Cornerstone Builders | General Contractors & Roofing in Lancaster, PA 17601

Absolutely. While a deck or addition itself doesn't fix a roof, proper construction is key. At Cornerstone Builders, we ensure any new structure integrates seamlessly with your existing roof. We meticulously flash around penetrations and tie into your home's drainage system, preventing water intrusion that can lead to leaks, especially during our snowy winters and wet springs.

It's possible. In Lancaster, winter damage often affects both. Heavy snow and ice can stress your roof's structure and drainage. If gutters are clogged or damaged, overflow can pour directly onto your deck, accelerating wood rot and fastener corrosion. Our repair service includes assessing water flow from your roof to prevent recurring deck damage and protect your home's foundation.

We generally recommend addressing the roof first. A compromised roof allows water to damage the underlying structure, including walls and, potentially, deck attachments. By securing your roof—especially fixing common issues like ridge cap damage or leaks—you create a dry starting point. Then, we can safely replace your deck with materials and a design built to last through Lancaster's seasons.
