GENERAL CONDITIONS MATERIAL REQUIREMENTS • IKO assumes no responsibility for leaks due to improper application, or failure to properly prepare the roof surface. Shingles may not be installed directly over insulation; flow-through ventilated air space must be provided between the insulation and the nailable deck. • Shingles: IKO’s selection of more than 70 different types and colours of fibreglass based oxidised and APP modified bitumen shingles. • Do not mix different production dates/codes on the same roof surface. • Underlays: IKO Armourbase: a range of watertight roofing membranes. • Colour...

ROOF PREPARATION The roof deck must be smooth, firm, dry and securely fastened. The deck should be made of good quality plywood, sheathing boards or nonveneer structural panels (wafer or strand board). Wooden boards can be maximum 15 cm wide. The thickness of the deck depends on the span between the beams. Check your local building code regulations. All wood products must be properly conditioned to be at moisture equilibrium. Decking should be installed in a staggered manner and sufficiently supported. Failure to use proper decking material, which can provide a rigid deck surface, can result...

Attention: For low slope valleys use IKO Base for underlayment in the valley. This underlayment must be applied with good mechanical fastening (nails or screws every 20 cm in all directions). Afterwards the IKO Armourvalley must be fully torched on it. • Woven or Closed Cut Valley Preparation (Figure 8e, 8f) Prepare the valley with one layer of IKO Armourbase Stick adhesive underlay with 30 cm laps. Alternatively, use a layer of IKO Armourbase Pro, Pro Plus or Eco or an approved shingle underlay, nailed 2,5 cm from the edge. Laps should be 30 cm and glued. V. EAVES PROTECTION (Figure 4c) In climates...

Attention: When applying laminated shingles, trim off 25, 50, 75 ... cm respectively from the left end of the first shingle in the second (5), the third (6) , the fourth (7), ... course. Note that other offsets between 10 - 25 cm are permitted. For Cambridge Xpress and Cambridge Xtreme 9,5° to obtain a 3D-effect apply capping shingles by stacking 2 pieces on top of one another (slightly offsetting the shingles by 2,5 cm in exposure).
