Core One Construction | Roofing Services in Churchville, PA 18966

A proper roof installation is your first line of defense against ice dams. In Churchville, we focus on creating a cold roof system with adequate attic ventilation and insulation to minimize the snow melt-and-refreeze cycle that causes dams. We also install high-quality ice and water shield along the eaves and in valleys, and ensure proper sealing around all penetrations like chimneys, which are frequent leak sources. This comprehensive approach helps prevent the water backup that leads to interior damage.

This is a common overlap we see in our local work. Often, leaks near the roofline, especially after ice dam events, originate from compromised step flashing where the roof meets the siding or from failing chimney flashing. While the siding may show water stains, the root cause is usually the roofing detail. We start with a thorough inspection of the roof-wall intersection and chimney to identify the source. Fixing the underlying flashing is crucial before any siding repair or replacement, ensuring a complete and lasting solution for your home.

For a replacement that tackles persistent chimney leaks, the key is in the details. We use a combination of step flashing integrated with the new shingles and a custom-fabricated counterflashing set into the chimney masonry. This creates a watertight, interlocking seal. We also replace the cricket (a small peaked diversion) behind the chimney if needed, to shed water and snow away. Using premium, flexible sealants and ensuring the masonry is sound are also critical steps in our Churchville-area installations to stop leaks for good.
