On all pitches, IKO recommends that an underlayment must be used underneath the roof shingles.

IKO Armourbase STICK underlayment with superb self adhesive properties in combination with its extreme lightness (only 450 g/ m²) favours the application in comparison with other thicker and heavier underlayments. It is the top product underlayment in the range.

Application instructions

Install as flat as possible to prevent unevenness from being projected in the shingle surface. Install parallel to the eaves.

Slopes 9,5°- 20°:
it is advised to cover the entire roof deck with IKO Armourbase STICK adhesive underlay which will seal the entire deck. End laps must be 15 cm and horizontal laps 10 cm.

Slopes 21°- 85°
The entire roof deck should be covered with IKO Armourbase 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.
