Signs that you need a new roof

• Dark patches on ceilings and/or mould and water ingress
• Lead nail heads rolling off the roof and visible signs of rust
• A crinkle sound when walking on roof, especially on short lapped sheets

Re-roofing: What you need to considerRe-roofing is a great time to insulate your roof space, remove asbestos from your roof and clean or clear gutters. It’s also an opportunity to modernise your home, change the colour scheme or give it a completely new look with a contemporary long-run roof. Other considerations include:

Asbestos removalAsbestos is a specialised product to deal with and needs to be removed by an approved contractor. We hold certification issued from DOL (Department of Labour) to conduct asbestos removal.
Re-pitchingYou might also consider re-pitching your roof at this time. You can engage a builder of your choice, or if it is a minor change we can often get one of our roofers to do this while they re-roof your home. With Aaron’s building background he will be able to tell you more about the process.

New Purlins Timber Purlins are what roofs are typically fixed to. Existing purlins are sometimes affected by rot, especially on older and usually leaky roofs that we are replacing or repairing. If our roofers become aware of this when existing roofing is removed, upon discovery of degraded timber we advise the customer, and then our highly skilled roofers will be able to replace it.

Conversions from concrete tile or metal tile to longrun roofing We have done many conversions from both concrete and metal tiles to long run roofing. After completing so many conversions, Riteline Roofing has become somewhat of a specialist in these types of conversion

​Metal Roofs versus Tile Roofs

For years Christchurch utilized tile roofs, and when they first came out were a plausible option for a Christchurch homeowner. Since those times, nature has not been so kind to the clay and concrete tiled roofs. The natural composition of tiled roofs plays a huge factor in their early demise. Both clay and concrete tiles are very porous meaning water causes eventual wear and tear on them resulting in costly repairs. After rain, heat and throw in freezing, the tile roofing eventually cracks under the pressure. Water traps in the pores of the tiles and then when exposed to the heat of the sun bearing down on them, they dry out only to be followed up with repeated abuse of re-absorption of water through further rainfalls and cold and warm conditions. The repeated expanding and reduction effect due to environmental factors cause clay and cement tiles to crack and break. Broken tiles on a roof leave the rest of the home exposed to serious water damage. 


Tiles admittedly give a home a quaint look, but their efficiency is less then desirable for any wise homeowner. Metal roofing offers a lot more in durability as well as being aesthetically pleasing to the eye. In looking at the environmental factor alone, metal-roofing pays for itself ten fold over in what it saves the consumer in repairs alone.


Metal roofing can last the lifetime of a home. Repairs are minimal and are generally due to homeowner inflicted damage such as when attaching solar panels or other hardware on the rooftop. A metal roof is so durable it can withstand winds up to 190 kms per hour with no lift up. Even severe hailstorms cannot phase metal roofing, unlike the severe damage a hail or windstorm can do to tile roofing. Christchurch homeowners can even benefit from having a metal roof over a tile roof through insurance deductions, yet another cost effective reason to have metal roofing.


With metal roofing, you never have to worry about chipping, rusting, fading or chalking. The colors do not fade no matter how hard the sun beats down on the roof. The heat reflective facet of metal roofing saves the Brisbane homeowner money through its energy saving factor. Not only does a metal roof save a homeowner a ton of money they also come in a wide variety of colors and styles to meet any homeowners taste setting the home apart from the rest of the block. 


After a tile roof has been laid and finished it can still move as the house settles, this in 
Turn makes the tile crack or the bedding two crack or even look not straight to the eye.
When you screw down a new metal roof you will find un like the tile roof the new 
Metal roof will not move and this in turn gives your home better structural integrity.

What To Look For In A Roofer?

We’re not talking about a beard, work boots, or stubbies here. Avoid getting a dodgy job done by sussing out your potential contractor first to ensure that you’re hiring a quality roofing professional. That’s right, don’t be nervous about asking to see their certificates and check up on their references.  Find out how many years they’ve been in business and whether they're a member of the Roofing Association of New Zealand or RANZ.  Remember to ask about warranties on work (which can range from 1 or 2 years up to 10 years, depending on the job) and make sure they’re up to date with their insurance for liability as well as worker’s comp.

An honest roofer will know exactly what you need and won’t beat around the bush. When the tradesperson comes out to inspect your roof they’ll be able to give you a rough estimate of the time and cost involved. Don’t be afraid to say no, or ask for a better price. This quote should always be free. If it’s a new roof, or a large job, they might require you check with the Council for Building Consent. Estimates for jobs can range from $90 for a small tile patch up job, up to $30,000 for a new 200m² slate roof.
