Thatch Roof Area Calculator
Estimate the size of your new lapa, gazebo, rondawel or thatched roof in minutes. Simply enter your dimensions, choose the roof shape and roof pitch, and instantly calculate both the footprint and total roof surface area.
Vigo Thatching has been designing and constructing quality thatched roofs throughout Gauteng and South Africa for many years. This free calculator is designed to help homeowners, architects and builders estimate roof areas before requesting a quotation or planning materials.
Getting Accurate Measurements
For the most reliable results, measure from the outside edge of the thatch to the opposite outside edge of the roof. This method automatically includes the complete roof surface and provides a far more accurate estimate of the area used for pricing and material calculations.
Suitable for
- Garden lapas and entertainment areas
- Rondawels and circular thatched roofs
- Free-standing gazebos
- Residential thatched homes
- House extensions and verandas
- Commercial lodges, restaurants and hospitality projects
Select the roof shape below, enter your dimensions in metres and choose the roof pitch. The calculator will display both the footprint area and the estimated total roof surface area in square metres.
Calculate Your Roof Area
Professional Measuring Tips
- Measure from the outside edge of the thatch to the opposite outside edge for the most accurate roof area.
- For existing roofs, measure the actual roof rather than the building footprint wherever possible.
- Round structures such as rondawels only require the overall diameter.
- Complex roof designs can be divided into simple shapes and calculated separately before adding the totals together.
- This calculator provides an accurate estimate for planning and budgeting. For final quotations, Vigo Thatching carries out professional site measurements.
