What We Do
Slate Roofing We Install & Repair
A slate roof is the longest-lived roof you can put on a home — natural slate routinely lasts 75–150 years — but only when the underlayment, fastening, and flashing are done right. We install, repair, and restore both natural and synthetic slate, and fabricate the copper details that make them last.

Local Context
Why Highland Park Homes Choose Slate
Highland Park’s older lakefront and ravine-lot estates were built in an era when slate was the default roof for a substantial home, and many still carry it today. On these houses — varied early-20th-century architecture, heavy tree cover, steep rooflines — natural slate fits both the look and the longevity owners expect. The recurring problem isn’t the slate itself; it’s flashing and valleys that have aged past the tile and started to leak. Restoring that metalwork, fabricated to fit the roofline, is the core of what we do here.
- Older lakefront/ravine estates where slate is the original, period-correct material
- Heavy tree cover and steep rooflines that wear flashing and valleys first
- Restoration of aged slate and its failed metalwork, fabricated to match

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 endures on Highland Park’s older estates. 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 restore the slate roof on an older Highland Park home?
Often, yes — and on these older estates it’s frequently the right call. If the slate is sound, we replace cracked or slipped tiles, rebuild the failed flashing and valleys, and restore the roof rather than replacing it wholesale.
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.
