"Contracted Federal Building and Roofing with Richard and his team after Listening to Richard's suggestions during the estimate. Had bad water damage to many Rafter Tails as well as a severe leak in the garage, Had several Contractors out for estimates some wanting to go a much more expensive route to repair the damaged wood on the Rafters as well as suggesting a complete Torch down on the entire roof which was not needed, which came with a less than desirable Warranty along with higher costs. Richard gave me peace of mind with his knowledge and suggestions which in turn provided a much longer Warranty and cheaper more effective route to repairing the damaged Rafter tails,all at a very reasonable price compared to other estimates. Any Contractor should have been able to provide me with these suggestions and alternatives but failed to do so. Richard and his team were Professional, polite,cleaned up thoroughly each and every day and completed the job on time as scheduled."

"David from Clearview Roofing was fantastic in helping replace the roof at my daycare center. We had a huge leak, and he was incredibly speedy with the repairs. He took care of everything from A to Z, making the whole process smooth and stress-free. Highly recommend!"

"I contacted Hoyt for a quote. Charles came out and made a thorough presentation, leaving me with a pamphlet explaining the product to be used. Within a day I received an email with a quote that was comparable (even a little more attractive) than the other half-dozen quotes I had received. I checked references and reviews, and decided to hire them to replace my 20+ year old roof. I was advised that the final cost could be more depending on how much wood repair was needed. I was also advised that the cost was higher due to the cost of wood (pandemic). I needed a start date delayed due to my schedule, which was to the company's advantage. They began exactly when I needed them. Charles even assisted in moving the RV out of the driveway. Demo of the roof was complete in one day. The rest of the work was done efficiently, and crew cleaned up each day leaving the house looking neat. Inspection was easily completed, and work completed in approximately one week, with Charles answering phone calls with questions and assisting as needed. I would highly recommend Hoyt for product, cost, and quality of workmanship."

"We have a historic home and there was additional care required to replace siding beneath the roofing material at the eaves. The team at Jordan roof completed the entire job in only 4 days, they fixed up our dormer which had shingles that had deteriorated, and repainted some of the shingles. Our home looks better than ever! Great responsiveness, fair pricing, and high quality work."

"We called Robert Noy Roofing for a leak we had. Everyone wanted to the-roof our house. After Robert checked out the roof, he gave us photos and explained why we didn?t need a new roof. We thought we were going to have to pay out about 20,000.00 but after Robert did the repair he saved us literally thousands of dollars. He also water tested the area to make sure it didn?t leak. He was the only one who came out and was completely up front and very knowledgeable, really impressive. Thank you Robert!!!!!!!"

"Corey was able to come and resolve our issue in a timely manner. Best way to communicate is through a phone call. Leave a message if it's not answered and they will get back to you as soon as they can. Had a leak in my roof that kept springing up. He had someone come look at it the same day, and they're able to patch it up just before the rain. I'm grateful for the quick resolution."

FAQs for natural slate roofing repair projects in Ontario, 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.
