In every Australian residence, maintaining your house is key to minimising short- and long-term costs related to any home repairs and improvement. This is particularly the case for complex jobs like reroofing. For this matter, one of the most critical decisions you’ll ever make is whether you will have a roof repair or full roof replacement Sydney service.
Would you rather patch leaks and damaged areas or is a complete re-roofing service in order? There are cost consequences either way, but your decision should be based on several factors, which we will discuss further in this article.
Should you Repair or Replace Your Roof?
In some cases, replacing a few shingles is all it takes to restore beauty and function to your roof. Asphalt shingles are designed to last for decades and if a section is damaged or deteriorating, you can opt to roof over the existing shingles instead of replacing the entire thing.
Patching damaged areas is a relatively easy and cheaper route. It is applicable if you have just a few damaged or missing shingles. You are also a candidate for re-roofing if you only have one layer of shingles on your roof. Roofs that already have two layers of shingles in place are not allowed by building codes to install a third layer. In this case, a full roof replacement should be in order.
The only downside to re-roofing is that even if you have spare shingles that are leftover from your roof installation, they may not precisely match the rest of the roof as the existing shingles are already subjected to weathering. It’s why many roofing contractors mostly recommend this method if the damaged shingles are located in an inconspicuous area.
With all these said, just when is it better to have your roof completely replaced? There are factors to keep in mind.
Age: Most roofing systems in Sydney have a 20-year warranty and if your roof is near or past its useful years, replacing the entire roof may be the way to go.
Materials: Besides age, the material your roofing is made with dictates when you should replace your roof. For example, asphalt shingles are made to last up to 50 years, provided that it’s well-maintained, whereas a metal roof in its fifth decade is well past its useful time.
Extent of Damage: Patching is for roof damage in a small area. But, if the damage covers at least 30% of the roof, you should consider a full replacement.
Cost: If the cost of re-roofing is more than or nearly the same as the cost of roof replacement, then the latter is a better value.
Underlying Issues: Are there signs of moisture damage to your roof deck? If so, roofing over them will not solve the problem. Roof replacement plus addressing leaks and water damage is likely your best option.
Aside from these factors you should consider, there are also visible signs that would indicate it’s time to replace your roof.
Curling and Buckling Shingles – Look at the slopes of your roof that get direct sunlight. If you notice that the shingles are curling, it could mean they are past their useful life. This could also indicate that the roof is defective.
Missing Shingles on Roof Valleys – A valley is formed where two roof slopes meet. It’s what directs melted snow and rainwater into gutters. Therefore, if it’s compromised, your roof could be susceptible to leaks.
Granules in the Gutters – Roofs have the tendency to lose more granules toward the end of their lifespan. You would notice it when you see your gutters loaded up with shingle granules or when your roof has inconsistent colour.
There are many other signs of roof damage to keep an eye out on. But, working with your local roofing contractor in Sydney would help you determine whether re-roofing would do or a replacement should be in order.
A roof inspector would help you assess your roof and check for missing shingles, leaks, holes, rot, water damage, mould growth, and even clogging. Schedule a roofing consultation today!
