NEW ROOFS
1. Make sure there are no nails or other objects protruding from the substrate that might puncture the underlayment or
damage the roof panels. Clean all debris from the deck. Check for any high or low spots in the deck, which will cause
waviness in the metal panels.
2. Check all details for possible roof penetrations, which must be added to the deck prior to roof panel installation (vented
ridge for example).
3. Cover the entire roof deck with 30-pound felt paper, Typar or equivalent (hereinafter referred to as underlayment).
Begin at the eave at the gable end and roll out the underlayment horizontally (parallel to the eave). Allow each
consecutive course to overlap the previous one at least 4”. Overlap the end a minimum of 6” when starting a new roll
of underlayment. Areas of underlayment that have been torn or cut should be replaced or repaired prior to installation
of the metal roof. (See Illustration #1 below)

4. Place an alignment line along the gable end where the first roof panel will be installed. THIS LINE SHOULD BE
LOCATED 1/2” IN FROM THE GABLE EDGE OF THE ROOF DECK AND SQUARE WITH THE EAVE LINE. Various
methods exist for insuring that the line is square. Call your nearest FABRAL representative if you need assistance.
