Green Roof Systems

First and foremost when installing a Green Roof you need to make sure you have a strong and durable membrane underneath. Single ply membranes such as rubber or liquid simply are not enough to keep plant roots at bay. At Design Roofing, we specialize in the installation of modified bituminous sheet (S.B.S) membranes ensuring your green roofing project is done properly from the start.

Vancouver and Lower Mainland Commercial Green Roof Systems

Design Roofing offers expert installation combining synthetic and organic green roof materials to achieve an energy efficient, long lasting commercial roof system.

Commercial Roofing in Vancouver and the Lower Mainland is moving into an era of environmentally conscious commercial roofing and construction. Design Roofing is at the forefront of this green roof movement, being Vancouver and the Lower Mainland’s Green Roof System Installation expert.

To achieve a top performing Green Roof System, we create an extension of the existing roof system using waterproofing and drainage systems, filter cloth, lightweight growing mediums and hearty vegetation.

There are public and private benefits to installing a commercial green roof system on your building; we have briefly outlined these benefits below:

Green Roof System Private Economic Benefits

The life span of a roof system will be extended exponentially as the commercial green roof system offers protection from damaging elements such as ultra violet rays and variances in temperature.

Using a commercial green roof system may reduce the amount of necessary building insulation and the potential to incorporate cooling and/or storm water treatment functions. A green roof system may also allow you to reduce or eliminate roof drains.
Commercial green roof systems have proven to decrease community resistance to new commercial developments and add usable space to a commercial building portfolio.
Depending on the extent of the commercial green roof system design, there is potential for an organization to realize regional and/or national market exposure. The aesthetic appeal of commercial green roof systems increases the value of the property and the marketability of the building as a whole, particularly for easily accessible commercial green roofs.

Having the potential improve employee productivity, commercial green roofs will also satisfy the aesthetic needs of those looking down from adjacent buildings.

Interior Comfort

A green roof system with a 12cm substrate layer can reduce sounds of machinery, traffic, or airplanes by up to 40 decibels.

Commercial Food Production

The Fairmont Waterfront Hotel (as mentioned in The News section) in Vancouver used to grow herbs, flowers, and vegetables on its accessible roof, saving its kitchen an estimated $30,000 a year in food purchasing and processing costs.

  • Decreased need for health care services from reductions in ground level ozone resulting from a reduction in the urban heat island.
  • Increased worker productivity and creativity
  • Decreased need for health care services and medication due to the benefits of passive experiences with nature and vegetation
  • Extending the lifespan of landfill sites by reducing re-roofing material waste

Improved Air Quality

Filtration of Airborne Particles:

  • A green roof system will not only absorb heat, decreasing the tendency towards thermal air movement, but will also filter the air moving across it.
  • 1 m² (10.76 ft²) of grass roof has the potential to remove between 0.2 kg of airborne particulates from the air every year.
