A Brief History of Slate Roofs
Slate roofs have a long and rich history, dating back centuries. Their popularity stemmed from the natural beauty and rugged protection of slate tiles. Quarried from the earth, slate offered a unique blend of elegance and resilience, capable of withstanding harsh weather conditions and lasting for generations. Historic buildings adorned with slate roofs have an enduring appeal and timeless sophistication. Even today, the classic look of a slate roof evokes a sense of quality and craftsmanship that few other roofing materials can match.
However, despite their undeniable beauty and longevity, slate roofs present some significant drawbacks for contemporary homeowners. Slate tiles are incredibly heavy, often requiring additional structural support that can add to the cost and complexity of installation. They also demand specialized installation techniques, necessitating the expertise of skilled roofers who are experienced in working with slate. Perhaps the biggest deterrent for many homeowners is the cost. Slate roofs are significantly more expensive than most other roofing alternatives, making them a luxury that’s often out of reach for the average homeowner.
A Better Alternative
Fortunately, modern asphalt shingle roofing technology has provided homeowners with alternatives that capture the beauty and elegance of slate without the associated drawbacks. CertainTeed Highland Slate shingles are designed to replicate the authentic texture and fleck of natural slate. They’re also far lighter than slate tiles, making them easier and less expensive to install. And because they’re made from durable asphalt, they offer excellent protection from the elements and come with a robust warranty.
If you’re a homeowner who loves the look of slate but is hesitant about the cost and complexity of a traditional slate roof, CertainTeed Highland Slate shingles are an ideal choice. Contact County Roofing Systems today to learn more about the affordable luxury of Highland Slate and discover how we can help you achieve the roof of your dreams.
