Vegetative System Options

After a detailed roof assessment and structural evaluation, there are a number of options to choose from.

Sedum

This extensive system is lightweight, requires minimum maintenance, and offers an ecological protection layer instead of gravel covering.

Wildflower

Wildflowers are a semi-intensive system featuring a high drainage capacity and the aesthetic choice and flexibility of an array of flower varieties.

Paver/Hardscape

This system has the hybrid benefits of green roof pavers and stormwater management in a single system. Sedum carpet, rockery-type plants, or heather with lavender can be applied. Stormwater builds to a predetermined depth and drains at a set maximum rate.

Temperature Regulation

Green roof systems help to keep buildings cool in the summer and warm in the winter, reducing energy costs.

Improved Air Quality

Vegetation absorbs pollutants and releases oxygen, improving the quality of air. 

When it rains in the green forest, rainwater touches the forest components, like the tree canopy, branches, and vegetation. The canopy shields the forest floor, lessening the impact of falling raindro

Stormwater Retention

Green and Blue systems absorb water, alleviating the pressure on local rainwater drainage systems.

Waterproofing Protection

Green roofs protect the waterproofing system from harmful UV rays and temperature fluctuations which can reduce the lifespan of the roof.

Provide Natural Habitats

Reduce the impact of development by encouraging wildlife and nature to thrive in urban envireonments.

Stimulating Aesthetics

Green roofs create a visually appealing environment for building occupants and the neighbouring buildings. 

NYU F.U.N. Roof Project Highlight

Garland has been supporting the New York University hospital system for over a decade with a variety of roofing applications. One of the buildings where we hadn’t yet re-roofed was aging and beginning to experience leaks. At the same time, the roof provided an opportunity for a vegetative system, as patients from surrounding hospital buildings would have a much-enhanced view looking down on a lush green roof versus the previous traditional system.  Garland rep Keith DeVito worked on developing a system that would deliver a watertight environment - and the sustainable and aesthetic benefits of a green roof.
