"Jack checked the roof Friday at 4PM and arranged the job the second day, Saturdayï¼ October 5ï¼ 2024. His guy works on the shingles repair and pipe collar replacement professionally. His guy is so nice and followed my instructions by hummer down pup nails all around then glueing the leaves tightly. His and his team make me happy and confident that the repair will extend the existing roof life. I strongly recommend him and his team! Mark"

"I am most satisfied with my new roof and the workmanship involved with the installation. Top quality Owens Corning shingles coupled with a superior attic ventilation system. Quick response from their installation manager(Mike) to repair a loose downspout and good communication from their management team. I would definitely recommend this company to friends and family."

FAQs for natural slate roofing repair projects in Wilmington, DE

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.
