Roofing & Siding Contractors in Philadelphia
Roofing and siding contractors in Philadelphia and the Delaware Valley. Philadelphia's 200,000+ historic rowhouses, nor'easter snow and wind exposure including the 2010 Snowmageddon 28-inch event, humid summers with algae growth, and enormous suburban counties (Montgomery, Bucks, Delaware, Chester) with massive 1950s–1980s housing inventory create one of the East Coast's largest and most diverse exterior contractor markets.
Philadelphia Roofing — 200,000 Historic Rowhouses, Snowmageddon Nor'easters, Humid Summers, and the Delaware Valley's Enormous Suburban Market
Philadelphia presents one of the most complex and high-volume roofing markets on the East Coast — combining an extraordinary historic housing inventory with massive surrounding suburban development and significant storm exposure. The city's 200,000+ rowhouses span every era from 18th-century Federal architecture in Society Hill and Old City to the 20th-century rowhome neighborhoods of Northeast Philadelphia, South Philadelphia, Kensington, Frankford, and Germantown. Like Baltimore, Philadelphia's urban rowhouses are predominantly flat or very-low-slope roof systems requiring membrane expertise (EPDM, modified bitumen), not standard shingle installation. The February 2010 Snowmageddon dropped 28 inches on Philadelphia over two storms — the largest multi-day snowfall in the city's modern history — causing widespread flat-roof failures in older commercial and residential buildings and driving one of the city's largest insurance claim surges. Philadelphia's summer humidity (ranking among the most humid major cities in the US by specific humidity) drives algae and moss growth on north-facing and shaded roof sections, degrading granule adhesion and shortening effective shingle life in suburban areas. The Philadelphia suburban ring — Montgomery County (Norristown, Lansdale, Blue Bell, Horsham, Doylestown area), Bucks County (Levittown, Bristol, Newtown), Delaware County (Chester, Ridley, Springfield), and Chester County (West Chester, Exton, Malvern) — contains an enormous 1950s–1980s housing inventory from the post-war suburban expansion, with Levittown (Bucks County) representing one of the largest planned housing communities in American history.

Frequently Asked Questions — Philadelphia
What roofing type do Philadelphia rowhouses have?
Philadelphia's historic rowhouses fall into two main categories. The older neighborhoods — Society Hill, Old City, Northern Liberties, Queen Village — have Federal and Georgian-era flat roofs with parapet walls, typically requiring built-up membrane systems (original pitch-and-gravel, now replaced with modified bitumen or EPDM). The larger-scale 20th-century neighborhoods (South Philly, Northeast Philly, Kensington, Frankford, Germantown) also predominantly have flat or minimal-pitch roofing systems. True pitched roofing is more common in the twin-house and semi-detached neighborhoods and in the immediate suburban ring (Ardmore, Haverford, Overbrook). Before assuming a property needs shingle work, it's worth confirming the roof type — many Philadelphia urban jobs require membrane expertise.
What was the Philadelphia Snowmageddon of 2010?
The February 2010 Snowmageddon events struck Philadelphia in two back-to-back nor'easters: February 5–6 (28 inches) and February 9–10 (10–16 inches additional) — total accumulations of 38–44 inches in a single week in parts of the Philadelphia suburbs. The combined snow load was the largest in the region since 1996 and caused widespread flat roof failures across the Philadelphia area. Insurance roofing claims in the Delaware Valley from the 2010 winter storms exceeded $1 billion across Pennsylvania, New Jersey, and Delaware combined.
How does Levittown affect the Philadelphia roofing market?
Levittown (Bucks County, Pennsylvania) is one of the largest planned post-WWII residential communities in American history — developer William Levitt built approximately 17,000 homes in the Levittown PA development starting in 1952. Today, Levittown and neighboring Bristol Township communities contain an extraordinary concentration of 1950s–1970s housing — nearly all now on their second or third roofing cycle. Levittown's homes have simple cape-cod and ranch rooflines that make them efficient replacement jobs; the sheer density and age of the community creates consistent demand. Bristol, Bensalem, Feasterville, and the surrounding lower Bucks County communities have similar vintage inventory.
