We’ve been driving to Westmont since 1984, long enough to know the difference between a solid roof on a 1965 ranch near Cass Avenue and one that’s been patched past saving. The village’s postwar housing stock tells a consistent story: two or three layers of asphalt shingles, unvented soffits that baked the decking from below, and garage transitions that leak every spring thaw. Our Roof Replacement & Installation team doesn’t guess at what’s under your shingles. We photograph every square foot, quote the full scope upfront, and stand behind the work with our written 90-Day Done Right Promise. No paperwork runaround. If it’s not right, we make it right.
Why Ridgeline Roofing Co. of Chicago Is Westmont’s Preferred Roof Replacement & Installation Company
Westmont homeowners remember contractors who disappeared after the check cleared. We’re still here because we never left. Pete Callahan has led Ridgeline Roofing Co. since the company’s founding in 1984, building a business on repeat customers and neighbor referrals rather than storm-chasing trucks with out-of-state plates.
Our reputation in Westmont rests on specifics. We know DuPage County enforces a full tear-off when two layers exist, which covers most of the village’s older housing stock. We know the east-side neighborhoods near Westmont High School where unvented 1960s ranches cluster, and we know how to price the ridge vent conversion those homes need. Background-checked, uniformed technicians handle every inspection, and every call comes through to a live person - 24 hours a day, including the Sunday night when your garage starts dripping.
Response time to Westmont averages same-day for emergencies and within 48 hours for standard inspections. We keep Owens Corning and CertainTeed materials stocked for common Westmont profiles, which means less waiting once you approve the scope.
Our Roof Replacement & Installation Services in Westmont
Full Roof Replacement
Most Westmont homes need this, not a repair. The village’s postwar building boom left thousands of ranches and split-levels now carrying two or three shingle layers - and DuPage County code requires full tear-off before any new installation when that second layer exists. We strip to decking, replace what rot we find (and on unvented soffit homes, we usually find some), install proper underlayment, and finish with a roof built to current standards. On a sprawling split-level in the East Hills subdivision, we tore off three layers of weathered asphalt and found rotted decking under the unvented, boxed soffits. We installed Owens Corning Duration Storm shingles with a ridge vent system and sealed the low-slope garage transition with modified bitumen, solving the chronic leaks that had plagued the home for years. Full replacement on a typical Westmont home runs $12,500-$22,000.
Asphalt Shingles
The practical choice for Westmont’s modest-pitch ranches. We install CertainTeed Landmark and Owens Corning Duration lines rated for the hail and wind exposure that comes with life on the open DuPage plain. Standard architectural shingles run $3.50-$5.50 per square foot installed; impact-resistant Class 4 products add roughly 20% but often earn insurance discounts. For west-side homes catching unobstructed northwest winds, we recommend starter strips and six-nail patterns on the rake edges.
Flat Roofing
Westmont’s ranch and split-level floor plans commonly include low-slope garage roofs or rear additions that were originally covered with rolled asphalt or early modified bitumen. These areas fail first - ponding water, poor original flashing, and freeze-thaw cycling open seams within 10-15 years. We replace with properly sloped tapered insulation where needed, then install either TPO or multi-ply modified bitumen systems. Flat sections on a typical Westmont home add $2,800-$5,500 to the total project.
Metal Roofing
Standing seam metal suits Westmont homeowners planning to stay for decades. The upfront cost runs roughly double asphalt - $22,000-$38,000 for a typical ranch - but the lifespan extends past 50 years with minimal maintenance. Metal sheds hail better than shingles, and its slick surface reduces ice dam formation on those low-pitch eaves. We install Atlas and IKO metal product lines with concealed fasteners that won’t back out in thermal expansion.
New Construction
Westmont’s infill lots and teardown rebuilds in areas like the newer sections near 63rd Street require roofing integrated from the framing up. We coordinate with builders on ventilation design, avoiding the boxed-soffit mistakes that plague the village’s older stock. New construction roofing runs $4.50-$8.00 per square foot depending on material and complexity.

