Slate Roof Replacement Price Factors

1. Removal of existing roof. If possible, installing the new roof over the existing one could result in substantial savings.

2. Roof accessories. The addition of soffits, fascia, skylights, ventilation, and solar panels can all drive up the cost of your slate roof replacement.

3. Roof size. Roof installation is often priced based on square footage. There may be additional costs associated with roofs that are larger than 2,000 square feet (or 20 squares).

4. The pitch (slope) of the roof. Steep roofs are difficult to walk on, which may require additional safety equipment during roof replacement and result in additional charges.

5. Your location. Rates to install slate roofs vary depending on where you live.

8. Slate type. Slate roofing can either be natural or synthetic. Synthetic slate is more affordable than natural slate.
