If you’re considering a slate roof replacement, understanding the slate roof replacement cost and long-term benefits will help you make an informed decision. In this guide, we’ll break down costs, factors affecting pricing, and why a slate roof is a worthwhile investment for your home.
What Influences Slate Roof Cost in Dover, NH?
The cost of installing or replacing a slate roof depends on several factors. Here’s what affects the overall price:
Type and Quality of Slate
Slate comes in various grades and thicknesses, which impact durability and cost.
- Natural Slate: High-end material that lasts over a century, costing between $10 to $30 per square foot.
- Synthetic Slate: A budget-friendly alternative made from rubber or plastic composites, costing $4 to $10 per square foot.
- Imported vs. Domestic Slate: Domestically sourced slate is often more affordable than imported varieties from regions like Spain or China.
Labor and Installation Complexity
Slate roofing requires specialized skills, increasing labor costs. Professional slate roofers in Dover, NH, charge $50 to $100 per hour, with total labor costs ranging from $5,000 to $15,000 depending on roof size.
Roof Size and Slope
A larger roof or steep pitch increases the amount of slate needed and installation time. Roofing complexity affects material waste and labor expenses.
Underlayment and Structural Reinforcement
Slate is significantly heavier than asphalt shingles, often requiring additional structural support. Reinforcement can add $1,000 to $5,000 to the project cost.
Slate Roof Replacement Cost in Dover, NH
If your current slate roof is aging or damaged, slate roof replacement cost is an important consideration.

Factors such as roof accessibility, disposal fees, and additional repairs influence replacement costs.
Cost Comparison: Slate vs. Other Roofing Materials
While slate roof cost is higher than asphalt or metal, its lifespan and durability make it a worthwhile investment.
| Roofing Material | Lifespan | Cost per Square Foot |
| Asphalt Shingles | 20-30 years | $3 – $7 |
| Metal Roofing | 40-70 years | $5 – $15 |
