Corrugated Bitumen Roofing Sheets - Green
(please note: due to screen resolution colour may vary from that displayed)
Sheet size 950mm (wide) X 2000mm (long)
Corrugated Bitumen Sheets are ideal for use in agricultural buildings, sheds animal housing and industrial roofing applications. The sheets provide an excellent dimensional stability and in time develop a full intense colouring through the natural oxidation of the bitumen. The sheets are extremely light and flexible whilst still incredibly strong. They are resistant to external agents and acids and are 100% asbestos free.
Sheets are supplied with a 15 year warranty covering the waterproofing of the product.
Extended lead time of up to 10 working days delivery may be applicable on this product.
Laying Instructions
Preparation of the roof prior to laying:
Any pitch below 10 degrees should be boarded with an appropriate plywood or similar.
For pitches above 10 degrees the following batten spacings should be used.
For a loading of 200kg/m² battens should be spaced at 460mm centres.
For a loading of 350kg/m² battens should be spaced at 310mm centres.
It is recommended to impregnate all of the timber that makes up the the supporting frame of the roof.
Lapping of the panels:
Side lap - one corrugation
Head lap - minimum of 150mm
Fixing the sheets:
Sheets should be secured using our zinc plated bitumen fixing nails. Two rows of nails should be driven in parallel to the direction of the head and at each side of the sheet. Nails should be driven in to the crown (the uppermost part) of the sheet. Subsequent rows of nails should be used every third corrugation.
Sheets should be layer as per the diagram below.
Ventilation:
To ensure adequate roof ventilation, ensure the sheet ends are at least 50mm from the roof apex. This will allow air to pass through the eaves, through the bat tern cavity and up to the rooftop. This constant flow of air will avoid the formation of mould and mildew and help control condensation.

Important: Deliveries of our large items (polycarbonate, canopies, corrugated sheet etc) are made on vehicles of up to 18 tonnes in size (which as a guide, is a little larger than the average bin lorry). If you should have ANY delivery restrictions such as weight, height or width or if you live in a rural location with a single track road or a road with tight turns PLEASE INFORM US AT THE POINT OF PLACING YOUR ORDER. We can then try to allocate a smaller vehicle to your delivery.
DO NOT BOOK YOUR BUILDER / TRADESMEN UNTIL YOUR ITEMS HAVE ARRIVED ON SITE. Unfortunately deliveries can and do go wrong from time to time. We cannot be held responsible for any costs arising from cancelled labour due to late deliveries.
Very large sheet and heavy items (such as 2100mm X 4000mm and above) may be subject to extended lead times (dependant upon location), and will require you to be on site to offload the delivery with the driver.
Please note: Most of the large items we deliver are too big for the 'normal couriers' i.e. Yodel, Parcelforce, DPD etc., this means that in some circumstances the lead times for orders may be extended dependant upon location.
All deliveries made from ourselves, or carriers delivering on our behalf are available to Mainland United Kingdom ONLY. Please contact us if you require deliveries to other areas of the UK. Certain areas of the Highlands of Scotland and Mid Wales also carry a delivery surcharge and/or are subject to extended lead times.

Please note: ALL polycarbonate, glazing bars, corrugated PVC sheet, corrugated bitumen sheet and canopies may require a signature upon delivery however, unless specifically requested in writing from the purchaser at the time of order goods may be left in safe place by the delivery company. If you DO NOT want goods to be left without a signature you must inform us at the point of ordering. As most of the deliveries are made by one delivery driver, sometimes with deliveries of larger items you may be required to help the driver with the unloading of the material.
Unfortunately sometimes goods do get damaged in transit. If goods appear to be damaged on delivery please ensure that you sign the paperwork 'DAMAGED' as claims for damaged goods cannot always be accepted if the paperwork has been signed as received "in good condition". Signing 'unchecked' is not an acceptable method of signing the delivery note. Please see our terms and conditions for more information concerning damaged material found here.
IMPORTANT STORAGE INFORMATION
We send most products wrapped in protective packaging to avoid damage during transit. When the delivery has arrived you will need to remove the outer packaging. DO NOT store plastic products in direct sunlight. Products stored in the plastic outer packaging and/or in direct sunlight, particularly in the summer months, can warp making the product unuseable. Products damaged due to improper storage will not be accepted as ‘damaged’.
Should you have a specific request concerning your delivery we will do our best to accommodate you. Please contact us if you require any help or have any specific requests.
