Fast, Reliable Specialty Roofing Across Westmont
Specialty roofing in Westmont, IL typically runs $8,500-$22,000 depending on material and scope, with most inspections scheduled within 24 hours and work starting within a week. If you’re calling from a 1960s ranch near South Williams Street or a split-level off Ogden Avenue, you’re probably dealing with the same problems we’ve handled on hundreds of Westmont roofs: heat-trapped attics, layered shingles hiding rot, and low-slope transitions that leak quietly for years.
We’ve been driving to Westmont since 1984, long enough to know which east-side blocks still carry original postwar roofing and which west-side developments need storm-hardened materials after the last hail cell rolled through. Our Specialty Roofing team answers the phone live, day or night, at (855) 641-3418. No voicemail. No callback window. A real person who can get a technician to your Westmont home today.

Our Specialty Roofing Services in Westmont
Solar Ready Roofing
Westmont’s flat DuPage County plain gets unobstructed southern exposure, making it a strong candidate for future solar installation even if you’re not ready today. Solar Ready Roofing installs reinforced decking, proper flashing, and electrical conduit paths now so you don’t tear off a new roof later. We use Owens Corning and Atlas systems rated for panel loads and wind uplift, critical on Westmont’s open prairie where northwest winds hit without buffer. The 1960s ranches with unvented soffits we see near Cass Avenue particularly benefit, since solar-ready installation forces proper ventilation upgrades that solve the heat-trap problem at its source.
TPO Roofing
TPO single-ply membrane is our go-to for Westmont’s chronic leak points: low-slope garage additions, enclosed porches, and split-level transitions where shingles fail within seasons. The white reflective surface drops surface temperature 30-40 degrees versus dark shingles, a real advantage on west-facing garage roofs that bake July through September. We install fully adhered and mechanically attached TPO systems from GAF and CertainTeed with heat-welded seams that outlast tape or glue methods. For the ranch on South Williams Street we mentioned earlier, TPO was the right call on the garage transition after we stripped three layers of failed shingles and found compromised decking beneath.
EPDM Roofing
EPDM rubber membrane handles Westmont’s freeze-thaw cycling better than almost any material, flexing through the temperature swings that split lesser products on low-slope applications. We install black and white EPDM from authorized manufacturer lines, ballasted or fully adhered depending on your structure’s wind exposure. The material’s 20-30 year lifespan makes sense for Westmont homeowners who intend to stay put, which describes most of our callers from the older neighborhoods east of Williams Street.
Modified Bitumen
Modified bitumen brings multi-ply redundancy to Westmont’s problem transitions, torch-applied or cold-adhered in two or three layers that seal even if one fails. We use it where TPO or EPDM aren’t practical, steep enough for water shedding but too low for standard shingles. DuPage County code requires full tear-off before new installation on homes with multiple existing layers, and modified bitumen lets us build proper slope with tapered insulation where the original framing settled flat. This matters on Westmont’s 1950s-1970s stock, where garage slabs heaved over decades and created pooling that destroys standard roofing.

Common Specialty Roofing Problems We See in Westmont Homes
- Closed, unvented soffit systems on 1960s ranches trap heat, accelerating granule loss and shingle failure in 12-15 years instead of 25. We’ve found this on nearly every block in older east-side neighborhoods, where original construction omitted ridge vents entirely and homeowners never knew to ask.
- Multiple shingle layers on low-pitch roofs hide deteriorated decking and ice dam damage, especially on east-side homes with legacy roofing. DuPage County code requires full tear-off before any new installation when two or more layers exist, but many Westmont roofs carry three, compounding weight and masking rot.
- Low-slope garage-to-house transitions on split-levels are chronic leak points, often undetected until interior damage appears. The modest pitch and enclosed soffits on Westmont’s dominant housing type create perfect conditions for slow, hidden water intrusion that destroys insulation and framing.
- Hail damage concentrated on west and southwest exposures goes unreported because homeowners mistake it for normal aging. DuPage County’s hail claim volume ranks among Illinois’ highest, and Westmont’s flat terrain offers no natural protection from storm cells tracking northeast.
Pricing for Specialty Roofing in Westmont, IL
A typical TPO installation on a Westmont garage transition runs $4,200-$7,800 depending on square footage and decking condition.

FAQs - Specialty Roofing in Westmont
A new roof alone will not fix the heat buildup; you need proper intake and exhaust ventilation installed as part of the project. We routinely add continuous soffit vents and ridge vents during Westmont tear-offs, converting closed attic systems to passive airflow that drops peak temperatures 40-60 degrees. This extends shingle life from 12-15 years back toward their 25-year rating. Call (855) 641-3418 and we’ll show you exactly what your soffit situation looks like from the roof.
No, DuPage County code prohibits overlay when two or more shingle layers already exist, and three layers exceed structural load limits for most 1960s-1970s framing. We perform full tear-offs on nearly every Westmont job we take, which lets us inspect and replace rotted decking hidden beneath those layers. The extra day of work costs more upfront than an illegal overlay, but it’s the only way to meet code and know what’s actually protecting your home. Call (855) 641-3418 for a tear-off estimate that includes decking replacement if needed.
Your shingles are almost certainly failing from trapped attic heat caused by unvented soffits, the most common premature failure pattern we see in Westmont’s 1960s ranches. The granules bake off, the asphalt dries and cracks, and the roof looks ancient while still on paper under warranty. We’ve replaced 12-year-old shingles on east-side blocks where every neighboring ranch shows the same pattern. Proper ventilation during replacement is the only fix. Call (855) 641-3418 and we’ll document the granule loss and soffit condition with photos from your roof.
Yes, TPO is often the best choice for Westmont’s low-slope garage transitions and enclosed porches, where shingles can’t shed water fast enough and ice dams collect at the eaves. The white reflective surface handles summer heat, and heat-welded seams survive the freeze-thaw cycling that opens glued joints. We recently installed TPO on a 1965 ranch’s garage transition after stripping three failed shingle layers and finding rotted decking beneath. Call (855) 641-3418 to see if your slope qualifies and get a range for your specific footprint.
You don’t need it, but for Westmont’s unobstructed southern exposure and strong sun hours, solar-ready installation costs roughly 8-12% more now and saves a full tear-off later when panels make financial sense. The reinforced decking and pre-run conduit also force proper ventilation upgrades that solve the heat-trap problems common in local 1960s ranches. Many Westmont homeowners who call us for premature shingle failure end up glad they added solar-ready spec once they understand how the ventilation improvements extend roof life regardless of panels. Call (855) 641-3418 and we’ll walk through the numbers both ways.
