Thanks to their versatility, roof shingles can be used on different roof shapes, going from simple gable roofs to more complex structures with roof valleys. A valley on a shingle roof is the area where two sections of the sloped roof meet, typically forming an inward angle. It is the line or channel formed where two roof planes (the slopes) intersect, usually at a sharp angle. 

Valleys are crucial because they direct rainwater or snow runoff from the roof into the gutters, preventing water from pooling and potentially causing damage to the roof structure. To get the most satisfying result, IKO offers the Armourvalley roll as the solution for an open valley on a shingle roof. 

>>> IKO Armourvalley is a high-quality APP modified roll finished with ceramic-coated granules that perfectly match the colours of IKO roof shingles.

Roof Valley

Importance of a valley on a shingle roof

Every special feature on your roof is a possible risk of leaks or a reduced waterproof characteristic of your roof. When correctly installing IKO Armourvalley, your roof will benefit from the following points:

  1. Water Drainage: Valleys are the areas where two roof slopes meet, and they act as channels to direct rainwater, snow, and debris off the roof. Properly installed valleys help to guide water safely down and away from the roof structure, preventing it from pooling and potentially causing leaks.
  2. Prevention of Water Damage: Without valleys, water can accumulate in the junctions of the roof slopes, leading to increased pressure on the roofing materials. Over time, this can result in water infiltration, which could cause rot, mold, and other forms of damage to the roof deck or interior spaces.
  3. Structural Integrity: Valleys are an essential component for ensuring the roof's structural stability. If they are not properly constructed or maintained, water can penetrate into the roof's substructure, weakening the entire roof system.

Armourvalley, the aesthetic option for your valley

Even though the waterproof characteristic is of course the most important benefit of the IKO Armourvalley, this roll also offers an aesthetic value for your shingle roof. 

Available in 8 different colours, it can be used in all different available shingle ranges: not only the warm basic colours used in the Superglass range, but also the natural colours of the Cambridge Xpress and Xtreme 9,5°. Being able to match your valley with the colours of your shingle will result in a more finished look, contributing to the overall curb appeal of your home.

Armourvalley, more than just a valley

Being a high-end asphalt roll, IKO Armourvalley offers benefits that most other roofing rolls do not provide. Manufactured with APP-modified bitumen, it is designed to withstand harsh winter conditions and extreme heat. In combination with the IKO Base underlayment, Armourvalley can be torched on a flat roof extension, seamlessly connecting to a shingle roof with a standard slope. Being available in a variety of matching shingle colours, it’s an ideal solution for adding features such as an outdoor kitchen, garage, or other extensions to your existing shingle roof.
