Roofing Shoes for Metal Roofs


Created by roofers for roofers

Magnetic Roofing Shoes

After five years of design, development and testing, the specialised Magnetic Roofer® is vastly superior to any roofing footwear you have worn in the past.

These roofing shoes come with a patented magnetic sole that's designed to offer extra grip, better traction keeping you safe when you need it most.

Created by roofers for roofers

This shoe is safer, provides much better traction and has a 100% rubber sole with a comfortable and durable, industrial grade micro fibre upper.

These Roofing Shoes are magnetic

The magnetic sole of the shoe keeps you safe on the roof with minimal lateral sliding whilst the upper contours the foot assuring a comfortable fit.

Magnetic Roofing Shoe features:

  • Upper made from industrial grade Micro Fibre
  • 100% flexible rubber sole maximising grip and comfort
  • Industrial grade stitching
  • Low cut design for comfort
  • Upper made with breathable mesh panels to help with airflow
  • Available in sizes from Size 8 - Size 13 
  • There will be 1 magnetic cleaning tool supplied with every pair of new shoes.

Roofing Shoes

Non magnetic roofing shoe

A non-magnetised alternative, the Roofer® is a flexible design with excellent grip and comfort.

With a 100% rubber sole and an industrial grade upper that is built to last, this shoe gives you good traction.

It allows you to contour your foot to the roof profile and maintain firm contact with the surface.

Roofing Shoe features:

  • Upper made from industrial grade Micro Fibre
  • 100% flexible rubber sole maximising grip and comfort
  • Industrial grade stitching
  • Low cut design for comfort
  • Upper made with breathable mesh panels to help with airflow 
  • Available in sizes from Size 8 - Size 13 


So How Does The Magnetic Sole Work?

With the soles of the shoes being magnetic they offer you extra grip on flat metal surfaces.

The strong magnets in the sole magnetizes your foot to metal surfaces assisting in sliding on steep metal gradients but will allow you to freely lift your foot to walk.

A concept a bit like a fridge magnetic, you cannot slide the magnet down your fringe but you can easily pull the magnet off the metal surface.

So How Long Do The Magnetic Soles Work?

There will be no loss in magnetized force from within the sole of the shoe however the soles of the shoes will wear out with use affecting the use of the shoes.

Once the wear reaches a certain point the shoe will need replacement.

So What's The Difference Between the Magnetic & Non-Magnetic Shoes?

The roofing shoes are NOT magnetic, they are a standard type of roofing shoe.

The roofing shoes have been designed with 100% rubber soles maximizing flexibility and comfort on your working profile.

Breathable and soft they will warm as you work assisting in grip to help with stability.

Replace Tile Roof With Colorbond, Which Is Better?

 Replacing your concrete tiled roof with a Colorbond Metal Roof

Looking To Replace Your Tile Roof With Colorbond, Which Is Better?

Roofing is a very important part of your home and represents a substantial financial investment so when it comes to replacing your old tile roof you need to get some solid advice.

Concrete tiles have been used on Australian homes for some 70 years but Colorbond metal roofing has also built a solid reputation for durability and dependability.

There is one question you need to ask yourself...

... is it better to replace your old tile roof with tiles or covert your tile roof to Colorbond steel?

Whether you are replacing your tile roof or putting a roof on a new build getting the right information about the following aspects will help you answer that important question: 

  • Benefits or pros and cons of tile versus Colorbond
  • Costs - price difference between Colorbond and tile roof?
  • Risks - do tile roofs require more or less maintenance than Colorbond?
  • Installation difficulties - which is easier to install?
  • Resale / property value - will a new Colorbond roof increase the value of my property more than a tile roof?
  • Choosing the right type of Colorbond product - what else do I need to know about Colorbond versus tile roofing?
  • Getting qualified / experienced trades people - who can I trust to install my Colorbond roof correctly?

No.1 Roofing and Building Supplies is one of the largest suppliers of Colorbond roofing materials and accessories in the Sydney area and our outstanding expert advice and access to premimum installers is second to none.

What are the benefits of colorbond vs tile?

What Are The Benefits of Colorbond vs Tile Roofing?

Both Colorbond and tile roofs have their advantages and sometimes the design of your roof will actually dictate one or the other.

Concrete or terracotta tiles have been used for roofing in Australia for more than 70 years and offer a very traditional look.

