If you’ve got ceiling stains, bubbling paint, or a drip that “only happens during heavy wind,” winter is the season to take it seriously. Philadelphia roofs—especially flat and low-slope systems—get punished by freeze/thaw cycles, wind-driven rain, and clogged drainage paths.

At Philly Roofing LLC, we focus on repairs that solve the source, not the symptom.

Winter leak clues you shouldn’t ignore

• stains that grow after storms
• bubbling at ceiling corners near exterior walls
• damp smells after rain
• new cracks at roof-wall transitions
• water showing up “far” from the suspected spot

Flat roof leaks can travel, so diagnosis matters.

The most common Philly flat roof failure points

• flashing at parapet walls and transitions
• pipe penetrations (boots and collars)
• skylight edges
• scuppers and drains with poor slope or blockage
• edge metal and termination bars
• old patches that separated over time

Repairs that hold up in winter

We typically prioritize:

• proper flashing corrections
• membrane patching done with compatible materials
• drainage improvements (scupper/drain corrections)
• edge detailing that stops wind-driven water
• targeted maintenance to prevent repeat leaks

When a repair becomes a replacement conversation

If the roof is at end-of-life, we review:

• slope and drainage strategy
• insulation approach
• long-term material options
• parapet and edge conditions
• realistic maintenance plan
