STORAGE AND HANDLING Provision should be made for proper storage and handling of materials to avoid deterioration in quality and appearance, to avoid breakage or distortion, and to minimise wastage. GENERAL 1 Store roof underlays on end on a firm, clean base protected from direct sunlight and in accordance with manufacturers' instructions. 2 Store battens and counterbattens on sufficient bearers to prevent sagging or twisting. 3 Protect battens and counterbattens from water saturation when stored in bales or bundles horizontally. 4 Store roof accessories in a safe, weatherproof...

LOADING OUT GENERAL 1 Before tiling commences, check delivered products against initial order and report any discrepancies or defective materials to the site agent or manufacturer. 2 Pallet loads should be checked for batch codes to ensure consistency on large roof areas. 3 Special fittings should be checked against matching tiles to ensure suitability before tiling commences. LOADING THE ROOF WITH TILES OR SLATES y Load slates, tiles and fittings out on roof safely, support by battens to avoid slippage and distribute evenly to prevent overloading of roof structure (Figs. 1-2). y All slates...

2 Minimise gap at laps resulting from different tautness between underlay courses. Drape in underlay between supports to be no less than 10mm and no greater than 15mm. 3 Fix underlay with fixings specified, keeping number of perforations to a minimum. 4 Handle and fix underlay with care to ensure no tears or punctures. Repair any tears or punctures prior to tiling. 5 Ensure that underlay does not obstruct flow of air through ventilators located at eaves, ridge or in main roof. 6 Weather appropriately all holes formed in underlays for soil vent pipes etc. 7 A nominal 10mm drape should be...

UNIVERSAL UNDERLAYS Marley underlay can form part of our complete 'Roof System' and should be laid horizontally across the rafters, starting at the eaves. It should not be stretched taut over the rafters, but draped as shown, in order to allow for small temperature movements and to ensure a gap between the tile batten and underlay for drainage down to the gutter. Marley vapour permeable underlay must always be fixed with the PRINTED side facing outwards. Seal laps with integral tape.

General advice

BATTENS CHOOSING BATTENS 1 Roofing battens must meet the recommendations stated in BS 5534 in terms of their species, permissible characteristics and defects (knots, fissures and splits, wane, slope of grain, rate of growth, distortion, decay and insect attack, sap stain, resin pockets and moisture content), including minimum dimensions and grading requirements. 2 To help meet these minimum standards, roofing battens delivered to site should be graded with the following information in accordance with the standard: a) Name of supplier (the company that graded the roofing battens NOT the...

CHOOSING COUNTER BATTENS 1 It is important to note that counter battens need not be marked or graded where they are fully supported by the rafters. In cases where they are used to restrain insulation boards and are subject to upward bending loads they should be graded. 2 However, if counter battens are used to provide a ventilation gap beneath the roof covering, there is a potential risk of high levels of moisture, and it may be advisable for them (and the roofing battens fixed above) to be preservative treated in order to provide the required durability. RECOMMENDED BATTEN SIZES (BS 5534)...

JB-RED BATTENS JB Red battens, available from Marley, and part of our complete ‘Roof System’ are a sure way of ensuring compliance. They not only fully comply with BS 5534, but are also recognised by third party conformity certification. Each batten is laser scanned and graded prior to delivery, providing all the assurances required to comply with the British Standard – ensuring the highest quality of batten available with the least waste and lowest risk to health and safety. The Red colour means that JB Red battens are highly visible on site, therefore Local Authority Building Control,...
