The five passes
A roof assessed from one angle is a roof assessed once. These are the passes every Jacob assessment makes, in this order, so that coverage does not depend on how the day is going.

The pass that shows how the roof sits on the building — planes, hips, valleys, and how it meets everything around it.

Straight down. This is the view that makes drainage legible and stops a plane being missed because it was awkward to reach.

What the property actually looks like to a person standing in front of it — the only view most quotes are based on.

Close enough to read the assembly: courses, seams, terminations, penetrations. Findings are photographed at this range with something for scale.
On this roof: terracotta tiles running across a low hip, the weathering uneven between courses.

Mid-installation, where the parts that end up hidden are still visible. A roof is easiest to judge before it is finished.
What this roof raises
Every property puts its own questions in front of an assessor. These are the ones this system on this kind of house raises — and the same ones we would bring to yours.
Low-pitch tile depends more heavily on the underlayment than steeper tile does, because water moves off it more slowly. The pitch is measured rather than estimated.
Pool chemistry and the damp microclimate around a pool accelerate weathering on nearby roof and metalwork. It is a real effect and it is noted where it applies.
Colour-matching replacement tile on a weathered roof is rarely exact. Saying so before the work is better than explaining it afterwards.

Four steps, three things to type. We confirm the address is in our area, then come and look at the whole roof — not just the bit you pointed at.
