Don’t Forget Your Verge Undercloak!

Often overlooked, undercloak is the most important component of a traditional verge for slate and tiled roofs. Vital for the repair and maintenance of existing roofs, the wet bedded verge is still frequently incorporated in new build designs.

Cembrit’s fibre-cement undercloak is competitively priced, consistent in thickness, which means the mortar does not crack over the joints when it dries out, and strong enough despite its slender appearance to cope with the rigours of the re-roof or new build project.

“We’re able to offer the roofing contractor the advantage of ordering slates and undercloak together,” says Ged Ferris, Marketing Manager at Cembrit. “We can also deliver any quantity of undercloak to a contractor that decides they want to purchase this commodity product separately. Collection facilities are also available at all five of our depots if customer prefers.”

Cembrits range consists of two thicknesses, 3.2mm thick x 150mm (6”) x 1.2m (4’) and 4.5mm thick x 150mm (6”) x 1.2m (4’) and 2.4m (8’). For larger overhanging verges on schools and commercial buildings etc, a 4.5mm thick x 300mm (12”) wide strip x 1.2m (4’) is available.

Having this permanently in stock at all depots means that users can take advantage of the ease of buying their slates and undercloak at the same time in the knowledge that they are benefiting from Cembrit’s excellent experience of sourcing good quality roofing products from around the world.

Using skills built up over 80 years, Cembrit select natural slate from Spain, Canada, Brazil, China, India and the countries of Western Europe. From UK quarries Cembrit offer Welsh, Cornish and Westmorland slates.
