The entire roof deck should be covered with IKO Armourbase GO underlay or an approved shingle underlay. The underlay should be installed parallel to the eaves with a min. 10 cm horizontal lap and 15 cm end laps. On all IKO Armourbase underlayments there are 10 cm lines on the rolls for easier overlapping. Secure the underlay with only enough nails to hold it in place.