The first Colorbond products were developed some 50 years ago and the hi-tech manufacturing processes and considerable product development since then have resulted in an outstanding product.

Plus, Colorbond is backed up by a solid warranty.

  1. Weight - Colorbond is much lighter than tile roofing, as much as 90% lighter. Not only does this mean that handling and installation is easier and faster but the roofing subframe is not subject to heavy loading and you can even use lighter battens and space rafters further apart for another cost saving.
  2. Lifespan - Colorbond roofs can have a life expectancy of up to 70 years whereas tile roofs are easily damaged and prone to cracking under typical Australian weather extremes. Problem leaks also frequently occur round the ridge capping areas on tile roofs. Colorbond ridge flashings are much simpler to install and more reliable.
  3. Water collection - older tile roofs absorb a certain amount of water, which not only adds to the weight of the roof but reduces the amount of water you can collect. This may prove critical in times of severe drought. Tiles tend to crack and the resulting dirt build-up encourages the growth of moss and mould that can contaminate your drinking water. With a Colorbond roof all the rain is collected as clean water fit for household use.
  4. Maintenance - Colorbond roofs offer a low maintenance roofing solution with a stable surface. Even when maintenance work is needed such as cleaning or repainting there is little chance of damage to the metal roofing panels. On the other hand, tile roofs frequently crack exposing the sub roofing to water damage and allowing a build up of dirt. Simply walking on a tile roof may be enough to dislodge or crack tiles. Heavy tile roofs may even require periodic strengthening or replacement of roofing support structures.
  5. Insulation - as a minimum Colorbond Roofs should be installed with a 55 mm thick foil adhered insulation blankets under them. This blanket provides thermal, acoustic and condensation protection. This isn’t the case with tile roofs which are commonly installed with just plain foil or sometimes without even that under them.
  6. Design flexibility - Colorbond roofing is much more flexible for designers than tile roofing. That’s why we’ve seen a swing of architecturally designed buildings being specified in metal roofing rather then tiles in recent years. With many colour choices and design options Colorbond roofing is a creative designers dream product.

One of the other big advantages of Colorbond steel roofing over tile roofing is that you can install Colorbond on very low pitch or even flat roofs.

Tile roofs require an adequately pitched roof angle to avoid leaks.

This can be a major consideration when you have height restrictions to work to but need to maximise your building space.

What Does it cost, concrete tile vs Colorbond

What Does It Cost To Replace A Tile Roof With Colorbond?

There are many variables when it comes to costing any roof. The only way to be sure is to seek firm quotes from qualified installers.

On average standard Colorbond corrugated roofs will be roughly the same price as standard concrete tiles roofs.

The big savings come in over time.

Lower maintenance, better insulation, better storm damage resistance and even the potential for lower premiums on your home insurance are what makes Colorbond Roofing the big winner when you put it head to head with tiles.

Is Colorbond Roofing More Difficult To Install Than Tiles?

Colorbond steel is a breeze to install for experienced trades people.

As with any roofing material it’s critical to install the roof in accordance with the building code and manufacturer’s instructions but metal roofs are remarkably resistant to damage from trades people walking on the panels or other damage.

The lightweight and cut to length properties of Colorbond Roofing mean that large areas can be rapidly installed by fewer people so you minimise the exposure of your property to multiple people – which in turn reduces the risk of damage.

Tiles are heavy and this can create real problems and extra costs in transportation and installation. Due to the labour intensive nature of installing tiles

– tile roofing teams tend to be larger then metal roofing teams – which increase the risk of damage to your property during installation.

Tile roofs can be more fragile and can be easily damaged by trades people walking on the roof

– which means that they can be easily damaged by follow on trades like antenna installers.

Tile pointing and roof capping can also be challenging areas when installing tile roofs and require very careful attention.

Does metal roofing help to increase my property value?

Will Colorbond Roofing Increase My Property Value More Than Tiles?

Colorbond is arguably the most popular and brand aware roofing material in Australia today...

... and Colorbond roofs are seen as increasingly desirable by potential property buyers.

Personal preference will always play a part in determining property values and terracotta tiles can look really smart on particular styles of houses but Colorbond roofing is becoming the roof of the future.

So, in short, replacing tired old roofing tiles with Colorbond is going to add a real boost to your property’s value.

How Do I Choose The Right Colorbond Product?

Colorbond steel has been tested and designed for Australian conditions and it’s made right here in Australia.

