The Roof System
Your roof is
more than shingles.
Two contractors can quote the same shingle and deliver two completely different roofing systems. Long-term performance depends on the materials underneath, the treatment of vulnerable areas, ventilation, fastening, flashing, and the discipline of the installation.

Roof System Component
Field Shingles
- What it does
- The visible roof covering that sheds the majority of water and weather.
- Why it matters
- This is what most homeowners compare — and the only part most quotes describe.
- When it's missing or wrong
- Correct product with incorrect exposure, offset, or alignment still shortens roof life.
- What Dominion evaluates
- Exposure, offset, and course alignment are inspected during and after installation.
