Valley Application
To notch the panels, cut 2” off of the front and back Clip-Locks of each
panel on the side that fits into the Shingle Valley. The first panel on each
side at the bottom of the valley must also have a 1” notch cut 4” from the
end of the panel where it fits into the DECRA Shingle Valley. The figure
below shows the areas that must be notched.
The Shingle Valley must be positioned along the center line of each valley
area. Overlap valley a minimum of 4” over the valley piece below. Fasteners
should be positioned outside the last turn-up on each side. Cut Shingle
panels to length and notch where they fit into the Valley piece. Shingle
Valley Cap (stone coated) can be installed by snapping or sliding into place
(as shown below). Fasten Cap to Valley where required.
■
Roof Penetrations
Roof penetrations should be finished by installing standard roof jacks over a
corrosion resistant Underpan which drains over the panel immediately
below. A 2” wide notch must be cut out of the front Clip-Lock of the
Shingle panel covering the jack. This will allow water drainage from the
Underpan onto the Shingle panel below.
■
Roof-To-Wall Side Flashings
Install the Roof-To-Wall Channel allowing it to extend 3/4” beyond the
fascia or onto the panel below. Cut the Shingle panel to length. Make a 2”
notch at the front and back Clip-Locks where the panel fits into the Channel.
Lock the panel into place and screw down.
NOTE: Do not use lead or copper with this steel roofing system.
