1. Make sure there are no nails
or other objects protruding from
the substrate that might punc-
ture the underlayment or dam-
age 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 synthetic underlayment
(hereinafter referred to as un-
derlayment). Begin at the eave
at the gable end and roll out the
underlayment horizontally (par-
allel to the eave). Allow each consecutive course to overlap the previous one by 4-6”. 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) Ice &
Water shield should be used in cold climates starting at the eave and extending at least 24” past exterior
walls. Tip: To reduce the risk of plywood clips showing through the panels, place a 6”x 6” piece of peel and
stick underlayment or 30lb felt over plywood clips prior to installation of underlayment.
4. Place an alignment line along the gable end where the rst roof panel will be installed. THIS LINE
MUST BE LOCATED 1/2” IN FROM THE GABLE EDGE OF THE ROOF DECK AND SQUARE WITH THE
EAVE LINE. Various methods exist for ensuring that the line is square. Call your nearest FABRAL repre-
sentative if you need assistance. (See Illustration #2)
