How should starter shingles be positioned relative to the eave and overhang?

• A. Installed at the top edge with minimal overhang
• B. Installed at the lower edge with the correct overhang per manufacturer instructions, forming a straight starting line for field shingles
• C. Placed randomly across the eave
• D. Laid over the ridge line

Answer: (B)

Starter shingles belong at the eave with the lower edge aligned to the roof edge and the overhang set to the manufacturer’s specification. This setup creates a straight starting line for the field shingles, which is essential for clean alignment and proper water shedding. If the starter is placed at the top edge or with too little or too much overhang, water can weep under the first course or the rows won’t line up correctly, increasing the risk of leaks and wind damage. Laying starter shingles randomly or over the ridge prevents establishing a solid base and fails to provide the necessary drip edge and alignment for the rest of the shingles.
