Mike Groff Roofing | Roofing Services in Myerstown, PA 17067

In our area, shingle curling is often caused by thermal expansion and contraction from our seasonal temperature changes, or from poor attic ventilation trapping excess heat and moisture. At Mike Groff Roofing, we first diagnose the root cause—whether it's ventilation, aging materials, or improper installation. For a localized issue, we can perform precise repairs and replace the affected shingles. If the problem is widespread or due to ventilation, we'll recommend a solution to protect the entire roof system and prevent a recurrence.

Preventing ice dams starts with keeping your entire roof cold. The key is proper attic insulation and ventilation, which stops heat from your living space from melting snow unevenly on the roof. We recommend a professional attic inspection. Mike Groff Roofing can assess your current setup, add insulation where needed, and ensure soffit and ridge vents are clear and functioning. We can also install ice and water shield—a waterproof membrane—along the eaves during a repair or replacement for an extra layer of protection against any dam-related water intrusion.

Addressing both issues starts with a comprehensive inspection. Ice dam damage often causes water infiltration in the eaves and walls, which is a priority to stop. We typically recommend sealing any active leaks first to prevent interior damage. Then, we assess the overall roof health. Often, these combined problems indicate an underlying ventilation issue. Our team will provide a clear plan that may involve targeted repairs for water damage, addressing the attic ventilation to prevent future ice dams, and replacing the compromised shingles to restore your roof's integrity and appearance.
