Every Plum winter produces the same two calls: the ones who see the ice early, and the ones who see the ceiling stain first. As part of our complete Plum winter roof services, crews handle commercial 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.
Commercial Roof Snow Removal in Plum: How The Work Runs
Reduction to a threshold, not a bare deck
The goal is bringing the load under the structure's capacity safely, with a cushion layer left on the membrane throughout. Ceiling Sagging or Bulging After Snow.
Scraping a commercial Plum roof to bare membrane costs more, takes longer and risks the roof covering for no structural benefit.
Drains and overflows come first
Before anything else comes off, the drains, scuppers and overflow outlets get opened. Otherwise the melt from the clearing has nowhere to go and the roof trades a snow problem for a ponding one.
On a deck in Plum with internal drains that means confirming flow below, not just clearing the grate.
Mid-span is where the margin runs out
Long-span steel and open-web joist roofs carry least where the drift is deepest. The average depth across the field is not the number that matters; the depth over the longest unsupported span is.
That is where crews measure on a Plum building, and it is why two roofs with the same snowfall can be in very different trouble.
Storm routes for a portfolio
Properties on a standing contract get cleared on a scheduled route after each qualifying snowfall, in a priority order agreed in advance by risk rather than by who calls first.
For anyone managing several Plum buildings that is the difference between a plan and a scramble.
Sequencing so the load comes off evenly
Stripping one bay to the deck while the next still carries two feet creates exactly the unbalanced condition that overloads a member. Structures object less to a lot of weight spread evenly than to a moderate weight concentrated on one side.
Crews work in passes across the whole span, reducing everywhere before going deeper anywhere, and the sequence is set before anybody starts rather than left to whoever gets up there first.

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 commercial snow pages: Penn Hills, Monroeville, Murrysville, Pittsburgh, West Mifflin, McCandless.
Scheduling for Plum tightens up during a freeze event, which is exactly when the phone beats the form. Water coming in means a call, not an email.
Most jobs do not stop at one service. Commercial Snow in Plum often runs alongside crane-assisted snow removal in Plum, and both get written into one scope rather than billed as separate visits.
