Buy Flashings Buy Corrugated Sheets

Box profile roofing sheets are fixed in the valleys, straight through the sheets. The seal is provided by a long life neoprene washer which will last up to 30 years.

The calculation for the number of fixings you will need is this:-

Number of fixing points x 4 (fixings per fixing point) x number of sheets

Fixings are supplied in bags of 100. Caps are available to suit the colour of the sheets you’ve chosen.

Fixings are available for fixing into 3 different types of material:-

1. Timber
2. Light Section Steel (up to 3.2mm thick)
3. Heavy Section Steel (up to 12mm thick)

Timber Fixings

Timber fixings have a needle point which will drill straight through the sheet without the need to pre-drill.

For single skin sheets, fixing lengths of 25mm, 32mm and 45mm are the norm. The length you select is dependent on how far you want the fixings to penetrate.

Lengths up to 150mm are available should your application need it.

Timber Fixings 25mm (Bag of 100)

£11.00 (£13.20 incl. VAT)

Timber Fixings 32mm (Bag of 100)

£11.00 (£13.20 incl. VAT)

Timber Fixings 45mm (Bag of 100)

£15.00 (£18.00 incl. VAT)

Light Section Steel

Light section steel is classed as being up to 3.2mm thick.

These fixings will cut a hole through the top sheet and metal purlin without pre-drilling, tapping the hole to ensure a secure fix.

For single skin, a 25mm long fixing is ideal although lengths up to 235mm are available. These fixings can be used into timber as long as they penetrate more than 50mm into structural grade timber.

Light Section Steel 25mm

£11.00 (£13.20 incl. VAT)

Heavy Section Steel

Heavy section steel is from 4mm to 12mm thick.

These fixing are hot rolled with means they will cut through and tap without pre-drilling.

Lengths of up to 245mm are available.

Heavy Section Steel 25mm

£18.00 (£21.60 incl. VAT)

Stitcher Fasteners

Stitcher fasteners are for metal to metal applications. This includes fixing flashings and securing the side or over laps of the sheets to create a water tight seal between sheets.

To calculate the number of flashings, we would suggest 12 stitchers per flashing. If you are using butyl to seal the side laps or sheet joins, divide the total number of metres you have by 0.4m. This will give you the number of stitchers you will need at 400mm intervals.

Butyl Tape

Size: (Roll – 15m x 9mm x 3mm)

Butyl tape gives a long lasting, strong and flexible weather seal, being able to flex with the normal contraction and expansion of metal roof cladding. Used in compression joints, guttering assembly and with roof fillers, butyl ensures your roof will remain water tight for the long term.

To calculate how many rolls you’ll need, divide the total meters of your roof by 15 and round up to the next whole number.

Butyl Tape (Roll – 15m x 9mm x 3mm)

£3.95 (£4.74 incl. VAT)

Standard Fillers

Standard fillers are supplied in pairs, with the small flute sitting under your metal cladding at the gutter end, and the large flute sitting on top of the cladding and under the flashing at the top ridge.

They can be set into a bead of silicone or butyl tape to ensure a good seal.
