"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."

"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."

"After 28 years in a newly built home, a few weeks ago I noticed a leak in the roof following California storms. Out of all the roofing companies I contacted in panic, Rafael from Titanium Roofing was the first one to show up with a drone. He gave me comprehensive report with pictures and a competitive pricing. His team promptly patched multiple leaks, replaced a few tiles and even cleaned up the gutters. Then he came back with another crew to paint the inside of a high ceiling, all with a big smile. I therefore recommend him and his company without hesitation for any roofing jobs."

Customers say: Super punctual

"I had two jobs done by modern method on my rental property. one in 2016 and one in 2019. One was a skylight leak repair and the other a section of leaking flat roof. both jobs took a couple months to mobilize in winter. The skylight repair failed after 3 years. The other section was done with white material, while the rest of my roof is brown, so it looks pretty terrible. As the owner, I was never made aware of this decision- they worked directly with my property manager which I consider unprofessional considering they changed my roof color. I called them out to see what can be done about both. They told me the skylight repair was not done the right way and needed to replace the entire roof section including the skylights. They also said they would torch down some brown material over the white material they provided and quoted me for both. I tried to appeal to them as to why I would give them even more money to do my skylights when they recommended the repair that failed, and also why in the world they would change my roof color. The estimator gave me some options including torching brown material down over the white, paying full price for all of the repair. I called to complain, and they sent their owner over who basically told me that any flat roofing is always done with white material (sorry, not true), that torching brown material over the top is not a very good thing to do, and that the skylights obviously need to be replaced. He didn't have anything to say about why I should trust them to do good work other than "I wasn't involved in the conversations, so I don't know". Very disappointed."

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