How Much Does a Roof Repair Cost? (And Factors That Affect the Cost)

Roofing problems can easily go undetected until they become more serious and costlier to fix, so regular checks should be carried out to detect faults early and avoid high roofing costs. However, if you are considering replacing a roof, then things have probably progressed way beyond minor repairs.

You may need to replace your roof if you notice a leak in the ceiling or attic. This could include everything from watermarks to damp patches and mould, which could be signs of water damage in the upper storeys of your home. More severe water damage could present as sagging or bowed parts of the roof internally. At this stage, not only will you need expensive roofing work, but you could also require a joiner to replace the ceiling, plus a plasterer and/or interior decorator to repair the water damage inside your home.

Other clear signs that you need your roof replacing include escaping light, debris in gutters, or even falling mortar from a broken chimney. These faults are not only dangerous but may also require further work such as repointing the chimney, replacing the gutters and adding insulation.

If you have not checked your roof for several years, you may even notice a process of rotting which may have spread to your inner walls.

You should also try to keep track of ageing materials, as some age quicker than others. The table below sets out the different types of materials and their lifespans:

Roof area

The roof area determines how many tiles are needed for square metres, and how long it would take for roof tilers to work on your roof. Consider this major factor when calculating your tile roof cost.

What Is The Cost Of Painting A Colorbond Roof

The cost of professionally painting a Colorbond roof ranges from $50 to $70 an hour inclusive of GST. Your roof painter will also charge for any necessary prep work and cleaning.

Why does painting Colorbond cost up to $70 an hour? First, the painter washes the surfaces to be painted with water and detergent followed by a rinse with clean water to remove any residues, grease, or dirt that may have accumulated on the steel.

Then the painter needs to sand the Colorbond to ensure good adhesion of the paint. This step does not remove the protective zinc coating added to the Colorbond at the factory, because the heat in the galvanizing vat, about 425° C, is hot enough that the zinc and steel form a layer of alloy that goes into the steel itself. It only takes a little scuffing up of the baked-on paint on the Colorbond to ensure good adhesion of the new coat of paint.

Depending on what paint is used to paint your Colorbond, the painter may need to apply a primer, or just use a single coat of a self-priming acrylic. Then the painter applies top coats.

How Long Can I Expect My Roof Restoration To Last

How much does a new roof cost

Generally, a quality roof restoration will last between ten and 15 years, and additionally, paint manufacturers will typically give a warranty, which is at least ten years. After that time, the roof coating should still remain on tiles, and the ridge capping only needs repointing.

Over time, the roof paint will fade, and the glaze will erode. However, as long as the coating remains on the tiles, they should be protected to an extent. Once the glaze has deteriorated, the coating underneath oxidises and becomes very chalky. The oxidised coating must be removed, along with the dirt and grit on the surface and in the craters and pores of the tiles.

Ridge capping generally lasts ten years, however, eventually the mortar will begin to break down, resulting in cracks. This is when leaks may occur, along with other roof-related issues. If you put off re-pointing, you will eventually need your ridge capping re-bedding, which is much more costly than re-pointing. When a roofs ridge capping is rebedded, the old mortar is removed, and the ridge caps are reset.

Consider Installing An Overlay

A roofing overlay is an alternative to roof replacement when there is a limited budget. This option applies only if you have not installed an overlay before. An overlay involves installing new singles on the top of the existing ones. This way you get to keep your old roof and reduce spend, as overlaying takes fewer labour hours.

A word of caution about overlays as they are not always the best solution. New singles tend to last less than the manufacturers warranty due to extra heat trapped by the added layers. You add extra weight to your roof endangering the structural integrity of your house. Furthermore, overlays do not always look that great, make it difficult to inspect the condition of the deck when reroofing and also reduce resale value.

Optional And Compulsory Add Ons

To comply with current building regulations, if you replace more than 50% of your roof covering, you must also upgrade your existing roof insulation to meet current building requirements.

The cheapest and quickest way to achieve this is to install extra loft insulation placed directly above the ceiling. This page reveals how much loft insulation costs.

We already provided a price guide for replacement roofline boards, but bear in mind that its cheaper to replace them at the same time as your roof than having to put scaffold up again and doing the work as a separate project.

While the scaffold is up you should also consider re-pointing chimneys. The cost of chimney repointing is cheap and most of the price is swallowed up in scaffold costs.

Building control notification fees vary from council to council. Also, if your chosen contractor is part of the Competent Roofer scheme, they can notify building control for a small nominal fee, this is because scheme members are able to self-certify their work as part.

Unregistered roofing contractors can still notify building control about the roof work but at extra cost. The price is different for each council but you can expect to pay £200-450 per notification.
