“Depending on where the slate roof was quarried, the qualities, color and longevity vary. The advantages, generally speaking of roofing slate, are many: it is fireproof, strong enough to resist hail storms, aesthetically appealing and can last a century or even longer.”
Slate roof costs are hard to set in stone due to many factors. Generally, each piece costs $8 to $12. Depending on the quality of the material, installation costs range from $300 to $2,000 per 100 square feet. As experienced contractors like The Roofing & Remodeling Company will point out, slate roofs may seem pricey at first, but their cost per year over their service lives is among the lowest.
Typically, slate roofs can last longer than asphalt shingles and metal roofs. Asphalt shingles are good for 20 years and metal roofs stay strong for at least 60 years, but slate can last for more than 100 years.
The answer is minimal to none at all. As mentioned earlier, slate roofs feature fire and weather resistance, as well as invulnerability to rot. They are prone to being broken if stepped on, but they should be fine with careful attention. Even roofing contractors in Virginia Beach, VA take great care when installing or repairing them.
