By the time a roof in Plum has a visible ridge of ice at the eave, meltwater has already been pooling behind it for several freeze-thaw cycles. As part of our complete Plum winter roof services, crews handle roof snow removal across Allegheny County.
Plum Ice Dams: Wet Snow and a Thermometer That Will Not Settle
Coastal snow is heavy with water, and a roof in Plum can take a foot of it in a night. That pack is a full reservoir from the moment it lands, not something that becomes one slowly.
Older Allegheny County housing stock makes it worse. Shallow eave returns, knee-wall attics and additions built over unheated space all put warm air against a cold roof deck with very little insulation in between.
Ice-barrier practice in Allegheny County
Ice-barrier membrane at the eaves is standard on re-roofs across coastal Pennsylvania, and many towns enforce it strictly. Homes that have not been re-roofed since that became normal practice are the ones that leak first.
Roof Snow Removal in Plum: How The Work Runs
Rain on top of snow
A warm rain onto a deep pack is the loading case that puts roofs on the news. The snow absorbs the rain instead of shedding it, the drains and gutters are still frozen, and the load can climb sharply within hours while the depth barely changes. Ceiling Sagging or Bulging After Snow.
When that forecast appears over Allegheny the priority order changes: large flat spans and anything already carrying a deep pack get cleared ahead of the line, before the rain rather than after it.
Snow load is a structural question too
Snow is not weightless. Wet pack and drifted snow can carry serious weight per square foot, and it collects unevenly — behind dormers, against parapets, in valleys and on the lee side of a ridge. Older framing and low-slope roofs are where that shows up first as deflection.
If a roof in Plum is already groaning, sagging between rafters or showing new cracks in interior drywall, that is a load problem and not a cosmetic one. Say so on the call and the crew treats it as urgent.
When to book it
After any heavy snowfall, and before a forecast thaw followed by a hard freeze — that sequence is what builds dams fastest. Properties with a history of dams at the same eave every year are worth putting on a standing clear-after-every-storm schedule rather than calling each time.
Why the second storm is the dangerous one
A roof usually carries the first storm without trouble. The problem is that the first pack settles, hardens and stops sliding, so the second storm lands on a base that is not going anywhere and the third has nowhere to go at all.
That is why clearing between storms is worth more than clearing after the whole sequence: each clear resets the base, and the roof never gets to the compounded load in the first place.
Skylights, vents and what gets flagged before clearing
Before a shovel moves, the crew walks the roof plan: skylights, solar panels, bath and ridge vents, satellite mounts, plumbing stacks and anything else that disappears under eighteen inches of snow. Each gets located and left proud of the surface.
On an older Plum roof the more useful part of that walk is often what it finds underneath - a lifted flashing or a soft spot in the deck that was there before the snow arrived and gets reported rather than covered back up.

Allegheny County Coverage From Plum
Crews working Plum cover the adjoining communities on the same route — Springdale, Verona, Oakmont, Harwick and New Kensington — so a storm week usually means one truck handling several addresses in Allegheny County rather than separate trips.
Nearest hub towns with their own roof snow removal pages: Penn Hills, Monroeville, Murrysville, Pittsburgh, West Mifflin, McCandless.
Crews cover Plum and the surrounding Allegheny County towns through the whole season, and during a freeze event they run from first light until dark.
Most jobs do not stop at one service. Roof Snow Removal in Plum often runs alongside ice dam removal in Plum, and both get written into one scope rather than billed as separate visits.
