Shingle roof with new vents and flashing overlooking Dawson Creek

Roof Flashing and Valley Repair

Most roofs don't fail in the middle of a shingle field. They fail at valleys, edges and penetrations. That metal is where we look first.

The metal that keeps your roof honest

We repair and replace roof flashing across Dawson Creek, Fort St John and the South Peace: valley metal, wall and chimney flashing, drip edge, vents and boots. If your leak traces back to tired metal, this is the repair that stops it.

Flashing problems hide in plain sight. The metal loosens, a seal dries out, a boot cracks, and the roof looks fine from the driveway while water works at the wood underneath. A leak that shows up indoors very often started at flashing a season earlier.

Triple waterproofing where it counts

On every roof we build, the spots where roofs actually leak get triple waterproofing: valleys, penetrations and eaves. Repairs get the same thinking. We don't smear sealant at a stain and call it fixed. We open the detail, fix the metal and the layers under it, and put it back the way it should have been done the first time.

And when a detail genuinely calls for a different product, we say so. On Dean's mansion, a flat valley intersection got proper torch-on from a partner we trust instead of shingles forced into a job they can't do. The right product in the right spot is the whole trick.

How a flashing repair goes

Trace the real entry

Flashing leaks rarely show up where the water does. We check the valley metal, wall and chimney flashing, vents and boots above the stain.

Open the detail

The old metal and the layers under it come apart until we hit sound material. Smearing sealant over the top is not a repair.

Metal plus membrane

New flashing goes in over proper membrane, the same triple-waterproofing thinking we build into valleys, penetrations and eaves on new roofs.

Tie it back in

Shingles get woven back so water sheds over the repair, and the work is photo-documented.

Flashing questions

What is flashing, exactly?

The metal that seals your roof wherever it meets something else: valleys, walls, chimneys, vents and skylights. Shingles shed water. Flashing handles the places shingles can't.

Can flashing be fixed without redoing the roof?

Often, yes. Resealing or replacing a run of flashing is routine repair work. The free assessment tells you honestly whether the metal or the roof around it is the problem.

Why do valleys leak first?

Valleys carry more water than any other part of the roof, so wear shows there first. It's why valleys get triple waterproofing on every roof we build.

What's a vent boot and why does it matter?

The rubber seal around pipes coming through your roof. Boots crack as they age, and a cracked boot is one of the cheapest fixes that prevents expensive rot.

Leak keeps coming back?

It's probably the metal, not the shingles. A free assessment finds the real problem and prices the real fix.
