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.

Torch-down membrane on a small Dallas commercial building
A cream-parapet urban building with three rooftop curbs — a low-slope roof where everything depends on where the water is meant to go.

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 membrane lap running to a parapet base flashing, with a mechanical curb behind it.
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
On a low-slope roof the covering is only half the system. Where the water leaves — drains, scuppers, overflow — decides whether it works, and those are checked and photographed separately.
02
Torch-down is installed with an open flame. That imposes real constraints near parapets, equipment and anything combustible, and it is a legitimate reason to specify a different system on some buildings.
03
Ponding after rain is normal on a low-slope roof for a short period and a problem if it persists. The distinction is a timed observation, not a judgement made from a single photograph.
Book an assessment
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.
