"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."

"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."

"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."

"Because I needed only a repair after a tree limb damaged the roof, many roofers either would not bid or I would have to wait for any repair. Universal did the repairs over several days by sending over crews after they had finished a prior job. Worked out well."

"Excellent service and quality work; Tore off an old 40-year roof and replaced and repaired plywood/fascia; installed new torch down roof. Oscar's crew showed up ready to work and got the job done before the rain started. Cleaned up and removed old tv cable wiring and left everything in top shape. Charged a fair price, and provided a very professional job! Highly recommend this company."

FAQs for natural slate roofing repair projects in Rancho Cucamonga, 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.
