Is it Better to Replace or Repair a Roof in Sydney?

by admin

Roofs are essential to any building as a protective barrier from the sun, wind, rain and snow. However, with time and external pressures, the tiles or slates can suffer leaks, pest infestations and mould. In extreme cases, the structure may collapse if left unattended for too long, causing significant damage to property and life. This article discusses deciding between roof replacement and roof repair in Sydney. Read on to learn more.

What does roof repair involve? 

Repairing a roof usually involves little material and labour and targets minor, isolated damage. For example, a couple of damaged or missing shingles, discolourations or minor leaks. When inspecting your roof, scan the structure (maybe from across the street) for visibly broken or missing shingles, holes and cracked flashing. On the other hand, consider calling a professional roofing contractor for an inspection. Most companies offer this service for free.


  • Affordable in terms of material and labour; 

  • Significantly lower downtime and timely operations;


  • Discrepancies in colours and shades; 

  • May mask underlying problems

What does roof replacement involve? 

Replacing a roof usually means swapping the visible area with new roofing materials. The process may involve repairs if, during removal, damage to the sheathing, rafters and trusses becomes apparent. Furthermore, a roof replacement usually requires more materials, labour and time than repair and, therefore, a higher price tag. Sagging, constant leaks during rain and drafts in the winter are signs that a roof replacement is in order. However, if you use shingles for the roofing and have no more than a single layer installed, you could consider re-roofing, but that is a story for another day.


  • Comprehensive approach; 

  • Long-term savings; 

  • Longer lasting solution.


  • Costly in materials, time and labour; 

  • More risk of downtime; 

  • More dangerous.

How to decide between roof replacement and repair 

Before you decide whether to opt for roof repair in Sydney or replacement, consider the following factors. 

The size of the affected area 

As mentioned, widespread damage means you should consider replacing the tiles, shingles or plates (depending on the material used). On the other hand, isolated damage limited to a small space can be patched. Generally, if the affected area exceeds a third of the total area, consider replacement over repair.

General condition and state of affairs 

If the rooftop looks old and weather-beaten, but there is no evidence of damage, re-roofing or a new paint job might do the trick. However, if you’ve already had your roof repaired several times, get a professional to inspect the rooftop and consider a replacement.

The roof’s age 

Most roofing material is designed to last anywhere between ten to twenty years. If your roof is on the tail end of that spectrum, you’re probably due for a replacement. For example, barring extreme weather, asphalt roofing shingles typically last two decades, give or take a year. On the other hand, clay roof tiles can last up to thirty years, and metal roofing has an average lifespan beyond forty years.

In conclusion, now that you better understand the dynamics of roof repair in Sydney, you should be able to quickly assess your rooftop’s condition. However, bear in mind that nothing beats a professional opinion. So consider engaging local, qualified roofing specialists to conduct a free inspection. For example, contractors like My Slate Roofing can quickly identify the roof’s actual condition and suggest tailored solutions.
