Precision Flashing Repair in Prosser, WA

If your roof is leaking, the shingles are rarely the only culprit. Most water intrusion occurs at the "joints"—the valleys, chimneys, and vents where different planes of your roof meet. At Hometask Roofing, we provide precision flashing repair and replacement to ensure these high-risk areas are hermetically sealed.

In the Yakima Valley, extreme temperature swings cause metal flashing to expand and contract, which can pull nails loose and crack old sealants. Our team uses heavy-gauge galvanized steel or copper to create custom-bent barriers that direct water safely into your gutters rather than into your attic.

The Secondary Defense System

Flashing is your roof's secondary defense. When it fails, water can bypass your shingles entirely and rot your structural decking. We specialize in step-flashing, counter-flashing, and "cricket" installation for chimneys to ensure that even the most complex roof geometries remain 100% watertight.

Frequently Asked Questions

What exactly is "flashing"?
Flashing is thin pieces of impervious material (usually galvanized steel or aluminum) installed to prevent water from passing into a structure from a joint or angle.
Can you just put new sealant over old flashing?
That is usually a temporary patch. For a permanent fix, the old flashing must often be removed so the underlying wood can be inspected and the new metal can be correctly integrated with the shingles.
Why does chimney flashing leak so often?
Chimneys move at a different rate than the roof. If the flashing isn't designed with a "counter-flashing" system that allows for this movement, the seal will eventually break.
