Flat Roofs: Products & Benefits

Many flat roof product manufacturers certify Raindrop Roofing N.W.’s work with their highest confidence and full, manufacturer-carried warranties. We are certified installers for CertainTeed, Firestone, Genflex, and Weather Bond.

1. Membrane/Single Ply Roofing
   Membrane or single ply roofing makes roofing over feasible and installation is both simple and safe. It's an ideal option for many commercial buildings because it's lightweight, waterproof, and easy to maintain. Approximately 70% of commercial roofing installation jobs across the U.S. now use this type of roofing, according to the industry association. Advances in production have dramatically increased effectiveness against leaks since it's introduction in the 1970s.

Within this roofing type, we offer several options:

1. TPO (Thermoplastic olefin)

• Color options: White, grey, and black
• Excellent UV stabilizers
• Few seams in the roofing where water can leak in
• Energy Star rated for efficiency

We can offer Genflex or Weather Bond materials and labor warranties carried by the manufacturer. Genflex’s TPO roofing systems include 15 or 20-year warranties. Manufacturer carried warranties means that even if the roofing contractor is no longer in business that the manufacturer will cover any warranty repairs (both labor and materials).

2. PVC Roof

• Color choices: White or grey
• Expands and contracts easily with weather patterns
• Different PVC thicknesses offer property owners budget to long-lasting options
• Few seams in the roofing where water can leak in
• Energy Star rated for efficiency

Raindrop Roofing Northwest installs Johns Manville PVC and Duro-Last’s PVC roof products. Duro-Last has a 15-year labor and materials warranty and is one of the only manufacturers whose warranty covers leaks, damage to your building or contents, and ponding water.

3. Basic black rubber roofing (EPDM)

• Contains UV stabilizer
• Installed with adhesive solvents.
• Good shorter term option for commercial buildings

2. Torch Down Roofs

• Smooth torch down and granulated torch down products available
• Warranties range from 10 to 20 years with full system (labor and product) coverage
• Redundancy of layering ensures water protection
• Granulated torch down products are offered in many decorative colors.

Raindrop Roofing Northwest is one of the only roofers in the Portland metro area appropriately certified and authorized for Torch Down roofing.

Our company is a Silver Star-certified installer for CertainTeed. That means that CertainTeed has enough confidence in our work that they offer a no-dollar limit warranty on our flat roof installations.

Green Roofs: Products, Benefits, & Services

1. Reflective shingles

• Contains UV reflective granules that prevent attics from heating up
• 30 year, 40 year, 50 year, and lifetime warranties depending on shingle
• LEED certified options
• Recycled materials used in some products
• Landmark Solaris and Malarkey's Eco Oasis are the two most common types

2. Solar Panel Preparation & Roof Maintenance
   Our competent team installs brackets and feet for solar panels – preparing your roof for solar panel installation. We can also maintain roofs with solar panels.

3. Eco Roofs (i.e. rooftop gardening)
   Raindrop Roofing Northwest lays down a Torch Down, PVC, or TPO membrane to prepare roofs for gardens. We partner with EcoRoofs Everywhere to help property owners prepare and plan for rooftop gardening.
4. Photovoltaic shingles
   Coming in late 2010, these shingles look exactly like typical composition shingles but they pack a special punch. We carefully drill small holes through your sheeting to run the tiny wires from these special shingles into your attic. The wires then plug into a battery pack that can then generate energy for your home.
