T-Roof YEM 1000

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 and with overlapping subsequent upwards. The substrate should be dry, even, and stable to avoid deflection and movements.

Mechanical fastening for concealed fastening shall 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 roofing felt nails min 25 x 2.5 mm.

Alternatively, the fastening occurs open when the roof slope is greater than or equal to 10° (approx. 1:6).
For open fastening in joints, only hot-dip galvanized roofing nails should be used! The fastening goes through both sheets in the overlap.

In case of any transverse joints, approved roofing felt adhesive (K-36 or T-Fix) is used.
For more detailed assembly instructions and other detailed solutions, see the separate assembly manual.

• The permanent surface layer determines the minimum roof slope for the underlay, but always at least 1.5° (1:40).
• Consider roof slopes <14° (<1:4) where the underlay may be exposed to precipitation and/or where the outer roofing is not installed directly. Apply the open and visible nailing with Sealant K-36 or equivalent repair compound for bitumen waterproofing.
• For mechanical fastening and especially the use of a nail gun, ensure that the nailing is done straight down and with the correct pressure on the substrate, so optimal tightness is achieved against the substrate for the nail head.
• 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 sure to gently load the surface and immediately repair any damage with sealing tape Roofseal-T, roofing adhesive Tätklister K-36, or equivalent repair compound for bitumen waterproofing. For larger damage, use and attach/glue a strip from the underlay fabric.
• Mechanical fastening (visible or hidden) should be hot-dip galvanized roofing felt nails min 25 x 2.5 mm or hidden fastening double with staples corresponding to at least Rapid 140/10 or with larger staples, leg length 12-15 mm, back width 12.4-15 mm and wire dimension 0.5 x 1.3 mm.
• Always cover with the surface layer (roofing felt, welded waterproofing membrane, or shingles) as soon as possible to avoid exposure to sunlight and adverse weather conditions. During construction, the underlayment can be exposed to sunlight for up to a maximum of three months. In the usage stage, the underlayment should 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 YEM 1000 is diffusion-tight and when mounted on a wooden substrate, the space underneath should be ventilated according to practice.
