Best Practices Manual

Whenever a roof surface abuts a vertical wall surface, moisture intrusion and rot become a risk at the connection between the two planes.

Kick-out flashing, a somewhat forgotten practice except by the best roofers, addresses this risk at the most vulnerable intersection between sloped roofs and walls: the drip edge.

• Be sure to leave space between the end of the fascia and the wall where FastFlash, WRB, and siding can slide up.

• Install FastFlash along the wall at the roof edge.

• Stick top edge of transition strip membrane to FastFlash.
• Bead and tool FastFlash to the top edge of transition strip.

• Peel and Stick along the edge of the roof and lap over top of fascia.

• Attach drip edge.

• Install Peel and Stick the entire length of the roof-to-wall intersection.

• Attach roofing felt. Extend 4” up the wall.

• Nail on starter strip of roofing material.

Kick Flashing Guide
Note: All Kick-Out Flashing fabricated on site must have welded seams.

• Fasten kick flashing in upper right corner.

• Install first course of shingles.

Step Flashing Guide
Note: Align with top edge of shingle course.

• Fasten stepped flashing.
• 2” minimum overlap with preceding piece of flashing. Top of flashing piece should align with top of shingle course.

• Continue alternating shingle course and stepped flashing until the roof is complete.

• Install Peel and Stick over the stepped flashing.

• Slip WRB as high and tight as possible under the transition strip membrane.

• Continue layering WRB up to the top of the wall.
• 4” minimum overlap between sheets.

• Install siding.
• Allow for a 2” clearance between bottom of siding and roofing material to avoid water damage.

• Install gutter under drip edge.
