Roofs lay exposed to the elements day in, day out, year after year. The changing weather and seasons have a huge impact on roofing materials. This includes freeze-thaw cycles. In fact, these cycles, as well as thermal shock, remain among the leading causes of premature roofing material failure. However, by hiring Delta Rooftop Solutions to conduct roof repairs at your property in Doncaster, Rotherham or the surrounding areas, you can stay head of the worst damage before it becomes too widespread.
In this blog, we examine how freeze-thaw cycles have a negative impact on your roof. As a slow process, this cycle won’t announce itself until significant damage has been done. It remains vital, then, that you have your roof inspected on a semi-regular basis to avoid the most extensive, and expensive, roof repairs.
If you haven’t had your roof examined for some time, please call us on 01709 892 393 or 07772 838 021 to schedule a visit.
To understand the freeze-thaw cycles affecting roofs in Doncaster, Rotherham or any other location, let us first introduce the concept of thermal shock. In short, these ‘shocks’ occur when certain points of an object suffer a rapid change of temperature. In turn, this causes the effected parts of the object to expand more than unaffected areas. We recommend viewing this expansion in terms of strain or stress.
Over a prolonged period, these moments of stress and strain exceed the object’s strength limit, causing a split or crack. If you don’t arrange for the relevant roof repairs, this damage causes the material to fail.
From Doncaster to Rotherham, roofing structures consist of numerous parts in varying materials, such as wood, steel, concrete and much more. We know that everything expands and contracts as it heats up and cools down, respectively. However, these differing materials have their own rates of expansion and contraction.
As such, the temperature fluctuations of summer and winter, of day and night, lead to different levels of thermals shocks throughout the entire roofing system.
The freeze-thaw cycle plays out along similar lines. Over time, moisture can build-up in parts of roofing materials where it shouldn’t. If this water freezes, it expands, pushing apart the material around it. On a cyclical basis, this slowly increases damage, necessitating roof repairs to fix the issue.
Of course, reputable roofing companies like Delta Rooftop Solutions factor thermal shocks into our new roofs and roof repairs. Any new roof should have an optimal performance level for at least 5 to 10 years. After this point, it is widely agreed that roofs slowly depreciate, with the average length for degradation being 39 years.
A scheduled maintenance plan and small-scale roof repairs can help to maximise the performance of your materials. In some cases, such an approach can extend the lifespan of a roof in Doncaster, Rotherham or the surrounding areas by as much as 25 to 30 years.
