The Call: "I Think My Gutters Just Need Cleaning"

A homeowner in the Chesterfield area of West Valley City reached out in early spring, a few weeks after the last snowpack had finally let go. The complaint sounded routine at first: paint bubbling and peeling on the interior walls near the eaves, mostly on the rear side of the house. The homeowner's working theory was simple — clogged gutters had backed up over winter, and the fascia boards probably needed a fresh coat of paint. A quick gutter flush and a weekend with a brush, and things would be fine.

We hear this often. It's an understandable read. But paint failure at the eave line, especially after a winter with repeated heavy-snow-then-warm-spell cycles, is one of the clearest early warning signs of ice dam damage in West Valley City homes. We asked to come out and take a look at the full picture before anyone picked up a paintbrush.

The home itself is a mid-2000s two-story with standard 12-inch overhangs. The rear slope faces north and stays shaded and cold well into March — exactly the geometry that sets up chronic ice dam formation.

What We Found On Site: The Damage Behind the Drywall

Standing in the attic with a flashlight, the story told itself quickly.

Attic insulation was thin and unevenly distributed, with several bypasses — gaps around ceiling penetrations and top-plate intersections — that were allowing conditioned air to migrate freely into the attic cavity. That warm air was heating the roof deck from below. On cold nights, the deck stayed just warm enough to melt the bottom layer of snowpack. That meltwater ran down toward the eaves, hit the cold overhang (which sits beyond the insulated envelope and stays at ambient temperature), and refroze. Cycle after cycle through January and February, the ice dam at the eave line grew thick enough to pond standing meltwater behind it.

Here's where the roofing side of the problem came in. The existing self-adhering ice-and-water shield membrane — the rubberized underlayment installed under the shingles at the eave — terminated well short of the interior wall line. Code sets a minimum, but on this roof the membrane didn't extend far enough inward to intercept water that had backed up under the first course of shingles. Meltwater found its way beneath the shingles, beneath the membrane termination, and directly onto the roof decking above the exterior wall's top plate.

The decking at the eaves showed significant dark staining and, in two sections, early delamination — the plywood layers beginning to separate from repeated wetting and drying. The top plate of the exterior wall was saturated. That moisture had wicked into the wall cavity and eventually telegraphed itself as the paint failure the homeowner had noticed inside.

The gutters, for the record, were fine.

This is the diagnostic reality of ice dam damage in West Valley City: the interior symptom often shows up far from where the water entered, and it shows up months after the ice has melted. By the time paint is peeling, the structural framing has already been wet for a long time.

How We Fixed It: Full Tear-Off and a Proper Membrane Extension

We scoped the project as a full tear-off — no overlay. Overlaying shingles over compromised decking is a short-term patch that doesn't address the substrate, and it would have locked in the delaminated sections.

Scope of work:

• Full tear-off of existing shingles and underlayment down to the deck.
• Decking replacement at the eave sections showing delamination — new OSB panels, properly fastened and edge-sealed.
• Extended ice-and-water shield installation. This is the critical detail. Rather than stopping at code minimum, we ran the self-adhering membrane a full 24 inches inside the interior wall line. That puts the membrane termination well clear of any realistic ice dam backup scenario on a 12-inch overhang. The membrane is self-sealing around fasteners, so it performs as a continuous waterproof layer even if meltwater backs up aggressively.
• Synthetic underlayment over the field of the roof above the membrane zone.
• New architectural shingles — a dimensional product with a manufacturer's warranty appropriate to the slope and exposure.
• New drip edge at both eave and rake, properly integrated with the membrane and underlayment sequencing.

We also walked the homeowner through what we found in the attic and made a direct referral to an insulation contractor. This is not optional advice. A new roof alone will not stop ice dams. The ice dam is a symptom. The cause is heat escaping through the roof deck because of inadequate insulation and unsealed air bypasses. Address the roofing side without addressing the attic, and within a few winters the new shingles will be sitting on top of the same ice dam cycle. The insulation contractor would assess the bypasses, add blown-in insulation to the appropriate R-value for the climate zone, and air-seal the penetrations at the top plate — the only permanent solution.

What to Watch For: Early Warning Signs of Ice Dam Damage

If you own a home in West Valley City — especially a two-story with north-facing slopes or shallow overhangs — here are the signals worth taking seriously before damage reaches the wall framing:

Interior wall staining or paint failure near the eaves. This is the most common presenting symptom of ice dam damage in West Valley City homes, and it almost always means water has already been in the wall cavity for at least one season.

Visible ice ridges at the eave line during winter. A thick ice buildup at the gutter line, with icicles hanging from it, is a dam in progress. Water is ponding behind it.

Attic frost or condensation on the underside of the deck. If you can safely access your attic after a cold snap and see frost on the sheathing, warm air is escaping from the living space below.

Staining on the soffit or fascia. Exterior staining in this location often means water has been running behind the fascia, not just over the gutter.

None of these symptoms fix themselves. And none of them are solved by cleaning gutters or repainting fascia boards. Ice dam damage in West Valley City homes requires a proper diagnosis — attic, deck, and membrane — before any repair scope is set.
