Roofing fixings that match roof colour while resisting corrosion and leaks. Professional installers and DIYers get a watertight seal and faster installation with Keple Roofing Screws. Are these the right long-term fixings for your roof?
⚡ At a Glance
- • Corrosion Resistance: Zinc plated steel (12µm) with RAL powder coating (60–80µm) for outdoor durability
- • Best for: Roofers and DIYers fitting thin metal roofing and cladding to timber frames
- • Not ideal for: Heavy structural steel or load-bearing applications that need larger fasteners
Hex-head, self-drilling roofing screws with EPDM sealed washer and hardened coarse threads. Colour-matched RAL coating and zinc plating support outdoor use and visual integration with roof panels.
Watertight roofing joints – with EPDM sealed washer
EPDM washer compresses around the hex shank to form a durable seal against moisture while accommodating thermal movement. The washer is specified to resist over-tightening or under-tightening during installation.
Ensures reliable watertight joints at each fixing, reducing the risk of leaks and water ingress around roof fastenings.
Faster installs on thin steel – thanks to self-drilling tip
Hardened self-drilling, self-tapping tip drills through typical roofing steel in under two seconds, eliminating the need for pre-drilling. Coarse threads then secure into timber frames such as hardwood and softwood.
Speeds up installation and cuts labour time, especially useful for long runs of panels or tight schedules.
Long-lasting finish and colour match – with zinc plating and RAL powder coating
Zinc plated steel at 12µm meets high corrosion protection standards (LST EN ISO 12944-2:2000) while the RAL powder coat (60–80µm) delivers UV-resistant colour that resists damage during handling and installation.
Maintains a neat, integrated appearance with the roof while extending service life in outdoor conditions.

❓ Frequently Asked Questions
Q: Are these screws self-drilling or do they need a pilot hole?
A: Self-drilling tip drills through the steel in less than two seconds, so no pre-drilling is required for typical roofing panels.
Q: What driver or tool is needed to install the screws?
A: An SW 8 hex nut driver is required for installation and is compatible with common hex nut driver tools.
Q: Will the EPDM washer prevent leaks around fixings?
A: The EPDM sealed washer protects against moisture ingress and reduces the effects of thermal movement, helping to maintain a watertight joint.
