Installation and system requirements
Choose the drill point, thread, length and washer for the full build-up. Use the specified installation method and fixing pattern without over-compressing sealing washers.
How to estimate the requirement
Count fixings from the approved roof layout and support lines. Include separate fasteners for flashings and accessories where required.
Care and inspection
Inspect loose fixings, damaged washers and corrosion during safe roof maintenance. Replace with the correct compatible specification.
Request the right quotation
Send the project location, building use, dimensions or drawings, preferred finish and whether you need supply only or installation support. ReZa will confirm the product variant, quantities, accessories and delivery scope. Any indicative price excludes unconfirmed project-specific items; GST, freight and installation are confirmed in the quotation.
MATERIAL AREA ESTIMATOR
Plan the square footage before the quotation.
Enter a known surface area or use roof length and width. Add slope, deductions and a project-specific allowance to estimate material coverage.
- Use actual roof-slope length when available; then leave slope at zero.
- Openings, laps, cuts and accessories vary by system and roof geometry.
- Final quantities should be checked against drawings or a site survey.
