What nails to use for installing roof shingles?
Other features are:
- the little bulk of each roll allows operator to carry more rolls during handlings and transports
- despite its lightness it shows good waterproofing properties (it is W1 ranked and has average values of 4 m in the water column test): thanks to the particular bituminous compound able to enhance its waterproofing behaviour
- it has a very valuable resistance to cold (up to - 45 °C!!!) allows it to resist also in extreme cold weather conditions
- the total adhesion on the continuous support protect it from external atmospheric agents
- application lines on the surface make the application more easy and precise
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.
IKO ventilation on your roof offers quite some benefits:
- Extend the life of your roof and of your shingles
- Increase your living comfort
- Regulate the moisture in your roof
- Allow excess heat and water vapour to escape from the roof
- Allow air to circulate between insulation and roof deck
- Prevent humidity from damaging the roof construction
- Cool down the roof in hot weather conditions
- Prevents ice-dams after snow
Application instructions
It is essential to allow heat dissipation and water vapour to escape the roof system through proper ventilation. Therefore, air must be able to circulate freely between insulation and the nailable roof deck, from the eaves to the ridges.
On roof pitches 15°- 40° the minimum net free ventilation area is 33 cm²,
on 41°- 85° min. net free ventilation area is 16 cm² for each 1 m² of insulated ceiling area (P),
always divided evenly between the eaves and the ridge.
