What do people thing about the risk of putting PV on an asphalt shingle roof in New England? What is the likelihood of leaking and how can it be minimized? I have a 1 year old roof with a 20 year warranty on labor and 30 years on materials and don't want to damage it. Thanks.

When installed the PV will not inhibit a roof warrantee. Because panels are raised off the roof it allows for. Air movement under the modules. Each part of the system installed should be installed into rafters not roof sheathing. The lags should be pre drilled and filled with Solar Seal. Penetrations in the roof should not leak if installed properly. All lags should be stainless steel to keep from rusting.

You can most certainly put solar in New England. I don't recommend simply lag bolting an anchor into the roof with sealant. This WILL eventually leak. We just removed an entire system from another installer here in NJ - the entire roof was leaking from dozens of places. 7 years old. You need to use a product like the Quick Mount PV - a flashed anchoring system. If you use this type of anchor and it is installed correctly it will last longer than your house will. The system should be installed off the roof to allow air to circulate under the panels. The solar system will actually extend the life of the roof under it as it protects it from the sun, the rain, the snow, etc.
