Install Options

The crew at SunWind has decades of experience in construction on Cape Cod, allowing us to tackle whatever possible install type would be preferential to the client. Below are some of the more common installation types that we perform, but if you are not sure if your roof or property is right for solar, don’t hesitate to contact us for a personalized consultation with no pressure nor obligation.

Roof-Mounted Systems

Asphalt Shingle

By far, the most common roof type we encounter is asphalt shingle (mostly architectural and sometimes three-tab variety). This is the easiest and most straightforward roof type to mount a roof-mounted system to, as it is very simple to penetrate through the roof into the existing frame (rafters or trusses) and flash to weather-tight. The warranty on these roofs range from around 25 to 40 years typically, and most PV systems are warrantied for around 25 years. Usually if a roof is less than 10 years old, it is safe to install solar on, but older than that it’s worth having a site survey and inspection by our crew to see if your roof needs replacing. Our team has decades of experience in construction on the Cape, and we can handle the re-roof (if called for) ourselves, concurrent with the solar install, without involving any subcontractors.

Shallow Pitch Roofs

Some other common roof types for shallower roofs (usually on commercial buildings) are EPDM rubber and rolled asphalt. Each of these has its own mounting style and materials, but they are typically similar to the types of flashings or boots that you would see around ventilation pipes or similar roof penetrations on such roofs.

Metal Roofs

Metal roofs are common in industrial and some commercial buildings. These roof types are usually pretty straightforward as well, as the solution is typically to clamp on to the standing seam without needing any real drilling or penetration into the roof and thereby avoiding the need to flash to repair the roof to weather-tight.

Penetration-Less Mounting

We also have clients that have stipulated that no penetrations be performed on their roof at all, and we are absolutely willing and able to accommodate this design criteria. Sometimes this means using a ballast system that is weighted down to withstand lift from high wind-speeds (read: nor’easter), or even tying into vertical framing members on opposite parapet walls so that the system spans the width of the roof without directly connecting to it. We have done many such individualized designs, and if you have a roof type that is far from typical and needs a custom solution, we are the ones to call.
