Roofing

Felt underlayment lasting just 15 to 20 years, against shingles rated for 25 to 30, means the layer you never see can fail years before the one you do.

Most roof problems that show up as ceiling stains didn’t start with a failed shingle at all; they started with this hidden layer beneath it.

A resealed joint and a replaced section solve two completely different problems, and using the wrong one wastes money without actually fixing anything.

Two roofs with identical shingles can need flashing attention decades apart, purely because of which specific metal was chosen for this one component.

Step, valley, counter, and chimney flashing each fail differently in the details, but they all share the exact same underlying vulnerability at their core.

Knowing whether your valley is open metal, woven, or closed-cut immediately narrows down what’s actually gone wrong, since each type ages in its own way.

A chimney wide enough acts exactly like a dam facing thousands of gallons of water during a storm, and this small peaked structure exists to prevent that.

An open metal valley can outlast a closed-cut one by decades, since one relies on durable metal while the other relies on the shingles themselves.

Step flashing handles the roof side of the connection; counterflashing handles the wall side, and each is free to move without disturbing the other.

The staggered, individual-piece design isn’t a shortcut; it’s specifically what lets this flashing handle thermal movement without cracking or pulling loose.
