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 PLUS) 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.
How to install shingles on very steep slopes or vertical walls
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.
If a roof slope is from 60° - 90° degrees, IKO Cambridge Xtreme 9,5° should be applied by the following recommended method:
- The roof deck for IKO Cambridge Xtreme 9,5° can be made from Plywood, OSB or sheathing boards;
- Plywood or OSB shall be exterior grade and wooden boards must be maximum 15 cm wide. The roof deck must be smooth, dry and free from warped surfaces;
- Remember that plywood or OSB boards are always recommended for very low or very steep slopes!
- Use IKO Armourbase underlay for slopes between 60° and 85° degrees;
- For slopes from 85° - 90° degrees (vertical wall) an underlay is not required but recommended.
