Atlas Summit 60 Underlayment Laid Across a Full Roof Replacement

Most people focus on the shingles. Makes sense - that's what you see every day. But the underlayment beneath them is what actually determines how your roof holds up over time. Skip that step or go cheap on it, and you're setting the whole system up to fail.

We used Atlas Summit 60 synthetic underlayment on this roof replacement, and there's a reason we keep coming back to it. It's a self-adhering, high-performance product that creates a watertight barrier across the entire deck before a single shingle goes down. That means if water ever finds its way past the outer layer, it's got nowhere to go.

You can see the full deck covered clean, edge to edge, with the team still working through the lower sections of the garage roof. Multi-pitch roofs like this one take coordination. Every valley, every transition point, every penetration has to be handled right. That's where a lot of cheaper jobs fall apart - the details at the intersections.

We take the prep seriously because the prep is the job. The shingles are the finish line, but everything under them is what gets you there with confidence. A roof replacement done right should last decades, not just a few years before problems start creeping in. That's the standard we hold ourselves to on every single job.
