We understand that investing in a green roof is a significant decision.

You'll appreciate our attention to detail and commitment to sustainability. Our green roofing systems are designed to thrive in New England conditions, giving you a beautiful, environmentally-friendly roof that stands the test of time.
Types of Green Roofs
Extensive Green Roofs
These lightweight systems require minimal maintenance and are ideal for residential properties. We recommend extensive systems for homeowners looking for environmental benefits without the need for regular garden care.
Semi-intensive Green Roofs
This type offers a middle ground with moderate soil depth and plant variety. They balance the low maintenance of extensive systems with the greater biodiversity of intensive ones.
Intensive Green Roofs
These roof gardens create more substantial green spaces but require stronger structural support and regular maintenance. They're perfect for commercial buildings or homes where rooftop gardens are desired.
Green Roof Installation Process
Our team at Providence Roofing Company follows a systematic approach to ensure your green roof is durable, waterproof, and properly supports vegetation growth.
1. Removing Existing Roofing Materials
Before we can install your green roof, we must carefully remove any existing roofing materials. Our crew starts by thoroughly inspecting your current roof structure to determine what needs to be removed. We take extra precautions to protect your property during this phase.
2. Installing Roof Insulation and Underlayment
Proper insulation and underlayment are critical components of your green roof system. We install high-quality insulation boards that provide thermal protection and energy efficiency for your building.
3. Ensuring Proper Drainage System
A functional drainage system is essential for any green roof installation. We design and install drainage solutions that prevent water pooling while retaining enough moisture for plant health.
4. Applying the Roofing Membrane
The roofing membrane is your green roof's most critical waterproofing component. We install high-performance membranes specifically designed for green roof applications.
5. Weatherproofing and Aesthetic Considerations
Our weatherproofing process creates a reliable barrier against New England's varied climate conditions. We utilize high-quality waterproof membranes with root-resistant properties to protect your building structure. Additional weatherproofing features include:
6. Roof Maintenance and Upkeep
Your green roof requires regular attention to thrive. We offer comprehensive maintenance programs to ensure your investment continues performing optimally. Our maintenance services include:
Types of Roofing Systems
Single-Ply Roofing Options
We install three primary types of single-ply roofing membranes, each with unique benefits. EPDM (Ethylene Propylene Diene Monomer) is a synthetic rubber material known for its exceptional durability and weather resistance. This black membrane can last over 25 years and performs well in extreme temperatures.
All our single-ply options can be installed in warm roof configurations (insulation below membrane) or inverted roof designs for specific building needs.
Modified Bitumen and Built-Up Roofing
For buildings requiring multi-layered protection, we offer Modified Bitumen systems. These reinforced asphalt membranes contain polymers for enhanced flexibility and strength. They perform exceptionally well in cold climates and provide excellent waterproofing.
Our Built-Up Roofing (BUR) systems consist of alternating layers of bitumen and reinforcing fabrics. This creates a finished membrane that's 2-4 layers thick. BUR systems are known for their exceptional durability and can last 15-30 years with proper maintenance.
Both systems can be finished with reflective coatings to improve energy efficiency. They work particularly well on low-slope or flat commercial roofs where water pooling might occur.
Green Roof Components
A successful green roof installation depends on several essential layers working together to provide both functionality and beauty. At Providence Roofing Company, we ensure each component is properly installed for optimal performance and longevity.
Root Barrier Systems
Root barriers are critical protective elements that prevent plant roots from damaging your roof's structure. We install high density polyethylene (HDPE) or thermoplastic barriers that effectively block aggressive root systems while allowing water to pass through.
These barriers typically range from 30-100 mils in thickness, depending on the vegetation planned for your green roof. For intensive green roofs with larger plants and trees, we recommend thicker barriers for maximum protection.
Our root barriers are heat-welded at seams to create a continuous protective layer. This seamless installation prevents roots from finding weak points and penetrating the waterproofing layer beneath. The barriers we use are also resistant to microbial breakdown, ensuring long-term performance even in consistently moist conditions.
Waterproofing and Drainage Layers
The waterproofing membrane forms the foundation of your green roof system, protecting the building from moisture damage. We use high-quality EPDM, TPO, or modified bitumen membranes that can withstand constant moisture exposure.
Our drainage layers typically consist of:
- Dimpled plastic sheets that create water channels
- Geocomposite mats combining drainage and filtration
- Granular drainage layers for intensive green roofs
These components work together to maintain a 2-5% drainage slope, preventing water pooling that could damage plants or overload the roof structure. The drainage system also helps regulate water retention, providing plants with needed moisture while preventing excess water weight.
Soil Substrate and Vegetation
The growing medium for your green roof must balance weight considerations with plant needs. We custom-blend lightweight engineered soils containing:
- Expanded shale or clay
- Recycled brick or roof tile
- Organic compost (10-20%)
- Sand or pumice
This mixture ranges from 3-8 inches deep depending on your vegetation choices. For extensive green roofs, we recommend drought-resistant plants like sedums and succulents that thrive in shallow soil with minimal maintenance.
For intensive green roofs, we can incorporate a wider variety of plants including native grasses, perennials, and even small shrubs. The soil depth will be adjusted accordingly to support these more demanding plant types. All our plant selections are chosen for their ability to withstand roof conditions while providing optimal thermal performance benefits.
