Corrugated Metal Flashings & Fixings

Custom Metal Flashings also available on request. Delivery 7-10 working days.

Choosing The Right Metal Roof Flashings

Material Compatibility: Choose corrugated flashing materials that are compatible with your corrugated sheets to prevent galvanic corrosion. For instance, if your roofing is galvanised steel, opt for flashings made from the same material! See below.
Application Type: Identify the specific areas requiring the corrugated metal flashing, such as ridges, valleys, eaves, or abutments. Each area may necessitate a different type of flashing to provide optimal protection.
Visual Preferences: Select metal roof flashings that complement the colour and finish of your corrugated sheets to maintain the visual appeal of your structure.
Custom Fabrication: For unique architectural features or non-standard roof designs, consider custom-fabricated flashings to ensure a precise fit and enhanced performance.

What Screws Should I Use For My Sheets?

Important: Always evenly space your screw fixings across roofing sheets. Do not over-tighten or under-tighten your screws as this can affect the performance of the washer and prevent it from sealing correctly.

32/1000 sheets - Use 22mm stitching screws to fix flashings/sheets to other sheets. We recommend using TF32-S19 screws to fix the sheets on to purlins.

34/1000 sheets - Again, use 22mm stitching screws to fix flashings/sheets to other sheets. We recommend using TF32-S19 screws to fix the sheets on to purlins. Screws should be no more than 400mm apart when securing the flashing

13/3 sheets - Use 65mm BAZ TEK Screws which are self-drilling and self-sealing. When fixing your 13/3 corrugated sheeting, it's imperative they are fixed at the crest point. Colour caps can be used to match or contrast with the roof sheeting you are using. This is an effective way of hiding the silver screws from view. Stitcher screws at 22mm are advised for securing flashings in place

41/1000 sheets - We recommend using 22mm TF32-S19 screws which are self-drilling and self-sealing. Colour caps can be used to match or contrast with the roof sheeting you are using. Purlin spaces for tile sheets need to be 600mm apart.

Ridge Caps - Should be fixed using self-drilling TEK-type stitching screws. Each ridge should be overlapped by a minimum of 200mm.

For Flashings - The 22mm stitcher screws are advised for securing flashings in place. Screws should be no more than 400mm apart when securing the flashing.
