Roof Top Heat & Glue top layer

Step-by-step plan

1. First dry the existing roof covering and remove all dust and grease. In the case of renovation, repair any blisters, cracks and tears in the weathered bitumen substrate with elastic ROOF REPAIR REGULAR. Reinforce with ANTI-CRACK, a tear-resistant polyester fleece. For optimum adhesion of the new roof covering to old roofing, apply 1 coat of ROOF PRIMER ROOFING bonding varnish, which fixes any residual dust.
2. Place the ROOF TOP HEAT & GLUE on the roof surface. Always start at the lowest point of the roof, i.e. the side with the rainwater outlet. Lay the top layer in the same direction as the underlay or the existing roof covering used as an underlay, but staggered by 50 cm. To achieve this, halve the width of the first roll of roofing membrane. This type of roofing membrane can be glued with ROOF GLUE ROOFING or heat welded.
3. Place the roll where you wish to install it, unroll it a little with your foot and align it. Then roll it back up. Aim the roofing torch at an angle towards the bottom of the roll (30% of the flame towards the roll and a maximum of 70% towards the roof surface). Slowly move the roofing torch from one side of the roll to the other. Unroll the roofing membrane by pushing the roll with your foot. The membrane only needs to melt a little before advancing. Never aim your roofing torch at one spot for too long. When you have heated the membrane sufficiently, a small bead of liquid bitumen will be visible at the edge of the roll.
4. When installing the next roll of roofing, ensure an 8 cm overlap lengthwise. Cut the roll to size, align it and then roll it up again. Install the roll of roofing with a roofing torch. Ensure a 15 cm overlap in the width (the end seams between the rolls). Make sure the end seams are staggered relative to the underlying and adjacent roofing membranes. Always cut the roll to size, align it and roll it back up before heat welding it in place. Continue working like this until the roof surface is covered.
5. Finish the roof upstands with strips of ROOF TOP HEAT& GLUE. Ensure the strip covers the upstand completely and 15 cm of the roof surface. Cut the roofing membrane into strips of the correct length. Cut the corners of the strips at an angle.
6. Start in the corner of the roof upstand. Cut the strip at an angle at the upper intersection of the roof upstand. Make a second angled cut in the corner of the roof upstand. Heat the lower parts first and work your way up.
7. Now finish the other side of the corner. Cut the strip to size and cut the corners at an angle. Cut the strip at an angle. Carefully fold the strip into the corner. Heat the lower parts first and work your way up.
8. First cover the upstands with strips. Cut the strips to size. Cut the corners at an angle and ensure an overlap of at least 10 cm. Remove the slate granules from areas where there will be an overlap. Do not start heat welding until all the strips are ready. Press the strips firmly into the corners of the roof upstand. Make sure there are no gaps. Use a roof roller to ensure proper adhesion.
