Barry, first, there's lots of good strong imagery here--and potential for lots more. The sounds of the tools and of the falling ice, the voices--joyful or cursing--of the workers, shouts of onlookers, etc., the glare of sunlight on the ice and snow. A narrative image of the way the workers/partiers attack an ice dam: I assume you don't want it all to come down at once, so you work up from the edges? The more specific the action and sounds, the stronger the impression on the listeners.

Another comment--when you said the tune was like "The Times They Are A-changin'," I kind of expected the fourth line of each verse to be a foot* shorter than the other three (another of your songs reads like it uses much the same tune), and if you could shorten these lines, the verses would have a more emphatic feeling.

*(a poetic foot is usually two or three syllables, either the first or the last one accented: you are using a lot of anapests (da-da-DAH) as did Dylan in "The Times..."--a great pattern for narrative verse, particularly if alternated with iambic feet,)

A few line by line notes: I've suggested a few words to make the rhythms more regular--probably overdone on my part, as an occasional break in rhythm can be emphatic--but emphasis has to be controlled to have emphatic effect]

Ice Damming by Barry Finn

It's winter in New England and throughout the land ["cold" for "winter"?]
The trucks start rolling with all available hands ["ready" for "available"?]
It's a party, a tradition, a picnic, a plan [can you replace "tradition" with a two syllable synonym?]
Over mountains of snow they attack the Ice Dams [something shorter like "There're ice dams out there that need breaking."]

chorus;
And you hear everywhere the cry Ice Dam
It's a flue, it's a fever that spreads through the land ["flu" not "flue" if paralleled with "fever"]
Man your pickups, your axes, every woman and man ["each" for "every"]
And answer the call "Get the Ice Dam!"

Blaze a path round a house in snow that's waist deep
Take a snow rake or shovel and clear up 3 feet
Crawl the edge of the dam on a roof that's to steep ["too" for "to"]
And start pounding on ice and give nobody peace

chorus:
While on a 40 foot ladder that slides on the ice
Out comes the homeowner who tries to be nice
I like what you're doing but I don't like you're price ["your," not "you're"]
For a few dollars less would you still risk your life?

chorus:
Some shingles may break and the ice will sure fall
If we land on your shrubs sure you'll give us a call
And the checks will bounce as we bounce off your wall
s It must be illegal to have such a ball ["So much fun you know is illegal!"]

chorus:
Like ants, like locus[ts] we're all over your roof
We cry Ice Dam and drink 100 proof
A windfall in winter is scarce that's the truth
When ice damming is done we're a winter recluse ["when ice damming's done we are hermits"]


I don't want to get too carried away--it's your song. One more thing I would suggest is the verse to answer the homeowner's request for a lower price could be a description or narrative of an actual injury or death producing accident which occurred during an attack on a dam (the dams must also be dangerous during a thaw, no?)

I have probably given you far too much here, so disregard anything you like--all of it if you like: it's your singing that makes it, anyway.