A variety of Colorbond steel roofing products are available to suit a range of conditions including:

  • Coastal and other high corrosion environments—choose the Colorbond Ultra steel or Colorbond stainless steel range 
  • Normal Australian condition and locations—choose from the standard Colorbond steel range

Once you’ve decided on the appropriate Colorbond steel for your location your toughest decision will be to choose from the amazing Colorbond colour range.

BAL FZ – What Is It & What You Need To Do About It?

BAL FZ - What It Is & What You Need To Do About It?

BAL Flame Zone & Building Code Requirements

Bush fire—two simple words that are guaranteed to raise your stress levels and your insurance premiums.

Although Australians have never taken bushfires lightly the forecast is that bushfire intensity and frequency are only going to get worse.

The Australian Building Code has always acknowledged the serious financial and social cost of extreme bushfire events and it attempts to reduce their impact through legislation governing building design and materials.

The new BAL FZ (Bushfire Attack Level Flame Zone) is the most extreme rating that can be applied to building design and construction.

BAL FZ is now applicable to wide swathes of NSW including a large number of North Shore and Northern Beaches suburbs.


Why Is BAL FZ Needed?

The devastating 2009 bushfires in Victoria led to a complete re-think of the old bushfire standards.

The new BAL FZ is the most extreme level in the revised bushfire attack standards and represents how successfully particular building materials will withstand bushfires in regards to ember attack, radiant heat, and direct flame ignition resistance.

The sad reality is bushfire incidents are increasing in intensity and the social and financial costs are spiralling out of control.

A 2016 Climate Council report stated that bushfires currently cost the NSW region around $100 million dollars each year and this is forecast to rise to $800 million by 2050.

The social cost comes through loss of life and injuries, and the upheaval and dislocation that are a natural result of severe bushfire events.

For most homeowners the increased building and insurance costs associated with meeting code compliant new builds and DIY projects or renovations means that you need to do your homework before you start any building project.

Bush Fire Danger Ratings

What Does BAL FZ Mean For Me?

If you are building in a bushfire zone that requires BAL FZ compliance you need to use BAL FZ compliant materials.

This requirement also has implications for your insurance cover, as insurance companies will take a dim view of claims for fire damaged new builds that do not comply.

Although the updated requirements are more stringent the code does provide for choice. The BAL FZ essentials for windows and external doors including sliding, French and bi-fold doors are either:

1. All open able portions need to be internally or externally screened with metal (steel or bronze) screens with a maximum aperture of 2mm


2. The window or door system must comply with AS1520.8.2 when tested from the outside and have an FRL of at least -/30/-. FRL (Fire Resistance Level) -/30/- indicates that the integrity of the window will remain intact for 30 minutes of exposure to fire.

BAL FZ requirements for more substantial parts of a building including walls, decking, roofing, and exposed floors mean that combustible materials are not permitted in these areas.

This does mean that your building costs may be significantly higher but you don’t have to build an ugly Fort Knox to comply with the code.

Many traditional non-combustible building materials such as stone, brick and mud brick still comply with the BAL FZ code. Essentially, if you can’t burn it it’s probably going to be alright.

Roofing for BAL FZ - What Are Some Good BAL FZ Rated Roofing Materials?

Roofs and roof insulation need to meet or exceed an FRL of 30/30/30 for BAL FZ compliance.

Colorbond or Zincalume steel roofing panels remain an excellent choice for your BAL FZ compliant roof. Bradford’s Anticon is a high-performance foil-faced insulation blanket that will reduce heat transfer significantly and is rated as compliant with BAL FZ requirements.

The eaves are a potential danger zone especially where fire has taken hold of vegetation close to the house.

For this reason a fireproof insulation material such as Anticon 80 compressed to 40mm should be used in the eaves. The underside of the eaves should be further protected by a fireproof material such as HardieFlex.

Bradford Fireseal FZ is a rock wool fire resistant roof insulation that will help prevent embers or flames taking hold in the roof space and these are appropriate for metal or tile roofs in BAL FZ zones.

For tile roofs you will need Bradford’s Thermoseal Roof Tile sarking, Flexitel blanket, and Fireseal FZ tile roof batts.

And you cannot install roof-mounted evaporator cooling units in BAL FZ zone unless they have been tested and meet the requirements of AS1530.8.1.

