Somerton PA Fall Roof Maintenance Checklist
What to Check Before Northeast Philadelphia Winter Locks In
The Somerton PA fall roof maintenance checklist differs from most Philadelphia neighborhoods because Somerton’s housing stock includes both flat-roof row homes and pitched-shingle detached houses, and the pre-winter priorities for each roof type are almost completely different. This checklist covers both.

FLAT ROOF CHECKLIST (ROW HOME OWNERS)
1. Clean and Test Your Drain — October
This is the single most important fall maintenance task for any Somerton flat roof. A clogged drain in winter means ponded water that freezes, expands into a lens of ice against your membrane, and forces its way under seams and parapet counterflashing. By January, that ice lens has done structural damage to the membrane that no amount of summer sun will reverse. Clean the drain strainer completely, remove all debris from the drain sump area, and pour a full five-gallon bucket of water into the drain to confirm free flow before temperatures drop below freezing. DIY difficulty: Low. Call a pro if: the drain doesn’t flow freely after cleaning, or if there is no visible slope toward the drain.
2. Inspect All Membrane Seams for Lifting or Separation
On a dry fall day, walk the full roof surface and look for seam edges that have lifted from the membrane below, bubbles or blisters in the field area, and any visible cracks or exposed substrate. Seam separations that are small in October become significant water entry points in January, when freeze-thaw cycling repeatedly acts on them. DIY difficulty: Low (inspection only). Call a pro for: any visible seam separation or membrane damage.
3. Check All Four Parapet Walls and Cap Flashing
Walk the perimeter and inspect the cap flashing — the metal or membrane material covering the top of the parapet walls. Look for lifted edges, separated seams, or visible gaps where the cap meets the counterflashing below. On the shared-wall side (attached neighbor), check that the counterflashing termination is still sealed at the brick. Any gap at the parapet is a direct water pathway into the wall cavity. DIY difficulty: Low to Moderate (depends on parapet height and access). Call a pro for: any visible gaps or separated counterflashing.
4. Clear All Roof Penetrations and Curbs
Pipes, vents, HVAC equipment, and skylight curbs that penetrate a flat roof are potential leak points if the surrounding flashing has deteriorated. Check that there are no visible gaps between the flashing collar and the penetration. Check that HVAC equipment hasn’t shifted on its curb, which can separate the curb flashing from the membrane below. DIY difficulty: Low. Call a pro for: any visible flashing deterioration around penetrations.

SHINGLE ROOF CHECKLIST (DETACHED HOME OWNERS)
5. Gutter Cleaning and Inspection — Late October/November
After leaves have fallen (mid-to-late October in Northeast Philadelphia), clean gutters of all debris. Clogged gutters prevent snowmelt from draining, creating the standing water at the eave that freezes into ice dams and forces water under shingles. While cleaning, look for: separated gutter seams, sagging sections due to failed hangers, and significant granule deposits (heavy granule accumulation indicates shingles nearing the end of their life). DIY difficulty: Low. Call a pro if there are seam failures, hanger failures, or heavy granule deposits.
6. Visual Shingle Inspection from the Ground
With binoculars, walk the perimeter and look for: missing or lifted shingles, curling edges or cupping, dark patches indicating granule loss, and any visible sagging in the roof plane. DIY difficulty: Low (ground level only). Call a pro if: any of these conditions are visible.
7. Attic Check for Moisture and Ventilation
On a sunny day, check your attic for daylight through the deck, dark staining on rafters, and adequate insulation coverage. Inadequate attic ventilation in a Philadelphia winter creates a heat differential that melts roof snow, which then refreezes along the cold eaves as ice dams. DIY difficulty: Moderate (inspection is DIY; findings require a pro). Call a pro for: any daylight, staining, or ventilation gaps.
When to Call Paragon Exterior Before Winter
For flat roofs: any drainage issues, seam separation, or parapet flashing gaps warrant a professional visit before December. For shingle roofs: missing shingles, visible curling or cupping across multiple planes, attic staining, or granule accumulation in the gutters all warrant a professional inspection before the first freeze. Free inspections for all Somerton and Northeast Philadelphia homeowners. Call (215) 799-7663.

Frequently Asked Questions
When should I schedule my fall roof inspection in Somerton PA?
Mid-October through November — late enough for most leaves to have fallen so drainage can be fully assessed, early enough to complete repairs before Philadelphia’s first hard freeze. For flat roofs with drain concerns, earlier is always better.
What’s the most important fall maintenance task for a Somerton row home flat roof?
Cleaning and testing the drain. A clogged drain means ponded water that freezes and forces its way under membrane seams and parapet flashing — the leading cause of interior winter leaks in Northeast Philadelphia row homes. Clean the drain strainer and confirm free flow with a bucket of water before temperatures drop.
