Eagle Waterproofing Ltd

ObjectivesThe roof had reached the end of its life and needed refreshing before it deteriorated further. Much of the roof covers unheated space so no thermal upgrade (Insulation and vapour control layer) was necessary in this case.SolutionsThe existing felt was generally well adhered so with some preparation work the contractor planned to apply Ultraflex directly over the felt and finish with Ultratop.All loose mineral on the existing roof was swept away and the roof was cleared of debris. The roof was then cleaned using a jet wash and allowed to dry. All defects in the existing roof were repaired to a standard which could accept the liquid coating. Cracks were sealed with Ultraflex PU mastic and any bubbles in the felt were cut and stuck back down with a torch.Ultraflex was applied directly over the prepared felt, fully reinforced with 225GSM matting at a rate of 1.5Kg/M2. Once cured the roof was inspected for defects and a final coat of Ultratop was applied to finish.BenefitsThis roof now benefits from a 20 year guarantee backed by Eagle Waterproofing giving the customer peace of mind for the foreseeable future. The roof was refreshed and finished to a very high standard in a relatively short space of time. As a result, disruption to the business was minimal and works were far more cost effective than they would have been had the roof been replaced entirely.Project informationConstructionFactory RoofProducts UsedUltraflexUltratopUltraflex PU MasticUltraflex MattingConstructorRichmond RoofingSupplierRinus Roofing, Leeds“The system was very easy to use, the convenience of local stockists with available product and the competitively priced system meant Ultraflex was a good fit for this refurbishment scheme.”Mark Cooling, Richmond Roofing
