Adept Construction, Inc. repairs roofs across DuPage County and the neighboring parts of Cook, Will and Kane counties from two offices — 6509 Hathaway Lane in Downers Grove and 27W225 79th Street in Naperville. We fix leaks, storm and hail damage, missing and wind-lifted shingles, failed flashing, ice-dam damage and flat-roof membranes on homes and commercial buildings, and we have done it since 1997 as an Illinois-licensed roofing contractor (No. 104.011123) and Owens Corning Preferred Contractor. Most repairs are scheduled within the week; active leaks and storm openings get emergency tarping first; every repair starts with a free inspection and a written, itemized estimate.
If you are in one of our two home towns, the page written for it has local response times, permit rules and pricing: roof repair in Naperville and roof repair in Downers Grove. We also repair roofs in Villa Park, Hinsdale, Lombard, Wheaton, Aurora, Lemont and Homer Glen — see the full service area.
Leaks, shingles, flashing, valleys, ice dams, flat roofs and more
We trace a leak from the ceiling stain back to the entry point — a pipe boot, chimney or skylight flashing, a nail pop, a valley — and repair the source. Most leak repairs are one visit. See roof leak repair for how we trace and fix leaks. Our roof leak detection guide explains what to look for first.
Missing, cracked, curled or wind-lifted asphalt shingles, replaced individually or by section and color-matched as closely as the original run allows. On a roof past 20 years we tell you plainly whether a repair is worth it.
Hail bruising, wind-lifted shingles and tree-limb strikes, inspected, photographed and documented for your insurance claim. Details on the storm damage page.
Failed step flashing, counter-flashing, cracked crowns and skylight seals are behind most persistent leaks on homes built before 2000; we reseal, re-flash or replace. See our chimney flashing repair guide.
Valleys carry the most water on the roof and fail first when the metal or the shingle overlap does. Our roof valley repair guide covers the common failures.
Lifted shingles and soaked underlayment at the eaves after a DuPage County winter, repaired and — with ice-and-water shield and ventilation — prevented from recurring. See ice dam damage and insurance.
EPDM, TPO and modified bitumen membranes on commercial buildings and flat-roofed additions — seam failures, punctures, ponding and flashing. See flat roofing and our modified bitumen repair guide.
Split or missing shakes and cracked composite tiles, replaced to match. See cedar shake roofing and composite roofing.
A few shingles, a pipe boot, a loose piece of flashing — our handyman roof repair service sends one technician instead of a crew.
Sagging, separated or overflowing gutters push water back under the shingles; we re-hang, reseal and replace runs alongside roof repairs.
The National Weather Service Chicago office in Romeoville issues the severe thunderstorm warnings for DuPage, Will, Cook and Kane counties, and after every warned storm Adept Construction inspects, tarps, documents and repairs roofs across the county. Hail of an inch or more and wind gusts above 60 mph damage asphalt shingles in ways you cannot see from the ground; a fallen limb is obvious. Either way we photograph every hit, write the scope your insurer needs and meet the adjuster on site when asked. The storm damage page explains the process; our guide to roof insurance claims in Illinois explains what adjusters look for.
Adept Construction holds Illinois roofing contractor license No. 104.011123, issued under the Roofing Industry Licensing Act and verifiable on the IDFPR roofing contractor page; carries general liability and workers’ compensation insurance; is an Owens Corning Preferred Contractor; and is BBB Accredited with an A+ rating. Every repair is quoted in writing with the scope itemized before work starts, and carries our 10-year workmanship warranty in addition to any manufacturer warranty on materials. If we open the roof and find more than expected, we stop and show you before continuing.
What to look for before a small problem becomes a big one
Curled, cracked, bald or missing shingles let water under the roof. On a DuPage County asphalt roof this usually starts around year 15 to 20, or after a hail or wind storm at any age.
A stain rarely sits under the leak. Water enters at a flashing, boot or nail, runs along the underlayment or a rafter, and shows up several feet away. We trace it back rather than patching where the stain is.
Coarse black grit in the gutters or at the downspout outlet is shingle surface washing off. A little is normal on a new roof; a lot on an older roof means the shingles are near the end.
Heat building in a poorly vented attic in summer, or escaping through it in winter, shows up on the utility bill before it shows up on the ceiling. Ventilation is checked on every repair visit.
Raccoons, squirrels and birds get in through soft fascia, rotted soffit and lifted shingles. The entry point is a roof repair; the animal is a separate call.
Light through the roof boards means a hole; a sag between rafters means wet, weakened decking. Both are repair-now, not repair-later.
The decision comes down to three things: the age of the roof, how much of its surface is damaged, and whether the damage is one event or a pattern. A roof under 15 years old with one leak, a few missing shingles or a flashing failure gets a repair. A roof past 20 years, shedding granules, with several damaged areas, more than one leak or hail damage across most of its surface is usually better replaced — and if the hail damage is widespread, the replacement is often an insurance claim. Adept Construction inspects at no charge and puts the recommendation in writing; when it is a replacement, our roof replacement service page covers the process.
Damage on less than a quarter of the roof, on a roof that is otherwise sound, is a repair. Damage on more than that, or damage that keeps recurring in new places, means the whole roof is failing at the same rate and repairs will not keep up. Wind can strip shingles from one slope and leave the rest untouched; hail hits every slope facing the storm. We map the damage on the estimate so you can see which case you have.
Yes, in most cases. Replacing a few shingles restores a sound roof after wind or a limb strike, and it is the right call whenever the surrounding shingles are still flexible and holding their granules. The color will not match perfectly — the original run has weathered — and on a roof past 20 years the shingles next to the repair may crack when they are lifted, which is the point at which we tell you a section or the whole roof is the better spend. Adept Construction has repaired and replaced roofs across DuPage County since 1997; we know the age and condition of the housing stock here, and the estimate says which case yours is.
A roof leak does not stay the same size. Water that reaches the decking rots it, water that reaches the insulation ruins it, and water that reaches drywall grows mold within days. A repair that costs a few hundred dollars this month is a decking replacement next season. Call the nearest office — Downers Grove (630) 964-8708 or Naperville (630) 360-2730 — or request an estimate.
A roof repair is priced by what failed, how much of the roof it affects, the pitch and height of the roof, and whether decking underneath is wet. A single-visit shingle, boot or flashing repair costs a fraction of a replacement; widespread hail damage is usually an insurance-covered replacement rather than a repair. Adept Construction gives a written, itemized estimate before any work starts and does not add charges afterward. Typical ranges by repair type — including sagging roof, leak and shingle repairs — are in our roof repair cost guide, or request an exact quote.

A roof repair is priced by what failed and how much of the roof is affected: a single-visit shingle, flashing or pipe-boot repair costs far less than a section replacement, and widespread hail damage usually becomes an insurance-covered replacement.

It depends on the municipality. Minor repairs generally do not need one in Naperville or Downers Grove. Naperville does not require a permit for asphalt shingle work that leaves the sheathing in place, and the Village of Downers Grove does not require one for residential shingle replacement. Adept Construction checks the local rule and pulls the permit when one is needed.
