Midvale sits in Salt Lake County with many homes in Old Town Midvale and Bingham Junction built before 1970 that use masonry chimneys tied into asphalt-shingle roofs. Winter temperatures regularly drop below freezing after warm days, so moisture trapped in flue liners expands and cracks the crown or flashing. Roof chimney repair here starts with checking the cricket and step flashing where the chimney meets the roof plane, because those points collect drifting snow that melts and refreezes against the masonry.
Semi-arid summers bake the same roofs, drying out sealant around the counter flashing and creating hairline gaps that let monsoon moisture run down the chimney breast. When we open the roof deck we often find rotted sheathing on the north-facing slopes near Midvale City Park because those areas stay shaded longer. We replace damaged decking with plywood that matches the original thickness, then install new lead step flashing and a stainless-steel rain collar before re-shingling to maintain the existing roof slope and drainage toward the Bingham Junction TRAX Station corridor.
Nearby Murray and West Jordan share the same valley wind patterns that drive fine dust into any unsealed joint. During repair we tape the attic side of the chase to keep insulation from falling into the living space and we always pull the rain cap to inspect the flue tile alignment. This prevents future carbon-monoxide paths once the new flashing is in place.
Homeowners along Union Park Avenue sometimes add solar panels that change roof access. We coordinate panel removal with the installer so the chimney repair does not void the panel warranty, then reinstall the mounting rails after the new flashing is complete.
Technician insight
In Midvale the thing that catches most people out with roof chimney repair is the hidden rot on the north slope of Old Town Midvale roofs; the freeze-thaw cycle from our cold winters pushes water under the flashing long before any interior stain appears.
Old Town Midvale Chimney Leak
Water stains appeared on the ceiling after a January thaw. We found cracked crown mortar and failed step flashing where snow had drifted against the chimney on a 1960s bungalow. We replaced the rotted decking, installed new lead flashing, and repointed the crown so meltwater now sheds cleanly into the gutters.
How it works
- 1
Site Assessment
We arrive at the Midvale address, walk the roof from the ridge to the eaves, and photograph the chimney crown, flashing, and surrounding shingles.
- 2
Flashing and Deck Inspection
We remove shingles around the chimney base, check for rotted sheathing, and test the seal between the flue and the roof deck.
- 3
Repair and Sealing
Damaged decking is replaced, new step flashing and a stainless rain collar are installed, and the crown is parged if cracked.

Final Weatherproofing
Shingles are relaid to match the existing pattern, the rain cap is reset, and the attic side is sealed against dust and insulation migration.
Pricing
Cost depends on the amount of rotted decking found and whether the flue liner also needs attention.
