When does a fibre-cement roof suit a materials store?

Set limits for moisture exposure and specify how goods arrive and are packaged. Check the storage requirements issued by the goods manufacturer before deciding how many sides can stay open. Roofing alone cannot guarantee suitable conditions for every material.

Wind can act on both faces of an open shelter roof. Its location and degree of enclosure affect the loads. Design the fixings and supports to transfer these forces to the frame, paying particular attention to edges and corners. A screw pattern from a closed building may be unsuitable, even if more screws are added. Tell the designer about future side screens, since partial enclosure can change the loading assumptions.

Direct runoff away from unloading bays, pallets and vehicle routes. Water follows the corrugations, so roof slope and eaves layout matter. Keep the unsupported sheet overhang within the system limits. If the loading area needs a wider canopy, extend its supporting structure accordingly. Check gutter outlets and access for cleaning. Position or protect downpipes so that manoeuvring forklifts cannot strike them.

Set stack heights in relation to the frame, services and handling operations. Stocks must leave ventilation paths open and must not bear against the roofing. Long profiles and sheets can cause local impact damage if leaned against fibre cement during unloading. Mark handling zones so that lifted loads stay clear of the slope. Leave enough room to inspect the underside of the roof.

Identify dust and deposits produced by the goods. Check that the sheets, coatings, fasteners and accessories suit those conditions. Fibre cement does not rust like steel, but steel fixings and purlins still need suitable protection. Check cleaning products and methods against the instructions for the surfaces and joints. If deposits retain water, find out why they build up before increasing the intensity or frequency of cleaning.

Replacing one sheet may require stock to be moved and lifting equipment brought in. Identify an access route and an area to close off. Provide safe access to gutters, ridge and penetrations without walking on the fibre cement. In a full store, restricted access can make a small repair costly. Keep the profile and fixing records. Store spare sheets correctly and confirm they still match the installed system.

Include roofing, fittings, supports, drainage and site logistics. Calculate sheets from the cutting plan and effective cover. Large sheets may suit a regular roof slope while requiring particular transport arrangements. Ask whether installation can be phased to keep part of the store operating. Compare what each price buys in protection and continuity of handling for the actual flow of goods.

List the materials to be stored and draw the traffic and drainage routes. Use that information to choose the covering, decide which sides need closing and reserve access for future repairs.
