How Much Does A Roof Restoration Cost?

If you’re planning a renovation or to sell your home, restoring your roof will not only add value to your property but enhance its street appeal. If your roof needs some tender loving care, a roof restoration can be a better choice than a complete roof replacement and extend the life of your roof without the huge cost. In this article, we will cover the signs that will indicate that you need to restore your roof, and the different types of roof restoration, and how much a roof restoration costs.

What is a Roof Restoration?

The process of restoring a roof typically involves cleaning, repairing, and repainting. This is designed to extend the life of your roof, while usually being a cheaper option compared to a full roof replacement.

A roof restoration is different from a repair or a replacement. For starters, a repair is usually cheaper than a restoration as it typically involves fixing a small problem with the roof, for example repairing a leak. A roof replacement is generally the most expensive option, as it involves removing an existing roof and replacing it with a new one. 

What Are The Signs You Need Roof Restoration?

Roof Leaks

Your first indication that your roof needs restoration will likely be that your roof has frequent leaks. If the interior of your home has been compromised, you may discover dark spots of mould or rot growing on your ceiling, or trails of moisture on your ceiling. These suggest water damage from a roof leak.

Life Expectancy

Generally, most roofs will last for 20 to 25 years, although this lifespan varies depending on the material used to construct your roof. If your roof has reached the end of its life, restoring your roof once will be less expensive than paying for frequent repairs.

Roof Sagging

A sagging area in the roof is a sure sign of roof damage. If you notice that there is a visible dip in your roof, chances are you have a problem with your roof rafters.

Deteriorating Roof Valleys

Damaged roof valleys require fixing as soon as possible. If you notice worn or loose material around the chimney, vents, pipes, and other areas where the roof has been penetrated and sealed, this is a sign your roof needs attention as soon as possible.


Corrosion, also known as rust, is a strong indication that water is collecting around your roof’s fittings and fasteners. If you detect rust alongside flaking paint and rotting timber, it’s best to have your roof professionally inspected to evaluate the level of damage.

Mould, Rot, or Moisture

Mould On Roof

Unlike algae and moss — which, in their proper settings, are healthy, natural flora — mould is a real health risk for your family, especially black mould like what you see pictured above which is highly toxic. Mould is easy to spot due to its rancid smell and slimy, unattractive appearance, which is characterised by black, brown, and dark-green blotches.

Damaged Gutters and Downpipes

It’s easy for owners to overlook damage to their gutters and downpipes. If your roof’s gutters and downpipes show rust or corrosion, this is another sign your roof needs attention.

Cracked Or Worn Roof Flashing

If your roof’s tar or cement flashing looks cracked, broken, or worn, it may be best to have your flashing replaced with modern metal flashing, which will prevent leaks and delay the need for premature roof restoration or replacement.

Cracked Or Broken Tiles

Any cracked or broken tiles will need to be replaced as soon as possible. Tile roofing is very durable and rarely needs to be completely replaced. However, if you overlook individual damaged tiles, water can seep in and cause the timber holding up your roof to rot, leading to a more expensive roof replacement or restoration.

What is involved in a roof restoration?

Depending on the type of roofing you have, this will typically involve replacing tiles or sealing and repainting the metal sheeting/Colorbond – or replacing these elements entirely. Initially, the roofing specialist will pressure clean the roof to remove all the dirt, mould, and algae. They will then remove and replace old ridgecaps, mortar and pointing material.

Metal roof restoration

Metal roof repair involves either patching a spot leak or replacing an entire sheet of roof sheeting. Leaks often develop at the seams or where the roofing joins flashing or guttering

A patch is usually utilised to cover a localised leak in a metal roof and is from the same metal or colourbond of the original roofing. Metal screws are used to affix the patch and then sealed to prevent any further leakage.

Roof tile restoration

Roof tile replacement of a faulty roof tile can avoid serious structural damage to your home and potentially costly repairs. Roof tiles can crack or be damaged by several factors, including severe weather and falling tree branches. 

Any necessary repairs are then made, such as rebedding and repointing the ridge tiles, or replacing broken, damaged, or cracked tiles. This is then followed by the application of an anti-fungicide and sealer.

How much does a roof restoration cost?

At Top Glaze we’ve done over 10,000 roof restorations since we started operating in 1987 and have pretty much seen it all in terms of different types of roofing and different types of damage.

