Slate Roof Installation in Spokane, WA
Slate roofs last 75 to 200 years when installed correctly. In Spokane, heavy snow and freeze-thaw cycles challenge many roofs. Our licensed installers handle slate's 800 to 1500 pounds per square load. We prevent leaks by focusing on flashing details and underlayment.
Common pain points include cracked tiles from poor support and water damage from improper valleys. We inspect structures first to ensure rafters meet code. This avoids costly repairs later.
- Start with a full roof assessment for pitch, decking, and load capacity.
- Select durable natural slate from quarries, graded for thickness uniformity.
- Install ice and water shield underlayment for extra protection.
- Lay tiles with two nails each, overlapping for runoff.
- Add metal flashing at edges, vents, and penetrations.
- Clean site daily and test for leaks before final walk-off.
The process takes 4 to 6 weeks for average homes, depending on size. Crews work in phases to minimize disruption. We follow International Building Code standards for Spokane County.
