"Don contacted me within a day of my initial inquiry and voice mail. He explained to me over the phone what he thought the problem was with my leaky roof and then gave me an estimate. He came the very next day and fixed my roof within a few hours. He explained everything he was doing, kept me updated throughout the project and provided me with a thorough run down of the work he did, the expected remaining life of my roof, and other general roof and shingle related information. His rates were very reasonable and he did not try to convince me that I needed an entire new roof - in fact, he assured me that I could get another 10 years out of it and thus was making the right decision with this repair."

Established in 1976, All Under One Roof has the experience and expertise to get the job done right the first time. Our skilled professionals use only the finest tools and materials for your residential or commercial project. We guarantee our work and your satisfaction.

"Overall it went great. John was down quickly after I first contacted him. He came out in person to give me information and confirm the online measurements. Between meeting him, reading the reviews online, and the impeccable warranty I felt very comfortable choosing him (the price was in the middle of the other quotes I got). The whole process took 3 real long days. Obviously it is loud and disruptive while they are working... but you only need a new roof once. I would suggest not parking in your driveway as there are a lot of people and trucks. At the end they cleaned up very nicely. They are a legit roofing company so they pull permits. Overall I am quite please for the job, cost, time etc."

FAQs for natural slate roofing repair projects in Merrimack, 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.
