Roof SteamIce Removal
Sheets & Glaze, Gone

Ice runs several pounds per square foot per inch of thickness — a thick sheet across a large roof is tons, which is why long-span and older structures earn priority attention.

Sound structure, thin ice, no leaks: often yes. The assessment exists because “often” is not “always,” and the exceptions are expensive.

Yes — snow shovels and rakes off; bonded ice only steams off safely. Storms often demand both in sequence.

Several pounds per square foot per inch of thickness — a thick sheet across a whole roof is measured in tons, which is why long spans earn priority.

Thin bonded glaze on sound structure often rides winter out; thick spans, sagging signals, or ice feeding an active leak demand action. Honest assessment decides.

Freezing rain glazes entire fields in one event, and thaw-refreeze cycles build valley glaciers — different formation than eave dams, same steam solution.

Yes — weight stresses long spans, expansion works at every fastener and seam, and sliding sheets tear vents and gutters on the way down.

Different ones — less damming, more sheet-slide hazard, which is why metal’s ice conversation is snow retention rather than removal.
