Waukesha Roofing Contractor for Leaks, Ice Dams & Honest Roof Repair

An ice dam is a ridge of ice that forms at the eaves when attic heat melts the snow above it and the water refreezes over the cold overhang. Water then pools behind the ice and works up under the shingles. From there it gets into the decking, walls and ceilings.

Why it's common: Waukesha has a lot of winter days that cross 32°F, so the melt-and-refreeze cycle runs over and over from December through March. The 1950s–70s Cape Cods and ranches in Waukesha, Brookfield and New Berlin make it worse. Many have knee-wall attics, thin insulation and blocked soffit vents that let heat reach the roof deck. Gutters clogged with leaves in the wooded Kettle Moraine areas trap meltwater right at the eave. Roofs installed before ice barrier requirements often have nothing under the shingles to stop the backup.

Locally: We see the most ice dams in Cape Cods off Moreland Boulevard, postwar ranches in Elm Grove and Butler, and wooded homes near Pewaukee Lake. Calls spike in late January and February, especially after a heavy snowfall followed by a sunny warm-up.

Our fix: We steam off the ice safely, stop the active leak, and repair damaged shingles and decking. Then we fix the ventilation, ice barrier or heat cable problems behind it so it doesn't come back.

Hail bruises asphalt shingles, cracks the mat underneath and knocks off the protective granules. Straight-line winds lift shingle tabs, break their seal strips and peel ridge caps. Even when nothing looks wrong from the ground, storm damage cuts years off a roof and often leads to leaks later.

Why it's common: Southeast Wisconsin gets regular severe-weather days from spring through late summer, and derecho-type wind events have crossed the region. Most of Waukesha's 34–36 inches of annual rain falls in these storms. Older 3-tab shingles on subdivision homes in Pewaukee, Sussex and Muskego are especially easy to lift. Storm waves also bring out-of-state contractors knocking on doors. That leaves homeowners needing an honest local assessment and good photos before filing any claim.

Locally: We see the most wind damage on open, exposed lots in Vernon, Genesee Depot and North Prairie. Hail claims cluster in Brookfield and New Berlin subdivisions after summer storm lines move east toward Milwaukee.

Our fix: We inspect slope by slope and photograph every hit. We replace damaged shingles and ridge caps, and we give you documentation you can share with your insurer.

Flashing is the metal and sealant that seals the joint where a roof meets a chimney, skylight, vent pipe or wall. When it pulls loose, cracks or the caulk dries out, water runs straight down into framing, ceilings and fireplace surrounds.

Why it's common: A roof surface here can swing about 150°F between January and July. All that expansion and contraction slowly forces flashing and sealant joints apart. Freeze-thaw cycles pry at old mortar joints in brick chimneys, which are common on Waukesha's historic homes and postwar ranches. Ice dams also back water up around skylights. Many older repairs used only tar or caulk instead of properly woven step and counter flashing, and those shortcuts fail within a few seasons.

Locally: This is common on Victorian and foursquare homes in downtown Waukesha and the McCall Street district. Lake homes on Nagawicka and Okauchee often have multiple skylights, and those fail too. Problems usually show up during spring rains after a hard winter.

Our fix: We remove the failed sealant and install new step and counter flashing, or a cricket behind wide chimneys. We reseal skylight curbs and test the area with water to confirm it's dry.

Builder-grade 3-tab and early architectural shingles have a limited lifespan. Past about 20 years they curl, crack, lose granules and stop sealing, and leaks start popping up in different spots each storm.

Why it's common: Large subdivisions went up across Pewaukee, Sussex, Hartland, Delafield, Muskego and Merton from the 1980s through the 2000s. Many of those roofs are now 20–35 years old and wearing out at the same time. Decades of hot, humid summers and subzero winters speed up how fast asphalt dries out. Homeowners in these neighborhoods often need a straight answer on whether targeted repairs still make financial sense.

Locally: We see this most in Sussex, Hartland and Muskego cul-de-sac neighborhoods and Pewaukee colonials. HOA color rules in many of these subdivisions affect which replacement shingles you can choose.

Our fix: We tell you honestly whether repairs will buy you real time. When replacement makes more sense, we lay out the options, price them upfront, and plan around permit and HOA requirements.

Black algae streaks and green moss grow on shaded, damp roof slopes. Moss holds moisture against shingles and shakes, lifts their edges and speeds up rot. On cedar, it leads to splitting, cupping and soft spots.

Why it's common: Waukesha's humid summers and the heavy tree cover around Pewaukee Lake, Lake Nagawicka, Pine Lake and Okauchee keep north-facing slopes damp for days after rain. Falling leaves and needles pile up in valleys and gutters and hold even more moisture. The lake-area homes with cedar shake roofs are especially vulnerable.

Locally: This is concentrated on wooded lakefront lots in Delafield, Hartland, Nashotah and the Okauchee Lake area, and on Elm Grove's tree-lined streets. North-facing slopes under mature oaks are the usual trouble spots.

Our fix: We gently clean off the growth, replace failing shakes or shingles, clear valleys and gutters, and talk with you about maintenance or protective coatings.

Low-slope EPDM, TPO and modified-bitumen roofs depend on drainage and tight seams. Standing water, open seams, punctures and shrinking membranes all let water into the building below.

Why it's common: Winter snow loads on Waukesha's flat roofs get heavy, especially when wet spring snow lands on old packed snow and drains freeze shut. Over time, freeze-thaw stress opens seams. Heavy summer downpours overwhelm clogged drains and scuppers. Porch roofs and low-slope additions on older homes run into the same problems on a smaller scale.

Locally: We see this on retail and office buildings along the Bluemound Road corridor in Brookfield, light-industrial sites in Waukesha's industrial parks, and porch and garage additions on downtown Waukesha homes.

Our fix: We find and patch membrane failures, reseal seams, clear drainage, and recommend coatings or partial replacement when the membrane can't be saved.

Soffit and fascia boards close off the roof's edge and support the gutters. When ice backup or overflow rots them, moisture gets into the attic, critters find a way in, and the gutters sag. Blocked soffits also choke off the airflow your attic needs.

Why it's common: Ice dams send water behind gutters and into soffits winter after winter. In older Waukesha and Brookfield homes, painted wood fascia from the 1950s–70s often hasn't been maintained in decades. Insulation stuffed against soffit vents is common in postwar homes. It's one of the main reasons those homes get ice dams in the first place.

Locally: This is typical on ranches and Cape Cods in Waukesha, Butler and New Berlin, and on box-gutter Victorians near downtown. Damage usually shows up after spring thaw.

Our fix: We replace rotted wood, install new soffit and fascia, open up ventilation paths, and add ridge or intake vents to keep the attic cold and dry.