The cost of a roof restoration can vary dramatically based on how old and damaged your roof is and the only way for us to give you a solid estimate of the cost of a roof restoration is for you to book in a FREE inspection with us.

During your free inspection we’ll inspect every part of your roof, assess the issues your roof has and give you an upfront free quote, so you know exactly what the investment will be before any work begins.

The Kind of Restoration

Concrete Roofing

As it is made up of water, sand, and cement, a concrete roof is expected to last for at least two decades, especially when proper and thorough maintenance is done on a regular basis. 

Terracotta Roofing

Terracotta roofing tiles were the only choice roofing tiles in Melbourne before cement tiles were even invented. Terracotta tiles are a more expensive alternative to cement tiles and generally outlast the life of a cement tile so they still remain a popular choice for homeowners who are looking for a high quality option. 

Metal Roofing

It is less common to spot a metallic roof, but the restoration cost is much like that of the exquisite Terracotta tiles. However, it is energy efficient and perhaps suitable for harsh locations.

Factors that Influence the Cost of Roof Restoration

Access difficulties and the scope of work are a few of the common factors that determine roof restoration prices. Read the following aspects to help you define your requirements and allocate your roofing expenses.

Roof condition

The condition of your roof is the major factor that affects your roof restoration cost. When you book in a FREE inspection with our team will inspect every inch of your roof to assess the extent of the damage and work required and give you a fixed price quote.

Bedding and pointing

The type of bedding and pointing your roof uses can also add to your expenses. The price of basic mortar bedding may differ from polymer bedding. Likewise, the cost of repointing roof ridge tiles may vary from the standard labour rate of repointing metal roofs.

Size of your roof

The average-sized roof in metropolitan Melbourne is between 120 m² – 220 m². Keep in mind your roof size will be bigger than your house due to overhang and pitch.

Roof type

Metal roof restoration jobs may require a different process unlike with tiled roofs. Age-old metal roofs may need to be resealed or repainted to resolve aesthetic concerns. In some cases, replacing the entire sheet is necessary to avoid further leaks or damage.

Additional charges

In some cases, large repairs are required to restore the look and functionality of your roof. This may mean spending extra for labour and materials. Replacement jobs also influence the cost of roof restoration services.

It’s often a good idea to get a couple of quotes from different roof restoration companies or contractors. When doing so, make sure you outline what needs to be done and describe your roof in as much detail as possible.

When do you need a roof replacement?

If you’re unsure whether your roof needs restoration or a replacement, then it’s a good idea to get our team to inspect your roof, and we’ll be able to let you know whether you just need roof repair work, a full roof restoration or a roof replacement.

A lot of the time, some of the very older tiled roofs are not worth restoring because, for example, certain designs are less capable of keeping moisture out.

We also generally recommend replacing rather than restoring sheet metal roofs because a good quality sheet metal replacement can last you 40 years. In contrast, a restoration is only as good as the paint you’re putting on it.

How long does a roof restoration take?

You’ll need to allow around three to 10 working days for a roof restoration. The exact time it takes to restore your roof may vary depending on factors like what repairs are required, the size of the roof, and the weather. 

Restoring Your Roof To “Good As New” Condition

Replacing All Damaged And Broken Tiles

The first thing we’ll generally do is replace all damaged and broken tiles on your roof to prevent any further leaks or damage.


Man Cleaning Roof

Next we pressure clean your roof to remove all debris, moss, lichen, dirt and grime.

Replacing Valley Irons

Valley irons carry water to your gutters and in most roof restorations we’ll replace them too.

Replacing Old Ridgecaps, Mortar and Pointing Material

Next we’ll replace ridgecaps, mortar and pointing material.

How long does a roof restoration last?

You can expect a roof restoration to last for approximately 15-20 years depending on the environmental factors. Additionally, paint manufacturers will typically give a warranty for the paint used, which can often be for 10 years or more. When seeking out roof restoration quotes, consider double-checking what warranties apply and what you will and won’t be covered for.

Questions To Ask When Hiring A Roof Restoration Company

When hiring a roof restorer, it’s important to make sure they’re right for the job. Some questions to ask include:

  • Are you licensed?
  • Do you have valid insurance?
  • Can you provide a written quote?
  • How long is the warranty on your materials?
  • Do you have any references I can follow up on?
  • No matter the size of your roofing job, always request a fully itemised quote.
