Our Specialty Roofing Services in Lemont
Modified Bitumen Roofing
Modified bitumen is the workhorse for low-slope sections on Lemont’s older commercial buildings and residential additions. The torch-applied or self-adhering membranes stand up to the foot traffic of HVAC maintenance and the thermal movement that Lemont’s freeze-thaw cycles demand. We install modified bitumen systems from Atlas and Tamko with proper base sheets and cap sheets specified for northern Illinois temperature swings. On a recent job near the historic district, we recovered a 1980s-era modified roof that had cracked at the seams from years of valley frost-pocket cycling. The new two-ply system we laid should outlast the original by a decade.
Built-Up Roofing (BUR)
Built-up roofing remains relevant for Lemont’s flat-roofed commercial structures and some mid-century residential designs. The multiple layers of bitumen and reinforcing fabric create a redundant system that tolerates the ponding water that can accumulate when spring thaws hit frozen drains. We install BUR with gravel surfacing or reflective cap sheets, depending on the building’s cooling load and the owner’s preference. For limestone buildings in the village core, we pay particular attention to parapet detailing - the wall-to-roof transition on masonry construction requires counterflashing reglets cut into stone, not the simple termination bars used on frame buildings. This is specialized work that frame-construction contractors from Bolingbrook or Romeoville rarely encounter.
EPDM Roofing
EPDM rubber roofing suits Lemont’s low-slope applications where cost-efficiency and long service life matter. The single-ply membrane expands and contracts without the seam vulnerability of older systems, which matters in a climate where winter nights hit single digits and summer afternoons push ninety. We mechanically attach or fully adhere EPDM depending on wind exposure - and on Lemont’s bluff-top properties, that wind exposure calculation is real, not theoretical. Ballasted systems are generally not recommended for the west-facing slopes above the canal where uplift forces run higher than code minimums would suggest.
Solar Ready Roofing
Lemont homeowners adding solar arrays need roofing that will outlast the panels, not fail underneath them. Our solar-ready installations use elevated mounting systems that maintain membrane integrity and allow future access without disrupting the waterproofing layer. We coordinate with solar installers to specify attachment points during the roofing phase, which eliminates the leak risk of retrofitted penetrations. For the many 1980s-2000s colonials in Lemont entering their replacement cycle, this is the smart time to plan for solar - while the roof deck is exposed and the structure can be verified for load.
TPO Roofing
TPO’s white reflective surface helps reduce cooling loads on Lemont’s commercial buildings during humid July and August stretches. The heat-welded seams create a monolithic sheet that resists the algae and mold growth that shaded, damp conditions can encourage. We install TPO from GAF and CertainTeed with proper edge metal and fastening patterns rated for the wind speeds that the bluff-top elevations experience.
Green Roofing
Extensive green roof systems suit Lemont’s institutional and commercial buildings where stormwater management and thermal mass are priorities. The engineered growing medium and drainage layers add significant dead load, so we verify structural capacity before specifying - a step that matters on older masonry buildings where the original builders never anticipated saturated soil overhead. The payoff is reduced runoff into Lemont’s combined sewer system and extended membrane life from UV protection.

Trusted Brands We Service in Lemont
We are authorized installers for seven manufacturer lines: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Lemont customers, this means we stock the membranes, adhesives, and flashing components that local jobs require rather than ordering from a warehouse two states away and waiting a week. We specify Atlas and Tamko modified bitumen for low-slope work, and we match shingle replacements to existing IKO or CertainTeed installations when partial repairs make sense. The right material for your specific roof, not whatever happens to be on the truck. That’s the square deal.
Common Specialty Roofing Problems We See in Lemont Homes
- Blown ridge caps and lifted tabs on bluff-top streets. Contractors who work the west-facing slopes above the I&M Canal consistently find wind damage that wouldn’t occur a half-mile east in the valley. The elevation and open southwestern exposure channel prevailing winds in a way that makes enhanced wind-resistance shingles effectively mandatory up there.
- Freeze-thaw degradation in the valley frost pocket. Lemont’s position in the Des Plaines River valley amplifies freeze-thaw cycling relative to surrounding flat-terrain suburbs. Granule loss accelerates. Flashing seams open. We’ve seen ten-year-old shingles in Lemont look twenty, while identical installations in Plainfield hold up fine.
- Aluminum flashing corrosion on limestone buildings. Standard aluminum flashing corrodes when in contact with limestone mortar. The historic village core’s Niagara dolomite construction demands copper or lead alternatives, with masonry-compatible sealants that flex without pulling away from stone surfaces.
- Ice dam damage on steep, under-insulated bluff roofs. Heavy wet snowfalls add dead load to older, steeper-pitched homes. Inadequate attic insulation turns snow melt into recurring ice dams at the eaves, backing water under shingles and into wall cavities.

FAQs - Specialty Roofing in Lemont
Because the elevation and open exposure above the I&M Canal corridor channel prevailing winds that create measurably higher uplift than the surrounding flatlands. Standard fastening patterns and basic three-tab shingles are not engineered for this microclimate. We specify Class F wind-resistance rated shingles with enhanced fastening patterns on Lemont’s bluff-top properties, particularly west-facing slopes. Call (855) 641-3418 and we’ll assess your specific exposure.
Yes. Standard aluminum flashing corrodes in contact with limestone mortar, and standard sealants don’t adhere properly to masonry surfaces. Lemont’s historic village core, built with locally quarried Niagara dolomite limestone, requires copper or lead step flashing with masonry-compatible sealants and counterflashing reglets cut into the stone. Frame-construction contractors who don’t work limestone regularly miss this. We’ve repaired too many leaks caused by incompatible materials installed by out-of-area crews.
Multi-ply systems with redundant waterproofing layers outperform single-ply alternatives in severe freeze-thaw environments. For low-slope applications in Lemont, we typically recommend modified bitumen or built-up roofing with proper base flashing and drainage. On steep slopes, architectural shingles with enhanced adhesive strips and ice-and-water shield at the eaves handle the thermal cycling better than basic three-tab products. The key is proper attic ventilation to minimize the temperature differential that drives the cycle.
Most Lemont colonials from the 1980s-1990s are at or past the 20-30 year service life of their original 3-tab shingles. If you’re seeing widespread granule loss, curling, or lifted tabs, repairs become a band-aid on a failing system. We photograph and document the condition honestly. Sometimes targeted repairs with matching architectural shingles buy a few years. Often the math favors replacement, especially if you’re considering solar or if the decking shows moisture damage. We’ll show you the photos and explain both paths.
Yes, if the attic insulation and ventilation are inadequate. Lemont’s bluff-top homes with steep pitches collect heavy snow loads that melt from below, refreeze at the eaves, and back water under shingles. We install ice-and-water shield membrane extending at least 24 inches inside the exterior wall line on all Lemont replacements, and we evaluate attic airflow as part of every job. The membrane is the backup; proper ventilation is the cure. Call (855) 641-3418 for a free inspection.
On a limestone-and-brick home along the west-facing bluffs above the I&M Canal, we replaced a set of original 1990s 3-tab shingles that had lifted tabs from wind uplift. We installed Owens Corning Duration Flex with enhanced wind resistance (Class F) and custom copper step flashing integrated with the masonry walls. The homeowner told us the roof held solid through the next windstorm that had damaged three neighboring properties.
