What a roofer in Philadelphia actually does

A residential roofer either performs targeted repair (lifted shingles, popped nails, failed flashing, single-leak diagnosis) or a full tear-off and replacement. A reputable contractor will start with a multi-point inspection: shingle condition (granule loss, curling, cracking), flashing integrity around chimneys/sidewalls/penetrations, ridge and soffit ventilation, attic moisture signs, and decking condition (you don't know about rotten plywood until tear-off). Asphalt shingle is the dominant material in 80% of US homes; metal and tile dominate in storm-prone or arid markets. All re-roofs require a permit and at least one mid-roof inspection by the local AHJ in most jurisdictions, and OSHA 1926.501 requires fall protection for any work at heights above 6 feet — a non-negotiable safety/insurance issue.

Questions to ask before you hire in PA

Are you a manufacturer-certified installer (GAF Master Elite, Owens Corning Platinum, CertainTeed Select)? Certification is required for the long manufacturer warranties.
What's the workmanship warranty (separate from the manufacturer's shingle warranty), and is it transferable?
How do you handle decking that's rotten under the old shingles — is it a per-sheet add, and what's the unit price?
Will you tear off the old roof completely (single-layer install only), or are you proposing an overlay?
Are ice & water shield, drip edge, and proper underlayment included to current code in my climate zone?
What's the projected weather window, and what happens if a storm hits mid-job?

Door-to-door storm-chaser pitches, "we just did your neighbor's roof" without proof, asking for full payment up front, no permit pulled, or the company refusing to provide its state contractor license number.

Seasonal roofing checklist for Philadelphia homeowners

Spring

After the last freeze, walk the perimeter and look for shingle granules collected at downspouts — heavy granule loss is the early sign of asphalt shingle wear.
Inspect attic decking for any new daylight, dark stains, or musty smell; small leaks show up in the attic months before they show up on the ceiling.
Trim any branches now overhanging the roof to at least 10 feet of clearance to prevent abrasion and squirrel access.
Check pipe-boot rubber collars — UV cracks them every 8–10 years and they're a top-three leak source.

Fall

Clean gutters and downspouts thoroughly after leaf-drop; clogged gutters cause ice damming and fascia rot all winter.
Inspect and re-seal flashing around chimneys, skylights, and sidewall transitions before freeze-thaw cycles begin.
Schedule any needed repairs now — most reputable roofers stop scheduling work in deep winter except for emergency tarp-and-patch.
Verify attic ventilation (soffit + ridge) is unobstructed; poor venting is the #1 cause of premature shingle failure in the south and ice dams in the north.

Winter

After heavy snow, rake the bottom 3–4 feet of the roof from the ground (snow rake) to prevent ice dam formation at the eave.
Watch interior ceilings for new water stains during the first thaw — that's the moment any compromised flashing or shingle reveals itself.
