What Our Roof Installation Service Includes
A proper roof installation is about more than nailing down shingles. Here’s what’s included with every project:
- Free on-site estimate — we inspect the site, discuss materials, and give you a clear, honest number
- Removal of old roofing (if applicable) — proper tear-off and disposal, done cleanly
- New underlayment and decking inspection — we don’t install over hidden problems
- Premium material installation — asphalt shingle, tile, or flat roofing systems, installed to manufacturer spec
- Flashing, vents, and ridge caps — the details that determine whether a roof actually holds up
- Final walkthrough and cleanup — including magnetic nail sweep of the property

Flat Roofing
Ideal for additions, garages, and modern-style homes, installed with proper drainage and waterproofing to prevent pooling and leaks.
