Troubles With Asphalt Roofing 2, The Self-adhesive Shingles

Very often, the asphalt roofing problems appear if the roofers (usually DIYs) over-estimate the adhesivity of the self-adhesive strips of the asphalt shingles.

The asphalt shingles with the self-adhesive strips

These self-adhesive strips are special adhesive surfaces provided by the shingles manufacturers to help to stick one asphalt pattern to another and many people think they work well and cause seamless joining of particular asphalt shingles and so the homogenization of the whole roofing.

Unfortunately these people are wrong. The self-adhesive points are made of special resin that provides very high tenacity and adhesiveness when treated properly. Such surface sticks to (almost) any other surface or to itself very well.

Using the self-adhesive roofing shingles

When using the self-adhesive shingles we should always consider at least 2 parameters that influence the final quality of such roof.

The first one is the roof slope as the self-adhesive stripes work better with the low surfaces, where the weight of the asphalt patterns does not cause they slide off the roof.

The second parameter is the temperature as the special sticky resine is activated by higher temperature.

Therefore the roofers installing the asphalt shingles with self-adhesive strips should always heat the sticky surfaces with the hot-air heating guns and ensure the surfaces that should be sticked one to another reamin in firm contact unless the shingles are cooled again to the temperature of the environment.
