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.
