Metal Roofing

Q: Do I need strapping for a metal roof?

Depending on the style of roof, strapping may or may not be required. If the option is available strapping is advisable, as it helps reduce condensation buildup and extends the lifespan of your roof. Double strapping provides better insulation, in addition to smoothing out any dips or bumps.

Q: How far should a metal roof overhang?

In Australia, a metal roof should have about 5 cm of overhang. As little as 2.5 cm should still work for most situations. You should never overhang a roof further than 10 cm without support structures. With the appropriate support structures, it can overhang as far as required.

Types of metal roofing

Corrugated metal roofing

Corrugated roofing combines the fireproof and watertight benefits of sheet metal with the affordability of asphalt. It is thinner and more prone to rust than other forms of metal roofing sheets.

Standing seam metal roofing

A standing seam system is made of vertical panels with interlocking joins. This makes it easy to install and provides a high degree of strength and weatherproofing.

Metal shingles

Metal shingles are made of overlapping plates and can be visually stunning, especially copper roofing. Costs in Australia depend on the material and size of the individual shingles used.

The advantages of high quality metal roofing

High quality metal roofing systems can last from 30-80 years in Australia, much longer than other roofing materials. Quality metal roofs also save you power in summer by reflecting sunlight, keeping the house cool. Houses with these roofs installed tend to resell significantly above those with asphalt shingles. This all means that it is stronger, more durable, and more cost effective than other roofing materials.

Can metal roofing be installed directly over plywood?

No, it should not be applied directly over plywood. To prevent damage and leaking, a felt sheet and slip sheet should be placed between the plywood and the metal. Ideally, at least one layer of strapping should be placed between the plywood and the roofing to allow for proper ventilation.
