A modest red-brick bungalow on a narrow lot with a detached rear garage — two separate roofs, and both get assessed.

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: a shingle field meeting the fascia and drip edge above the gutter line.

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.
A detached garage is a second roof with its own age, its own condition and often its own history. It is assessed and photographed as a separate structure rather than folded into the house.
Narrow lots restrict access for tear-off and disposal. That is a practical constraint that belongs in the scope rather than turning up as a surprise on the day.
Older bungalow roofs frequently have limited ventilation by modern standards. Adding ventilation during a replacement is usually cheap; adding it afterwards rarely is.

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.
