Iredell and Rowan County Roof Replacement: Underlayment

Most of a roof replacement happens out of sight. By the time the shingles are on, the parts that actually keep water out of your house are buried under them. This photo comes from a job in our Iredell and Rowan County service area, and it shows the layer under the shingles: Atlas Summit synthetic underlayment, rolled out and fastened across the whole deck.

What went into this roof

The house is brick with an attached garage. We stripped the old roof down to the deck, then looked at the wood. Where the OSB had gone soft we cut it out and put new sheathing in its place. After that the Summit underlayment went down and got fastened off before any shingles were loaded. On the architectural shingle roof we also set the ridge vent and ran new ridge cap, which is how the attic gets to breathe. A roof replacement in Iredell and Rowan County has to take summer heat and winter wind, and the ridge is where a lot of that gets decided.

Why the underlayment matters

Felt paper tears. It wrinkles when it gets wet and it does not hold a fastener well once wind gets under it. Synthetic underlayment stays flat, holds up to foot traffic during the install, and gives you a real second layer of protection if a shingle ever lifts. It also keeps the house dry during the days the roof is open. Nobody sees it after the job is finished, which is exactly why some roofing companies cut the corner there.

What drives the cost of a new roof

The first question we get is how much is a new roof. The honest answer is that it depends on the size of the roof, the pitch, how many layers are coming off, and how much decking has to be replaced once we can see it. That last one is why we do a free on site inspection before quoting anything. You get a number that holds instead of a guess that grows once the tear off starts. Financing is available if you would rather spread it out, and we pay a $250 referral reward when you send us a neighbor.
