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.

Modified bitumen on a compact Dallas apartment building
A medium-grey cap sheet behind brick parapets, draining to an internal outlet.

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: cap-sheet laps running to a parapet, with the base flashing turned up behind the coping.
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
Parapets on all sides mean there is no free edge for water to leave from. The internal drain is the only exit, and it is treated as the critical element it is.
02
On an occupied residential building the difference between a leak and a report of a leak matters. A stain on a top-floor ceiling can start several metres from where it appears.
03
Cap sheet is repairable in a way some membranes are not, so a targeted repair is often the honest recommendation rather than a replacement.

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.
