Roofing

A roof that’s fine every summer isn’t hiding one hidden winter flaw; it’s facing an entirely different set of conditions that summer never tests at all.

This isn’t always the same leak as an active ice dam; often it’s the delayed release of water that got in and froze solid long before you ever noticed anything.

The leak isn’t really about the snow melting; it’s about where that meltwater goes next, and an ice dam gives it nowhere good to go.

A roof that starts dry and stays dry for hours isn’t necessarily fine; it may simply be filling up toward a threshold that a shorter rain never reaches.

A calm, steady rain tests a roof one way. A thunderstorm tests it four or five different ways at once, all within the same brief, chaotic window.

The entire shedding system assumes water falls down. Wind breaks that assumption by attacking from a direction nothing was ever designed to handle.

A heavy downpour sheets right past the exact same tiny gap that a gentle, sustained drizzle has all the time in the world to work its way through.

A defect that’s too small to leak during the day can open up and leak overnight, purely because the materials around it are contracting in the cold.

The shingles were never the whole waterproofing story to begin with, which is exactly why they can look flawless while water still gets past them.

The stain marks where water finally dripped through, not necessarily where it actually got in, and telling these apart changes the whole repair.
