Cedar Shake vs DaVinci Synthetic Slate on a Glencoe Home: Which Holds Up Better in North Shore Weather — A 30-Year Roofer's Honest Comparison
Cedar shake vs DaVinci synthetic slate on a Glencoe home — what holds up better in North Shore weather, and what we'd actually specify.
Why this comparison comes up on Glencoe homes
Glencoe sits on the lakefront between Winnetka and Highland Park, with architectural character that runs heavily toward Tudor Revival, Colonial Revival, French Eclectic, and Prairie-influenced custom homes from the 1910s through the 1940s — plus a meaningful base of substantial new construction. The roofs on these homes were originally specified as cedar shake or natural slate in most cases. When it's time to re-roof, the homeowner is almost always weighing whether to stay in true cedar or natural slate, or to move to a premium synthetic alternative. DaVinci Roofscapes — based in Lenexa, Kansas — has become the most-specified synthetic in the North Shore replacement market over the last decade. The question we get on Glencoe projects more than any other is: which one is actually going to hold up better in Lake Michigan weather?
Lifespan: what each system actually delivers in Glencoe weather
Hand-split or tapersawn Western Red Cedar shake, installed correctly with breathable underlayment, stainless ring-shank fasteners, and a properly ventilated attic below, typically lasts 25-30 years on a Glencoe home — sometimes longer with periodic cleaning and treatment, sometimes shorter if the attic ventilation was compromised during the install. DaVinci's polymer composite slate carries a 50-year limited lifetime warranty and the field performance over the last 15-20 years backs up a realistic 50+ year service life. The lake-effect freeze-thaw cycles that punish cedar — water absorption, freeze expansion, splitting at the butts — don't affect DaVinci the same way because the polymer doesn't absorb water. In raw lifespan terms, DaVinci roughly doubles cedar's expected service life on a Glencoe home. That's the single biggest argument for synthetic.
Hail and wind performance
Glencoe saw meaningful hail events in 2017, 2019, and 2024. Hail bruises cedar — the strike compresses the wood fibers, the bruise becomes a moisture entry point, and you get accelerated decay around the impact zone over the following 12-18 months. Cedar can survive hail events without showing failure for years, then crash all at once. DaVinci is Class 4 impact-resistant rated, the highest UL designation. In documented hailstorm aftermath on North Shore homes we've inspected, DaVinci-installed roofs have shown essentially no functional damage from events that bruised cedar visibly on neighboring properties. Wind performance is comparable on properly fastened installs of either material — both will hold up to the 70+ mph gusts that hit the lakefront periodically. The difference is how each system ages between extreme events, and synthetic just doesn't accumulate the cumulative weather wear the same way cedar does.
Maintenance reality on a Glencoe property
Cedar requires active maintenance. Plan on a professional inspection every 2-3 years, a moss/algae treatment every 4-5 years depending on tree canopy, and replacement of cracked or weathered courses as they're identified. Homeowners who treat cedar as a fit-and-forget roof are the ones who replace it at year 18-20 instead of year 28-30. DaVinci is essentially maintenance-free. Periodic visual inspection (annual is reasonable) and gutter cleaning are the entirety of the maintenance program. If your Glencoe home is in a heavily wooded part of the village — Beach Park, Ravine Drive, parts of the Village Center — synthetic dramatically reduces the ongoing maintenance burden compared to cedar.
Cost, aesthetic match, and HOA review
Cedar shake on a typical Glencoe home runs $80,000 to $150,000+ depending on complexity, square footage, and copper flashing scope. DaVinci synthetic slate runs $80,000 to $150,000 in the same size range — essentially overlapping price bands for materials and labor, because while the DaVinci shingle itself costs more than cedar per square, the install labor is comparable. On aesthetic match, DaVinci's Bellaforté line replicates slate; the Multi-Width Slate replicates a sawn slate look. Their cedar-shake-look line, the DaVinci Fancy Shake or Single-Width Shake, replicates cedar convincingly from street view but will not pass close inspection as real cedar. Glencoe doesn't have a formal architectural review commission, but properties on Ravine Drive, Beach Park, and adjacent to the historic Village Center should expect neighbor scrutiny and possible covenants in older subdivisions. We've installed DaVinci on Glencoe homes where the homeowner wanted synthetic's longevity but the property history called for cedar's visual character — and the result has been visually acceptable in every case we've documented.
What we'd actually specify on a Glencoe home today
If the home is east of Sheridan Road, has mature tree canopy, has historical importance, and the homeowner intends to stay 15+ years, cedar shake is still the right specification for character — with the understanding that the maintenance and replacement cycle is real. If the home is west of Sheridan, the homeowner wants minimum lifecycle maintenance, the property has had hail history, or this is the second cedar replacement and the homeowner is tired of the cycle — DaVinci is the right specification. Both materials are installed routinely on Glencoe homes by experienced contractors. Both can look correct on the right architecture. The decision usually comes down to maintenance tolerance and how long the homeowner plans to stay. Cedar shake roofing and synthetic slate are both core services we do regularly across the North Shore.
Talk to us before you commit
Cedar shake and DaVinci synthetic slate are both high-stakes specifications. The wrong choice on a Glencoe estate-home roof costs $80K to $150K and 30 years of consequences. We've installed both on Glencoe and adjacent North Shore properties and we'll give you the honest comparison for your specific home, attic ventilation condition, tree canopy, and intended ownership timeline.
