10. Reusing old flashing

When replacing an existing roof, the old flashing may look serviceable, but there is always the possibility that it has been punctured or damaged. New flashings are a small component in the cost of a roof replacement. Always install new flashings.

Solution:

If they are free of exposed holes and are not damaged, copper and aluminum flashings are not necessary to change. All others should be replaced.

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.

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.
