Storage Building Roof Specification

urbanspec bin and bike stores are designed for ease of specification either pre-engineered or bespoke. The configurable approach extends to roof design systems where there are a number of factors to consider including site security requirements, planning conditions and biodiversity net gain considerations.


In standard configuration, urbanspec bin and bike stores have a profiled steel roofing system. An enclosure only specification is available where site conditions do not require a roof covering.


External bin and bike stores are ideally suited to green roof applications, helping increase biodiversity on new developments, increasing CO2 capture, reducing rainwater run-off and enabling the softening effect of nature on the urban landscape.


Specified with either extensive or intensive lightweight green roof systems, urbanspec H-Series extensive systems support primarily sedum plants, while the intensive version with an increased substrate depth, supports a mix of sedum and wildflower plants.

There are five urbanspec Roof Design Systems:

  1. urbanspec H-Series Standard Steel Profiled Roof System
  2. urbanspec H-Series Steel Profile / Fire Resistant (FR) Liner Roof System
  3. urbanspec H-Series Green Roof System (Intensive)
