Roof Leak Repair Chicago, IL

Roof leak repair in the Chicago area starts with finding where the water actually gets in. We trace it, stop it, and fix the cause, whether that’s flashing, a vent boot, a valley or an ice dam.

Water rarely comes in where the stain shows up. It runs along decking and rafters before it drips, so roof leak repair starts with tracing the water back to where it actually enters.

A roof leak can look small from inside and still be soaking insulation and decking out of sight. Finding the entry point, whether flashing, a vent boot, a valley or an ice dam, is the job.

Most leaks we trace come from a handful of places: flashing at walls and chimneys, vent pipe boots, valleys, skylights, and ice dams at the eaves in winter.

Our Roof Leak Repair Process

Trace the water We start in the attic, follow the staining upslope, then match it to what we see on the roof surface.
Stop active water If it's actively leaking, we protect the area so the inside of your home stops taking water.
Fix the entry point Flashing, boots, valley metal or shingles are replaced, not just sealed over with caulk.
Check after the next rain We tell you what to watch for and come back if the stain grows.

Roof Leak Repair by Type of Home

The northwest suburbs have every kind of house, and each one needs roof leak repair handled a little differently:

Post-war ranches: Long, low ranch rooflines often still sit on their original 1950s or 1960s board decking. We regularly find two layers of shingles, undersized attic ventilation and low-slope additions that were never flashed properly into the main roof.
Split-levels and raised ranches: Split-levels and raised ranches have roof planes that run into sidewalls. That means step flashing and kick-out flashing, and those wall-to-roof joints are where many of the leaks we trace actually begin.
Two-story homes: Two-story homes mean tall eaves, long gutter runs and steeper pitches. Safety staging and careful valley work matter more, and wind takes a bigger toll on high, exposed slopes.
Townhomes and HOA communities: Townhome and condominium associations often control shingle color and style, and attached buildings share roof sections, so the work has to be coordinated with the association and the neighbors.
Older homes near downtowns: Older homes near downtown often have steeper pitches, chimneys, dormers and original plank decking. Chimney flashing and soft spots in old boards are common findings.
1990s and 2000s subdivisions: Subdivisions from the 1990s and 2000s were usually roofed with builder-grade shingles and minimal ventilation, and many of those original roofs are now reaching the end of their life all at once.
Estate homes: Estate homes have large, complex roofs with many valleys, hips, dormers, skylights and steep pitches. Every additional penetration and valley is a place that needs careful flashing, and the roof has to be planned before work begins.

How We Do Roof Leak Repair Right

How water travels

Water that gets past the shingles runs along the underside of the decking and down rafters before it drips onto the ceiling drywall. A stain in the middle of a room can start several feet upslope. That’s why we trace leaks from the attic before touching the roof.

Ice dams and winter leaks

When warm attic air melts snow on the upper roof, the water refreezes at the cold eaves and forms a dam. Meltwater backs up behind it and works under the shingles. Ice and water shield at the eaves protects the deck, and good attic ventilation and insulation stop the melting that causes the dam in the first place.

Condensation vs. roof leaks

In a poorly vented attic, warm, moist air from the house condenses on the cold underside of the decking in winter, then drips like a leak. The fix there is ventilation and air sealing, not new shingles. Knowing the difference saves money.

What to Expect

On the day of the job we protect landscaping and the driveway, set up safety equipment and keep the site organized. At the end we run magnetic sweeps for nails and walk the finished work with you.

We tell you what time the crew arrives, what to move away from the house and how long the work will take. When we’re done, the yard is swept for nails and you get before-and-after photos.

What Affects the Cost of Roof Leak Repair

where the water is entering (a vent boot is simpler than chimney flashing)
how far the water has traveled into decking and insulation
whether the leak is caused by ice dams and needs ventilation or ice and water shield fixes
access, pitch and roof height
whether interior repairs are needed afterward

Repair or Replace?

A roof with damage on one slope and sound shingles everywhere else is a repair. A roof with curling, granule loss or leaks on several slopes, or one that is near the end of its expected life, usually makes more sense to replace. Repeated repairs on a failing roof cost more over time than a new roof. We’ll show you the photos and give you an honest recommendation either way.

Weather in Northern Illinois

Northern Illinois roofs work hard: hail and straight-line winds in spring and summer, heavy snow, and dozens of freeze-thaw cycles every winter. Ice dams at the eaves are one of the most common causes of winter leaks we see.

The freeze-thaw cycle is tough on roofs here. Water gets into small gaps, freezes, expands and opens them wider. Add summer hail and gusty storms, and a roof that looked fine in October can be leaking by March.

Roof Leak Repair: FAQ

Why does my roof only leak in winter?

Winter-only leaks usually come from ice dams. Heat escaping into the attic melts snow, the water refreezes at the cold eaves, and the backed-up meltwater works under the shingles. The fix combines proper ice and water shield at the eaves with attic ventilation and insulation.

Can you fix a leak in the rain?

We can protect the area to stop water coming in. A permanent repair needs a dry surface, so we schedule it for the first workable day.

Is a ceiling stain always a roof leak?

Not always. Bathroom fan ducts, condensation in a poorly vented attic and plumbing can all leave stains. Tracing it is how we know whether the roof is the cause.

What should I do while waiting for repair?

Move belongings, catch drips, and if a ceiling is bulging with water, puncture it carefully to drain it into a bucket. Then call us.

Will my homeowners insurance cover a leak?

Sudden damage from a covered event may be covered. Leaks from wear or poor maintenance usually aren't. We document the cause either way.
