"They installed solar panels as per contract. They were on time and removed all material when done. I had roof damage from a storm and they repaired it at no extra cost. So far I am happy with this company and plan on using them again for house repair.

"Fernando, his son Frankie, and Jeb Kraft (substituting for a vacationing crew member) were excellent. Their experience, work ethic, and attitude were outstanding. Every issue that arose as they repaired work another company did several years ago was solved by Fernando. He always provided several options and we selected the best one for the situation. Because Fernando hand-dug the needed holes and trenches he had no problem when he encountered the main electric line several feet from where 811 had marked it."

"All work was done in a timely, professional manner.  Shingles and majority of the work was done within two days with a few items finished a few weeks later-a skylight that had to be ordered, etc.
Everyone did a top notch job.  The roofers even went over the grounds two times picking up nails after the job was done, and did a very good job at that.  They were very pleasant folks.  We were glad to have them do the work.
After the ridge vents were installed, I noticed s savings in my electric bill, too.  We wee able to raise our thermostat by 3 degrees and still stayed cool in the last few hot days of summer.  Ridge vents are definitely the way to go.
Thank you, Tony and crew.  Keep up the good work.  I highly recommend Tony's Roofing Service.
The office staff even helped me get my warranty registered with the Certainteed company after the work had been completed.

FAQs for natural slate roofing repair projects in Portland, TX

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.
