Flashing, Chimney & Skylight Repair in Billings: Where Metal Roofs Actually Leak

Billings sits at about 3,100 feet in the Yellowstone Valley, tucked below the pale sandstone Rimrocks, and the weather that hits your roof here is not gentle. Heavy wet snow piles up, ice dams form at the eaves, chinook winds swing temperatures 40 degrees in a day, and summer supercells drop hail that pocks shingles and drives water sideways. When a metal roof leaks in Billings, the culprit is almost never the panels themselves. It is the Flashing, Chimney & Skylight Repair in Billings details: the bent metal collars, counterflashing, step flashing, and pan flashing that seal the transitions where the roof meets brick, masonry, glass, and valleys.

We repair and custom-fabricate flashing around chimneys, skylights, valleys, dormers, and brick transitions. Our shop bends metal to the exact profile of your roof, so the fit is watertight instead of caulk-and-hope. If you are chasing a ceiling stain or a drip that only shows up during a thaw, start with our metal roof leak repair page, then let us get the flashing right.

Why Flashing Fails First on Billings Roofs Under Snow and Ice

Billings roof stock is a mix of early-1900s brick and Craftsman homes with steep gables on the South Side, 1950s to 1970s ranches and split-levels across the Heights and Poly Drive, and newer multi-gable homes in the West End and Rehberg Ranch. The older brick chimneys have wide masonry shoulders that collect snow, and the ice that forms there pries at flashing seams. Low-slope ranch roofs hold meltwater longer, and skylight curbs on those roofs take the brunt of it. The failure mode that dominates here is ice dam backup and freeze-thaw movement at masonry transitions, not wind-driven rain.

Ice dams at the eaves push meltwater up under flashing and into the deck.
Chinook temperature swings expand and contract metal, opening old sealant joints.
Brick chimneys wick moisture and rust the original galvanized flashing from behind.
Skylight curbs on 1960s and 1970s ranches crack at the solder seams and weep inside.
Valley flashing on multi-gable West End homes traps pine needles and cottonwood debris.

Every one of those failures shows up as a ceiling stain far from the actual leak, which is why we probe and water-test before we quote. Roofing permits and inspection thresholds vary by jurisdiction, so confirm requirements with the City of Billings building department before work starts.

Key info: A homeowner on the South Side had a stain 12 feet from her brick chimney. The leak was a rusted counterflashing reglet that had been caulked three times. We bent new 24-gauge counterflashing and reset it in the brick mortar joint, and the stain stopped that spring.

For official permit questions, start with the City of Billings website and the Yellowstone County building department.

How We Repair Chimney and Skylight Flashing in Billings

We do not tarp and pray. We open the transition, find where water is actually entering, and rebuild the flashing with metal we bend in-house to match your roof pitch and masonry profile. That matters most on brick chimneys, where a store-bought boot never fits the shoulder correctly. On standing seam roofs, we use seam-mounted or curb-mounted details that do not penetrate the panels.

We inspect the roof, attic, and ceiling stains to trace the actual water path.
We remove failed sealant, old flashing, and any rotted decking or masonry behind it.
We measure and bend new flashing to your exact chimney, curb, or valley profile.
We install step flashing, counterflashing, pan flashing, and ice-and-water shield as needed.
We water-test the repair and photograph it before we close up.

If the leak turns out to be a fastener issue rather than flashing, we route it to our screw replacement and re-fastening service instead of charging you for flashing work you do not need.

Key info: On a 1990s stucco home in Lake Hills, two skylights leaked after every heavy snow. The curb flashing was fine, but the ice dam behind the upper curb was forcing water sideways. We rebuilt the curb with a taller metal pan and added ice-and-water shield upslope, and the ceiling stayed dry through the next two winters.

Flashing Repair Approaches We Use on Billings Roofs

Not every leak calls for the same fix. Here is how we match the approach to the roof, the masonry, and the budget.

Approach	Description	Best for
Custom-bent counterflashing	New metal bent to fit the brick reglet and chimney shoulder, sealed into the mortar joint.	Brick chimneys on older South Side and downtown homes.
Skylight curb rebuild	New metal pan flashing and ice-and-water shield around the curb, with a taller back pan.	Leaking skylights on 1960s to 1990s ranch and split-level roofs.
Valley and step flashing replacement	Open the valley, replace rusted or short flashing, and re-lap the panels correctly.	Multi-gable West End and Rehberg Ranch homes with debris-packed valleys.
Dormer and sidewall flashing	Step flashing and kick-out flashing at siding and stucco transitions.	Dormers and sidewalls on Craftsman and bi-level homes.
Seam-mounted skylight details	Non-penetrating clamps and curb details that leave standing seam panels intact.	Standing seam roofs where panel penetrations are not acceptable.

