"The Project Manager was excellent in working around the holidays, December 2025 rainstorms and crew availability to repair my November 2025 roof leak and interior wall damage however, two issues of concern were not resolved, i.e., despite the contract stating that "Painting all vents to match the roof", a vent was not painted because they claimed that referred only to any "new" vents installed, and there are 1/2"-1" gaps between some of the reinstalled tiles. Both issues were emailed to the company and discussed with the Project Manager but not resolved. "

FAQs for natural slate roofing repair projects in Guasti, CA

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.
