We Transformed This Roof In Kangaroo Ground with A Metal Roof Replacement!

A recent job completed, a 300m² metal to metal re-roof. 50mm blanket backed foil is used under the roof sheets to provide thermal resistance and nose reduction, making your home more comfortable and energy efficient. Here’s how we replaced this roof in Kangaroo Ground with new Colorbond roofing!


Here is a roof replacement in Kangaroo Ground that we completed. We removed and replaced the existing corrugated iron. There was an old flat roof section that had a box gutter with a side chute. We re-designed this box gutter to have a drop into a sump to comply with regulations. After we had replaced the roof the home owners were happy with our service and asked us back for the guttering to be replaced.

The Process

Initial Contact – When can I get a free quote?

We were contacted by the home owners and a request for a quote was established. The same day we were called we made a site visit and measured up the roof. We were able to have a speedy turn around and send off a quote within just a few hours off initial site visit.

Quote - Will our quote include everything?

Once the measurements were gathered, we could price up the job. Our prices can be worked out in several different ways and always result in being within the range off our competitors quotes. Our quotes will include all products and services required from us from start to finish and includes all our rubbish removed and all required safety equipment.

Schedule – When can you start the job?

Most of the time it takes about 4-8 weeks to schedule the job in. Multiple factors play a part in this. This is usually a perfect time to wait anyway so we van work out any kinks and finalize colors and products.

We usually ask for a deposit to secure your position in the upcoming weeks.

Delivery - When will the materials arrive?

Materials will be delivered on the day we begin or in some cases the day prior. Sometimes if the job is starting on Monday, we will coordinate the delivery to be the Friday prior to starting. This means that we can start straight away.

This isn’t always the case, maybe there is not enough storage space on the property and we have to store the materials in certain areas. We will be in communication with you along the way and let you know when you can expect us. Most properties in Kangaroo Ground will have ample space to manage materials and deliveries with ease.

Site Safety - Is the job completed safely?

Where we can fall 2m or more; safety rails or another means of fall protection is required. For this one in Kangaroo Ground we had the safety rails set up on the Friday before starting on Monday so we had all our safety requirements checked off before starting.

Coordinating this close to the start date also means that the equipment isn’t left hanging around for days/weeks before and after the job.

Sheet Metal Removal - How are the roof sheets removed?

We strip the metal from the existing roof and organize a pickup from a local collector, they will take to a scrap metal recycling yard. This ensures the scrap metal is recycled appropriately.

We remove parts of the roof in sections that we will be able to cover that day so we will rarely require the use of tarps.

Job Start

To start this on we check and make sure that the weather is suitable to remove the roof in. If it is forecast for rain we will have to reschedule and push the job back a day or two until the weather is suitable. Once we are green lit, we begin striping the roof sheets. When removing corrugated iron and replacing like for like it goes fairly quickly.

On a hip and valley type roof we will do one hip at a time. We will strip that section, install the new battens, lay the new blanket and then the sheets.

On a metal roof we will inspect the frame on initial site visit if possible, to asses battens. Some situations may prevent us from doing so. In the event that we cannot determine if the battens need replacing, we may agree on replacing only if required.

For this one in Kangaroo Ground, the roof was in pristine condition so we did not need to replace the battens.

We then lay down our 60mm Anticon roof blanket. This is great for sound absorbance and thermal resistance. The Anticon is short for anti-condensation. The roof blanket stops condensation from formation the underside of the sheet and dripping into the ceiling space so this is a highly recommended product for metal roof.

After the blanket is down, we start laying the sheets. The sheets will be cut up the hips and each offcut sheets will be spun around and positioned into another location- much like a jigsaw puzzle.

Each set of sheets cut will have an opposite set on the adjacent side of the roof. These cuts on the angle are what we call a ‘rake’. The rake cuts are done on site by hand with tin snips or battery powered shears.

It’s important the we lay the sheets straight so after each sheet laid, we will check and make tiny movements either stretching out the sheet or shrinking the sheet back in. After all sheets are laid, we will install the rolltop ridging. The ridging can be an artform of itself. Where the ridge meets at three or more places, we will cut the joins in neatly and will make watertight.

For this roof we are replacing the skylight flashings only.

Some existing acrylic skylights can be in okay condition. In this situation we will completely reflash the top unit to match the new roof colour. Depending on roof pitch and we will either back tray or soaker the skylight flashing. For this roof in Kangaroo Ground we performed a soaker flashing. This uses less material and kind of blends into the roof a lot neater. If the roof were to be flat, we would go with a back-tray flashing. That means that the flashing will slide up under the ridge. You can see so here on another of our jobs.

There was a flat roof section that had potential to be upgraded. The existing box gutter was quite shallow and only discharge through a 100mm side chute with no overflow. This could have been an issue in the event of a large downpour.

We upgraded a box gutter to have a sump a rain head. This will increase the capacity the gutter can handle and will comply with current regulations.We were also able to raise the flat roof up giving the box gutter more depth. This meant that the gutter from the main roof was no longer required and we could install a transition flashing.

We changed over the guttering to slotted quad gutter. The slots make sure that any water cannot overflow into the house.

Once we had completed the roof the handrail was off hired and removed from site. All the bins were taken away and all rubbish removed.

Job Completion

On completion we go through any problems and issues that we may have come across. We email out the compliance certificate along with any other information requested.

Some roof replacements may take us 2-3 days, while others may take 6-7 days.

Our philosophy is to not rush anything and value overall quality over speed. We only remove sections of the roof that we can cover in that day, so we rarely require the use of tarps, but if required we have access to hire easily!

This roof replacement in Kangaroo Ground was completed over 7 days which included the site clean-up.
