A good slate roof can last a hundred years — if it's repaired by people who know slate. Most slate problems are flashing and fastener problems, and most are fixable without replacing the roof.

Repair first
Slate itself rarely wears out. What fails is the stuff around it: rusted nails letting slates slip, worn valley metal, deteriorated chimney flashing. A careful repair can add decades to a slate roof — and should always be considered before replacement.
Walking slate the right way
Slate breaks under careless foot traffic. We use proper staging and ladder hooks so the repair doesn't cause more damage than it fixes.
Alternatives
For homes that want the look without the weight or cost, composite options like Brava deliver a slate appearance on a lighter, impact-resistant tile.
Frequently asked questions
Can you match my existing slate?
Usually, using reclaimed or new slate matched for color, size and thickness.
Does a slate roof need to be replaced?
Often not. Most issues are flashing and fasteners. We'll tell you honestly what the roof needs.
How long does a slate roof last?
Quality natural slate commonly lasts 75 to 100 years or more. The flashing and fasteners usually need attention long before the slate itself does.
Is there a lighter alternative to slate?
Yes. Brava composite slate gives a similar look at a fraction of the weight, and designer shingles offer a slate profile at a lower cost.
