"Total waste of $3000. Job looked like it was done by toddlers. Again. I asked them to fix the botched original attempt. Didn't expect much, they met my expectations. "

"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."

"It went extremely well: team was courteous, professional and efficient. Cleaned up at the end of each day, paid attention to the property and delivered excellent results. New roof looks stunning, and this one is hopefully not leaking, unlike the 30-year old roof they replaced!"

"After completing the work the company checked out the roof for me for any future damage. They got the job done but I thought it was pricy for two hours of work. They did good. It went fine, the price was just high."

"Start to finish the entire roof replacement was about 2 days, which is impressive with how great it looks. Now some people might think that it’s expected for the roof to look really good because it’s brand new but I drive around neighborhoods all the time and I see brand new roofs that don’t look great…We added in some vents for the attic (with their suggestion), which I really didn’t think would make such a big difference, but I gotta tell you they have. The temperature difference inside my home has been noticeably different. overall, I can’t imagine going anywhere else in the future for any issues we may have and I will definitely be referring them to all my friends and family."

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.
