Frequently Asked Questions

Winter snow melts during the day and refreezes at night, causing ice to expand under shingles and lift them. This cycle creates gaps where wind-driven rain penetrates, leading to leaks and accelerated deterioration. Proper attic ventilation and ice barrier installation reduce this damage in Philadelphia's climate.

Flashing replacement is needed when rust has created holes, metal has separated from sealed joints, or repeated repairs have failed within two years. Patching corroded flashing delays leaks temporarily but doesn't address metal fatigue. Chimney and valley flashing typically fail first due to constant water exposure.

Six-inch gutters handle 50% more water volume than 5-inch systems, making them necessary for steep roof pitches, large roof areas, or properties with heavy tree cover. Philadelphia's intense summer storms often overwhelm undersized gutters. Measure your roof area and pitch to determine which size prevents overflow during peak rainfall.

Missing shingles, dented flashing, cracked vents, or visible granule loss across multiple roof sections typically justify claims. Hail creates uniform circular bruising while wind damage appears as random tears or uplift. Document damage with photos before temporary repairs, as insurers require evidence of initial impact.

Ponding happens when drainage slopes are less than 1/4 inch per foot or drains become clogged with debris. Standing water degrades roofing membranes, accelerates UV damage, and adds structural load during winter freezes. Flat roofs in Philadelphia need functioning drainage since seasonal storms can deposit several inches of water quickly.

Board and batten requires flat, solid backing to prevent warping and ensure proper fastening. Installing over deteriorated siding traps moisture and creates uneven surfaces that compromise appearance and durability. Remove existing siding when wood rot, insect damage, or moisture intrusion is present underneath.

Replacing damaged flashing, sealing exposed nail heads, securing lifted shingles, and clearing debris from valleys prevent localized failures from spreading. These repairs add years when the majority of shingles remain intact and granule loss is minimal. Roofs lose functionality from specific failure points, not uniform aging across all shingles.

Seamless gutters eliminate joints where sectional systems leak as sealant degrades and metal contracts during temperature swings. Custom fabrication creates continuous runs fitted to exact measurements, reducing failure points by 80%. Corners and downspout connections remain the only potential leak locations in seamless installations.

Inspections check shingle integrity, flashing condition, vent damage, gutter attachment, and interior ceiling stains. Inspectors document granule displacement patterns that indicate hail impact, photograph missing or creased shingles, and test flashing seals around chimneys and skylights. This documentation supports insurance claims and identifies hidden damage not visible from the ground.

TPO reflects more sunlight and resists ponding water better, while EPDM handles temperature extremes and remains flexible in cold weather. TPO seams are heat-welded for stronger bonds; EPDM uses adhesive or tape seams. Building use, roof access needs, and existing insulation determine which membrane performs better long-term.

Active leaks during rain, missing shingles exposing underlayment, sagging sections, or daylight visible through the attic require urgent response. Water stains that grow between storms indicate ongoing penetration causing structural damage. Temporary tarping prevents interior damage while permanent repairs are scheduled.

Ventilation removes heat that accelerates shingle aging and moisture that causes wood rot in roof decking. Philadelphia's humid summers create attic temperatures exceeding 150 degrees without airflow, baking shingles from underneath. Balanced intake and exhaust ventilation keeps attic temperatures within 10-15 degrees of outside air, preventing premature failure.
