Brookfield Roofing Contractor for Wisconsin Winters, Hail and Ice Dams

An ice dam is a ridge of ice that forms at the roof edge. Heat escaping from the attic melts snow higher on the roof, and the meltwater refreezes over the colder eaves. The water pooled behind the dam then works its way under the shingles and into the soffits, walls and ceilings.

With 45–50 inches of snow a year and repeated freeze-thaw cycles from November through March, Brookfield is ideal ice-dam country. The biggest factor is how the house was built. Many 1960s–1980s ranches and split-levels have thin attic insulation, blocked soffit vents and no ice-barrier membrane at the eaves, because those roofs went on before current practice. Cathedral ceilings in larger custom homes often have little or no ventilation space, so heat goes straight into the roof deck.

• Thick icicles hanging from gutters and eaves
• Water stains on ceilings along exterior walls
• Damp or peeling paint on soffits
• Frost or wet insulation in the attic
• Sagging or ice-packed gutters
• Uneven snowmelt patterns on the roof

Ice dams are especially common on 1960s–1980s ranches in Brookfield Hills and Fox River Heights and on cathedral-ceiling homes around Tanglewood and Elm Grove. North-facing eaves shaded by mature trees hold ice the longest.

Our fix: We remove dams safely by steaming, then fix the underlying cause: ice-and-water barrier at the eaves, balanced intake and exhaust ventilation, and attic air sealing and insulation upgrades.

Hail bruises shingles, knocks off their protective granules and fractures the mat underneath. Straight-line winds and derecho gusts lift shingle tabs, break their seal strips and can tear off whole sections. Either kind of damage leaves the roof open to water from the next storm.

Southeast Wisconsin's spring and summer thunderstorms regularly bring large hail and damaging straight-line winds. Derecho-type events can strip shingles off whole neighborhoods. Hail and wind are the main triggers for insurance-claim reroofs in the area. Older 3-tab shingles, which are still common on postwar Brookfield homes, have lower wind ratings and break their seals more easily than modern architectural shingles. Mature tree canopy adds the risk of falling limbs.

• Shingles missing or creased after a storm
• Dents on gutters, downspouts, vents or AC fins
• Granules collecting in downspouts
• Dark circular bruises on shingles
• Exposed underlayment or decking
• Fallen limbs resting on the roof

Storm damage often affects whole streets at once in Brookfield, New Berlin and Menomonee Falls subdivisions. That's when out-of-state storm chasers start going door to door in Elm Grove and along the Moorland Road area.

Our fix: We tarp right away to stop active leaks, document the damage for your insurer, meet the adjuster if needed, and repair or replace the roof in line with Wisconsin's storm-contracting laws.

Flashing is the metal and membrane detailing that seals the spots where the roof meets a chimney, skylight, wall, dormer or valley. When flashing rusts, separates or was installed poorly, water gets behind it, often well before the shingles themselves are worn out.

Brookfield's 1980s–2000s custom homes are full of transitions: many valleys, dormers, turrets and skylights over cathedral ceilings. Seasonal swings of 60 °F or more keep moving metal and sealants until they crack. Original step flashing on older homes has often rusted through, and many brick chimney crowns have deteriorated after decades of freeze-thaw. Reusing old flashing during a reroof is a common shortcut that causes leaks later.

• Stains around skylight frames or wells
• Damp drywall near the chimney chase
• Rust streaks on flashing or siding
• Cracked caulk standing in for real flashing
• Crumbling mortar or chimney crown
• Leaks only during wind-driven rain

We see this most on executive homes in Elm Grove, Tanglewood and the Woodland Prime area with skylights and steep valleys, and on brick-chimney Tudors and Cape Cods in Wauwatosa Village.

Our fix: We replace flashing with new step, counter and valley metal or reflash skylights, rebuild deteriorated chimney crowns when needed, and never rely on caulk as the main seal.

Asphalt shingles slowly lose their granules, dry out and become brittle. Once that happens they curl, crack and stop protecting the deck. A worn roof may not leak yet, but it's heading for widespread failure.