Trusted Brands We Service in Westmont
We are authorized installers for seven manufacturer lines, and we stock the ones that matter for Westmont’s conditions. Owens Corning Duration Storm and CertainTeed Landmark IR both carry Class 4 impact ratings - relevant here, where DuPage County consistently ranks among Illinois’ highest counties for hail claim volume. IKO Cambridge architectural shingles offer solid performance at moderate cost for homeowners replacing a roof once before selling. Atlas StormMaster Slate provides a dimensional look with hail resistance for the village’s higher-end ranches near the Hinsdale border. We don’t substitute materials mid-job. The brand on your estimate is the brand on your roof.
Common Roof Replacement & Installation Problems We See in Westmont Homes
- Unvented soffits baking shingles from below. Westmont’s 1960s ranches frequently have fully boxed, unvented soffits with no ridge vent - a closed attic system that traps summer heat and accelerates granule loss, causing 25-year-rated shingles to fail in 12-15 years. Local roofers encounter this premature failure pattern on nearly every block in the older east-side neighborhoods.
- Hidden deck rot under multiple shingle layers. Two or three layers of asphalt trap moisture against plywood or plank decking, especially where unvented attics create condensation cycles. We find soft decking on roughly 60% of Westmont tear-offs, and we replace it before the new roof goes on - no surprises, no change orders.
- Low-slope garage transitions leaking every spring. The attached garages common on Westmont ranches and split-levels create a pitch change that original builders often flashed inadequately. Ponding water and freeze-thaw cycling open seams; by March, we’re fielding calls from homeowners who’ve placed buckets under the same spot for three years running.
- Ice dam damage on wind-exposed eaves. Westmont sits on the open, flat DuPage County plain with minimal natural windbreaks. Northwest winds drive snow against low eaves, where freeze-thaw cycling builds ice dams that lift shingles and saturate underlayment. Proper ice-and-water shield extending past the interior wall line prevents this, but many original roofs lacked it.

FAQs - Roof Replacement & Installation in Westmont
Yes, and not just for shingle warranty coverage. Without exhaust ventilation, your attic becomes a convection oven in July, baking shingles from below while summer sun attacks from above. We install ridge vent on nearly every Westmont ranch we re-roof, paired with properly cut soffit intakes where the original boxing allows. The conversion adds $1,200-$2,400 but extends shingle life by a decade or more. Call (855) 641-3418 and we’ll assess your specific soffit configuration during the free inspection.
No. DuPage County code prohibits more than two layers, and most Westmont homes already have two. A third layer would add dangerous weight to structures never engineered for it, mask deck rot until it collapses, and void manufacturer warranties. The “savings” evaporate when the roof fails prematurely and insurance denies the claim for code violation. We quote full tear-offs only - done right, with no shortcuts that cost more later.
Because the original builder likely used standard asphalt shingles on a slope below 4:12, where shingles aren’t rated, and flashed the transition to the main roof with caulk instead of proper step flashing. Spring thaw pools on the low slope, finds the seam, and runs inside. We replace these sections with modified bitumen or TPO systems rated for flat application, then detail the transition with ice-and-water shield and metal flashing. The bucket stays in the garage.
DuPage County consistently ranks among Illinois’ highest counties for hail claim volume, and Westmont’s position on the open plain makes it a repeat target for severe cells tracking northeast. Most Westmont homeowners replace for age and ventilation failure rather than single catastrophic hail events, but we handle 20-30 insurance-driven full replacements annually after major spring and summer storms. If your neighbors are getting new roofs after a storm, call us for a free inspection - damage isn’t always visible from the ground.
They are, for the right homeowner. Metal sheds hail better than asphalt, reduces ice dam formation on low-pitch eaves, and lasts 50+ years. The upfront cost runs roughly double asphalt, so it pencils best for homeowners planning to stay 15 years or more. We install Atlas and IKO concealed-fastener systems that won’t telegraph noise in rain and won’t back out from thermal expansion. Not every Westmont ranch needs metal, but for homeowners who want to do it once, it’s a square deal.
