Option 2: use an IKO Armourbase Pro or ECO underlay or a similar base sheet, to provide a double coverage of underlay to the roof deck. Cut a starter strip 50 cm wide and lay succeeding courses fastened with 50 cm horizontal laps and 30 cm end laps.

Slopes 21°- 85°

The entire roof deck should be covered with an 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 IKO Armourbase Pro, - Pro Plus, - Stick and - ECO there are 10 cm lines on the rolls for easier overlapping. Secure the underlay with only enough nails to hold it in place.

Slopes 85°- 90°

No underlay required. Only self-adhesive shingles such as Cambridge Xtreme 9,5° or ArmourShield PLUS can be applied.

Underlayment failure

Some underlayments may fail for a number of reasons:

Poor quality

Poor quality underlayments absorb more water. Water absorption can cause wrinkling as the product expands. These wrinkles may telegraph through to the roof covering products, such as thinner bitumen shingles. Underlayment as felt paper is not recommended to apply over roof decking. Water and moisture from a wet underlayment may be absorbed by the roof deck, which can cause problems with expansion and contraction of the deck. The typical result of this failure is wrinkled shingles.

Style 3: Wonderful Warm

Our laminated shingles are the ideal material to effortlessly blend rustic and modern elements. Take a look at our colours Earthtone Cedar (49), Riviera Red (55) and Autumn Brown (53). Even though they can easily be used in modern architecture, they also suit as a replacement for those rustic wooden tiles.

Combined with some ocher yellow, taupe or brown, you will be able to create a warm and intimate atmosphere for your house in no time.

Request an A4 sample of one of our natural, warm colours to see how well it suits your home.

Riviera Red (55) is bold red that is warm and dynamic, which combined with even a neutral beige, can bring immediate warmth to your home.

Or our Aged Redwood (54) brings a impressive look to the classic architecture beneath. As you can see, the possibilities are plenty in making a warm and cosy look for your home.
