Roof Inspection for Solar Panels

Before solar panels go on your roof, it is worth having someone look at the roof itself, not the wiring, not the permit. KMK Roofing walks the shingles, the flashing, and the deck to make sure the roof can carry an array without a leak or a redo down the road. That is different from a general roof inspection, which looks at the whole roof for maintenance and insurance reasons. It is also different from what Massachusetts building code calls “solar-ready.” That term is a rule about a reserved zone required on certain new one- and two-family homes. It has nothing to do with checking a roof you already own. If someone uses that code term to describe a visit to your existing house, they are borrowing the wrong word for the job.

Repair, replace, or proceed

If your roof is worn out, replace it before the array goes on. Taking panels off later to reroof is slow and expensive, and it is not a job anyone wants to pay for twice. If your roof still has real life left, repair whatever needs it and proceed with the install. When an inspection turns up a borderline case, the safer call is usually to replace first. A wrong guess there costs you a full teardown, not a quick fix.

Orientation, pitch, shade, and what is already up there

The inspection also records what your roof offers for a solar layout, in plain words. Which way each roof plane faces, how steep it runs, and how much shade it gets during the day. It also notes what is already on the roof, like chimneys, vents, and dormers, since those all eat into the space panels can use. Shade matters more than most people expect. Even a small amount of shade on part of the array can cut its output for the whole day. This report gives you the layout facts. The production numbers and system design are your solar installer’s job.

What this report does not replace

This inspection does not replace a structural engineer, an electrician, or the permit. Solar panels add weight to the roof, and depending on your framing, they can add to the wind and snow load too. A licensed electrician has to handle the wiring, and your local building department has to sign off on the work. What KMK Roofing can tell you is whether the roof covering and deck underneath are sound and ready to carry the array. If roof repairs or a full replacement are needed first, we can walk you through that before you commit to a solar contract. Have questions about your roof before you call an installer?
