  • Use the correct IKO roofing nails;
  • Secure every shingle of IKO Cambridge Xtreme 9,5° with 6 nails in the nailing zone;
  • Drive the nails straight so that the nail heads are flush with the shingle and not cutting into the shingle surface;
  • Remember: proper fastening is essential for a good roof!
  • During cold weather the application of extra mastic must be added in the same manner;
  • Apply only a thin, linear, uniform layer of asphalt mastic less than 3 mm thick and 25 mm up from the bottom of the shingle;
  • Excess amounts can cause blistering and sticking of the shingles!
  • Remember: application on vertical walls and façades is always better during warm weather when self-adhesive bitumen glue is more effective!
  • There might be an unvented space behind a mansard roof or vertical wall. It is important to provide a properly ventilated flow-through air space behind the roof sheathing to prevent the entrapment of moisture-laden air;
  • Therefore, air must be able to circulate freely between the insulation and the nailable roof deck
  • Proper ventilation is crucial to extend the life of the shingle roof;
  • For steep slopes and façades it’s ideal to create the required ventilation with IKO Armourvent Multi;
  • Most major building regulations require a minimum ventilation ratio of 1 m² net ventilating area per 300 m² of attic floor space (1:300). For steep slopes and façades 1 m² net ventilating area per 600 m² (1:600) is enough. It is always divided evenly between the eaves and the top of vertical wall;
  • Remember: the air gap between the insulation and the roof deck must be 4 to 6 cm;

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.

A question we get a lot is if it is possible to install skylights or roof windows in a shingles roof? The answer is simple: Yes! In this blog we’ll show you the steps how to install a skylight, but let’s talk skylights first!

Roof windows and skylights are very simple concepts with a lot of advantages. They are primarily bringing natural light to the attic and living space. This is perhaps the most important advantage, as sunlight is beneficial to our health, tone and mood. Adding a skylight will allow people to live more comfortably in relation to their biological clock.

A second advantage is using natural light in your rooms and lowering the bills for electricity. Installing a vented skylight solves the problem of insufficient ventilation and lets the air move more freely and naturally, creating a fresher home aroma.  The ideal place to install a skylight is a kitchen, bathroom or bedroom. This ventilation advantage also means saving electricity, as there is no need for you to use a kitchen or a bathroom fan.

Privacy can be another advantage as well. Often houses are located side by side and opening a window opposite to another window is not always convenient. Roof windows can bring natural light to your bathroom or bedroom, without sacrificing your privacy. 

Types of skylights and roof windows

There are three basic types of skylights: fixed skylights, venting skylights, and tubular skylights (light tubes). A fourth variety, roof windows, is a type of venting skylight used where circumstances make it practical. Roof windows are bigger with the same orientation as the surrounding roof. They are typically used on roofs where the roof slope is more vertical.
