You can usually diagnose that you need a roof repair carried out because either light or rainwater is getting through it — something that means trouble could be in store. Thankfully, many professional roofing contractors all over Australia deal with repair work as well as installing new roofs on housing developments. If you think that you might need a repair, then call out a roofer to make an inspection for you. In the meantime, what are the main reasons that you may require a roof repair in the first place? Read on to find out the four most common reasons.

1. Poor Installation

Even though there are plenty of good roofing installers in the country, some work is not carried out the standard that it should be. On commercial buildings, the roofing system may be under a warranty, but this won't always help you if it has been fitted improperly. Get a professional to put right any issues with a poorly installed roof before the problem worsens and your warranty is invalidated.

2. Wind Damage

This is quite a big deal in Australia, especially in exposed locations and settlements that are close to the coast. That said, damage caused by strong winds can occur anywhere in the country. Typical problems are that felt roofs become ripped or tiled roofs start to have elements that become dislodged. Corrugated roofs are particularly susceptible to wind damage, so have them repaired as a priority if you've suffered from high winds recently.

3. Sunlight Exposure

Although roofs are designed to be out in the baking sun all day long, they will not last forever. This is especially the case where there are high levels of UV light. UV light deteriorates many materials over time and can be particularly bad with flat roof composites. A roof repair for sunlight exposure might not be very expensive, however. Sometimes a coat of paint is all that is needed to bring it back to a good standard.

4. Ice Damage

Depending on where you live in the country, you may have never experienced ice on your roof. However, in the south, low temperatures may cause your roof shingles to expand and contract. If water freezes between them suddenly, then this can expand just as the roofing elements are contracting which forces them out of position. Once the ice melts, tiles and shingles can be left out of kilter with one another which, consequently, allows rainwater to work its way inside.
