Philadelphia’s freeze/thaw cycle can turn a small issue into a serious leak—especially on older rowhomes with flat or low-slope roofing. At Philly Roofing LLC, we prioritize roof repair, roof leak diagnostics, and long-term solutions across Center City, Kensington, South Philly, and Strawberry Mansion.

Common leak sources in late winter

Cracked flashing around chimneys, parapet walls, and roof penetrations
Clogged scuppers/drains that trap water and push moisture under seams
Split membrane seams from temperature stress
Damaged masonry on parapet walls that lets water enter and travel

What to do immediately

• Look for water stains near exterior walls and top-floor ceilings
• Check for bubbling paint or soft drywall (a sign of ongoing moisture)
• Clear visible debris from drains if safe to do so
• Schedule an inspection before the next heavy rain

For storm preparedness and safe recovery steps, FEMA has straightforward guidance that homeowners can follow.