A lot of the Brookfield area's roofs are aging out at the same time. Many 1990s–2000s builder-grade roofs in New Berlin, Franklin, Sussex and Pewaukee were never top-tier products, and UV, humidity and extreme seasonal swings have shortened their lives. Some older homes still carry two layers of 3-tab shingles, which traps heat and hides decking rot.

• Curled, cupped or clawing shingle edges
• Bald patches where granules have worn away
• Cracked or brittle tabs
• More nail pops than before
• A roof older than 20–25 years
• Neighbors on the street reroofing

Builder-grade subdivisions from the 1990s and 2000s in New Berlin, Franklin, Sussex, Germantown and Pewaukee are reaching replacement age together, along with original-era roofs in Brookfield Hills.

Our fix: We do a full tear-off down to the deck, replace any rotted sheathing, add ice barrier and proper ventilation, and install architectural or Class 4 impact-resistant shingles.

Ponding is water that sits on a flat or low-slope roof for more than about 48 hours after rain. Over time it breaks down EPDM, TPO and built-up membranes, finds its way through seams and adds weight to the structure.

The office parks along Bluemound Road and the industrial buildings in New Berlin and Butler mostly use low-slope membranes. Clogged drains, sagging deck sections and settled insulation create low spots. In late winter, heavy wet snow adds load, and when water in those low spots freezes and thaws it opens seams and flashing at curbs and rooftop units.

• Standing water two days after rain
• Dirt rings or algae on the membrane
• Open or lifted seams
• Ceiling tile stains inside
• Blistered or alligatored built-up surfaces
• Leaks around HVAC curbs

This is common on 1970s–1990s office and retail buildings in the Brookfield Square / Bluemound Road corridor and on light-industrial roofs in the New Berlin and Butler industrial parks.

Our fix: We clear drains, repair seams and patches, add tapered insulation or crickets to improve drainage, and replace membranes where they've failed, scheduled around tenant operations.

An attic without balanced intake and exhaust traps heat and moisture. In summer, that heat bakes the shingles from below. In winter, condensation rots the sheathing and fuels ice dams. Manufacturers also require proper ventilation to honor their shingle warranties.

Many original Brookfield homes were built with only a couple of gable or box vents, and later remodels often covered over the soffit intakes. Brookfield's humid summers and long, cold winters push a lot of moisture through the attic every year. Rotted decking is one of the most common surprises we find during tear-offs on 1960s–1980s homes.

• Soft or spongy spots underfoot on the roof
• Frost on nails in the attic in winter
• Musty attic odor or mildew
• Rippled or wavy shingle lines
• Unusually high upstairs cooling bills
• Premature shingle aging

This shows up most in the split-levels and bi-levels of the Town of Brookfield and Fox River Heights, and in older Waukesha and West Allis homes that have been remodeled many times.

Our fix: We assess the attic and design a balanced ventilation plan with soffit intake and ridge exhaust, and we replace damaged decking before installing the new roof.

Black streaks on shingles are usually algae feeding on the limestone filler in the shingle. Moss holds moisture against the roof and lifts shingle edges. Leaves and twigs pack into valleys and gutters and send water where it shouldn't go.

Summer dew points in the 60s–70s, plus the dense tree cover in older neighborhoods, keep north-facing and shaded slopes damp for long stretches. Leaves fill valleys every fall, right before freeze-up, which creates ideal conditions for ice dams and backups.

• Black or green streaks on shingles
• Green moss clumps on shaded slopes
• Valleys packed with leaves
• Overflowing gutters in moderate rain
• Shingle edges lifted by moss
• Seedlings growing in gutters

Wooded lots around Elm Grove, Brookfield Hills, the Pewaukee Lake area and Washington Highlands collect the most debris and growth, especially on north slopes under mature oaks and maples.

Our fix: We do gentle, roof-safe cleaning, clear valleys and gutters, and trim branch contact. Zinc or copper strips and algae-resistant shingles slow regrowth.
