You spot the shingle in your yard after a windy night — textured side up, a corner cracked, granules scattered across the mulch. You make a mental note to call someone. Then life happens, and two months later that bare spot on your roof is still just sitting there. How bad can one missing shingle really be?

The glass overhead is clear, and that is not what the crew on your roof is looking at.

The wind quit around two in the morning, and by breakfast the yard had mostly sorted itself out.

You noticed the sapling growing out of your gutter last fall and told yourself that's a problem for spring. By the time you got around to it, the whole trough was packed solid — a compressed mat of wet leaves, shingle granules, and dirt sitting through four months of freezing and thawing. The downspout was completely blocked. And the fascia board behind it felt soft when you pressed your thumb against it.

A shingle roof is a system of small, overlapping pieces held down by two things: nails and a strip of factory-applied adhesive.

A roof is not a sealed lid. A working attic breathes, pulling cool outdoor air in at the bottom edge and pushing warm, damp air out at the top, all day, every day.

You're up a ladder cleaning gutters in September when you press your hand against the trim board at the roof's edge to steady yourself—and your palm sinks in a little. Not wood anymore. Something softer. The paint looks fine from the driveway, but up close it's blistered, and the board behind it has turned gray and spongy. That's fascia rot, and it usually means water has been working on it for at least two seasons before it got obvious.

Gutters do their job quietly for years, then one spring you notice a section sagging over the walkway or a stain creeping down the fascia board that wasn't there last fall.

You hear it before you see it: a low, tight creak from somewhere above the ceiling, right after a heavy snowfall settles in overnight.

These windows are a perfect way to invite nature into your space without compromising style or functionality.

Ask five people how long a window is supposed to last, and you'll get five different numbers, and none of them will be exactly wrong.

You're standing at the kitchen window with your coffee, and the yard has turned into a smear of gray and white.

You're cleaning out your gutters in October, and the downspout is clogged with what looks like coarse sand—gray-black grit that pours out into your palm like the inside of an ashtray. That's not dirt. Those are the granules from your asphalt shingles, and a gutterful of them means something is going wrong with your roof.

Water spilling over the front edge of a gutter looks like a small nuisance until you trace where it lands.

Look up at the edge of almost any pitched roof, and you will notice the roof does not stop flush with the wall.

It's January, 7 a.m., and you are standing in the entryway in your socks. The coffee's hot. Your feet aren't. There is a band of cold air moving past your ankles that has nothing to do with the floor — you hold your hand near the steel door face and feel the chill radiating off it like the side of a chest freezer. The door looks solid. The weatherstripping is intact. But the door itself is bleeding heat, and it's been doing it every morning for years.

The morning after the storm, the sun is out, and the street looks fine. Your neighbor's patio furniture is upright. Nothing obviously wrong. So you head back inside, skip the yard walk-through, and go to work.

The single biggest predictor of how long your roof will last is the material sitting on top of your home.

Two houses on the same block can wear completely different skins, and both be right.

The hail stopped around 3 p.m. You walked outside, and the driveway looked like someone had dumped a bag of marbles across it. The downspout was bent sideways. Up on the roof, three shingles were sitting in the front yard. By the time you got inside, the ceiling in the back bedroom was dripping. You had maybe 30 minutes of daylight left and no idea what to do first.
