Paved Blue Roofs
A paved blue roof is a type of blue roof system in which stormwater retention is provided beneath or around rooftop paving elements, such as concrete or stone pavers installed on pedestals. While still functioning as a blue roof, its storage layer sits under the paved surface, allowing the roof to temporarily hold rainwater and then release it slowly through controlled drainage.
Sika® Paved Blue Roofs
A Sika Paved Blue Roof combines a SikaShield® 2 Layer Reinforced Bitumen Membrane Warm Roof, or SikaShield® Hot Melt Inverted Warm Roof, with either Sika® RetentionRoof Water Retention Boxes (Geocells) covered with hard landscaping such as cast stone or mineral slabs, porcelain tiles or other pedestrian finishes, or cast stone/mineral slabs/porcelain tiles on paving supports, depending on the attenuation demands.
Typically used in new build construction, Sika® Paved Blue Roofs are also suitable for retrofit/ refurbishment applications with all systems specified with BBA Certification.
When installed by a Sika® Verified or Certified Roofing Contractor with Sika® NatureRoof Registered Contractors the project will be eligible for a comprehensive Sika® System Guarantee.
