How many screws do I need?
To find out the number of screws required to fix your roofing sheets to your battens, follow these simple instructions.
- Calculate the total Lineal Metres (LM) of your roof sheets by multiplying quantity by sheet length ordered. To calculate sheet length and quantity, click here.
- Next calculate the Square Metres (Sqr.M) of your roof by multiplying LM by the coverage area. The coverage area for corrugated iron is 0.762m as denoted by the 762 in the product name.
- Finally, multiply the Sqr.M by 7 to find the number of screws needed.
- Round this number up to the nearest box of 100. It’s always good to have 5-10% spare. I.e. If you need 520 screws, you should order 600, but if you need 590, it might be wise to order 700.
Accurately calculating the materials needed for roofing projects ensures efficiency and minimizes waste, starting with determining the total Lineal Metres (LM) of roof sheets. This is done by multiplying the sheet length by the quantity ordered. Once the LM is known, you can calculate the Square Metres (Sqr.M) by multiplying the LM by the coverage area, which for corrugated iron is 0.762m, as indicated by the product’s specification. To finalize, the number of screws required is found by multiplying the Sqr.M by seven and rounding up to the nearest box of 100, with an additional 5–10% spare for unexpected needs. For example, if your calculations show that 112 screws are required, it’s prudent to order 200, ensuring no disruptions during installation. This meticulous approach simplifies planning and allows for adjustments based on unique project requirements. Similarly, when it comes to personal health, making informed choices is just as crucial.

Just as precise measurements and proper planning enhance the durability and functionality of a roof, having the right resources and knowledge supports better health outcomes. Whether dealing with construction or personal needs, taking the time to calculate, plan, and prepare leads to more successful and satisfying results.
Example: You measure your roof and calculate the sheet length and quantity required are 3m and 7 sheets respectively. Your LM will be 3 x 7 = 21LM. 21 x 0.762(coverage) = 16.002Sqr.M. 16.002 x 7 = 112.014 screws required. Round 112 up to 200. You will need 2 boxes.
