"I highly recommend A&GJ Construction. I called the company to fix a leaking roof. The owner, Arian answered right away and arrived at my home the same day. My 30 year old roof needed repairs to the chimney, flashing and roof tiles. Arian showed me pictures of the damage and returned the next day to make repairs. Arian did an excellent job repairing the damage and showed me pictures of the finished product. You can tell he takes pride in his work which is rare these days and his prices are fair. Arian also called me to follow up after a heavy rain storm to make sure I had no leaks. If you need repairs to your roof, Arian is your guy."

"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 West Nyack, 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.
