Common Roofing Problems in Harrisburg

Harrisburg homes face a triple threat: spring hail that bruises asphalt shingles, summer thunderstorms that test step flashing and valley details, and winter ice dams that back water under the eaves. The mixed housing stock—brick colonials from the 1990s alongside newer Craftsman builds—means every roof deck has different vulnerabilities and failure modes.

• Granule loss from hail impact — spring storms send marble-sized hail that dents shingles and strips granules from the surface, exposing the asphalt substrate; water wicks through the exposed areas and decay spreads through the roof deck and framing.
• Ice dams along gutters and eaves — winter freeze-thaw cycles trap ice along the gutter line; water backs up under the shingles and seeps through underlayment and ice-and-water shield failure; interior ceilings show stains months after the thaw.
• Flashing and counter-flashing separation — mortar and sealant around chimney flashing and pipe boots degrade from UV exposure and thermal stress; water seeps around these penetrations instead of being diverted; rot spreads through fascia, soffit, and wood framing.
• Gutter separation and overflow — old brick colonials with vinyl gutters from the 2000s see fasteners rust and gutters sag away from the fascia; debris clogs downspouts; water spills behind the gutter and erodes soffit and rake boards.
• Ridge vent and soffit vent blockage — dust, pollen, and shingle granules clog ridge vents and soffit vents, strangling airflow; moisture and heat accumulate in the attic; roof deck sheathing and trusses swell and curve; premature end-of-life wear follows.
• Sagging roof deck from moisture absorption — prolonged leaks from flashing failure or underlayment breakdown allow plywood sheathing and OSB to absorb water; substrate swells and loses structural integrity; the roof deck visibly sags and creates low spots that trap more water.
• Blistering and peeling asphalt shingles — humid summers combined with attic heat and poor ventilation push moisture up through shingles; tar blister and bubble; shingles peel and curl; high winds lift edges and tear shingles away from nails.
