Solar Panel Installation in North Jersey

Solar panels last 25 years or more, so the roof under them has to as well. Terra Nova is a roofing company first: we check and fix the roof before solar goes on, and we seal every mount so the panels don't cause leaks.

Should I replace my roof before installing solar panels?

Yes, if your roof has less than about 10 to 15 years of life left, replace it before installing solar panels, because panels usually stay up 25 years or more and removing and reinstalling them later for a new roof adds cost. If the roof is newer and in good shape, solar can go on now. Terra Nova inspects the roof first and tells you which.

Solar on North Jersey roofs

Snow load, wind and ice dams all matter when panels go on a roof here. Mounts should be flashed like any roof penetration, panels shouldn't trap snow over gutters where ice dams form, and wiring should run cleanly without new holes in the roof. These are roofing details first, which is why we treat solar as a roofing job.

Questions homeowners ask

Can solar panels cause roof leaks?

They can if mounts aren't flashed and sealed correctly. That's why we treat every mount as a roofing detail.

Can you install solar on an old roof?

We check first. If the roof is near the end of its life, replacing it before solar usually saves money.

Do you offer battery backup?

Yes, battery backup can be added to a solar system.

Can you take panels off for roof work?

Yes, we remove and reinstall panels when the roof needs work.

Is financing available?

Ask about financing options when you request your estimate.

Do you fix leaks around existing solar panels?

Yes. Leak repair →

Can solar panels go on a flat roof?

Yes, with the right racking and a roof membrane in good condition.

Do panels damage shingles?

Not when they're installed and flashed correctly.

What happens to snow on solar panels?

It usually slides off faster than off shingles. Snow guards may be needed above walkways.

Can you inspect my roof before another company installs solar?

Yes.
