Daniel from Helmetta, NJ has been a Green Sun Energy Services client since September of 2021. The roof and the array were bought together, in one conversation, and went on five days apart the following January.
4,100 square feet of new roof
The old covering came off in a single layer on 6 January 2022 – stripped back to the deck rather than shingled over – and went back on as a GAF Timberline Lifetime system. There are 454 linear feet of rakes, eaves and valleys on this house, which is a great deal of edge for the size, and edges are where water finds its way in.
12 kW and 32 LG panels
The array followed on 11 January: thirty-two LG 375-watt panels, 12 kW in total, estimated at 16,429 kWh in the first year, on a Snap-N-Rack mounting system.
Why the roof went first
An array has a working life measured in decades and the roof underneath it does not. Putting solar on a covering near the end of its life means taking the array down and putting it back up again to replace the shingles – work that buys nothing. Doing the roof first, in the same week, means the panels will very likely never have to move. It is the single most useful thing to get right about a solar installation, and it is only available before the panels go on.

Questions from Helmetta homeowners
RoofingIs an ice barrier required on a roof in Helmetta?
New Jersey's adopted residential code carries ice-barrier requirements where the local climatic criteria show a history of ice forming along the eaves. Where the rule applies, the barrier generally has to run from the lowest roof edge to a set distance inside the exterior wall line. The permitted design and the local criteria decide it for a particular property.
SolarCan the old mounting hardware be reused after a reroof?
It depends on the manufacturer's requirements, the condition of the components and the warranty. The roof penetrations and weatherproofing components matter most, and a reroof is often the moment to replace the attachment and flashing rather than reinstall ageing roof-interface hardware.
SolarHow does an optimizer system differ from microinverters?
An optimizer system puts DC power optimizers at the modules and a single central inverter elsewhere; a microinverter system puts a small inverter at each module. Both can provide module-level monitoring and rapid shutdown when properly designed -- they are different architectures rather than one being the upgrade of the other.
