Frequently Asked Questions

Slate roofing questions answered

Is slate roofing worth the high cost?

Absolutely. Slate is a once-in-a-lifetime investment. You'll never need roof replacement, and the home value appreciation often offsets the installation cost.

Can you walk on a slate roof?

Walking on slate can damage tiles. The surface is also slippery. Professional maintenance should be done carefully or not at all.

What if a slate tile is damaged?

Damaged tiles can be replaced, but slate matching is difficult. This is why selecting quality slate and professional installation is critical.

Does slate roofing qualify for insurance discounts?

Yes, many insurance companies offer substantial discounts for slate roofing due to its fire resistance and durability.

Will my home's structure support slate?

Slate is heavy (6.5-15 lbs per sq ft). Older homes may need structural reinforcement. We assess this during consultation.
