A Daily Seal for Roofing Projects

Most commercial roof projects are too large to be completed in one work day. This means that each day, the work which was completed needs to be sealed up or terminated until the next work day.

This includes temporary closure of the membrane to prevent water infiltration. Some steps to creating a daily seal include:

1. Temporarily seal any loose membrane edges down-slope using Sure-Seal® Two-Part Pourable Sealer (EPDM only), Flexible FAST™ Adhesive, VapAir Seal™ Flashing Foam, hot asphalt, or a similar product so that the membrane edge will not buck water. Caution must be exercised to ensure positive draining during installation, and temporary seal locations should be designated so that drainage is not restricted by partially installed roof sections during construction.

2. After embedding membrane in daily seal material, it is important to CHECK FOR CONTINUOUS CONTACT. Provide continuous pressure over the length of the temporary seal. Provide weight evenly distributed along the length of the daily seal. This will help to reduce the wind effect on the continuous temporary seal.

3. When work is resumed, pull the embedded membrane free, then trim and remove daily seal material from membrane before continuing installation of adjoining sections.
