Find your roof
Start with where the roof will work. We recommend the right sheet, length and colour, estimate the quantity and connect you with a trained installer.
Step 1
Where will the roof work?
Pick the use. Each card opens full details, and Get Quote pre-fills the request for you.
Step 2
Choose length and colour
Match the sheet length to the rafter span so joints are few and cutting is minimal.
Measure the slope
Measure from ridge to eave along the slope, and the total length along the eave. Add an eave overhang so rain clears the wall.
Pick the length
Choose from 2 to 10 RFT. A slope of about 2.4 m suits a single 8 RFT sheet; longer slopes use two rows with an end overlap.
Pick the colour
Natural grey for farms and industry, or red, blue and green from the coloured range for homes and public buildings.
Add ridge and fixings
One ridge panel run along the apex, plus hook bolts and sealing washers for every purlin crossing.
Step 3
Estimate how many sheets
A quick planning estimate for one roof slope. Your dealer confirms the exact quantity from the drawing.
Step 4
Before you buy
A short checklist that avoids most roofing problems.
- Roof slope is enough for drainage (steeper in heavy-rain districts)
- Purlin spacing matches the sheet length and expected wind load
- Side overlap of one corrugation, end overlap of 150–200 mm
- Fixings go through the crest of the corrugation, never the valley
- Ridge ventilation planned for cattle and poultry sheds
- Sheets stored flat, dry and off the ground until fixing
- A trained installer from an Anwar dealer does the fixing
