Homeowners across Providence County call about icicles. Icicles are cosmetic. The dam behind them, holding back standing water, is not. As part of our complete Johnston winter roof services, crews handle commercial ice dam removal across Providence County.
Wet Snow, Swinging Air: Johnston Ice Dams
The maritime air is the other half of it. Temperatures in Providence County move either side of freezing within the same day far more often than they do inland, and every crossing moves water down the roof and locks it at the eave.

Then there is the architecture. Johnston has a great deal of older housing with shallow eave returns, knee-wall attics and rooms built out over porches, all of which put heated air against cold deck with very little between.
Ice-barrier practice in Providence County
Historic district review in parts of Providence County adds a step on materials and sometimes on color, which is worth knowing before a re-roof is scheduled rather than after the permit is refused.
Commercial Ice Dam Removal in Johnston: How The Work Runs
The pitched sections nobody plans for
Very few commercial buildings are flat all the way across. Entrance canopies, mansard faces, dormers over older frontages and the sloped transitions between roof levels all shed onto places where people walk.
Those sections behave like a residential roof and get worked like one - steam at the eave, snow guards noted where they are missing, and the pavement below cordoned while material is coming down.
Multiple buildings on one site
Campuses, retail strips and multi-building properties get walked together and prioritized by which deck is closest to trouble, rather than worked in the order the calls came in.
One scope, one invoice, one contact. It is a meaningfully different job from nine separate ones.
What the board or the owner gets
A condition report with dated photographs, what was found, what was done and what is still a risk — in a form that can go to a board, an owner or a carrier without being rewritten.
For a managed Johnston property that document is usually the reason the spend gets approved without a second conversation.
Working around rooftop plant
HVAC curbs, exhaust fans, conduit, gas lines, solar racking and railing are all obstacles and all drift traps. The snow behind a large unit is usually the deepest on the roof and the ice under it the thickest.
Crews work around and under them rather than over, and anything running stays running.
Flat roofs fail differently
A pitched residential roof dams at the eave. A commercial deck dams at its drainage: frozen scuppers, iced-over internal drains, and ponding that refreezes into a sheet across the low spots. Water then sits on the membrane at depth, finds a seam or a flashing detail, and comes through into the tenant space below.
Parapet walls make it worse by holding the melt on the deck instead of letting it run off an edge. By the time it shows up as a ceiling tile stain in a Johnston unit, there is usually standing water up there.
