Create an attractive and functional outdoor living area that will enhance your home and lifestyle with the smooth, simple, uncluttered lines of the classic Stratco Outback Flat Roof.
This versatile Flat Roofing system can be configured to cover any area around the home.
Adapt the versatile Stratco Outback Flat Roof to suit your lifestyle
The Stratco Outback Flat Roof system is extremely versatile and can be configured to cover any area around the home.
It is ideal as a single unit or can be incorporated with a gable roof, curved roof, or pergola system for extra cover.
Available as a freestanding structure or attached to the home, it can be used as a carport, verandah or patio.
With the addition of Outback Rooflite, you can supply filtered light to the underside.
The beams can span up to 8.4 metres and are available in either 120mm or 150mm sizes.
Four configurations – Giving you choice and control
There are four Stratco Outback Flat Roof configurations to choose from:
- Type 1 Has a 4.5 metre maximum span and only requires an outside beam to support the structure. However most units use perimeter beams on all sides to provide the best appearance.
- Type 2 Is the same as Type 1, but also has an overhang at the front to increase the covered area to 5.4 metres.
- Type 3 Has support beams across its span so roofing sheets can run horizontally for a different appearance.
- Type 4 Has extra support beams and a purlin through the middle to give a span of 8.4 metres.

Design Considerations
Gable or curved units attached between a flat unit and an existing structure
Gable or curved units which are attached between a flat unit (excluding pergolas) and an existing house, are only be considered attached if the gable or curved unit is attached to the existing house (C) for its full length (L) and the longest side of the combined unit (B) does not exceed twice the gable or curved unit length (L). The flat unit in this case can be considered attached. This style requires all coloumns to be embedded into footings.

Gable or curved units attached to a flat unit on one or both sides
Gable or curved units which are attached on one or both sides to flat units, (excluding pergolas) must be attached to a house for at least 75% of the gable or curved opening length (O) to be considered attached. Flat units must be deemed attached as detailed in the flat unit section below to allow the gable or curved unit to be considered attached.

Gable or curved units are considered attached on both sides if both the flat 1 and 2 comply with the attachment rules for flat units as detailed below. Gable or curved units are considered attached on one side if only one flat unit exists and it complies with the attachment rules for flat units as detailed below.
Flat units
A verandah, patio or carport is deemed to be freestanding unless it is attached to an existing house (C) for at least 75% of the length of its shortest side (A), and its longest side (B) does not exceed twice the length of its shortest side.

Design Options
When designing an Outback Patio, consideration should be given to both the roof sheet direction, and the orientation of any openings and overhangs involved. These are often determined by appearence and drainage requirements. Some of the normal configurations are shown below. Contact Stratco if assistance is required.
