Slate roofing is one of the oldest and most enduring roofing systems in the world — valued for its natural beauty, exceptional durability, and historic significance. When properly installed, a natural slate roof can last 100 years or more, making it one of the most prestigious and cost-effective roofing investments over time.
Tredegar Construction specializes in traditional slate roofing systems, combining time-tested installation practices with modern performance standards to protect and preserve remarkable homes.

Natural slate is a metamorphic stone formed over millions of years through intense heat and pressure. Each slate tile is quarried, hand-split, and shaped without additives — resulting in a roofing material that is 100% natural, fire-resistant, and exceptionally long-lasting.
Architectural Beauty: Available in a range of natural colors and blends, slate adds depth, texture, and character unmatched by modern materials.
Sustainable & Environmentally Responsbile: A natural, recyclable material that reduces waste by eliminating repeated roof replacements.
Long-Term Value: While the initial investment is higher, slate often proves more economical over its lifetime than conventional roofing.
Slate roofing relies on a time-tested overlapping installation method that has protected structures for centuries. Each slate overlaps the course below it, creating multiple layers of protection that naturally shed water while resisting wind uplift.
Tredegar Construction installs slate as a functional roofing system, not a surface treatment — respecting traditional methods while incorporating modern underlayments and flashing details where appropriate.
1. Structural Roof EvaluationIf the building does not already have a slate roof, a structural engineer will need to assess the existing roof framing and load capacity to confirm slate compatibility and determine if any framing modifications are necessary primary to slate installation.
2. Slate Selection & Layout Planning
Slate color, size, thickness, and pattern are discussed to match the architecture of the home and the homeowner’s vision for the project. Layout planning ensures proper proportion, exposure, and visual balance.
3. Traditional Installation
Each slate is individually installed using copper nails, maintaining proper headlap and spacing to create a durable, breathable, multi-layered roofing system. All copper flashings are installed to withstand the friction caused by slate movement over time.
4. Final Inspection & Long-Term Guidance
Once complete, we inspect all details and provide guidance on long-term care, maintenance, and repair considerations for slate roofing systems.
