How Temperature Change Affects Your Roof?
By Modern Seal RoofingMay 20, 2021

These weather patterns and fluctuations may result in harm to the roof of your property.

The roof is the most exposed part of the house and, as such, requires care and maintenance for optimal performance. Roofing materials behave differently, but all types can be affected by weather and temperature variations.
The Effects of Weather on your Roof:
Expansion and contraction
Temperature extremes can have long-term effects on roofing materials. In general, cool temperatures cause a roof to contract, whereas hotter temperatures will make it expand.
The heat of the sun causes your roof to stretch. This expansion can result in cracks and fissures forming in the roof’s surface, flashing, window trims, gutters or siding. Heat is not the only culprit; cold weather can also create problems by shrinking the roof material – and the cycle continues.
Colour and Shade
The roof colour you choose could mean the difference between an enjoyable summer and a tough one.
Although black may look sleek and modern, it is not the best colour for a roof in hot temperatures. Black roofs are hotter than white roofs. Not only does the use of lighter coloured roofing material have the potential to cut your cooling costs, but it also looks great. It will help to improve the value and aesthetics of your house.
Darker roof tiles absorb more heat, thereby requiring more use of your air conditioner and, consequently, higher energy bills. You’ll save money by opting for lighter shades when installing or replacing roof tiles.
Temperature expansion is a serious problem that needs to be addressed regularly to prevent the need to replace your existing roof in the future. Every homeowner should be aware of the short and long-term effects of temperature fluctuations and the need for effective expansion joints; a lack of expansion joints is a disaster waiting to happen.
Other Seasonal Changes
Melbourne’s weather changes constantly. It certainly is the city of ‘four seasons in one day. Extremes of temperature can result in your roof aging much faster than it would in more temperate climates.
Thermal shock is the cause of this damage. Temperature fluctuations can affect your roof’s overall health and longevity because the roofing materials behave differently during warmer and colder months. This pressure placed on your roof is called thermal stress.
It’s essential to have your roof checked over by professional roof restoration experts.. They will check for existing and potential problems caused by the effects of thermal shock.
The Cumulative Effect
If you live in an area with warm summers and cold winters, your property’s roof will continually expand and contract. This movement may result in failing nails, loose brackets and warped or cracked flashing and roof materials.
