Installation of EasyFit roof trims

Before laying the waterproof membrane

Fix a rot proof batten (approx. size 25mm x 50mm) around the roof perimeter, level with the top of the roof deck. Fix the back drip edge trim to the batten adjacent to the gutter. (see drip edge section). Apply the waterproof membrane over the roof and trim off surplus at the bottom edge of the batten or back drip edge trim.

Cut and fold the membrane flat around the roof corners, when installing thin single ply membranes. When using thick felt membranes try using a EasyFit rubber corner cap inserted under the felt then cut the felt to the corner angle. This simple idea keeps the corner flat and waterproof and allows the corner trim to fit snugly against the corner of the roof.

Check kerb trim

The EasyFit check kerb trim is designed to secure the edge of the waterproof membrane and stop the water going over the roof edge. Installation is quick and simple (see design drawing.)

1. First fix the corner sections. Slide the corner section down onto the roof to compress the seal, gently hammer the fixing pins through the centre of the fixing slots, don't fix the pins to tightly against the trims.
   
   
2. Butt the first trim up to a corner section, compressing both seals together. Important on very cold days allow a minimum expansion gap of 5mm between the trims. Then gently hammer the fixing pins through the centre of fixing slots.
   
   
3. Apply a bead of silicone to one side of the joint, (this will hold the check kerb joint clip in place).
   
   
4. Apply the check kerb joint clip by hooking it under the bottom edge of the trim and at the same time snap the top of the clip over the top section of the check kerb.
   
   Notes:
   Cut the trims down to length if necessary using a sharp saw. Drill trims with a 5mm long slot if further fixings are required. Always make sure two rubber seals are between the joints. Slight marks can be removed using jiff (cif) cream cleaner and a soft cloth.
   

When Installing on very cold days allow a gap of at least 5mm between the trims.

Drip Edge Trim

The drip edge trim is designed to firmly secure the membrane over the edge of the roof and allow the water to flow over the trim, into a gutter.

1. First, fix the back edge drip trim onto the 25mm x 50mm batten using the nails provided. make sure the bull nose top section of the back edge trim is level, or just below the top of the batten. Also fix a back edge corner section if extending the drip edge around the corner.
   
   
2. Extend the waterproof membrane over the back edge trim and cut off at the bottom edge.
   
   
3. Fix the front drip edge trim over the membrane by firmly pushing down on the trim to compress the seal and at the same time drill a 2mm pilot hole through the front trim slot, into the back trim. Now pin through both trims using fixing provided. The top section of the trim should now be level or just below the level of the roof to allow the water to pass over it and into the gutter.
   
   
4. Finally fix the joint clips as per item 3.

When Installing on very cold days allow a gap of at least 5mm between the trims.
