Masons Roof Boot Flashings are designed for building applications where a pipe
or building service penetrates the roof of a building.
When installed the roof boot flashings create a weathertight seal between the
service pipe and the building roof.
AVAILABLE IN MULTIPLE SIZES 0-300mm And either EPDM Rubber or Red Silicon
EPDM withstands temperatures from -50˚C to 115˚C and up to 150˚C
intermittently.
Silicon withstands temperatures from -60˚C to 200˚C and up to 250˚C
intermittently.
WHEN A SQUARE FITTING IS REQUIRED ADD 30%
TO THE DIAMETRE OF THE PIPE AND CUT ACCORDINGLY.

Roof Boot Installation Instructions
- 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.
- Slide the Roof Boot down over the pipe. Moisten the pipe to overcome friction and slide the Roof Boot down into position.
- Apply roof and gutter or similar neutral cure silicone to the underside of the Roof Boot flange.
- 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.
- Finish by applying at continuous bead of silicone to the edge of the flange and smooth off.
- 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.
