"Very professional company to work with. Was having leaks over the years after multiple handy man repairs, but those usually dont last especially after the hurricane we just had. When it was time to re-roof, I came across Clear View. Communication was excellent. There was not a single time someone didnt answer my call or call me back ASAP to answer any questions I may have had. Their price was right in line with the other estimates I had received, so it really came down to who can provide me with the most trustworthy work. They were on top of the project from start to finish, and completed the job exactly when they projected. Ive already recommended them to my neighbors and family members, Overall, I would work with them in the future. Definitely"

"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."

"Cohen Roofing exceeded every expectation. Unlike other bidders, Mr. Cohen came to the site himself, explained my leaking-roof options, and offered three price tiers: quick fix, solid repair, or full re-roof. He honestly advised that the cheap fix would cost the most long-term, so I chose the full re-roof. My 70-year-old home's sheathing was in bad shape — replacement far exceeded the 10% in the contract, yet he charged a very fair price to restore all of it. He obtained the LADBS permit and passed inspection. My roof is tricky (a 1:12 slope is technically a flat roof per CA code), so his team installed 2-ply torch-down throughout, covered every transition, and added extra-wide flashing at the vents — exactly where my old leak was — finished in white Polyfresko. He was responsive, flexible, and sent photos of every stage. At the end I received all contracts, original warranties, and permits. A knowledgeable contractor you can truly trust. I recommend Cohen Roofing without hesitation."

"My boyfriend and I are both art nerds, so we wanted huge windows and natural light to give us inspiration when we begin our drawings. I called Reliable Roofing for some skylight installation and two large picture windows in my kitchen and bedroom. I couldn’t even believe I was in my own house when they finished, it looked incredible! The nature in front of our house looked so enhanced and fresh looking through the new windows, and I can’t wait to make new creations with the help of Reliable Roofing!"

"I contracted Preferred Roofing on the recommendation of my HVAC company. I wanted an established company that did their single job expertly; i wanted a company that was valued by other professionals. It's just fact: i will only get the roof replaced once on my house, which is not enough interaction to establish a relationship with a vendor--I needed to rely on an existing relationship. Preferred Roofing was excellent from the first phone call. David is not merely charming, he is 100% invested in being the best--his easy good nature comes from confidence, and that confidence comes from his team. Everyone at Preferred Roofing is a good & courteous worker. They came by a couple times in advance to check requirements and explain the process. They even handled interactions with the HVAC guys. Everyone was straightforward, all communication was clear & concise. The wait list was a few months, which confirmed my choice: I wanted workers that spent their time working. The crew was like a military unit--organized & efficient, and totally autonomous. I stayed out of their way. It took three days, there were no complications and not even any questions. If they had asked questions, i simply would have told them to do whatever was the best solution--the whole team obviously knew roofs more completely than i can imagine. The crew did a remarkable amount of work, and kept the site so clean it was like they were never there. I often describe work that I cannot do as "priceless." Preferred Roofing not only did work i cannot do, hard & messy work, they did work i didn’t even know existed. Maybe I could nail down a sheet of plywood and lay a tile... but i had not even heard of an O’Hagin Vent, and i can’t possibly explain how to “torch a cricket”. I was glad to find professionals, and happy to pay for their work. My house was immediately more comfortable; honestly, the next week was as hot as summer, my house was easily 15 degrees cooler than pattern. The new roof was worth every dollar. David wrapped the project personally, stopping by to review the job and provide paperwork. The final payment stayed exactly on bid. The whole process was a delight and--hahaha--I hope I never see them again!!"

FAQs for natural slate roofing repair projects in Stevenson Ranch, 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.
