Roofing

The clearer and calmer the night was, the wetter your roof is likely to look at dawn, since that’s exactly when this cooling effect works best.

This is one of the most universal, harmless optical effects on any roof, and the test for whether it’s something else is simply waiting for it to dry.

There are two totally different kinds of shine here, and the test that tells them apart is simply whether it’s still there once the roof dries out.

Working through the ordinary explanations first, in order, usually resolves the mystery before you need to worry about anything structural at all.

Color is a red herring here; the actual test that matters is whether your shingles have gone bald and shiny anywhere, regardless of what color the grit is.

The four-question test that actually distinguishes a completely normal roof from one that’s aging faster than it should: light and even, or heavy and sudden?

Identifying the material, not just noticing that something fell, is what actually tells you whether this is routine or worth a call.

The distinction that matters: sandy grit in the yard is normal wear, but an actual piece of shingle material means something physically came off the roof.

If nails are landing on the driveway, they most likely traveled through the gutter system first, which explains why they show up near downspouts specifically.

The nails you’re finding are very likely years old, left behind during a roofing job that happened long before you noticed anything in the gutter.
