"My wife and I realized we needed to replace a portion of our roof , a spanish tile. We contacted NewHaus roofing and construction company and were warmly greeted by Joseph one of their representatives. He helped us negotiate a great price along with the advice from his supervisor Gregory. We chose a beautiful terra cotta replacement and the work was diligently completed in two days thanks to the craftsmanship of Pedro and his crew. We are thankful for Joseph who was with us through our project from start to finish. We would recommend this company to anyone considering a roof replacement."

"I was really pleased with the new roof job Lifetime Roofing and Renovation performed for my mom's house that I decided to hire them again for my house. Tony the project manager and his crew once again knocked it out of the park. The work done efficiently and and with quality/care. My wife and I are very pleased with how the project came out. The price point for concrete tiles is what I expected given the rising costs of material and labor."

"We had Imperia Roofing & Exteriors handle the wood siding on our place and it came out really nice, way better than we expected honestly. The guys were straightforward, worked hard, and didn’t cut corners, you can tell they actually care about the finish. Everything lines up clean, trim looks good, and the house just looks newer now. They kept us in the loop, answered questions, and the job didn’t feel chaotic like some projects do. A few small things came up like any job but they handled it quick and kept moving. Overall we’re happy we went with them and would use them again for sure."

"Needed to have our roof replaced. Lifetime Roofing is great! Gui from Lifetime stopped by the same day I called in for an estimate, and he was able to get us a very competitive price. Gui regualrly checked in to provide us updates on the status (permitting, install progress, etc.) and to see if we had any questions or issues. The crew was fantastic. Clean and quick. The best part? The City of Mt. View told Lifetime to install 20 vents on a 2,500 square foot roof!!! Lifetime spent time with the inspector and got that down to 5 vents and ridge vents. Very helpful! Overall, a wonderful experience."

FAQs for natural slate roofing installation and replacement projects in Portola Valley, 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.
