling on it. They also resealed her cracked asphalt driveway the same day and they did a great job on that too! Their prices were reasonable. I would recommend them to a friend."

FAQs for natural slate roofing repair projects in Portsmouth, 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.
