6 Common Mistakes Property Owners Make When Deciding On A New Roof


According to statistics, roofing is one of the most dangerous jobs in the world. There are plenty of do-it-yourself maintenance jobs that property owners can perform, but roofing is not one of them.

Roofing materials are readily available to purchase through hardware stores and through the manufacturers themselves, but that doesn’t mean you can replace or repair that roof yourself. Manufacturers will only offer a warranty for materials installed by a licensed contractor.

Furthermore, there are important decisions to make when purchasing and installing a new roof system. There are structural, ventilation and installation requirements and standards that need to be met, not to mention safety issues.

It is for this reason, that roof repairs or replacements should only be carried out by qualified, licensed and insured professionals, like those at Hindmarsh Roofing.


We are sure you have heard the expression, ‘you get what you pay for’ and the same applies for roofing estimates. If you have obtained several roofing quotations and one is well below the price of the other quotations, analyse the items listed and ensure that it is comparable. Confirm that the quotation includes the same scope of works, materials, accessories and warranties offered. Often a significantly lower price than the others may indicate that the subcontractor will be cutting corners or using substandard materials.

Also if a contractor claims to be the cheapest without even getting an estimate or will beat any quote, you do not want them working on your premises. They have to make a living like anybody else and the cheapest price generally doesn’t get you a quality job. You may initially pay less to go with the cheapest contractor but it might cost you more in the long run.


The deals that sound too good to be true, usually are…We have all been confronted with them – the high pressure salesperson who offers you that ‘special deal’ only if you sign on the spot today or you will lose that ‘special deal’. Generally, the only individual who benefits from this is the salesperson because he gets a bigger commission for getting the contract signed quickly.

A reputable roofing company won’t require you to sign on the spot by offering you discounts, a free barbecue or ‘I’ll call the manager’ deals. In addition, if a company provides you with a roofing quotation and then discounts the quotation by more than 10%, you may want to rethink and question their price margins and how overpriced their roofing services may be in comparison to other roofing companies.

All quotations will have an expiry date, but they should be valid for a period long enough to source other quotations, discuss your options and make a sound decision.

Hindmarsh Roofing does not employ salespeople or commission based staff. The individual who comes to assess your roof is employed by Hindmarsh Roofing because of their knowledge and experience in the roofing industry.


It may be possible for a roofing company to commence work on your premises immediately if they have had a cancellation or if it’s not peak season. However you should always do a little more investigating.

These days it is difficult to differentiate between a reputable and established roofing company and individuals who have  recently started their business. With today’s technology, everyone can have a website, claim to be experienced and show you examples of their work by purchasing stock images.

Ensure you place your premises in reputable and experienced hands and find out how long the roofing company has been in business. Do they have all the necessary licenses, insurances, offer warranties and are they certified by the manufacturers whose products they are proposing to install.

With all the details involved in purchasing a new roof, many property owners forget to ask about warranties and what happens if something goes wrong with the roof after installation. Your contractor should be offering you both material and workmanship guarantees in writing.

The workmanship warranty on offer demonstrates a roofing contractor’s confidence in their work and customer service. This reinforces the point that it is important to confirm how long the company has been in business and whether they have the ability to honour the warranty in the future.

A reputable roofing company should be a certified or approved contractor for the products they are installing. Leading manufacturers will only provide a product warranty on new materials if they are installed by a licensed roofing contractor.

It is imperative to deal with an established company with a proven reputation. At Hindmarsh Roofing, we offer our clients a 10 year workmanship warranty. We are fully licensed, insured and only use and recommend genuine Australian made steel products and materials.


Whilst recommendations from family and friends are helpful, using the services of a handyman that is not qualified, licensed or insured is leaving property owners in an extremely vulnerable position.

Over the years we have seen work carried out by handymen that have resulted in poor workmanship and as a result homeowners have been left high and dry with unfinished roofs and water damaged homes.

What may have initially sounded like a wise investment has ended up costing the property owner twice to rectify problems that should have been done correctly the first time.


Your property is more than just a roof over your head, it is probably the single biggest investment you will make in your life time and your roof is undoubtedly the most important part of your premises. It protects your whole property against every weather condition, rain, hail or shine. So it is essential you look after your roof to protect your family and your investments and it’s even more essential that you use a reliable and professional roofing contractor to carry out any roofing repairs or replacements.

