When To Get Roof Replacement Done

The Australian climate is as fearsome as it is beautiful. Your roof is your home’s first line of defence against Mother Nature, protecting you from harsh sunlight, strong winds, heavy rain, and damaging hail. Given the daily wear and tear, it’s inevitable that your roof will eventually need to be replaced.

But how do you know if it’s the right time for a roof replacement? With over 100 years and four generations of experience in roofing, we’ve seen it all at Roof & Render SA. Below are seven key indicators that it may be time for a full roof replacement.

1 – Check the Inside of Your Home

One of the first places to look for signs of roof damage is actually inside your home. Inspect your attic or roof cavity for any of the following issues:

Dark spots indicating water damage (which can eventually lead to mould)

Water trails showing where moisture has been entering

Light coming through the roof (which could mean gaps in the roofing material)

If you see any of these signs, it’s crucial to act quickly. Minor damage might only require a repair, but if multiple areas are affected, it may be time for a complete roof replacement.

2 – Inspect the Exterior of Your Roof

For a more thorough inspection, you may need to examine the outside of your roof. If you’re comfortable with a ladder and have someone to hold it steady, look for:

Curled or worn shingles (if you have a shingled roof)

Mould, moisture, rot, or signs of animal nesting

Damaged down-pipes and gutters

Be cautious when walking on the roof, especially if it’s steep. Roof inspections can be risky, and our team at Roof & Render SA has the equipment and expertise to handle this safely. We recommend a professional inspection if there are any concerns.

3 – Noticeable Sagging

Sagging is a serious issue that could indicate structural damage. If your roof is sagging, it’s usually a clear sign that a roof replacement is necessary. Sagging can compromise the strength and safety of your home, so avoid DIY solutions and consult a professional to assess the situation.

4 – Your Roof is Showing Its Age

A roof typically lasts up to 25 years, depending on the materials used and the level of maintenance. As your roof ages, it may require more frequent repairs. If your roof is 12-15 years old and in need of regular maintenance, it might be more cost-effective to replace it entirely.

Replacing your roof can save you money in the long run, as the need for repeated repairs will be eliminated. A good rule of thumb is to plan for a replacement every 20 years to ensure the safety and longevity of your home.

5 – Damaged Roof Flashing

In older homes, roof flashing is often made from tar or cement. These materials can break down over time, causing cracks and leaks. Replacing outdated flashing with durable metal flashing can prevent future water damage. If you notice worn or cracked flashing, it may be time to consider a roof replacement as part of a comprehensive upgrade to ensure your roof remains watertight.

6 – Signs of Corrosion

Corrosion is another common indicator of roof damage, particularly around metal fasteners and fittings. If you spot rust or paint flaking off metal components, or if timber sections show signs of rot, it’s a sign that water is gathering and causing damage.

Corroded metal weakens over time, which can compromise the strength of your roof. A professional roofing company like Roof & Render SA can assess the extent of the corrosion and recommend whether a roof replacement is the best course of action.

7 – Issues with Tiled Roofs

If you have a tiled roof, keep an eye out for broken or cracked tiles. While individual tiles can be replaced, ongoing tile issues could lead to more extensive damage beneath the roof. When water seeps through damaged tiles, it can rot the supporting timber structure.

If you notice frequent tile damage, it may be worth considering a full roof replacement to avoid long-term structural problems.

When to Get a Roof Inspection

We recommend inspecting your roof every six months and arranging a professional inspection every two years or after any major storm. Regular inspections can help catch small issues before they turn into major ones, increasing the lifespan of your roof and keeping your home safe.
