Lightweight vs Heavyweight Roofing Structural Cost Comparison – Oct 09
It is generally accepted that structural framing requirements for a lightweight roof are less than for a heavyweight roof and can result in cost savings. The degree of these cost savings is often debated, so the NZMRM engaged an independent consultant to look at the savings that could be achieved using a lightweight roof.
The findings are contained in the information bulletin below. The bulletin shows that significant structural costs savings are achievable when using lightweight roofing materials compared to using heavyweight roofing materials. The bulletin also provides advice and tips on how designers, builders and merchants can maximize the cost savings for their clients through using a lightweight roof.
