"Very nice, polite and efficient. After inspecting the roof and chimney flashing Tony told me my roof was actually very well done and in good shape, and that in his opinion the source for water leaking into my home was due to a rusted out chimney case cover and termination cap (I got those items replaced as suggested and my problem was solved). I had actually called two companies to get an analysis and quotes to fix the problem. The other company told that my relatively new roof should be ripped up and replaced in that area of the roof. I appreciate the professional and honest approach of Great Western and they will be who I will use in the future when it does come time to replace or repair my roof."

"I dealt with Leon De Anda for my roof work. Leon was honest and professional and very informative about what could be done with my roof. He offered me a few options and also asked me if there were anything specific I wanted done. I basically described what I wanted and he curtailed his bid to what I was looking for at the best price. I liked the fact that he was honest and straight forward without playing any games or try and screw me over. In the end, I decided to get a whole new roof, down to even getting all new plywood. The men who came to work on the roof were competent and professional. They went to great lengths to only bother me when it was necessary. Everyday they made a mess but at the end of the day they would always clean it up. I thought they were very professional. Leon was not at my house everyday but he was always just a phone call away. He was very accessible. Once the work was completed, Leon and myself walked around the property and inspected the work. He made sure that I was completed satisfied before everything was finalized. Protecta Roofing made a big impression on me based on the way they started and completed this job. I would highly recommend them to anyone looking to get some roof work done or even some general contracting work done."

"Zenith was easy to work with and they did great work. I received three different quotes to remove and install new gutters around my house. Zenith was the only company that was able to provide an estimate without physically visiting the property, their rates were better than the other estimates I received, and they completed the work on time and within the budget. I would use Zenith for any future roofing needs and highly recommend them to others."

"To start, the requirement to strictly adhere to all manufacturers' specifications and building codes for this re-roofing job was stringent, for I monitored the crew's work from start to finish. Tear-Off: After two weeks delay, the actual work started with SW Roof TearOff removing the old shingles. A little bump here, as there were a lot of old nails sticking out of the roof deck, pieces of tar paper still stuck to the deck, a cracked fascia board (which they quickly blamed the old wood) and a broken vent pipe after they're done. Bad wood replacement: Decent work by Excalibur Roofing crew, but definitely no precision carpentry, because of the crew did not possess precision equipment. Roof shingles installation: New underlayment / peel-n-stick installation was acceptable, again under my supervision. Some sections of the Drip-edge installation had to be re-worked. I had to request careful staging of the shingle rows, as the crew did not initially take into account the out-of-square characteristics of each roof section. The nailing of shingles was just acceptable, as I had the crew remove quite a few nails that were either shot-crooked or too deep into the shingle; in this respect, the crew, although experienced, was rushing the shingle-nailing job with less than perfect nail guns. The installed vents were about 0.75 in. off the pre-cut holes in the plywood; again, something that could have been prevented with a little extra time and care. The trimming of shingles along the rakes was sloppy; the 0.25 in. shingle overhang was in itself a challenge, and yet, the crew had to resort to scissors because of dull cutting blades! The same thing happened to the trimming of the shingles along the valley lines. The crew was very cooperative, but Erik never showed up during any stage of the installation (I guess he was counting on me to take his place). In the end, the finished roof looks pretty good from far away and has been watertight for two years; the actual price paid to Excalibur Roofing Services, Inc was somewhat high, when taking into account the time I had to spend checking each stage of the project. December 2018 Update: I discovered that a Decoridge cap came loose at the eave’s end of the hip ridge, hanging with just one nail (the other nail was shot-crooked and never penetrated the plywood). I then called Excalibur Roofing Services, Inc to request warranty service, only to be told by Mike that the company is currently out-of-business. It does look like this company’s 10-year workmanship warranty for my roof is down the drain; so, I ended up re-nailing the loose cap and seal it myself."

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