We choose the least invasive approach that actually stops the water, because every penetration you add is another place ice can find later.

Flashing, Chimney & Skylight Repair Cost in Billings: What to Expect

Most flashing repairs in Billings start at $600 for a single chimney or skylight detail, including the custom-bent metal, sealant, and labor. A straightforward counterflashing replacement on a brick chimney often lands in that range. Skylight curb rebuilds, valley work, and jobs that require opening decking or masonry climb from there, and we quote those after an on-site look.

What moves the price: how much decking or masonry has to be opened, roof pitch and access, whether the roof is standing seam or exposed fastener, how many transitions are leaking, and whether ice-and-water shield has to be added upslope. Older South Side homes with wide brick chimneys take more fabrication time than a newer West End home with a factory skylight curb.

Get two or three estimates, ask each contractor to show you where the water is entering, and be wary of anyone who quotes a flashing repair without getting on the roof. Our full pricing overview lays out how we build numbers.

Frequently asked questions: Flashing, Chimney & Skylight Repair in Billings

How much does Flashing, Chimney & Skylight Repair cost in Billings?

Most single-detail flashing repairs in Billings start at $600, which covers custom-bent metal, sealant, and labor for one chimney or skylight transition. Skylight curb rebuilds and valley work typically run higher because they involve opening decking or re-lapping panels. We give you a firm number after an on-site inspection, not a phone guess.

How do I know if my chimney flashing is leaking in Billings?

Look for ceiling stains near the chimney, rust streaks on the masonry, or water in the attic after a snowmelt. In Billings, the giveaway is a stain that grows during a January thaw or after an ice dam forms at the eaves. If the stain appears far from the chimney, the water is traveling along the deck, so a roof inspection is the only way to confirm.

Can you repair flashing on a standing seam metal roof without voiding it?

Yes. On standing seam we use seam-mounted clamps and curb details that do not penetrate the panels, so the roof's weather seal and warranty stay intact. We bend the flashing in-house to match the seam spacing and panel profile. Exposed-fastener roofs get a different detail with proper lap and fastener placement.

How long does a flashing or skylight repair take?

A single chimney counterflashing repair usually takes half a day. A skylight curb rebuild or a valley replacement often runs a full day, and jobs that uncover rotted decking or masonry can stretch to two days. We tell you the expected window before we start and keep you posted if we find hidden damage.

Do I need a permit for flashing repair in Billings?

A flashing repair by itself often does not require a permit, but rules vary by jurisdiction and by the scope of work. If the repair turns into deck replacement or a partial re-roof, a permit may be triggered. Confirm with the City of Billings building department before work begins, and ask your contractor who is pulling the permit.

What is the difference between flashing repair and a full metal roof replacement?

Flashing repair fixes the transitions where the roof meets chimneys, skylights, valleys, and walls, and it leaves the panels in place. A full replacement removes and reinstalls the entire roof system. If your panels are sound and the leak is isolated to a detail, flashing repair is the right call and costs far less.

When is the best time of year to repair flashing in Billings?

Late spring through early fall is ideal because the roof is dry and sealants cure properly. That said, the demand spike here comes in late winter and early spring, when ice dams and freeze-thaw cycles open flashing seams and homeowners see ceiling stains during the thaw. We repair flashing year-round when conditions allow safe roof access.

Do you handle emergency flashing leaks in Billings?

Yes. If water is actively coming into your home, call (406) 717-6530 and we will schedule a same-day or next-day assessment when possible. We can stop the immediate intrusion and then return to rebuild the flashing properly once the weather allows. Do not wait on an active leak, because the damage compounds fast.

Is the estimate really free and no-obligation?

Yes. We inspect the roof, trace the leak, and give you a written estimate at no charge and with no obligation to book. We tell you what we found, what it takes to fix it, and what it costs. If the repair is minor, we say so rather than upselling a bigger job.

Are you licensed and insured for flashing and skylight repair in Billings?

Yes. You can request a certificate of insurance before work starts, and we recommend you do that with any contractor you hire. Licensed and insured status matters most on roof work, where falls and water damage are real risks.