Don’t let your roof become your biggest regret, get quality roofing advice and service from professionals. Call Hindmarsh Roofing in Adelaide today on 08 8268 1600 or fill out our online contact form for a free quotation and friendly, professional advice.

Why Metal Roofs Are Popular In Adelaide & South Australia

COLORBOND® and ZINCALUME® are both iconic brands that have become household names in Australia. Whilst there are many different kinds of metal roofing options, COLORBOND® Steel and ZINCALUME® Steel are the most commonly used in Australia.

For over 45 years COLORBOND® Steel has evolved into one of the worlds most advanced building materials.

Today, according to research carried out by BlueScope Steel, nearly half of all new homes in Australia have roofs made from COLORBOND® Steel, 9 out of 10 new homes built in Australia feature products made from COLORBOND® Steel and over 80 per cent of all Australian gutters and fascia’s are made from COLORBOND® Steel.

COLORBOND® Steel has become Australia’s single most popular roofing brand.


ENERGY EFFICIENCY – Using thermally efficient roofing materials like COLORBOND® Steel can help reduce your cooling costs by up to 20 per cent. Combining COLORBOND® Steel with Thermatech® technology and insulation will help your building remain comfortable all year round. In summer, air-conditioners have an easier job keeping your building cool, thereby saving money on energy costs as well as reducing emissions from electricity generation. In winter, the same metal roof, properly insulated will help keep the heat inside. The choice of colour can also influence thermal performance. Lighter colours, in particular, radiate less heat during summer.

ECO–FRIENDLY – Metal roofing is considered a green material because it is recyclable, reusable, sustainable and practically maintenance free. Steel is 100% recyclable and is one of the world’s most reused materials. It is durable and lightweight making it more efficient and cost effective to transport. Sheets are pre-cut to required lengths so there is less wastage, thereby reducing the impact on the job site and its surroundings.

LONGEVITY – Iron roofing is made to withstand harsh conditions of a dry sunburnt state like South Australia. 45 years of research and development in Australia alone, under some of the toughest conditions our country has to offer, has proven for many years just how durable metal roofing can be. COLORBOND® and ZINCALUME® regularly outlast the range of BlueScope Steel manufacturer’s warranties (up to 30 years) that are offered for a variety of applications.

VERSATILITY – Metal roofs come in a wide variety of colours, profiles, textures, finishes and styles. From basic to intricate, metal roofing can be shaped to your needs. It suits both heritage and modern style homes and is the only option available for flat or low pitch roofs. There is also the appeal of being able to co-ordinate your home, the COLORBOND® range is available for wall cladding, fencing, downpipes, fascia’s, garage doors and even cubby houses and dog kennels, providing an aesthetically pleasing environment around your residence.

SECURITY & PEACE OF MIND – Metal roofing is very secure, someone attempting to enter the home cannot just lift a sheet of iron like removing a tile, to break in through metal roofing is a noisy, time consuming process. Metal roofing is generally installed in continuous lengths, made to order sheets, removing many joins and possible entry points for water to leak into your home. As well as looking visually appealing metal roofing is extremely strong, resisting strong winds and hail and providing a barrier from falling branches and debris. In addition, metal roofing is non-combustible, termite resistant and low maintenance.

We all know that weather can be unpredictable and with the extreme Australian conditions like torrential rain, hail storms, gusty winds and bush fires affecting homes right across the country, more and more homeowners are seeking the protection of a metal roof.


COLORBOND® Steel and ZINCALUME® Steel are some of the toughest, most advanced building materials in the world. With its baked on finish, COLORBOND® has been tried and tested for over 45 years in some of the harshest climates across Australia, so you can rest assured that COLORBOND® Steel not only looks beautiful, it is durable and has outstanding thermal properties.

Offering some of the best warranties in today’s market, BlueScope Steel offers a warranty against corrosion to perforation by weathering in the natural elements for a period of up to 30 years for COLORBOND® Steel and ZINCALUME® Steel from the date of installation. BlueScope Steel also warrants that the paint system on COLORBOND® Steel will not flake or peel due to natural weathering for a period of up to 20 years from the date of installation.
