The summer season and the heat that it brings can wear flat roof systems down. That said, commercial property owners and facilities managers must lead the way in making sure the tops of buildings are well-maintained. Being aware of the ways the sun affect roofs helps prolong their service life and avoid costly repairs.

How the Summer Heat Affects Flat Roof Systems

The Sun’s Intense Heat

Roofs are designed to weather, and, as the years go by, they begin to undergo physical changes due to exposure to the elements. The sun, in particular, has a great impact on their lifespan mainly because of what it brings – thermal shock, heat and ultraviolet (UV) rays.

Even on cool and cloudy days, the surface of flat roofs continues to receive UV exposure. It dries out the roof’s oil components, leading to the loss of its waterproofing qualities. Day-night temperature changes also cause flat roofs to expand and contract, exposing the inner layers to potential leaks and further damage.

Roof Problems Related to the Sun

Roof repair contractors like us are able to determine signs that tell flat roofs are damaged due to intense heat coming from the sun. Blistering, for instance, is characterized by bubble-like protrusions in areas where the surface has lost its adhesion to the roof substrate. It is a result of the expansion and contraction of trapped air or moisture between the layers due to temperature fluctuations.

Such a problem can also become apparent due to improper installation. Accelerated sun damage becomes more pronounced. Lack of pitch and use of inferior structural materials increases the likelihood of pooling water. With the sun heating up the surface, this standing water will soon find its way through any crack or hole, leading to costly repairs.
