Find panel counts and lengths for a gable roof from your eave length and panel coverage.
How it works
Eave length ÷ panel coverage, rounded up, per side. Panel length is the sloped run plus overhang.
Before you order
- Count by coverage width, since panels overlap at the seams.
- Order a panel or two extra on long roofs.
- Check minimum slope and fastening in the manufacturer’s guide.
Common questions
Should metal panels overhang the eave?
A small overhang is typical. Follow the manufacturer’s limit.
Can I cover shingles with metal?
Sometimes, but code and warranty rules vary by location.
