Roof Leak Repair in Downers Grove, Naperville and DuPage County

Yes, Adept Construction repairs roof leaks in Downers Grove, Naperville and across DuPage County, and we fix where the water gets in, not just where it shows up. A ceiling stain is rarely directly under the problem. We trace it back to the entry point, most often a pipe boot, chimney or skylight flashing, a nail pop or a valley, and repair the source.

Most leak repairs are done in one visit and scheduled within the week. A leak running during rain, or an opening from a fallen limb, is tarped within 24 hours. Every repair starts with a free roof inspection and a written, itemized estimate, and carries our 10-year workmanship warranty. Leaking now? Call (630) 360-2730.

Pipe boots

The rubber collar around a plumbing vent cracks with age and freeze-thaw cycles and is one of the most common sources of a small ceiling stain. We replace the boot rather than cover it with caulk, which fails again within a few seasons.

Chimney and skylight flashing

Failed step flashing, counter-flashing and cracked chimney crowns are behind most persistent leaks on homes built before 2000. We reseal, re-flash or replace. See our chimney flashing repair guide.

Valleys

Valleys carry more water than any other part of the roof and fail first when the metal or the shingle overlap does. Our roof valley repair guide covers the common failures.

Nail pops and wind-lifted shingles

Backed-out nails push up through the shingle above them, and wind breaks the seal strip and creases the shingle mat. A creased shingle can lie flat and still leak at the next heavy rain. We repair the source and replace the damaged shingles.

Ice dams

Ice at the eaves backs meltwater under the shingles and into the wall. We repair the underlayment and shingles at the eave and, with ice-and-water shield and ventilation, keep it from recurring. See ice dam damage and insurance.

Flat and low-slope roofs

On EPDM, TPO and modified bitumen roofs, leaks come from seam failures, punctures, ponding water and failed flashing. See flat roofing and commercial roofing.

Gutters

Sagging, separated or overflowing gutters push water back under the first course of shingles. We re-hang, reseal and replace runs alongside the roof repair.

1. Tell us what you are seeing. A stain, a drip, shingles in the yard. Send a photo if you have one. Storm and leak calls are prioritized.
2. Stop the water. If the leak is active during rain or the roof is open, we tarp and secure it within 24 hours. Emergency tarping is documented so its cost can go on an insurance claim.
3. Trace the leak. We follow the water from the interior stain back to the entry point, at no charge.
4. Price it in writing. You get a written, itemized estimate before any work starts.
5. Repair the source. We replace the pipe boot, re-flash the chimney or skylight, replace the damaged shingles or reseal the membrane. If we open the roof and find more than expected, such as soft or wet decking, we stop and show you before continuing.
6. Back it with a warranty. The repair carries our 10-year workmanship warranty in writing, in addition to any manufacturer warranty on the materials.

Leaks here follow the calendar. In winter, ice dams back meltwater under the shingles at the eaves, and repeated freezing and thawing cracks pipe boots and dries out sealants. In summer the rain comes hard: August is the wettest month in DuPage County, averaging 4.60 inches at Wheaton, the county seat, and that is when flashing gaps and lifted shingles show up as fresh ceiling stains.

The National Weather Service Chicago forecast office issues severe thunderstorm warnings for DuPage County when a storm produces hail of one inch or more or wind gusts of 58 mph or more. Wind-creased and hail-bruised shingles often hold for a season or two and then leak, which is why many of the leaks we trace in spring started with the previous summer’s storms.

Many Naperville homes built in the 1980s and ’90s are at the age when step flashing and chimney crowns fail, and the mature tree canopy in Downers Grove and Hinsdale makes limb strikes a common cause of sudden leaks. Whether a repair in Naperville needs a permit depends on the material. The City of Naperville does not require one for asphalt shingle work on a single-family home as long as the existing roof sheathing stays in place; metal, wood and sealed-membrane roofs need a permit, and the shingle exemption no longer applies once sheathing is replaced. In every case the roofer must hold an Illinois roofing license. We check the rule and pull the permit when one is needed.
