How to judge roofing work
A roof is the one system that protects every other part of a building, which is why the way a contractor inspects matters more than the brochure. A thorough look covers flashing, penetrations, valleys and decking — not just the field of shingles — because that is where water actually finds its way in.
Roof lifespan depends more on installation quality and attic ventilation than on the material alone. Poor ventilation cooks shingles from underneath, and incorrect nailing patterns void many manufacturer warranties. The useful questions to ask any roofer are about process and sequence, not only price.
| Material | Typical lifespan | Notes |
|---|---|---|
| Asphalt shingle | 15–30 years | Most common; ventilation strongly affects service life |
| Metal | 40–70 years | Standing seam generally outlasts exposed-fastener panels |
| Clay or concrete tile | 50–100 years | Underlayment usually needs renewal sooner than the tile |
| Slate | 75–150 years | Weight requires adequate framing capacity |
| Single-ply membrane (flat) | 20–30 years | Seams and terminations are the usual failure points |
What customers say
We lost our house in a wildfire and I vowed that our house would be more prepared for future fire issues. I went looking for something I didn't know existed. And then we found CeDur. Polyurethane shingles molded from cedar shingles. We have them on our roof now, and even though the rest of the house is a worksite, we have LOTS of people drop by asking about those shingles. Contractors for other rebuilds in the area come by asking about those. Our kitchen designer said, "I don't care what you paid for them, they are worth it." One neighbor walking by said, "could your house get any cuter?" We love it. I reached out to CeDur 2 months after the fire and stayed in touch with Jason for probably 10 months until we were ready to order the materials. Jason was mellow and knowledgeable. I had many questions over those 10 months. He was a great guy to work with. Now our roof is not only gorgeous, but I will sleep better knowing an ember isn't going to start a fire on our roof. Great product. Great team. HIGHLY recommended.

As a professional in the roofing industry, I've had the opportunity to work closely with homeowners, contractors, manufacturers, and roofing systems of all kinds. While each product brings something different to the table, CeDUR stands out as one of the most thoughtfully designed and impressive roofing solutions I've encountered. Our team at RK Roofing & Construction Inc. recently completed a CeDUR synthetic shake installation on a custom home in Alamo, California, and the finished result is nothing short of stunning. The product captures the beauty, depth, and character of natural cedar shake while offering the durability, fire resistance, and low-maintenance benefits that today's homeowners (and insurance carriers) are increasingly seeking. From the installation team's perspective, the quality and consistency of the materials are truly exceptional. The attention to detail in the product design is evident throughout the installation process, allowing our team to deliver a finished roof that both we and the homeowner are incredibly proud of. The thought and engineering that have gone into this product deserve special recognition as well. The shakes are lightweight, durable, and develop their intended color beautifully after weathering. Their substantial thickness and profile create the rich, dimensional appearance that homeowners expect from a premium shake roof while avoiding many of the maintenance concerns associated with natural wood. It's elegant, it's luxurious, and it's built to perform. When you're selecting a product responsible for protecting an entire building envelope, those qualities matter—and CeDUR delivers on all fronts. Equally important was the support we received from Jason and the entire CeDUR team throughout the project. They were responsive, knowledgeable, and genuinely invested in helping ensure the project's success. Having that level of partnership from a manufacturer makes a meaningful difference—from the initial sales process through final installation in the field. It's not everyday that a roofing product leaves a lasting impression, but this one certainly does. I would confidently recommend CeDUR to homeowners, architects, HOAs, and fellow roofing professionals seeking a premium roofing solution that combines exceptional aesthetics with long-term performance. And if you're fortunate enough to have a contractor who takes as much pride in the installation as CeDUR takes in manufacturing the product, you're in for something truly special. We're already looking forward to the next CeDUR project. Based on our experience, homeowners who choose this system can expect a finished roof that not only protects their investment, but elevates the entire property for decades to come. For those considering a synthetic shake roof, CeDUR has set a standard that few products can match. After seeing the finished result firsthand, it's easy to understand why.

As a real estate agent, I’ve seen my fair share of concerns come up during a transaction but the level of service I experienced here was truly exceptional. My clients were understandably concerned about the condition of their roof during the purchase of their home, so I reached out to customer service and connected with Jason. From the very beginning, he took our concerns seriously and acted immediately. Not only did he listen, but he also escalated the matter by looping in the CEO, Konrad Bolowich, assuring me they would thoroughly look into it. What happened next was beyond anything I expected within minutes, Jason personally connected me with Konrad, who happened to be in the Bay Area at the time. Despite being about 1.5 hours away, Konrad went out of his way to come meet us at the property in person. He took the time to inspect the roof, reassured my clients that it was in excellent condition, and right there on the spot with his computer he reissued a 50-year warranty to give my clients complete peace of mind. This level of responsiveness, professionalism, and genuine care is incredibly rare. It made a lasting impression not only on me, but most importantly on my clients, who felt confident and supported throughout the process. I will absolutely be recommending them to all of my clients moving forward as they explore roofing options. Truly outstanding service.
