Where Roof Leaks Actually Come From
In our experience across Sandy, the overwhelming majority of leaks trace to one of these — and only a small minority are a failure of the shingle field itself.
| Source | How it shows up | Typical fix |
|---|---|---|
| Pipe boot / vent collar | Stain in a hallway or bathroom ceiling, often a few feet off the plumbing stack | $275 – $650 |
| Chimney or wall flashing | Stain along an interior wall line, worse in wind-driven rain | $500 – $1,600 |
| Valley | Stain appears mid-ceiling during heavy or sustained rain | $700 – $2,200 |
| Ice dam at the eave | Wet spot near an exterior wall, only in winter | $1,200 – $4,500 |
| Skylight | Drip directly at the skylight curb | $550 – $1,800 |
| Nail pops / lifted shingles | Intermittent, hard to reproduce, often wind-dependent | $350 – $900 |
| Gutter overflow behind fascia | Water inside the wall near the eave, not the ceiling | $300 – $1,200 |
| Low-slope section with shingles | Recurring, worsens every year, never fully fixed | Membrane replacement |
What Roofs Actually Cost in Sandy
| Local figure | Typical for Sandy |
|---|---|
| Typical roof size | 18 – 30 squares (Sandy average) |
| Typical full replacement, architectural shingle | $9,500 – $24,000 |
| Housing stock | a wide spread — 1970s and 80s ranches and split-entries in the west, larger custom homes on the east bench toward Bell Canyon and Granite |
| ZIP codes served | 84070, 84092, 84093, 84094 |
The widest spread in the valley. West of State Street it is straightforward asphalt; on the east bench, tile, heavy profiles, and snow-load detailing move the number substantially.
That range assumes a complete tear-off, synthetic underlayment, ice-and-water shield at the eaves and valleys, new flashing, and ridge ventilation. A quote materially below it is usually missing one of those, not finding a cheaper shingle.
What the Timing of Your Leak Tells You
When a leak shows up narrows the cause considerably before anyone gets on the roof.
- New spot each time — the field of the roof is at end of life, not a single failure point.
- Only in heavy, sustained rain — usually a valley or an underlayment issue. Light rain does not build enough volume to overwhelm it.
- Only in wind-driven rain from one direction — flashing on that side, or lifted shingles.
- Only in winter, near an exterior wall — ice damming, not a hole. The roof is fine; the eave detail is not.
- Constant drip long after the rain stops — water is sitting in insulation or on the back of the ceiling and releasing slowly. The entry point may be well uphill.
- Same spot every time, gets worse each year — an unrepaired entry point that is enlarging. This one gets expensive if left.
Actively Leaking Right Now? Do This First
- 1
Move what is underneath
Furniture, electronics, anything absorbent. Bucket under the drip.
- 2
Relieve a bulging ceiling
If drywall is sagging and holding water, put a bucket under it and pierce the low point with a screwdriver. Letting it drain in a controlled spot is far better than a whole section of ceiling coming down at once.
- 3
Kill power to the area if water is near fixtures
Any water near a light fixture, fan, or outlet means shut that circuit off at the panel.
- 4
Photograph everything
Before you clean up. Time-stamped photos are what an insurance adjuster will want, and you cannot recreate them later.
- 5
Do not get on the roof in a storm
Wet shingles, wind, and a ladder is how people get seriously hurt. Nothing on that roof is worth it.

We can usually get a temporary dry-in on the same day in Sandy and come back for the permanent repair once we can work safely.
Roof Repair Costs in Sandy
| Repair | Typical range | Notes |
|---|---|---|
| Pipe boot / vent flashing replacement | $275 – $650 | The single most common leak source on Utah roofs. |
| Replace a section of damaged or missing shingles | $350 – $900 | Assumes a matching shingle is still available. |
| Step or counter flashing repair at a wall or chimney | $500 – $1,600 | Cost rises sharply if stucco or masonry has to be cut. |
| Valley repair or re-line | $700 – $2,200 | Depends on valley length and whether decking under it is wet. |
| Skylight reflash or reseal | $550 – $1,800 | Full skylight replacement runs higher. |
| Ridge or hip cap replacement after wind | $450 – $1,500 | Very common after a spring wind event. |
| Ice dam damage repair (eave rebuild + ice shield) | $1,200 – $4,500 | Bench and canyon-mouth homes see this most. |
| Decking replacement | $85 – $150 per 4x8 sheet | Only known once the old roof is off. Should be a per-sheet line item. |
| Emergency tarp / temporary dry-in | $300 – $850 | Buys time until a permanent repair can be scheduled. |
| Full-slope repair (one plane of the roof) | $2,500 – $6,500 | At this point, compare against a full replacement quote. |
Two things move a repair up its range faster than anything else: how long the water has been getting in, and how hard the area is to reach. A leak caught in the first season is usually a boot and a few shingles. The same leak found two winters later has often taken decking, insulation, and drywall with it.
Roofing in Sandy: What's Different Here
The east side of Sandy is where we see the highest concentration of tile and heavy-profile roofs in the valley, along with a lot of homes carrying real snow load. West of State Street the stock is mostly asphalt shingle and the conversation is usually about age, not material.
Homes above about 5,000 feet on the Sandy bench sit directly in the path of canyon winds off Little Cottonwood, and they hold snow noticeably longer than homes on the valley floor.
Housing here is a wide spread — 1970s and 80s ranches and split-entries in the west, larger custom homes on the east bench toward Bell Canyon and Granite. We work throughout Historic Sandy, Alta View, Willow Creek, Granite, and the rest of Sandy — including everything near America First Field.

Roof Leak Repair FAQs — Sandy
Can you repair just one section?
Yes, and we do it often. The honest caveat is shingle matching — on a roof more than about eight years old, a new patch will not weather-match the surrounding field. On a back slope that is usually fine. On a front elevation it may bother you.
Do you warranty repairs?
Yes. Repairs carry a workmanship warranty on the specific work performed. It does not extend to the rest of an aging roof, and we will tell you plainly at the time if the rest of the roof is likely to need attention soon.
Why can’t anyone find my leak?
Because water travels. It can enter at a ridge or a wall flashing and run along framing for eight or ten feet before it drops through the ceiling. Finding it means working from the entry side, checking every penetration and flashing detail uphill of the stain, and sometimes running a controlled water test.
My roof only leaks in heavy rain. Is that less serious?
Not necessarily — it usually means the volume of water is overwhelming a valley or an underlayment gap that handles light rain fine. It will get worse, and it is doing damage to decking and insulation every time even when nothing shows inside.
It only leaks in winter. Why?
That is almost always ice damming rather than a hole. Meltwater runs down a warm roof, refreezes at the cold eave, backs up under the shingles, and gets in. The fix is a combination of ice-and-water shield at the eaves, correcting attic ventilation, and addressing heat loss into the attic.
Can you tarp it today?
Often, yes, if weather allows us to work safely. A temporary dry-in typically runs $300 to $850 and buys time for a proper repair. Call 385-534-3402 and we will tell you straight whether we can get to you today.
