About Harlan & Sons Roofing
Roofing Lancaster, PA Trusts
At Harlan & Sons Roofing, we've worked on the kinds of homes Lancaster County is built on — aging slate, older shingles, brick chimneys, and low-slope additions that collect water in freeze-thaw cycles. When a leak shows up as a ceiling stain or a musty attic, we trace it to the actual source, not just the symptom. We're locally owned, and we back every repair with warrantied workmanship. Lancaster homeowners trust us because we're neighbors who understand what this climate does to a roof year after year.

Frequently Asked Questions
How do you find a roof leak if I can't see obvious damage?
We start with a thorough visual inspection of flashings, valleys, pipe boots, chimney seals, and ridge lines — the spots most likely to fail on Lancaster-area homes. If the source isn't visible, we trace moisture patterns in the attic and use probing to confirm the entry point before any repair begins.
My ceiling is stained but the leak seems to have stopped. Do I still need a repair?
Yes. A stain that looks dry almost always means water has been sitting in your roof deck or insulation. In Lancaster's humid summers and icy winters, that trapped moisture accelerates rot and mold growth even when it isn't actively dripping. We recommend an inspection as soon as you notice any staining.
Can you work with my homeowner's insurance on a leak caused by storm damage?
Absolutely. If the leak is tied to wind, hail, or ice-dam damage, we can document the findings and help you navigate the insurance claim process. We provide detailed inspection reports and photos that make communication with your adjuster straightforward.
How long does a typical leak repair take?
Most residential leak repairs in Lancaster are completed in a single visit once we've confirmed the source. Complex situations — like failed step flashings behind a chimney or widespread shingle deterioration — may require a follow-up appointment, but we'll give you a clear timeline upfront.
What causes most roof leaks on homes in Lancaster County?
The most common culprits we see are cracked or separated flashings around chimneys and dormers, failed pipe-boot seals, and shingle edges that have lifted or curled from Lancaster's repeated freeze-thaw cycles. Older homes with original slate or cedar also develop leak points at nail holes and broken sections over time.
Do you offer any warranty on leak repairs?
Yes. All leak repairs performed by Harlan & Sons Roofing are backed by a workmanship warranty. If the same repair site leaks again within the warranty period, we come back and make it right at no additional cost to you.
