The Safety Stuff
Roofing is an inherently hazardous operation. Never stop paying
attention, and be aware the hazards particular to these tear off tools.
Heavy work gloves with
knuckle protection are highly recomended. Every imaginable item of safety
gear and procedure must officially be required.
 |
Fall Hazard 1:
Razor Bar is not rated for personal support. It is not to be used as a
climbing aid, except to prevent an otherwise unavoidable fall. Always
use accepted safe staging practices and fall protection equipment when
required.
Fall Hazard 2:
Razor Bar will hit an occasional nail and come to an unexpected stop.
When bearing down hard on the tool, it is possible to push oneself off
the roof, or topple the staging, particularly ladders and ladder
systems. Always be expecting this unexpected stop.
Electrocution/Fire/Explosion Hazard:
Exercise extreme caution when working around the power supply cables from the house to the pole.
Razor Bar conducts electricity, and can easily pierce the insulation on
these cables.
Impalement Hazard: Never point Razor Bar at anything you do not intend to destroy
.

Operation
| Razor Bar puts the roof shingles on the
ground and produces exposed nails. One Razor Bar can clear for roughly
three nail pullers and/or feed for roughly two debris haulers. |
 |
 |
An
upward stroke angle permits gliding, a condition where the sharp
cutting tips do not contact any surfaces. When Gliding, Razor Bar rides
over and around obstacles, slides on ice belt, and minimizes damage to tar
paper. |
A
sideward stroke angle helps direct the roof debris clear of the nails and
send it the desired direction. Particularly helpful with brittle
roof shingles which tend to launch when freed.
Top-down
vertical passes take advantage of both gravity and the undisturbed
roof’s shedding ability. They also leave room for others to work.
The
roof debris doesn’t slide well on the exposed nails. Therefore it is
important to continuously roll it on top of the undisturbed shingles,
particularly in shallow-pitched or brittle tear off conditions. On steep-pitched
roofs, pull nails before moving up to the next staging tier.

In order to break off
a chunk of debris it helps if it is not attached to the roof shingles above,
most notably in shakes. On a shallow-walker roof this is a non-issue after
blowing the cap apart (0.3 MB) On a steep/staged it is good to first reach up and
“crack” the roof before going after the big bites. Cracking (0.5 MB)
To get the full speed advantage, always seek to produce quality exposed
nails. On the easy roof jobs, nail removal should look something like this (0.5 MB) With headbreakers and bentovers, it will go more like this (0.5 MB)

Roof conditions
Flashings
need be approached with caution, especially lead. Use short, careful
strokes to loosen, then use the hooks to rip away the major pieces of shingle. Fine-clean with the roof shovel.
Staples,
another caution. Glide high and feel your way over them. Avoid
producing “one leggers” which don’t pull well.
 Tar paper,
ride over it to produce the best quality exposed nails and less
airborne debris. Avoid shredding it, which makes a mess and conceals
the nails.
Roll systems suck. Glide off what comes easy, then it's nibble time with the shingle shovel. Air Ripper is nice on these roofs.
Steep/staged pitches are the easiest roof shingle removal jobs. Pull nails before bumping up and Razor Bar is unbeatable.
Easy-walker roofs require greater adherence to the operating strategies. Avoid having lots of roof debris spread out on the exposed nails
Hard-walker
pitches, those between 6 and 10, are the trickiest roofs because of leverage.
Some sort of staging need be involved for Razor Bar to work here such
as ladder system, cleat, valley, or rope.
