Have you heard the term “thermal shock” in reference to metal roofing, but don’t know what it means, what causes it or what to do about it?
In this article, our experts provide you with all the information you need, from how thermal shock is defined, what you need to look out for and what to do about it, including when to call our experts at Manchester Roofing.
Thermal Shock: A Definition
Thermal shock is the damage left behind after a sudden rise or drop in temperature has caused it to expand or contract too quickly. Among other areas, you may experience damage to the metal roofing itself, the membrane, flashing, shingles and insulation.
What Happens if Thermal Shock is Left Untreated?
Thermal shock can cause severe problems to your roofing, as the disintegration of certain areas of the roof can leave it exposed. Just some of the issues you could be facing when your roof has this kind of damage includes:
– repairs to existing roofing components
– water leaks or problems by exposure to the weather
– rotting wood, beams and joists
– ceiling damage
– fire hazards
Is Thermal Shock Preventable?
Every roof ages, and will experience sudden drops (or rises) in temperatures over time. There is, unfortunately, no way to prevent that. But there is a way you can prolong the life of your metal roofing, and limit the effects of thermal shock.
Preventative maintenance – ensuring your roof is regularly cleaned and maintained – is one way you can help reduce your chances of thermal shock, and the negative effects of ageing.
This also means keeping on top of any repairs and problems that may turn into major issues, so you’re really prepared for those unexpected fluctuations in temperature.
Signs of Thermal Shock
There are a couple of things that usually indicate your roof may have fallen victim to thermal shock. Here we’ll discuss what you should be on the lookout for:
Buckling occurs when a metal roof heats up and expands. This causes your roofing material to weaken and buckle, which leads to tears or swelling.
Crackling mightn’t seem like much of an issue, but it can be if left untreated. Overexposure or overheating causes the roof to age quicker and the materials to wear sooner than anticipated, which is when you start to experience issues that could cost you time and money.
We’ve talked before about the damage a leaky roof can cause; thermal shock can cause gaps to appear in your roofing in which those leaks can form. From mould to pests, to electrical problems and fire hazards, leaks are something that shouldn’t be ignored so you need to get onto it quickly.
When to Call Manchester Roofing
It is important to note, as we have said many times in previous articles, that working at heights can be an extremely dangerous practice. This is especially the case if you don’t know what you’re doing.
We would only recommend it be completed by a qualified roofing specialist such as those on our committed team at Manchester Roofing.
