Solar on Asphalt Shingle Roofs - A Plain-English Guide
Last verified: September 2026
Asphalt shingle is the most common roof in America — and probably yours. Here's how a solar mount fastens to it, and what shingle age and condition change. Rather talk it through? My number is (330) 200-8042.
Solar on Asphalt Shingle Roofs, at a Glance
Most homes — in town or out in the country — wear asphalt shingle, which makes it the most standardized, well-understood roof for a solar mount. This guide explains how attachments fasten into the rafters, how flashing seals each one under the shingles above it, and why your shingles' age and condition shape the timing. There's a printable page-by-page version up top.
Common Questions
1 How does solar attach to an asphalt shingle roof?
Roof attachments fasten into the rafters underneath the shingles, and each one is sealed with flashing tucked under the up-slope shingles so water sheds over the hole, not into it.
2 Does my shingle roof's age matter?
Yes. Older, more brittle shingles are easier to damage during a careful install, and a roof nearing the end of its service life is usually better off re-roofed first. See our roof-age guide.
3 Can solar go on shingles in cold weather?
Shingles get more brittle in the cold, so an experienced crew plans around that. It's one more reason this is skilled, professional work rather than a weekend project.
4 Is asphalt shingle a good roof for solar?
It's the most common and most standardized case installers see, which generally makes it a straightforward, well-understood mount when the roof itself is in good condition.
5 What about the barn or outbuilding on my property?
Most barns and pole buildings are metal, not shingle, and mount differently. See our metal-roof guide and our guide on barns and outbuildings.
6 Will mounting on my shingles affect my roof warranty?
It can, depending on who does the work. Coordinating your roofer and your solar installer before the first hole is drilled helps protect it — see our roof-warranty guide.
