It Won't Rot, Curl, or Split
Real cedar reacts to Northern Illinois freeze-thaw cycles. DaVinci's pure virgin resin construction does not. There is no warping, splitting, or moisture damage to manage year over year.

The product
Why Homeowners Choose DaVinci Over Real Cedar
DaVinci tiles are modeled from actual hand-split shake, so the texture and shadow lines are real. What is different is everything that happens after the install.
The Color You Pick Is the Color You Keep
DaVinci tiles are fortified with UV stabilizers and hold their color through decades of sun exposure. Real cedar fades and silvers within a few years.
Class A Fire Rating Without Treatments
Real cedar requires fire-retardant treatments that wear off and need reapplication. DaVinci is Class A out of the box and stays that way for the life of the roof.
Insurance Companies Like It More
Many Illinois and Wisconsin carriers are dropping cedar coverage entirely. A Class A, Class 4 composite roof often qualifies for premium reductions and keeps your home insurable long-term.
Side by side
DaVinci vs. Real Cedar Shake
DaVinci Roofscapes
Hand-split shake texture, deep grooves, and non-repeating grain patterns engineered for decades of beauty. No annual treatments, no surprise replacement costs, no calls when storms roll through.
Real Cedar Shake
Beautiful when it is new, and steadily losing ground from day one. Old-growth cedar is gone, so today's shakes split and curl faster than they used to. Insurance carriers are tightening or dropping coverage entirely.

What Homeowners Are Saying
"We needed to replace our 23 year old shake roof. Jorge was attentive and responsive with color selection. He not only answered all my questions regarding the details of the job, but even checked both attic spaces before and after the roof install to ensure everything would be ventilated properly. Pretty cool to see my new roof from a drone angle above!"

"It was time to replace the roof on our 2-story, 5000 sq.ft. house. CJM Roofing was outstanding to work with. They saw where one section of gutter splashed on to our cedar siding and added a splash guard. Having dealt with dozens of contractors over the years, I can safely say that CJM Roofing was one of the very few that met and exceeded my expectations."

"I have a flat French Mansard roof, which is unique and never had gutters. Matt quickly emailed me a quote and scheduled the work within days. His crew over delivered on all my requests in 1 DAY! I am so happy. CJM is the best choice for roofing and gutters because the quality of the materials and services equally are excellent and the price is right."
