"All under one roof did a great job. The price was very reasonable and the quality of the work was excellent. in addition to the roof they also installed a a solar tunnel to supply natural sunlight to second floor. All work was completed and all the debris was removed. The work was completed in one day. This is the third roofing job that I have hired them to do and I was very pleased with all of the work."

"It went incredibly well. I woke up one morning to a leak in my roof. I knew the roof was going to need to be replaced at some point, but I was hoping I'd get another year out of it. The roof was in bad shape when I bought the house. I immediately started calling all of the roofing companies I could find on Google. It was early so I was leaving voicemails. Kasey from James and Whitney was the first and only one to get back to me in a timely manner. He was incredibly helpful on the phone, walking me through how to put a tarp over the impacted area. He even swung by later THAT DAY to check and make sure it was installed properly and to assess the roof. I knew it needed to be replaced so we went right into talking about estimates. The estimate was within my budget but the new roof came with a FIFTY-YEAR WARRANTY for parts and labor. You just can't beat that kind of warranty on an asphalt roof. We were scheduled within a week and I had a brand new, perfectly installed roof within a month. Kasey and his team were super respectful during the installation. When the installation had finished, Kasey inspected every inch of my property to pick up any tiny bits of trash and leave our lawn spotless. The whole process was so easy and stress-free. 10/10 would recommend!"

I am extremely happy with the work. My roof looks exceptional! I would recommend David for your roofing repair or replacement. I will be giving a recommendation to friends and family (or strangers if in conversation about roofing needs). Please don't hesitate to call Cedar Vallley and ask for David Faraone."

"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.
