Roof Base Nail & Glue

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 BASE FIX 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. ROOF BASE FIX can be glued or nailed depending on the substrate (nails for wood/glue for other materials or old roofing).
3. Apply 1 coat of Roof Glue Roofing to the substrate with a floor squeegee or brush where the roofing membrane will be installed. Place the roll in the glue then unroll the roofing membrane over the glue, pushing it with your foot. Make sure the glue is spread over the entire width of the roll. If necessary, add some more cold glue. Press the seams well with a seam roller. The glue should protrude from under the edge of the roll.
4. When installing the next roll of roofing, ensure an 8 cm overlap lengthwise. Cut the roll to size and then roll it up again. Apply cold glue where the roofing membrane will be installed, then unroll the roofing over the glue.
5. 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 of roofing to size and roll it back up before applying the cold glue. Continue working like this until the roof surface is covered.
6. Finish the upstands with strips of ROOF BASE FIX. Ensure the strip covers the roof 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.
7. 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. Apply cold glue first, and then apply the strip. Now finish the other side of the corner. Cut the strip to size and cut the corners at an angle. Carefully fold the strip into the corner. Apply cold glue first before applying the strip.
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 applying the cold glue 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.