Non-compliant units must be fitted with an approved ember protection screen or in the case of a flammable cooler unit, completely covered with a non-combustible cover.

Cladding for BAL FZ - What Are Some Good BAL FZ Rated Cladding Materials?

James Hardie offers a number of cladding options that will satisfy the BAL FZ requirements and provide an attractive appearance including: 

  • HardiePlank and Primeline for a traditional weather board look 
  • Scyon range of advanced fibre cement composite cladding panels 
  • Panel Clad pre-textured sheets for a Mediterranean stucco finish or a rough hewn timber look 
  • HardieTex—the original fibre cement cladding for a smart modern look 
  • HardieFlex—perfect for lining the eaves

HardieFire mineral wool insulation is a great choice for insulating walls but as with any product it must be installed to correctly to meet the code’s requirements.

HardieFire insulation must be cut to at least 5mm wider and longer than the space between each frame cavity. This ensures there are no spaces where oxygen can feed any potential fire.

FireCrunch fireproof board is a highly cost-effective exterior wall cladding with FRL levels of 90/90/90 on a steel frame and 60/60/60 on timber; these ratings greatly exceed the minimum BAL FZ requirements.

It is ten times stronger than ordinary plasterboard and won’t degrade in water. FireCrunch is also termite proof and it can be painted, rendered or tiled.

FireCrunch is made from magnesium oxide recycled from the steel industry so it’s good for the environment too.

Decking & Flooring for BAL FZ - What Do I Need?

To meet the BAL FZ requirements decking must be made of non-combustible material and have no gaps. This also means that the decking/flooring supports must either be non-combustible (steel or concrete) having an FRL of at least 30/30/30 or be fully enclosed.

Many of the fibre cement type panels are ideal for decking and floors too.

FireCrunch doesn’t just look great on your walls but with 16mm and 21 mm thicknesses it’s also perfect for flooring and decking in BAL FZ zones.

It can also serve as a substrate for other decking treatments such as tiles. Plus, you know these products are a tick for good environmental practices.

The Hardie fibre cement range such as the Scyon Secura exterior panels offer great options for any deck.

Not only are they inflammable but they have remarkable weight bearing strength characteristics as well. Scyon Secura functions as a great substrate for tiles or other flooring finishes.

Can I Still Use Timber Products?

Yes, in accordance with BAL FZ requirements you can still use timber products but only specific types of timber and only in particular situations.

External window framing is considered inconsequential and timber may be used where the timber density is higher than 650 kg/m and with a moisture content of less than 12%.

This includes but is not limited to hardwood species such as: 

  • White Cyprus
  • Ash (Alpine, Mountain, Silvertop)
  • Beech Myrtle
  • Gum (Southern Blue, Mountain, Sugar)
  • Jarrah
  • Ironbark (grey, red)
  • Mahogany
  • Celery top pine

Wood may be used in other features of your house such as fascia boards.

Don’t forget, you do need to have ember proof metal shutters that completely cover all externally opening non-compliant wooden windows or doors.

Are Sealants Covered By The BAL FZ Code?

Yes, because many sealants and adhesives contain potentially flammable compounds.

Compliance also requires the use of fire rated sealants because embers and super heated air can bypass fire rated barriers through poorly designed or constructed wall penetrations and trigger fires inside roof or wall cavities.

We stock a wide range of fire rated sealants and adhesives including: 

  • Bostik Fireban One sealant 
  • Selleys Fireblock 
  • Sika Fire rate PU—an external, fire-rated sealant that retains its flexibility and watertightness in all weathers

The products mentioned in this guide are just some examples to get your creative juices flowing. We can supply an enormous range of products appropriate for your needs so come and talk to the friendly experts at No1. Roofing and Building Supplies and let us help you realise your vision.

Please be aware that this is a guide only and you need to seek professional advice and check your intended design complies with Council and code requirements before you go ahead with any building project.

Rapid Ridge – An Australian First for Roofing

Rapid Ridge - An Australian First for Roofing

Rapid Ridge - How it Works

Rapid Ridge heralds a new dawn in roofing in Australia, a Ventilated Dry Ridge System.

The Rapid Ridge system facilitates an open ridge that allows the roof to breathe with the use of an advanced double labyrinth ventilated fleece.

This fleece has been tested to provide both ventilation and protection from driving rain.

This allows a mechanically fixed fully passive and ventilated dry ridge that will be effective on any home – tile or metal.

