What local roofs deal with
Hail, wind and storm history in the county
NOAA's Storm Events database lists 27 hail events of one inch or larger in the county record since 2015, with hail up to 2 inches and 5 tornadoes. The hail season runs April through August, and May is the peak month. Hail bruises shingles and loosens the granules that shield them, and the damage often can't be seen from the ground.
After a hailstorm, call for a roof inspection and ask for the written estimate while the storm dates are fresh.
Housing stock and roof age
By Census estimates for 2019 to 2023, 83% of Allentown homes were built before 1980, compared with 65% across the county. The median home was built in 1951, and 42.3% of homes are owner-occupied. Older houses often have several layers of past roofing, worn flashing and tired decking, so a small leak can point to a larger problem.
If your roof is original or you can't say when it was last replaced, call for an inspection and a written estimate that covers what the roof needs.
Winters, ice dams and snow load
The Allentown airport station recorded 33.1 inches of snow a year and 118 days a year at or below freezing in the 1991 to 2020 climate normals. Roofers Hotline rates ice-dam risk here as High. Melting snow refreezes at the eaves, backs water under shingles and soaks insulation and ceilings. The most recent federal disaster declaration for the county area was a severe winter storm and snowstorm on March 23, 2016.
Check the attic for stains or damp insulation after each thaw, and call for leak repair when you find them.
Codes, permits and licensing in Pennsylvania
Pennsylvania requires home improvement contractors, including roofers, to register with the Attorney General's Home Improvement Contractor registry. Look up any license at the Pennsylvania Attorney General HIC registry. Allentown's building code office handles permit questions at (610) 437-7690, and a replacement may need one.
Before a job starts, ask for the written estimate, and call the code office if you are unsure whether your project needs a permit. Roofers Hotline answers calls 24 hours a day.
Roofers Hotline also books metal roofing in Allentown from the same number, with the inspection photographed before the estimate is written.
