Fixings

Get a Quote

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)

Screws

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. 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. 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. 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.

Fillers (Pair)

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.

Vented fillers are used when your sheets are supplied with Dr!pStop Anti-condensation fleece.

They ensure ventilation high up within your building so that moisture laden air can be vented out.

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.

Colour Coded Caps (Bags of 100)

Caps are included in the cost of your fixings. We will automatically send you them. Only order caps here if you need more caps than the fixings you are ordering.

Roof Sheet Fixings – More Info

What are Roof Sheet Fixings? – The first thing to know is that there are many different types of roof fixings. However, they all essentially perform the same job, holding on the steel roof sheets on the bars and trusses. When first installed, the head of each fixing is separated from the roof sheet by a rubber washer. At Rollaclad, we can supply a wide range of high-quality self-drilling tek screws which make easy work of fitting sheets to timber, heavy or light metal and concrete. The Roof Sheet Fixings are fixed in the valley of the sheets where the water runs on box profile and tile effect sheets, and in the top
corrugation on corrugated sheets. This allows them to become water-tight with the rubber washer at the back of the fixing.

What Roof Sheet Fixings do we offer?

We offer a range of standard roof sheet fixings including:
• Timber Tek Fixings – these are perfect for timber batons, purlins, sterling boards, and
marine ply. As standard, they are 32mm long with 8mm hex head (available up to 45mm in
length).
• Light Metal Tek Fixings – for use in fixing sheets to galvanized z-purlins up to 3mm gauge
25mm long with small cutter 8mm hex head
• Heavy Steel Tek Fixings – for use with angle iron / box channel & heavy gauge purlins up to
6mm gauge. 38mm long as standard with large cutting tip and 8mm hex head (longer
lengths available).
• Blue Concrete Tek Fixings – for fixing sheets and abutment flashings into concrete
32mm long as standard with 8mm hex head (longer lengths available).
• Stitch Tek Fixings – for fixing sheet overlaps (sheet to sheet) and fastening all types of
flashings to steel sheets. 22mm long with small cutting tip and 8mm hex head.
• Big Six / Double Six Fibre Cement and GRP Tek Fixings (a modern alternative to hook
bolts) for use with timber batons / purlins or light metal purlins. Up to 150mm long with
large baz rubber washer to provide a weatherproof seal on curved edges.
• Hook bolts / J bolts – for use on right angle metal beams / tubing / concrete prefabs 120mm long as standard with large rubber washer (longer lengths available).

With the exception of hook bolts, all of our roof sheet fixings are generally sold in bags of 100 or boxes of 1000 with colour coded caps to match the colour of the roofing sheets. However, we also offer many other fixings on request so please feel free to contact us for more details and we will try to help you out and find what you are looking for.

What are the benefits?

• Quick and easy installation.
• Huge labour-saving costs.
• Stops water penetration and wind uplift.
• Dramatically increases roof lifespan.
• Leaves a maintenance free finish.
• Permanently secures slate/tiles & ridges on roof.

The box section sheets were delivered on time and the delivery driver was very helpful by helping to move the sheets from he front of the property to the rear garden.
The roofing sheets were perfectly cut to the size ordered and the supplied fittings were sufficient for the re-roofing job. One sheet was found to have minor distortion along one edge, possibly caused during its transport, but I did not spot this until after the driver had departed. It required gentle bending back into shape and is hardly noticeable now that it is fitted.
Overall, very good quality product and straightforward dealing with the company.

Response from the owner 14:23 13 May 25

Thank you for your feedback Frank! I am sorry to hear about the slight damage to one sheet. If there is anything we can help you with, please feel free to give us a call.
