A verandah gives a Dandenong home a roofed outdoor space that stays useful through the whole year. Moorabbin Airport, the nearest long-record Bureau of Meteorology station, averages about 700 mm of rain over roughly 103 wet days a year, so a solid roof that sheds water cleanly matters as much here as summer shade. Peak Pergolas designs and builds flat, gable and curved verandahs across Dandenong, Noble Park, Springvale, Keysborough and the rest of Greater Dandenong. Each verandah is measured at the house, drawn to suit its roofline, set on footings sized to a soil test and lodged for a building permit through a private building surveyor.

Verandahs in Dandenong are built in three main roof shapes. The shape is the first decision, because it sets how the verandah looks against the house, how much headroom it gives and how quickly it sheds rain.
A flat verandah has a skillion roof with a gentle fall, usually fixed to the fascia or raised on brackets above the gutter. It is the most economical shape, suits single-storey homes with a low eave and covers long runs along the back of the house. The fall is set so water runs to a gutter on the low side rather than pooling on the sheet.
A gable verandah rises to a ridge in the middle. On a home with a pitched tiled roof it is drawn to the same pitch, so it looks part of the original house. The raised centre lifts the ceiling, lets warm air rise away from the table and sheds rain to both sides. The open triangle at the end can be left open, filled with a timber or battened screen, or finished to match the house.
A curved roof sweeps down from the wall in a gentle arc. The bullnose is the traditional form seen on older Victorian homes, and a wider curved roof suits the back of a house where a softer line is wanted. The sheet is rolled to the radius before it arrives, so the frame is set out to that exact curve. A curved roof sheds water quickly and softens the front of a brick home.


A verandah does a different job at the front of a house than at the back. The front verandah is about shelter at the door and how the house looks from the street; the back verandah is about a usable outdoor room.
Much of Dandenong, Noble Park and Springvale was built in the decades after the Second World War, and many of those homes have lost their original front porch or have one that has rotted, sagged or been patched. A new front verandah is drawn to suit the house: the roof shape, post spacing and colours are taken from the existing home so it looks planned rather than added later. On a brick home the posts and beams are usually steel in a colour that picks up the window frames, and the roof is fixed to the fascia or a wall plate; on a weatherboard home, timber posts and a timber beam with a painted finish sit naturally against the boards, and the ledger is flashed behind the cladding so water cannot get in. It gives a dry place to stand at the front door and shades front windows from the afternoon sun. A verandah that projects towards the street is checked against the setback rules during design.
At the back, a verandah turns a bare slab or paved area into an outdoor room for meals, gatherings and drying washing on wet days. On newer homes in Keysborough and Lyndhurst the back verandah usually covers the alfresco outside the family room; on older homes it often replaces a tired timber pergola. Where the space needs to stay cooler in summer, an insulated patio roof is the alternative, and where a flat roof is wanted over a large area, patios cover the same ground.
A verandah lasts when the frame, the roof, the footings and the connections are all chosen for the conditions it sits in. In Dandenong those conditions are frequent rain, low and sandy ground in parts of the area, and a strong summer afternoon breeze.
Most verandahs are framed in galvanised steel, which spans further with fewer posts and does not rot or attract termites. Timber suits older homes where the posts are meant to match timber details on the house; the posts stand on galvanised stirrups clear of the soil. Roofing is Colorbond steel, chosen from the range to suit the existing roof, gutters and window frames.
Moorabbin Airport records rain on about 103 days a year. Winter brings the most wet days, around 11 to 12 a month in July and August, and October has the highest rainfall total. A verandah roof therefore deals with frequent, steady rain rather than the odd storm. The roof is set with a steady fall, the gutter runs the full length of the low side and is sized for the roof area, and each downpipe is connected to the stormwater system rather than left to spill onto the paving.
Much of the south of Greater Dandenong sits on the sandy country of the Melbourne Sandbelt or on land drained from the old Carrum Carrum Swamp, while other streets sit on clay. A soil test sets the AS 2870 site class and the footings are sized to it, so posts are held by the right depth and diameter of concrete instead of a standard hole.
The mean 3pm wind speed at Moorabbin Airport is 21.4 km/h across the year and peaks at 23.3 km/h in January, when the sea breeze comes in off the bay. Posts are bolted to stirrups or base plates, beams are bracketed to the posts, and roof sheets are screwed at the spacing the engineering sets, so the roof stays down when the wind gets under it.


Every verandah is priced from a free measure and a written, itemised quote, because no two houses, blocks or rooflines are the same.
The size of the roof is the biggest single factor. A flat verandah is the most economical shape; a curved roof costs more because the sheets are rolled to a radius; a gable costs more again because it has a ridge, extra framing and the end infill to finish. Steel and timber frames sit at different points depending on the span and the number of posts.
Narrow side access, a sloping block or a front yard with a fence close to the house all add labour. Removing and disposing of an old verandah or pergola is priced as its own line, as are any extra footings needed on soft or filled ground.
Every verandah in Victoria needs a building permit, so the drawings, the engineering for footings, spans and wind, and the application through a private building surveyor are part of the quote rather than an extra discovered later. The total is known before work starts, and the build begins once the permit is issued. The pergola and verandah permit guide explains the rules in more detail.
Verandah, pergola and patio are often used to mean the same thing, but they are different structures, and the right one depends on what the space needs to do.
A verandah always has a solid roof, so it keeps rain off and gives shade all year. A pergola can be left open with rafters or battens, which lets winter sun through and can carry a vine or shade cloth, but it does not keep the rain out. A patio is a roofed outdoor area, usually over a slab at the back of the house, and in practice a back verandah and a patio are often the same structure. For an open design, see timber pergolas; for adjustable cover, see louvre roof pergolas.
Verandah kits are sold in standard sizes, which suit a simple flat roof on a level site. A site-built verandah is drawn to the actual house: the fascia height, the roof pitch, the window and door heads and the fall of the ground. The engineering and footings are matched to the site, the permit is lodged with the drawings, and the frame is cut to fit rather than packed out to suit a standard size.

Drawings and engineering are prepared for the site and the building permit is arranged wherever one is needed.

Footings, frame and roof are built and inspected at each stage, the site is cleaned up and the finished structure is handed over.
The cost depends on the floor area, the roof shape, the frame material and the site. A flat verandah is the most economical, a curved roof costs more, and a gable costs more again. Removing an old structure and extra footings on soft ground are priced as separate lines. A free measure gives a written, itemised quote.
Yes. In Victoria the construction of any verandah requires a building permit. A registered building surveyor is appointed to issue it, and a planning permit must be in place first if one is needed. The drawings, engineering and application are prepared as part of the job.
Most of the waiting happens before construction, while the drawings, engineering and building permit are prepared. Once the permit is issued, a typical verandah is built in a few days, depending on its size, the roof shape and the weather.
Most leaks come from the join between the verandah roof and the house, not from the sheets themselves. Too little fall, a gutter that is too small for the roof area or poor flashing at the wall lets water back in. Setting a steady fall and flashing the junction properly prevents it.
A flat roof suits single-storey homes with a low eave and long areas along the back of the house. A gable suits homes with a pitched tiled roof and gives more headroom. A curved or bullnose roof suits older brick homes and the front of the house.
The area is measured, along with the fascia height, the pitch of the house roof and the fall of the ground. Access, existing structures and drainage are checked, roof shapes and colours are discussed, and a written, itemised quote follows.
