Perth homeowners face several roofing problems due to the city's variable climate. Hail damage is common from September to March, with hailstones often the size of golf balls that can crack tiles or dent metal roofs. Clogged valley irons from leaves and debris prevent proper drainage and weaken roof structures. Extreme summer heat also causes roof tiles to dry out and crack over time, leading to leaks during winter. Proper maintenance and high-quality materials are important to prevent weather damage and prolong the life of roofs in Perth.

1. Climate Change and the Roof:
Top Problems of Perth Homeowners
Perth's climate is a natural blend of Mediterranean
and Californian weather. Summer days are graced by
warm sunshine, with a humid breeze blowing from
December to March. Winters are mild and wet, with
the average temperature not falling below 18 degrees
Celsius during the day.
For most people, especially tourists, Perth's climate
offers just the right mix for their holidays. Homeowners,
however, have a different opinion. While locals do
appreciate the pleasant climate in the city, the changing
weather conditions are something they may not look
forward to.
Many homeowners consider the climate as a risk factor in roof problems due to the extreme heat
during summer and severe thunderstorms during winter. As pleasant as the weather may go, it can
also be problematic for structures.
Here are the top thee roofing problems that Perth homeowners experience with the changing weather
conditions:
Hail Damage
Hailstorms occur throughout the year, but these are
more common from September to March. Most of the
hailstones can be as big as a golf ball, causing permanent
indentation to metal roofs, cracking or dislodging roof
tiles, and clogging gutters.

2. Clogged Valley Irons
Leaves, twigs, and other debris clogging up the
valley irons are also main causes of roof
damage. The clogged system prevents the water
from draining properly and causes it to overflow
to other areas of the roof. The water trapped in
the valley weakens the structure, with the
damage seeping through to the ceiling, causing
further problems.
Cracked Tiles
During summer, Perth's temperature can go as high
as 40 degrees Celsius. The extreme heat dries up
the tiles, causing them to crack over time. Come
winter, homeowners may start experiencing leaks
from these cracks. The tiles deteriorate over time,
which affects both the aesthetics and structural
support of the roof.
Proper Roof Maintenance against Changing Weather Conditions
Prevention is the key to ensure the roof stays
protected from weather damage. Roofing experts
always emphasize proper roof maintenance and
inspection to spot problems early on. They also
recommend the use of quality materials during
restorations or installations to prolong the life of the
roofing structure and avoid unnecessary expenses.
