Ask for the findings
Request photos and an explanation of shingle condition, flashing, leaks and decking concerns. Make sure you understand whether the recommendation addresses aging, damage or both.
Check local requirements
Licensing requirements vary. Verify any required license and ask for current insurance information before work starts.
Understand the proposed treatment
Ask which product is proposed, what evidence supports its use on your shingles, and what it cannot repair. Check manufacturer and insurer requirements separately.
Compare written scopes
Look beyond the total price. Compare preparation, repairs, application, weather requirements, cleanup and any written warranty terms.
You should have time to understand your options before making a decision.
