The existing roof covering consisted of 20mm asphalt with solar chippings. The substrate was concrete and was uninsulated at roof level.
The asphalt was old and brittle. During thermal movement the asphalt had split and was allowing rainwater to penetrate and ingress into the rooms below. Localised repairs were not possible due to the solar chippings being embedded into the existing asphalt.
London Roofing removed all of the loose solar chippings. Those that were embedded were ground down flush with a floor planer. We then installed a cold applied liquid membrane and incorporated an anti-slip walkway for maintenance access. The job was problematic due to the noisy works being carried out directly above the hotel bedrooms. Close liaison with the hotel management allowed us to complete on time and within budget. A 20 year single point labour and materials guarantee was issued on completion.
