Current building codes in most North Texas municipalities now strictly enforce the installation of drip edge on all eaves and rakes. This metal flashing is critical for directing water away from the fascia and preventing rot in the roof deck.
During insurance adjustments, drip edge is frequently a 'code upgrade' item. If a home was built before these requirements were adopted, the insurance carrier should cover the additional cost if the policy includes Law and Ordinance coverage.
Proper installation requires the drip edge to be applied beneath the underlayment at the eaves and over the underlayment at the rakes. This ensures that any water bypassing the shingles is successfully channeled into the gutter system.
Failure to install this component can lead to denied municipal inspections and long-term structural damage to the perimeter of the home.
