Roof Boot Installation Instructions

  1. Cut a hole in the roof cladding slightly larger than pipe. Support hole with additional framing if necessary. Insert pipe into hole. Trim cone of Roof Boot with sharp snips for a snug fit on the pipe. MASONS RBFBE0 20MM Roof Boot Flashings - Roof Boot Installation 1
  2. Slide the Roof Boot down over the pipe. Moisten the pipe to overcome friction and slide the Roof Boot down into position.
  3. Apply roof and gutter or similar neutral cure silicone to the underside of the Roof Boot flange.
  4. Press flange onto roof cladding and silicone. Mould to shape easy out any creases. Don’t over stretch the billowed cone adjust the fit on the pipe as required. Leave some ‘give’ in the flexible cone to allow for minor movement.
  5. Finish by applying at continuous bead of silicone to the edge of the flange and smooth off.
  6. Use self drilling washered screws or sealed rivets to fasten the Roof Boot to the cladding.

NOTE: For more effective drainage, always fit the Roof Boot 45° to the fall, or diamond fashion.

Roof Pitch

Roof boots have limitations regarding the pitch, roof profile and placement.
For roof boots fixed directly to the roof cladding where the roof boot fits cross the entire pan of the profile the lowest permissible roof pitch is 8° for corrugated iron and 10° for low rib trapezoidal profiles.
Where possible avoid fitting roof boots over a lap. If this can not be avoided the lap must be fully sealed.
The installer must take actions needed to prevent the possibility of leaks through capillary action.
Directly fitted roof boots should be fitted with their edge’s diagonal to the fall of the water. If this is not practical, they may be fitted square at pitches 10° and above.

Boot flashings fitted to Over Flashings
Roof boots may be fitted to over flashings, this allows them to be used in pitches down the minimum allowed for the profile, this is usually 8° for corrugated and 3° for trapezoidal trough sections. Under 10° pitch roof boots must be installed at 45° to the profile – fall of the roof.
Soaker flashings should continue to the apex or terminate with a soaker to the upper edge.
For additional information Masons recommends designers and installers consult the MRM COP section 9.5, and Or E23 AS1 section 8.3.10 and figs 53 & 54 prior t detailing or using Masons Roof Boots
Masons recommends the use Soudal Gorilla MS or Gorilla Roofers silicone, or any equivalent premium neutral cure sealant.