This solves a number of problems but in particular in Australian warmer climates where radiating heat and trapped heat means higher air conditioning bills to dissipate this heat and achieve suitable comfort level.

Whirly birds and other such methods will ventilate a small part of the roof, require maintenance, they look unpleasant on the roof and in reality are very ineffective.

Rapid Ridge - How it Looks On Your Roof

Passive Ventilation - No Moving Parts

Rapid Ridge allows the whole roof to be ventilated passively with no moving parts.

Significantly less heat gets into the attic space and tests have shown that home owners can save up to 43% on cooling energy costs by installing this system.

For the roofer or builder the appeal comes in the installation as it can be done in less than half the time to the traditional method.

Advantages are lightweight materials, unlike buckets of mortar being carried up ladders to bed the ridge and time saving in not having to call back on the 2nd day to finish off the pointing and hoping that it does not rain!

The Rapid ridge can be installed in one visit by using the unique components together to build a compliant and healthier house in less than half the time.

Rapid Ridge Ventilated Dry Ridge System

Why Make the Switch?

The Home Owner benefits with a cooler & healthier home. 

  • Achieve all the benefits of roof ventilation with a no maintenance complete passive system
  • Save up to 43% on cooling energy costs during the year
  • Incorporate world best roof building practice into your home for long lasting roof functionality

The Builder/Roofer benefits with lower cost to install. 

  • Install a dry ridge system in less than half the time compared to mortar and pointing
  • Use a tried and tested complete system that is in use throughout Europe
  • Use one product that is dry and clean for universal application on ridge and hip (in most weather conditions)

The Architect benefits with a better looking and functioning roof. 

  • Promote best practice that is better for the environment and better for the home owner into your designs
  • Be first to market and educate your clients on an Australian first that is widely used in Europe
  • Achieve improved aesthetics on the roof with better ventilation (i.e. no whirly birds!)

Rapid Ridge - How it Installs

It's Been Tested by the CSIRO

Rapid Ridge is a mechanically fixed, dry ridge maintenance free fully passive and ventilated system.

Tested by CSIRO for weather proofing and ready for installation on new homes that incorporates best roof building practice into the modern home.

Roof Ridge Capping – A Critical Aspect of Any Well-Sealed Roof

Ridge Capping, Colorbond, Zincalume, Galvanised and Polycarbonate

Ridge capping is a critical aspect of any well-sealed roof.

It’s usually the last feature to be added to your roof but it is vitally important that it’s done correctly, as ridge capping prevents water and wind from getting underneath your roofing tiles or sheets through the highly exposed and vulnerable ridge seam.

Ridge capping also adds an attractive finish to the roof line.

Ridge capping comes in many different types and materials and No1 Roofing supplies a wide range of capping products and accessories to cater for all roof types including polycarbonate translucent plastic panels.

How Does Ridge Capping Work?

Ridge capping both looks and functions like a kind of V-shaped or rounded flashing. Roof ridge caps are fixed to the ridge lines with sufficient overlap across the sheets underneath and also feature a downwards folding lip to prevent wind or capillary action driving moisture into the roof cavity.

Ridge caps are an essential part of your roof’s drainage system. As with any roofing product it is critical that you choose the appropriate product for your requirements.

Things to consider include: 

  • Using appropriate roof materials for your area— corrosion zones, council requirements etc.
  • Checking that roofing materials are compatible with each other
  • The angle of your ridge capping will be affected by your roof pitch
  • Matching roof aesthetics

Correct installation and the use of appropriate fasteners is also pivotal to the long-term life and function of your new roof. Doing it on the cheap never pays so talk to the helpful No1 Roofing experts and avoid those costly mistakes.

Installing Ridge Capping

Installation is critical to the long term health and function of ridge capping. You need to think carefully about:

  • Material compatibility—this includes the type of timber sub-frame and the fasteners used as well as other roofing materials that may impact on the ridge capping. Be mindful also of water runoff from other roofing materials that might be incompatible 
  • Recommended fastener spacing 
  • Correct tightening of fasteners—too tight and washers may be damaged or the sheets deformed leading to moisture entry around the screw head 
  • Checking if you need a particular scribing break to fit your roof profile 
  • Using the correct scribing or notching tools for fitting the ridge cap lip snugly around the ridges on ribbed or corrugated profile sheets

Choose an appropriate silicone sealant to seal overlapping joins.
