Reroofing a relatives house. Found 6 layers of shingles and roll roofing
-- over 1.5 inches thick. Whew! Major tear-off job. So far have about 5
hours on the tear off and only half way thru.
I've been wondering if anyone has ever seen or built a "tear-off" machine.
I can envision something compact like a garden tiller in size:
1. a walk behind handle
2. a powered rubber rear tread like a snowmobile (but very, very slow like
a granny gear)
3. a flat, thin head that vibrates side to side and front to back (with
movement like a sickle-bar mower).
Good idea, but I already got the patent. Did it about ten minutes ago
right after reading your post.. :-)
actually, if they can prove they thought of it first, and had taken steps to
progress the invention, i believe you would find yourself in a losing legal
as i understand it, one of the best ways to protect your invention is to
make it public. gives you the documentation you need.
" "Our tear-off machine with the roof remover has helped us the most,"
says Doug Griffith of Griffith Roofing, Beaverton, Oregon. "It's a real
labor and back saving piece of equipment." As an added benefit, there
are several attachments that can be purchased separately and used in
conjunction with the tear-off machine making it a multi-functional piece
of equipment. The power broom attachment offers right and left angle
positions for windrowing gravel and the tooth blade attachment is used
to remove nails from base sheet or shingles. There is even a
felt-slitting blade. Though, it is the roof remover attachment that is
the most common and is said to remove up to 30 squares of built-up
roofing and insulation per hour. "On the demolition portion of a job,
it cuts our labor costs in half and saves about 25% on overall job
costs," concludes Griffith. "
I know this doesn't address your question about a powered device to remove
shingles..but I assume you have tried the device that looks like a flat
shovel with teeth on the front that is designed for removing roof shingles.
A friend told me that it really helped in his roof removal. I've never used
one myself but noticed it in the hardware dep't at Sears and suggested it to
my friend. He was in his 70's and a former farmer and had never heard of it
When we tore off the roof on my grandmother's house 20-some years ago, my
brother made a couple stripping tools by welding pipe nipples to sharpened
pieces of old car leaf springs. Looked crude as hell, but worked rather
well. Slide under an edge, rock it back, and the shingle popped right off in
most cases, nails and all. Never seen a commercial tool with the same
configuration, but I haven't looked real hard.
I use to do roofing. I used first a flat bottom shovel. It will remove
old nails as well. If old roof is stapled use a pitch fork. Have fun.
If you rent an air compressor and nail gun you can roof it all in a day.

There are such animals for flat roofs. I once worked with someone using
one, I was not impressed. It cut the fasteners, but left the shank sticking
out. We had to go back and knock all the sharp shanks down.
I did roofing for about 20 some years. We used tools by AJC, nice tools and
they are made locally here in Ohio. Al Crookston started the company, he was
a fellow roofer I knew b/4 he became rich. Now a very large manufacturer
for roofing tools. You should be able to pick up a _Shing-Go_ Shovel_ at
your local lumber supplier or roofing supply. The 47" with fiberglass
handle runs about $50. The rip blades are replaceable and run about $11,
but they would last the occasional roofer a life-time. We replaced the rip
blades b/4 every season, the rip blade catches the fastener head and you
just push down on the shovel. Also, they don't come with a protective skid
plate, _buy_ one because it will save the shovel from breaking because the
heal of the shovel sees a lot of use. Skid plate just bolts on and only
costs about $6, well worth the money. Here's a link.
Union Tools also makes shingle rippers. I used these b/4, but like the AJC
better. You should be able to find these at your local stores also.
