The roof is often a forgotten element on most buildings. When designed and built as a multi-functional element, a roof space can be made cost effective, provide significant environmental contributions, and create aesthetically pleasing, versatile, and usable outdoor spaces.
Roofscapes® are sustainable roofing & landscaping systems that offer the owner and society many environmental benefits, low lifecycle costs, and government incentives. These assemblies are designed to turn unused space into a park-like garden setting with a keen sensitivity to environmental enhancement.
Combining our 90+ years of roofing & waterproofing expertise with retained horticultural technology, Barrett has partnered with the most prominent suppliers of pavers, vegetation, growing media, and more to offer building owners a top-to-bottom solution for their ideal green roof.
Proven Performance
Barrett Company works with our Approved Contractors to provide two time-proven waterproofing systems that form the basis for moisture protection in our Roofscapes assemblies, Ram Tough 250 and Black Pearl Waterproofing. Each system utilizes a reinforced fluid-applied rubberized asphalt membrane.
Custom Solutions
Because we are not tied to only one approach of vegetative system, building owners and specifiers can choose among the options that will best suit their individual needs and budget.
Single Source Warranties
We offer complete assemblies with up to a 25-year single source labor and materials warranty, covering waterproofing, thermal performance, overburden removal, concrete paver warranty and renewable vegetation warranties.
ROOFSCAPES® SYSTEMS
Roofscapes® Systems are comprised of two distinct yet complementary approaches to maximizing rooftop and structural deck performance.
Terra-SCAPES™ systems are engineered for living, vegetative environments, ranging from lightweight extensive green roofs to intensive landscapes and urban agriculture. These assemblies deliver environmental benefits such as stormwater retention, improved insulation, reduced heat island effect, and enhanced aesthetics.
Examples of Terra-SCAPES™ assemblies include:
- Intensive
- Extensive
- Lawn
- Sloped
- Urban Agriculture
- Modular
Plaza-SCAPES™ systems are designed for hardscape and amenity-driven applications—such as roof terraces, paver decks, and occupied plazas—where durability, accessibility, and architectural finish are key. These assemblies protect the underlying waterproofing while supporting pedestrian traffic, furnishings, and active use, ultimately turning rooftops into functional, revenue-generating spaces.
Examples of Plaza-SCAPES™ assemblies include:
- Roof Terrace
- Amenity Deck
- Paver & Pedestal
- PMR / IRMA®
- Planter Box
