T-Roof Epic

Preparation: Installation is done with strips across the direction of the roof slope. Rolling is done from right to left so that the side inside the roll becomes the top side when unrolled. The strips are easiest laid from the bottom with overlapping subsequent ones upwards. The surface should be dry, even, and stable to avoid sagging and movement.

Nailing and seam gluing: Mechanical fastening for concealed attachment should be corrosion-protected staples type Rapid 140/10 or larger staples with leg length 12-15 mm, back width 12.4-15 mm (wire dimension 0.5 x 1.3 mm) or alternatively roofing felt nails min 25 x 2.5 mm. For open fastening in joints, hot-dip galvanized nails should be used!

The fastening is concealed in the upper adhesive edge of the lower sheet. The overlapping sheet is adjusted, fastened, and the protective film on the adhesive edges is removed. Then the overlap is pressed together so that the fastening remains hidden. Alternatively, the fastening is open when the roof slope is greater than or equal to 14° (1:4).

In case of any transverse joints, approved roofing felt adhesive is used. For more detailed installation instructions and other detailed solutions, see the separate installation guide (included with each roll and available in digital format on the website).

• When covering with flat roof tiles, the supplier's guidelines for the underlay must be followed!
• The underlay should not be combined with surface layers that are hot air mounted (welded).
• For concealed fastening, carefully check the strength of the joint after installation. Consider severe weather conditions
  circumstances and ensure any temporary fixing of overlaps or protective covering until the permanent surface layer is installed!
• The adhesive edge has aggressive adhesion under normal conditions! In cooler weather (<+10°C), there may sometimes be a need to improve the adhesion. Use a heat gun and gently warm the adhesive surfaces. Press the seam together carefully! In cool weather, rolls should be pre-stored for at least 1 day in a warm storage.
• Be mindful to gently load the surface and immediately repair any damage with roofing felt adhesive Sealant K-36 or equivalent repair compound for bitumen waterproofing. For larger damage, use and attach/glue a strip from the underlay fabric.
• Always cover with the surface layer (tiles, sheet metal, etc.) as soon as possible to avoid exposure to sunlight and
  poor weather conditions. During construction, the underlayment can be exposed to sunlight for up to a maximum of
  12 months. During the usage stage, the underlay must be protected by the outer roof covering.
• Rolls should be stored upright on a flat, dry surface and protected from sun and precipitation.
• T-Roof Epic is diffusion-tight and when mounted on a wooden substrate, the space underneath should be ventilated according to standard practice.
