A verandah gives a Box Hill home a roofed outdoor space that keeps working when the weather turns. Scoresby, the nearest long-record Bureau of Meteorology station with sunshine and wind records, averages about 850 mm of rain over roughly 115 wet days a year, well above the western suburbs, so a roof that sheds water cleanly matters here as much as summer shade. Peak Pergolas designs and builds flat, gable and curved verandahs across Box Hill, Blackburn, Mitcham, Vermont, Burwood and the rest of Whitehorse. Each one is measured at the house, drawn to suit its roofline, set on footings sized to a soil test and lodged for a building permit.

Verandahs in Box Hill 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 clears rain.
A flat roof verandah is not truly flat: it runs at a low pitch so water drains to a gutter on the outer edge. It is the most economical shape and suits single-storey homes with a low eave, or long runs across the back of the house. Colorbond corrugated or trimdek sheeting is fixed to purlins over a steel or timber frame, and the fall is set so water never ponds on the sheets.
A gable verandah rises to a central ridge and suits homes with a pitched tiled roof, which covers most of the interwar and post-war houses in Box Hill and Box Hill North. Drawn to the same pitch as the house, it looks like part of the original building. The raised centre lifts the ceiling, lets warm air rise away from the table, and the infill triangle can be left open, battened or glazed with clear sheet to let in the low winter sun.
A curved or bullnose verandah uses sheets rolled to a smooth arc. It is the traditional look on the front of an older home and softens the line of a plain modern facade. The curve sheds water off the front edge and is lighter on the eye than a gable on a narrow block.


A verandah does a different job at the front of a house than at the back. The front one is about shelter at the door and how the house looks from the street. The back one is about turning the alfresco into a room that is used all year.
Much of Box Hill and the older parts of Blackburn and Surrey Park filled with houses between the wars, after Box Hill became a borough in 1925, and kept growing through the 1940s and 1950s. Many of those homes have lost an original front porch or carry a later add-on that has sagged. A new front verandah is drawn to the proportions of the house, with posts spaced to the windows and a roof shape that suits the period. Because a front verandah sits forward of the front wall of the house, Whitehorse City Council's rules require a building permit for it, and the drawings are prepared with that in mind.
At the back, a verandah covers the slab or deck outside the kitchen and living room, giving a dry place for the table, the barbecue and a clothes line in wet weather. It can be attached to the fascia or raised above the gutter on fly-over brackets where the eave is low, so the new roof clears the existing one and adds height. A larger area can use heavier beams so long spans run without posts in the middle of the space.
Scoresby records about 3.9 hours of sunshine a day in June, against 8.8 in January, so a solid roof over a south-facing or narrow back yard can leave the kitchen dark through winter. The roof can be made partly or wholly of clear or opal polycarbonate, a gable can have a glazed end, or the verandah can be set higher so more sky reaches the windows. The aim is cover from rain without losing the winter light inside.
A verandah lasts when the frame, the roof, the footings and the connections are all chosen for the site. In Whitehorse the deciding factor is water.
Rain at Scoresby averages 851.9 mm a year over about 115 days with at least 1 mm, with May and October the wettest months at around 84 mm each. A verandah roof here deals with long spells of steady rain, not just the odd storm, so it is set with a positive fall, the gutter is sized for the roof area and runs the full low side, and the downpipe connects to the stormwater system instead of emptying onto the paving next to the back door. Where the verandah meets the house, flashing is cut into the wall or fixed under the existing gutter so the join stays dry.
Every post sits on a concrete footing, and its depth and width follow a soil test that sets the AS 2870 site class for the block. The footing is designed for that class, so the verandah does not move with the ground through wet winters and dry summers. Posts sit on galvanised stirrups or base plates clear of the soil, so timber stays dry and steel does not rust at the base.
Galvanised steel frames span further with fewer posts and need no oiling. Treated pine or hardwood suits older homes where timber matches the house. Steel frames are powder-coated or Colorbond-finished so the posts and beams match the roof, and timber frames are sealed or painted before the roof goes on. Either way the roof is usually Colorbond steel sheet in a colour chosen to match the gutters and trim, fixed with screws at the spacing the engineering calls for.
Whitehorse City Council's rules require a building permit for any structure attached to the house, any roof area over 10 square metres and any structure forward of the front wall, which covers almost every verandah. Footing, beam and wind engineering is prepared with the drawings, the property is checked on Whitehorse Maps for overlays that might need a planning permit first, and the application is lodged as part of the job. See pergola permits for how the rules work.


Every verandah is priced from a free measure and a written, itemised quote, because no two houses and yards are the same. The main things that move the price are listed below, so a quote can be read line by line.
Area is the biggest factor: more roof means more sheets, purlins, beams and gutter. Shape comes next. A flat roof is the most economical, a curved roof costs more because the sheets are rolled, and a gable costs more again for the ridge, the extra framing and the infill. Clear sheet sections, a glazed gable end or an insulated roof are priced as their own items.
A level back yard with side access is the simplest site. A sloping block needs taller posts at the low end and sometimes stepped footings. Where an old verandah or pergola has to come down first, removal and disposal are shown as a separate line, along with any repairs to the fascia or gutter it was fixed to. Permit drawings, engineering and fees are also listed separately, so nothing is hidden inside a single total.
Verandah, pergola and patio are often used to mean the same thing, but they are different structures with different jobs, and the right one depends on how the space will be used through a Whitehorse winter.
A verandah has a solid roof and is usually attached to the house, so it keeps rain off the space and the wall below. A timber pergola or aluminium pergola has open rafters or battens that carry a vine or shade cloth, giving filtered summer shade but no rain cover. A patio roof is a solid roof over the back slab, the same idea as a back verandah. A louvre roof sits between the two, with blades that open for winter sun and close for rain. With 115 wet days a year here, most families who want to use the space in winter choose a solid or opening roof.
Verandah kits come in set sizes and suit a simple, level site. A site-built verandah is measured and drawn for the actual house, so the pitch matches the roof, the posts land where they are wanted, the gutter connects to the existing stormwater and the engineering suits the block. On older homes, where fascias are rarely straight and slabs are rarely level, that fit is what stops leaks at the join.


A visit to measure the house and the yard, talk through materials, roofs and colours, and then a written, itemised quote.

Drawings and engineering are prepared for the site, overlays are checked and the building permit is lodged.

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 roof is the most economical, a curved roof costs more, and a gable roof costs more again. Removing an old structure, a sloping block and clear or insulated sections add to the price. A free measure gives a written, itemised quote.
Almost always. Whitehorse City Council's rules require a building permit for any structure attached to the house, any roof over 10 square metres and anything forward of the front wall. Some properties also have overlays that need a planning permit first. 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 and approved. Once the permit is issued and materials arrive, a typical verandah is built in a few days, depending on its size, the weather and the site.
It can, especially in winter when Box Hill gets about four hours of sun a day. Clear or opal polycarbonate sections, a glazed gable end or a higher roof line let more light reach the windows while still keeping rain off the outdoor area.
A flat roof suits single-storey homes with a low eave and long runs across the back. A gable suits homes with a pitched tiled roof and gives more height. A curved roof suits the front of an older home. The free measure looks at the house roof and the space before a shape is recommended.
The area is measured, along with the fascia height, the pitch of the house roof, the window and door heads and the fall of the ground. Roof shapes, materials and colours are talked through, and a written, itemised quote follows.
