Modern architectural design has changed a lot through recent years, even when we consider typical roof and wall material. Many standard roofing materials can now be installed on both very steep slopes and vertical walls. Nowadays these materials used on roofs and walls, not only have a waterproofing function, they also have an aesthetic importance.
>>> The most commonly used materials are clay tiles, metal tiles, slate or wooden shakes and bitumen shingles. In taking a closer look at bituminous shingles as a roofing material, we can see one of the advantages is that they are very light, which makes them easy to apply on a wide angle from 9.5° up to 90° degrees (i.e. a vertical wall).
One of our most suitable roof shingles is the self-adhesive IKO Cambridge Xtreme 9,5°. Thanks to its usability on extreme slopes (9.5° up to 90°), many architects and designers choose this roofing material for its 3D dimensional look, with imitation of wooden shakes, natural stone and slate, resulting in an exclusive look and feel. The IKO Cambridge Xtreme 9.5° is available in seven natural colors and provides a 30 years warranty on material.
Another IKO shingle suitable for vertical roof installation is the IKO Shield shingle. Available in both a hexagonal (ArmourShield) and triangular (DiamantShield) shape, it is the perfect choice for giving walls an extraordinary look. Available in a wide colour range and applicable on roofs/walls from 15° up to 90°, the perfect solution to make your next project aesthetically pleasing. Take a look at this wonderful home covered in DiamantShield.
A steep slope roof shingle application (including mansards and vertical walls) is becoming a common practice. The maximum slope for standard shingles with wind seal dots or thermo-adhesive dots is 85°. For self-adhesive shingles the maximum slope is 90° which means they can be used in a vertical wall installation.
In these cases the gravitational force acts on shingles totally differently to that of a standard lower sloped roofs. The use of bitumen shingles on slopes greater than 60° degrees require the use of special application methods due to the very steep slopes reducing the effectiveness of factory applied wind seal dots/self-adhesive zone, especially in colder climates and shaded areas.
If standard installation methods are used for bitumen shingles on these steep slopes, problems can occur that are not a result of any weakness or defect in the product, but rather because of ineffective application methods.
Following these instructions will assist you or your roofer in installing the shingles correctly.
Safety first: working on steep slopes can be dangerous, so be sure to always use a safety rope and harness where needed.
Remember : Shingles should seal to the underlying course when the factory applied asphalt sealant is sufficiently warmed by the heat of direct sunlight. When application conditions might limit the effectiveness of the adhesive strip, such as cool weather or in areas subject to high winds or blowing dust, shingle adherence should be ensured through manual sealing by Shingle Stick or Plastal Stick.
These pictures are a few examples of what can go wrong when you don’t follow the recommended application method.
>> Picture 1: Failure of buckled shingles on façade because of movement of the wooden boards!
>> Picture 2: Visible movement of wooden boards and gaps between!
>> Picture 3: Vertical wall application without extra bitumen glue can cause peel off shingles especially with lack of ventilation and movement of the wooden deck!
So be sure to follow the recommended application method, in order to create an impressive end result on your roof and wall. Good luck!
