"They kept breaking the tiles on the roof they installed so they had to keep ordering new tiles to complete the job. The problem was they resorted to texting on occasion until they were asked to actually call us to resolve, which is not very professional. Our biggest concern is the solar installation. There were delays because they did not install the correct breaker. Now we found out that some of the panels are facing the wrong way and need to be re-positioned. We are unable to monitor the effectiveness of the system they put in even though they told us we would be able to. They're having trouble getting access to monitoring for us so they can see what is happening with our panels but we can't. They have continually asked for payment although they have not completed the job to our satisfaction. That was the same even when the roof wasn't completed they wanted payment. I would not recommend them to others. They were great at first but their responsiveness has been lacking and the work has continually gotten sloppier. Their demands for the payment have also become more frequent."

"Though the work they did turned out very well, I wouldn't hire them again because of all the difficulties in communicating with them and having them actually arrive to do the work.  First, they pretty much will only communicate via email, except when they are calling you to tell you that you know how they were supposed to be there that day at 8 am?  Yeah, they will be late or need to reschedule.  Several phone messages I left weren't replied to until weeks later, and then via email.   I too prefer using email when I can, but I think a business should return phone calls and make themselves available to speak to customers.
 I can only guess that they were having a really off week, because  they had  a truck (which was supposed to come pick up  all the cabinet doors and take them back to their site to be painted there) break down, delaying the pick up for a day or two, and then one of their compressors also broke down, so I the doors weren't done when they were supposed to be, delaying their return and reinstallation in my kitchen.  In all, the process that they had told me would take 3-5 days took over a week.
Then, after they left, I had to take about an hour to straighten all the cabinet pulls that had been left crooked, and months later I'm still finding their little post-ins and masking tape markers.  Just sloppy stuff.
Everyone I dealt with was very nice and pleasant, and I was ultimately happy with the work they did, but the process was frustrating enough that I can't recommend them.

FAQs for natural slate roofing repair projects in Thornton, 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.
