How should you address weather conditions that could affect shingle installation?

• A. Postpone work during rain, high winds, or extreme temperatures; protect underlayment and shingles; allow surfaces to dry before resuming; follow manufacturer temperature guidelines.
• B. Continue work regardless of weather to meet deadlines.
• C. Only postpone if it starts to rain.
• D. Weather has no impact on installation.

Answer: (A)

Weather shapes how shingles perform, so the best practice is to plan around it. Rain, high winds, and extreme temperatures can prevent proper sealing, trap moisture underlayment, and affect adhesive curing, leading to leaks, warped shingles, or failure to stay in place. By postponing work during unfavorable conditions and protecting the underlayment and shingles, you give surfaces a chance to dry and materials to behave as designed. Then resume only when conditions meet the manufacturer’s temperature guidelines to ensure proper bonding and long-term performance.
