What Is a Green Roof?
A green roof consists of a waterproof membrane topped with layers of soil and vegetation. There are two main types:
- Extensive: Lightweight, shallow soil (2–6 inches), low-maintenance plants like sedum.
- Intensive: Deeper soil (>6 inches), supports a wider variety of plants, even small trees, but requires more maintenance.
Benefits:
- Insulation: reduces heating/cooling costs
- Stormwater management: absorbs rain, reduces runoff
- Air quality: filters pollutants
- Aesthetic value: urban greenery
Solar Roofing Options
Photovoltaic (PV) Panels: Traditional solar panels mounted on racks above roof.
Building-Integrated Photovoltaics (BIPV): Solar shingles or tiles that function as both roofing material and energy generator.
Benefits:
- Electricity cost savings
- Potential tax credits and rebates in Colorado
- Increased property value
