"Sequoia Roofing did an excellent job from start to finish. Once again it is proven to me "you get what you pay for". I got multiple estimates. Sequoia was not the least expensive. Mike Rochholz answered all my questions before, during and after. Communication was clear. Helped me choose the replacement tile. I knew what was going to be done and when I was on their work calendar six weeks ahead. Started on Monday and finished on Friday. Attention to details and professionalism of crew earn high praise, too."

"We had a leak around the chimney area of our roof. Rick initially diagnosed the leak as from old flashing in need of replacing. Was quoted $1250 for the repair. They had their guys come out promptly and replace the flashing all around the base of the chimney where it meets the roof. Doing a nice clean job. However, upon the next rain event that we had (about 1 week later), the leak was still vey apparent. Rick came back out to look at it again, and realized that he had mis-diagnosed the problem, and that the leak was actually coming from another area where the fascia board on the side of the roof penetrates the chimney stack. He was very apologetic and reduced the amount that I owed him for the repair by 50%. He then referred me to a stucco contractor to correct the actual problem. He was very honest, and I appreciate his being willing to work with us. To be honest the flashing probably needed to be replaced anyway in my 30 year old house."

"Initially we called Protecta Roofing to get our roof inspected. Even though we currently did not have leak issues we thought it wise to have the roof inspected as the ceramic tiles were close to 30 years old. Mario was prompt in responding and coming out to inspect. We were informed of 10 broken tiles. Our decision was to have the tiles replaced and power wash the roof to remove algae which included applying an organic sealant product. After a couple weeks of failed attempts to obtain an estimate from Mario I was in touch with Edith, the company sales manager. From then on the communication and process went smoothly. Edith and crew were a delight to work with. Her knowledge of the work to be done and concern for my satisfaction were impressive. In addition to repairing the broken tiles, our solar panels were cleaned along with painting the pipe flashings. Because everything looked so clean we decided to have Protecta power wash our driveway and side walkways, which are also cleaned with the organic algae solution. The work done was outstanding!"

"After having investigated five companies bidding on my roofing project, there was one clear choice, Cal Roof. The bid was made without delay and was the most professional and complete of any I had encountered. Doug had obviously done his homework and came prepared to our first meeting. After discussing what I was looking for, I received excellent documentation indicating the full scope of work being provided, and full disclosure in writing of the warranty and materials used. There was no long winded sales presentation or up-sell. Everything was very straight forward and transparent. The thoroughness of his proposal was impressive, and he gave me a very competitive price. I was pleased with our communications from our first meeting until the day we wrapped things up. I have no hesitation in giving a full recommendation of Cal Roof."

"We had 5 or 6 contractors come out over a 2 year period, that gave us quotes ranging from $900 to $7000. When we finally made a decision on a company (Protecta Roofing, estimate $1500), they didn't show up on the scheduled day, then called me a week later (when it was raining) and asked if they could come out that day to do the work. We immediately hired a 2nd company (SRS Roofing, estimate $1900), who called me the day after they were scheduled to do the work, and told me that the quote was too low and that they would send me a new quote, but never did. I was ready to give up on Angie's List all together because the contractors seem so flaky. When we got Zenith out to do a quote, I was very pleased with Bryan's knowledge, explanations, timeline and quote ($1100). He got to work a couple days later (in between rain), he cleaned the roof and sealed it, and provided us with a 2 year warranty. I highly recommend Zenith for a no bull, well done job."

"I was looking for a roofing team to re-roof my 2000 sq-ft ranch-style home. The roof is composition shingle. I did my due diligence, researching roofing companies/contractors in the San Diego area and obtaining seven (7) quotes. C&I came back as the low bidder - which, honestly, made me a little nervous at first. But I did my research and they seemed like a solid company - having been a staple in Spring Valley for decades and having good customer reviews as well as an A+ rating with BBB. In addition, they were using the same or superior materials to all the other guys. I hired them and was very glad I did. This company is awesome - from top to bottom. The work team they sent out was stellar - timely, efficient and focused on their job. They were also very friendly and put-up with all my questions. They did all the fascia and rafter-tail repairs/replacement along with the re-roof. Fantastic job all-around. Do yourself a favor and at least get a quote from these guys."

FAQs for natural slate roofing installation and replacement projects in El Cajon, CA

A slate roof features thin tiles of natural stone installed over a solid deck and underlayment. Formed under intense heat and pressure, slate is exceptionally durable and delivers a distinctive, high-end look. Because the material weighs far more than asphalt, most homes need added structural support before installation. 

While upfront costs are higher and routine inspections are a must, many homeowners choose slate for its unmatched longevity and curb appeal.

Slate stands out for its 50- to 200-year life span, low maintenance, and classic aesthetic. It’s fire-resistant, energy-efficient, and often boosts resale value. 

On the flip side, slate runs far more per square foot than asphalt, weighs up to four times as much, and demands a contractor who specializes in the material. Tiles can crack on impact, and repairs cost more because the work is slow and precise. If your budget and structure can handle it, slate delivers top-tier performance for generations.

Natural and synthetic slate aim for a premium, stone-like appearance, whereas asphalt focuses on affordability. Real slate runs $10 to $30 per square foot installed and lasts up to 200 years; synthetic slate costs $10 to $15 and tops out at 50 to 100 years. 

Standard asphalt averages $3 to $8 per square foot and needs replacement every 20 to 30 years. If you want the slate look without the full price tag—or extra roof weight—synthetic is a solid middle ground.

With routine inspections and prompt repairs, a natural slate roof can last well beyond 100 years; some hard-slate installations reach the 200-year mark. Soft slate falls in the 50- to 125-year range, and synthetic products last 50 to 100 years. 

Remember, flashing, fasteners, and the underlying structure may need attention sooner than the stone itself. Severe hail or fallen limbs can also shorten life span, so schedule periodic checkups with a slate-qualified roofer.

If you plan to stay in your home long term—or want a standout selling point—slate delivers strong value. Although installation costs are high, owners often recoup 60% to 70% at resale and enjoy lower replacement cycles than asphalt. The stone’s durability, energy efficiency, and timeless curb appeal also appeal to eco-conscious buyers because fewer roofs end up in landfills. Just be sure your framing can handle the weight and that you budget for occasional specialty repairs.

Skip the DIY climb if you have a slate roof. Slate may be tough against the weather, but a single misplaced step can crack a tile and create a leak path. The surface also turns slick when wet, upping the risk of injury. Professional crews use staging and hook ladders that spread weight across multiple slates, protecting both the roof and the worker. To inspect or repair slate, call a roofer who specializes in the material.
