Reroofing

There are two options available for reroofing installations. The first option is to tear off the old roof before applying the new one (tear off). The second would be to lay new shingles over the existing roof (lay over). While the second choice is the less expensive of the two options, it is not necessarily always the best choice. There are advantages to tearing off the old roof before installing a new one.

For Example:

  • If there are any defects in the roof deck, they will be revealed when the roof is torn off. These defects should be repaired before applying the new roof.
  • If condensation problems exist in the attic, they too will be revealed when the roof is torn off. Properly designed attic ventilation can then be installed in order to help eliminate such problems.
  • When the old roof is torn off, waterproofing shingle underlayment can be installed before applying the new roof. This will help protect against leaks created by cyclical ice damage and wind-driven rain.
  • Tearing off the old roof and starting with a clean deck before reroofing may result in a smoother finished roof system.

Some states have specific rules for shingle overlay. Depending on the number of shingle layers on your roof, the shingles may have to be completely removed before work can begin.
