Repair or replace?

Slate itself often outlasts its fasteners and flashing by decades. Before accepting a tear-off quote, get an opinion from a contractor who specialises in slate - many apparent failures are flashing failures.

Virginia-specific considerations

Slate is common in Richmond, Charlottesville, Alexandria, Lynchburg and Roanoke. Some historic districts require slate or a visually compatible substitute - confirm before choosing an alternative.

Questions to ask contractors

• How many slate projects have you completed, and can I see them?
• Will you repair rather than replace where the slate is sound?
• What flashing metal do you use, and what is its expected life?
• Are you licensed in Virginia, and what is your license number?
• Can you provide a current certificate of general liability and workers' compensation insurance?
• Who pulls the permit, and which jurisdiction issues it?
• What is included in the written scope - underlayment, flashing, ventilation, decking allowance and disposal?
• What warranty covers workmanship, and what covers materials?
• Who will be on site each day, and is the crew employed by you or subcontracted?
