What Is a Starter Strip?

A starter strip is the first row of roofing material installed at roof edges to help seal and secure the first shingle course.

A starter strip is installed at the roof edge before the first full row of shingles. It helps seal and secure the beginning of the shingle system.

Why It Matters

Roof edges are vulnerable to wind and water. Starter strip helps the first course of shingles bond correctly and gives the roof edge a cleaner, more secure installation.

Common Problems

Problems include missing starter strip, using cut-up shingles incorrectly, poor alignment, exposed seams, and failure to coordinate with drip edge.

Exterior Echelon Notes

Exterior Echelon checks starter courses because roof-edge details can affect wind resistance, water shedding, and the finished appearance of the roof.
