The Basics
What is a Green/Living Roof?
A green or living roof incorporates a layer of vegetation grown on top of a waterproofing membrane, creating an eco-friendly roofing system that offers environmental and practical benefits. These roofs help manage stormwater runoff, improve insulation, reduce urban heat island effects and create additional green space, making them increasingly popular in sustainability-focused construction projects. Green roofs require a specialized layered system, including waterproofing, root barriers, drainage and growing medium, to properly support plant life while protecting the building structure beneath. In climates like Gresham, adequate drainage design is crucial to manage regular rainfall without causing water damage. While installation and structural requirements make green roofs more complex and costly than traditional options, the long-term environmental benefits, energy savings and aesthetic appeal continue driving adoption, particularly for commercial buildings, urban developments and homeowners prioritizing sustainability and unique outdoor living spaces.

Extensive & Intensive Systems
Choosing the Right Green Roof
Extensive green roofs use a thin growing layer and hardy, low-maintenance plants like sedums. They are lighter, less expensive, and suit most flat and low-slope roofs on homes, garages, and commercial buildings.
Intensive green roofs have deeper soil and can support grasses, shrubs, and even small trees, creating a usable rooftop garden. They are heavier and need more structural support and maintenance. We will help you decide which system suits your building.
Why Homeowners Choose It
Benefits of Green & Living Roofs
Stormwater Control
Plants and soil absorb rainfall and slow runoff into gutters and storm drains.
Better Insulation
The soil layer helps keep buildings warmer in winter and cooler in summer.
Longer Membrane Life
Plants shield the waterproofing from UV and temperature swings.
Cleaner Air
Vegetation filters pollutants and helps reduce urban heat.
Habitat for Wildlife
Provides space for bees, butterflies, and birds in built-up areas.
Usable Green Space
Intensive systems can create a rooftop garden or outdoor retreat.
Common Questions
Green & Living Roofs FAQs
Many flat and low-slope roofs can support a lightweight extensive green roof, but it depends on the structure. We assess your roof first, and a structural engineer may be needed for heavier intensive systems.
A properly installed green roof should not leak. The key is a high-quality waterproof membrane and root barrier installed beneath the plants, along with good drainage, which is where our roofing experience comes in.
Extensive sedum roofs need only occasional weeding, inspection, and some watering during dry summers. Intensive rooftop gardens need regular care similar to a ground-level garden.
Because the plants protect the membrane underneath from sun and temperature swings, a well-built green roof can last 40 years or more, often longer than a standard exposed flat roof.
