About Harlan & Sons Roofing

Roofing Lancaster, PA Trusts

A roof leak rarely announces itself where it starts — water travels along rafters and decking before showing up as a stain on your ceiling. At Harlan & Sons Roofing, we use a systematic approach to pinpoint the true source of every leak in Lancaster homes, not just the visible symptom. Once we've found it, our licensed and insured crew makes a durable repair backed by a workmanship warranty, so you're not patching the same spot again next season. Contact us for a no-obligation written estimate and find out exactly what it will take to keep your home dry.

Common questions

Frequently Asked Questions

How do you find where a roof leak is actually coming from?
We start with a thorough visual inspection of your roof's surface, flashing, valleys, and penetrations — the spots most likely to fail. We trace water pathways from the point where you see interior damage back to the true entry point on the roof, which is often several feet away from that ceiling stain.
Can a small leak wait, or should I address it right away?
Even a minor leak should be addressed promptly. In Lancaster's wet springs and cold winters, water that gets under shingles or into the decking accelerates rot and can compromise your roof's structural integrity faster than most homeowners expect.
Will you just patch the spot, or do you repair the underlying problem?
We repair the underlying cause, not just the surface. A proper leak repair means addressing damaged or missing shingles, failed flashing, cracked pipe boots, or deteriorated sealants — whatever is actually letting water in.
What if my leak is in a hard-to-access area like a valley or around a chimney?
Valleys and chimney flashings are among the most common leak sources on Lancaster roofs, and they're exactly what we're trained to handle. Our crew inspects and repairs these detail areas with the same care as any other part of the roof.
Is there a warranty on your leak repair work?
Yes. All of our leak detection and repair work is covered by a workmanship warranty, so if the repaired area causes a problem related to our work, we'll make it right at no additional cost to you.
How much does leak detection and repair typically cost?
Every leak is different — the cost depends on where the leak originates and how much material or labor is involved. That's exactly why we provide a free, no-obligation written estimate before any work begins, so you know the full scope and price upfront.
