Long, hot summer: Can the sun damage my roof? by Kathy Slencak

Can the sun damage my roof? That’s an interesting and complex question. Do you know that there are both beneficial and detrimental aspects of sunlight and its effect on your roof?

On the positive side, the sun can help provide light for interior spaces through prismatic skylights, create a more natural work environment and save significantly on energy costs. The sun can also serve to reduce costs and may provide an actual income stream through photovoltaic solar systems on a roof.

However, the sun is one of the harshest elements of nature that affects a roof. Hot, dry weather can crack a roofing membrane (known as alligatoring) which can result in roof leaks once it does rain. Don’t think dry weather means your roof is OK.

The sun’s intensity and related heat can cause roof membranes and flashings to fail prematurely. Even roof systems utilizing white reflective membranes have experienced problems due to exposure to the sun and heat loads. Asphalt-based roofs, when exposed to the sun and any standing water, may result in the light oils leaching from the waterproofing bitumen and cause premature failure.

These are reasons why routine inspections and preventative maintenance programs are keys to preventing roof failure.

After summer months of extreme high temperatures, strong pop-up storms and high winds, these weather patterns can also bring roof damage that can cause headaches with the onset of autumn and winter! Be proactive and minimize future roofing problems by taking advantage of fall preventative maintenance programs. By addressing any concerns in the Fall, you are preparing your roof for the predicted harsh winter weather.

A Fall to-do list for your roof with your roofing contractor:

• Schedule a roof inspection: Check for roof leaks, debris on roof, existing or potential roof problems;

• For white TPO roofs, schedule a roof cleaning of the dirt, grime, algae and mold;

• Review your preventative maintenance needs as outlined on your roof warranty; and

• Plan your roofing budget for 2017 with your roofing contractor.
