The biggest mistake homeowners make is assuming the leak is “right above the stain.” Water travels. Boise roof leaks usually come from predictable weak points—especially during wind and winter conditions.

Top Leak Causes

Most Boise roof leaks come from:

• flashing failures (chimneys, walls, valleys)

• damaged vent boots/penetrations

• wind-lifted shingles

• ice dams and snow melt backup

• old seal failures around skylights/vents

Flashing Failures (Chimneys, Walls, Valleys)

Flashing is where roofs meet things that aren’t roof-shaped. If flashing separates or was installed wrong, water gets in fast.

Signs:

• stains near chimney walls

• leaks during wind-driven rain

• recurring leaks in the same zone

Roof Penetrations (Vents, Bathroom Fans, Skylights)

Vent boots crack with age. Sealant dries. Skylight flashing fails.
These are often repairable—especially if caught early.

Wind-Lifted Shingles and Ridge Caps

Boise wind can lift shingle edges and break adhesive seals. Even if the roof “looks okay,” it may be compromised. The next storm exposes it.

Ice Dams and Snow Melt Paths

Snow melt can back water up under shingles. Poor attic ventilation increases the risk. Ice dams often cause leaks near eaves and exterior walls.

Why the Stain Isn’t the Entry Point

Water can travel along rafters, ductwork, and insulation. That’s why a roofer may inspect areas that seem “far away” from the drip.

What to Tell a Roofer (So Diagnosis Is Faster)

• When it leaks (heavy rain, wind, snow melt)

• Where it shows up (ceiling center, exterior wall, near chimney)

• Whether it’s new or recurring

• Any recent storm event timing

FAQ

• Can a roofer find the leak quickly? Often yes with attic + roof inspection.

• Is sealant a permanent fix? Rarely. It’s usually temporary.

• Do small leaks matter? Yes—hidden moisture causes big repairs.

• What if it only leaks in winter? Likely ice dam/ventilation/flashing issues.
