A roof is not just shingles. It is a water-shedding system made of layers that work together — and most roof problems are one layer failing. Understand the system and every inspection, claim, and quote finally makes sense.

Lesson 1: How a roof actually works - narrated.

Read the transcript
Most people think a roof is just shingles. It is actually a water-shedding system: the deck, the underlayment, the flashing, and the shingles. Each layer has one job, and most roof problems are one layer failing. Understand the system, and every inspection and every quote finally makes sense. That is Lesson One of Inspector Roofing University.

Everything is nailed to the deck: the plywood or OSB sheeting over your rafters. When you see “roof replacement,” this is the surface that carries the shingles — and it is the first thing an inspector checks for soft spots.

Underlayment

The water-resistant layer under the shingles — the second line of defense. Codes require a synthetic or felt layer, and missing or torn underlayment is a real finding, not a nitpick.

Flashing

The metal pieces at every joint — valleys, chimneys, skylights, and walls. Flashing is where most leaks begin, because water moves sideways and uphill at these joints, not just down.

The shingles

The visible top layer. Shingles shed water over the slope and into the gutter. They also seal against wind; granule loss exposes the asphalt to UV and shortens life.

FAQ For This Roofing Topic

What should a homeowner do first?

Start with a documented roof inspection, clear photos, attic or ceiling evidence when relevant, and a written explanation of what was observed. The goal is to separate urgent leaks, repairable details, maintenance items, storm indicators, and replacement-level conditions before money is spent.

When should a roof issue be treated as urgent?

Active leaks, interior staining, missing shingles, exposed decking, loose flashing, tree impact, unsafe access, or repeated water entry should be reviewed quickly. A temporary dry-in may be needed before a full repair or replacement decision is made.

How does Inspector Roofing support insurance-aware documentation?

The company documents observable roof conditions, photos, measurements, repairability, code and manufacturer context, and scope language. Coverage, payment, claim approval, and policy decisions belong to the insurance carrier, not the roofing contractor.
