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.
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.)

Place an alignment line along the gable end where the first roof panel will be installed. THIS LINE SHOULD
BE ½” 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 Dealer if you need assistance.
