Roof fixings - screws and screw caps
Using the correct screws is essential for ensuring the roof is secure, and it’s important to use quality cladding screws to ensure they can withstand considerable wind pressures and other environmental factors. Please note that the TEK carbon steel roofing screws are designed to work with different materials, and you’ll need to ensure the correct cladding screws are being used for a secure connection. If you are unsure which roofing screws you need, read our fixing guide or get in touch with us directly.
Self-drilling TEK cladding screws that incorporate a 5/16th hex head and a stainless steel and neoprene bonded saddle washer are used to fix sheets to wood or metal purlins in the lower section of sheet profiles. Longer screws of up to 175mm in length are available for fixing through insulation materials or composite panels. These roofing screws include heavy section, light section and < a href="/roof-fixings-and-accessories/screws-to-wood-with-a-19mm-bonded-washer-pack">timber purlin.
TEK screws in a 65mm length with BAZ washers are used for corrugated sheeting to fix through the top of the corrugation into timber purlins.
Self-tapping or ‘stitching’ TEK screws are available for fixing trims to a metal sheet, or sheet to sheet on laps.
Colour caps are used to cover screw heads for a seamless, professional look. These coloured roofing screws covers provide a colour matched finish in over a dozen shades.
