Slate Roofing FAQs
How much does a slate roof cost in Toronto?
The cost depends on roof size, pitch, slate type and how much repair or removal is needed. Slate costs more upfront than most materials, but its long life makes it good value over time. DVR Roofing provides a free inspection and a written quote so you know the exact price before work begins.
How long does a slate roof last in Ontario?
With proper installation and maintenance, slate roofs can last 75–100+ years. The quality of the slate, flashing and workmanship all affect lifespan, and Ontario freeze-thaw cycles make correct installation especially important.
Is slate roofing worth the cost?
For most long-term homeowners, yes. Slate has a higher initial cost, but it lasts several times longer than common roofing materials, needs little maintenance and adds curb appeal and resale value.
Can my house support a slate roof?
Slate is heavy, so the roof structure must be able to carry the load. During our inspection we check the framing and deck, and we tell you honestly if any reinforcement is needed first.
Should I repair or replace a damaged slate roof?
It depends on the condition of the roof. If the slate is sound and only a few tiles or flashings have failed, repair is usually enough. If many tiles are brittle or the underlayment has failed, replacement may be the better investment. We explain both options.
Can slate roofs be repaired?
Yes. Cracked, slipped or missing slate tiles can be replaced individually, and failed flashing can be repaired or renewed. Repairs should be done by a roofer experienced with slate, because walking on or fastening slate incorrectly can cause more damage.
Do you work on heritage homes?
Yes. Older homes often have slate that needs careful repair or matching. We inspect the existing roof and recommend work that preserves the character of your home.
How often should a slate roof be inspected?
We recommend an inspection about once a year and after any major storm, since cracked or slipped tiles and worn flashing are easy to miss from the ground.
How long does a slate roof installation take?
It depends on roof size, complexity and weather. Small repairs can often be done in a day, while a full slate roof takes longer. We give you a timeline with your written quote.
Does slate roofing add home value?
Yes. A well-kept slate roof improves curb appeal and is a premium feature many buyers value, which can support your resale value.
Is slate roofing fire resistant?
Yes. Slate is natural stone and is highly fire resistant.
