Roof leak repair starts with the problem found and photographed, then the scope and price in writing before any work starts.
For roof leak repair in Allentown and 12 towns across Lehigh, Northampton, Bucks, Carbon and 2 more counties, Roofers Hotline takes one call at (855) 512-1072. The line is answered around the clock, and you get a written estimate before work starts.
Storm inspection matters here, with 89 hail reports within 15 km of the city center since 2000 on the Storm Prediction Center's log.
Water often enters well away from the stain you see on the ceiling. The inspection follows it from the attic and across the roof surface. With 5 tornadoes in the county record since 2015, debris damage is worth checking for too. Call to book the inspection and get the source named in writing.
Flashing, pipe boots and valleys are where many leaks start. In the metro, 39.6% of homes were built before 1940, so older roof details and box gutters often need close attention. The written estimate says which of these parts can be resealed and which should be replaced. Call to have them checked.
Once water gets past the shingles, it soaks the underlayment beneath. Hail of up to 2 inches in the county record can crack or bruise shingles, and wet underlayment under them has to come out. The estimate lists each replacement separately. Call to book the visit and see what needs to go.
Water that sits under a roof covering can soften the decking. The metro averages 47 inches of precipitation a year in the 1991 to 2020 normals, so slow leaks have plenty of water to work with. Soft or dark decking goes into the written estimate. Call to have the decking checked.
Step by step, from the first call to the written estimate, the work is explained under roof leak repair explained.
Roof leak repair in Allentown starts with finding where the water gets in, from the attic and from the roof surface, and ends with a written estimate before any work starts. The visit covers flashing, boots, valleys, underlayment, shingles and the decking underneath, plus a moisture check after the repair.
Hail reports within 15 kilometers of the metro, 89 of them from 2000 to 2024, put the town in the Very High band among the towns Roofers Hotline serves. If a stain showed up after a storm, call for roof leak repair here and book the inspection.
NOAA's Storm Events database lists 27 hail events of one inch or more in the county since 2015, with the largest hail at 2 inches. It also lists 5 tornadoes. Hail that size can bruise shingles and loosen the seals around flashing, and a small opening can stay hidden until a heavy rain. So the visit checks the roof surface as well as the spot where the water showed up inside, and the written estimate lists each repair separately. Call to book the inspection after the next storm.

Say you notice a drip or a stain that appears during or after rain. In Allentown, where hail peaks in May and ice dams are a high risk in winter, that stain often traces back to a damaged shingle or sealed joint that let water in. A musty attic, damp insulation and peeling paint below the roofline point to the same problem. Photograph what you see from the ground and do not climb onto the roof. Call, and the inspection will find the source.

Questions
The inspection traces the entry point from both the attic and the roof surface, because water often travels along the decking before it drips. In a town where 83% of homes predate 1980, older flashing is a common source. Call, and the visit ends with a written estimate before any work starts.
Yes, it can. The metro's county logged 27 hail events of one inch or larger since 2015, and damaged shingles or loosened seals may not drip until a heavy rain. If a storm passed through, call for an inspection before the next one arrives.
They can. The metro has a high ice-dam risk, and the 1991 to 2020 normals show about 118 freeze days and 33 inches of snow a year. Water backed up behind ice can get under shingles. If you see water inside, call for an inspection.
Permit rules depend on the scope of the work. The local building code office can tell you what applies, and its number is (610) 437-7690. Pennsylvania also requires roofers to register with the Attorney General's Home Improvement Contractor registry, so look up any contractor there before work begins.
A common question across the metro is Does homeowners insurance cover roof replacement?
