- Once you spot the suspected source of the leak, gather your tools.
- Mount the ladder in a stable place and climb onto the roof very carefully.

Curling asphalt shingles
- You may be able to flatten curled shingles that have exposed your roof decking.

- Dab roofing cement over nail heads.
- Push the new shingles down so they’re flat against the roof.
