Pass 01 of 5
Aerial, oblique
The pass that shows how the roof sits on the building — planes, hips, valleys, and how it meets everything around it.

Low-slope membrane on an Irving mixed-use building
A stepped-parapet brick building with a roof drain and a service lane — a working commercial roof rather than a showpiece.

The five passes
The same five views, every time.
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.
Pass 02 of 5
Aerial, plan
Straight down. This is the view that makes drainage legible and stops a plane being missed because it was awkward to reach.
Pass 03 of 5
From the street
What the property actually looks like to a person standing in front of it — the only view most quotes are based on.
Pass 04 of 5
System detail
Close enough to read the assembly: courses, seams, terminations, penetrations. Findings are photographed at this range with something for scale.
On this roof: a roof drain set into the membrane field, with the surrounding sump and the clamping ring visible.
Pass 05 of 5
Work in progress
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
Three things a roof like this makes you check.
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.
01
A stepped parapet means the roof is really several roofs at different heights. Water that leaves one and lands on another concentrates in a way a single-level roof never does.
02
Internal drains are the whole system on a building like this. A blocked drain does not leak slowly — it loads the deck, and that is a structural question, not a covering one.
03
Commercial re-roofing usually has to be staged around a tenant who is still trading. That sequencing belongs in the scope from the beginning, because it changes both the programme and the price.

Tell us where, and what you noticed.
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.
