How Temperature Change Affects
Your Roof?
Melbourne is well known for its notoriously
fickle weather. With an average yearly
temperature of 15C, Summer days can reach the
mid-40s, and Winter can sometimes be below
freezing. 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 roofs 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. Youll save
  money by opting for lighter shades when
  installing or replacing roof tiles.

• Expansion Joints
• 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
• Melbournes 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 roofs
  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.
• Its 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 propertys roof will
  continually expand and contract. This movement
  may result in failing nails, loose brackets and
  warped or cracked flashing and roof materials.
• Modern Seal Roofing fixes all roofing problems
  faced by homeowners as a result of weather and
  normal wear and tear.
