Waterproofing in Lancaster, PA
We handle roof waterproofing and leak prevention across South-Central PA. Every job starts with a free inspection and a written estimate.
Roofs fail at the details, not the middle
Water rarely gets in through the open field of a roof. It gets in at the transitions: flashing at walls and chimneys, valleys where two planes meet, penetrations for vents and pipes, and low-slope sections where water moves slowly.
Those are the same details that ice-and-water membrane and proper flashing are designed to protect, which is why addressing them before they fail costs far less than repairing water damage afterwards.

Questions
Waterproofing, answered
What does roof waterproofing cover?
It focuses on the parts of a roof where water actually gets in: flashing, valleys, penetrations, and low-slope areas. The inspection identifies which of those apply to your roof.
Is waterproofing worth it if my roof is not leaking?
Addressing a vulnerable detail before it fails is generally far cheaper than repairing interior water damage later. We will tell you what we see and let you decide.
Does waterproofing help with ice dams?
An ice-and-water membrane at the eaves is designed to stop water backed up by an ice dam from getting under the shingles. Ventilation and insulation are what address the cause of the dam itself.
Do you offer free inspections?
Yes. Every job starts with a free inspection and a written estimate, with no obligation.
