"Arian repaired my old slate roof; replaced damaged slates, installed copper flashing along the ridge lines. Has not rained yet, but I trust he will stand behind his work. Price was fair. he arrived on schedule, and completed work in one day. Most importantly, Arian is more than a roofer; he is an artisan with a feel for slate."

"It went well. They did a great job. We had a leak on the roof between the sky light and they did an excellent job at sealing it. They came back and resealed it so they sealed it twice. They did a great job and we have not had any leaks. I would use them in the future."

"Nelson and his crew worked incredibly hard for a full day, removing moss from my roof and repairing shingles that had blown off during a. wind storm. They were on time, worked consistently from 9:00-5:00, cleaned up after they were done, and left my roof in absolutely beautiful condition. I could not be more pleased. This was a big expense for me but one that was totally worth the money."

FAQs for natural slate roofing repair projects in Valley Cottage, NY

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.
