Sidewall, Endwall & Headwall Counter Flashing Installation

How to Install Metal Roofing: Sidewall & Endwall - Flashings used when a roof intersects with a wall either on the side of the panels (Sidewall) or at the top of the panels (Endwall).
Headwall Counter Flashing is then attached to the top of the Sidewall & Endwall and sealed with caulk as the final line of defense against leaks.
SIDEWALL TIPS:
◊ Install butyl tape along the bottom edge of the sidewall flashing.
◊ Once sidewall is in place, fasten at 12” on center with Premium Woodscrews.
◊ Be sure to apply your butyl tape sealant along the top edge of the sidewall where
the fasteners will be installed. This creates your weathertight seal.
◊ As with Endwall flashing, counterflashing can be added here. If preferred, a caulk
edge can be modified as well.
◊ *Purlins should be installed 1” from the wall.
ENDWALL TIPS:
◊ Once panels are installed, install outside closures at the point where the Endwall
flashing will be fastened down.
◊ The top edge of the Endwall can be secured in a few different ways. Generally it
is tucked under the house siding. However, in cases where there is no siding,
counterflashing can be added as another form of protection. Counterflashing also provides a more finished look. See MFMRS Flashing Profile #34
◊ In some cases, when counterflashing cannot be added, the Endwall flashing can
be modified to allow a caulk edge where permathane sealant can be used.
◊ *Purlins should be placed 2” from the wall.
