Do you need to pre-drill holes for roofing screws?

No - you generally don’t need to pre‑drill when using Cladco roofing screws. Our range includes self‑drilling TEK screws designed to drill their own hole as they fix into wood, light steel, or heavy steel. Stitcher screws can also be used for lapped areas...

How long should my roofing screws be?

It depends on which roofing sheet is being installed. The screws chosen will need to penetrate the frame beneath as well as the roofing sheet itself. We have a large range of screw lengths available to accommodate for any roofing installation.

How tight should my roofing screws be?

It’s important not to overtighten screws as this will put pressure on the washers which could potentially break them. Make sure the screws are flush to the roofing surface and make sure that once screwed, they are tight enough to hold the structure.
