Belfast Roofing Supply Centre

Belfast Roofing Supply Centre is a roofing merchant in Belfast, supplying roofers, builders and homeowners across Northern Ireland. We are the supply side of Prentice Roofing LLP, a roofing contractor since 2010, so everything on these shelves is something we have used on a roof ourselves.

We specialise in flat roofing: EPDM rubber membrane cut to your roof size, TRC adhesives, trims and outlets, and the full OWL Lava 20 liquid rubber system. We also carry the pitched roofing side in depth, with slates, tiles, ridge and dry verge, lead and flashings, underlay, battens, ventilation and tools. Our EPDM calculator prices a complete roof in about a minute, and you can order online, or call in to the trade counter at Carrowreagh Business Park and talk it through with someone who has laid it.
