Local Context

Why Glencoe Homes Choose Slate

Glencoe is dense with architect-designed and lakefront estate homes of real architectural pedigree, where slate has always been the period-correct roof — a century-long material on steep, detailed rooflines among the village’s heavy tree canopy and ravine lots. Natural slate matches both the architecture and the expectation that these homes endure. As ever with slate, the weak point is the metalwork: flashing and valleys that fail before the tile does. Fabricating and fitting that copper detail in-house is exactly what these roofs need.

We Fabricate the Copper Flashing In-House

Slate roofs almost never fail at the tile — they fail at the flashing and valleys. We form those copper details in our own shop to fit your roof, where off-the-shelf parts leak.

Slate Done Right

Proper underlayment, fastening, and headlap — the difference between a slate roof that lasts a century and one that fails in fifteen years. Slate is unforgiving of shortcuts; we don’t take them.

Workmanship Warranty

Beyond slate’s own generations-long life, our installation is backed by a workmanship warranty, in writing.

FAQ

Common Questions

How long does a slate roof last?

Natural slate routinely lasts 75–150 years — often longer than the building itself — which is why it’s a favorite on Glencoe’s architect-designed homes. Synthetic slate typically carries a 40–50 year warranty at a lower cost and weight.

Natural slate or synthetic — which is right for my home?

It depends on budget, the look you want, and whether your roof structure can carry natural slate’s weight. We’ll walk you through the trade-offs honestly: natural slate for longevity and authenticity, synthetic for a lighter, lower-cost roof that still reads as slate.

Can you repair or restore my existing slate roof?

Often, yes — and on Glencoe’s older architect-designed homes it’s frequently the right call. If the slate is sound, we replace cracked or slipped tiles, rebuild failed flashing and valleys, and restore the roof rather than replacing it.

Is my home strong enough for a natural slate roof?

Natural slate is heavy, so the structure has to support it. We assess that up front and tell you honestly — if your home isn’t built for natural slate, synthetic gives you the look at a fraction of the weight.

Do you fabricate the flashing yourselves?

Yes. We form the copper flashing, valleys, and snow guards in-house and cut them to your roofline. With slate, the metalwork is where roofs leak — so we don’t subcontract it.
