Lemont is a Cook County village of about 17,629 people that reads like two different towns stitched together by the Des Plaines River valley. Downtown sits on a hillside above the river, the old Illinois and Michigan Canal, and the Chicago Sanitary and Ship Canal, built from locally quarried dolomite limestone that 19th century workers nicknamed “Athens marble.” Thirty eight of those limestone buildings anchor a downtown commercial district added to the National Register of Historic Places in 2016, some sitting under rooflines that predate 1900. Climb out of the valley in either direction and the housing stock changes fast: Lemont’s population jumped from 7,348 in 1990 to 13,098 by 2000, and most of what got built to house that growth sits in newer subdivisions on the south and west edges of the village.
Here is how SkyeVantage coordinates a replacement in Lemont. You pick the shingle. SkyeVantage supplies it at wholesale cost, along with synthetic underlayment, a self-adhering ice and water membrane run from the eave to 24 inches inside the interior wall line per Illinois code, drip edge, ridge cap, and a balanced intake-and-exhaust ventilation setup. That setup gets scoped differently depending on where your roof sits: a steep, bluff-side lot near downtown often means tighter street access and more careful dumpster and material staging, while a roof in one of Lemont’s newer subdivisions is usually a straightforward first-cycle tear-off. A Preferred Roofing Network crew handles the tear-off and the install to lifetime-warranty spec. Axium inspects the finished work. SkyeVantage pulls the permit and handles the coordination end to end.
One flat fee covers the coordination, the labor, the materials setup, and the dumpster. That’s how you get everything at cost. You see the receipt. We’re not here to sell you a roof. We’re here to service the home.
Lemont sits in a humid continental, hot-summer climate (Köppen Dfa). NOAA 1991-2020 normals for the Chicago metro (O’Hare) frame what your roof handles every year.
- Annual snowfall averages 38.4 inches. That is real snow load and meltwater on every slope, and it runs downhill fast on Lemont’s bluff-side roofs above the Des Plaines River valley.
- January averages 25.2°F (high 31.6, low 18.8). Freeze-thaw cycling and ice damming punish eaves, which is exactly why the ice and water membrane runs 24 inches inside the wall line.
- July averages 75.4°F (high 84.5, low 66.4). Summer UV and heat drive granule loss over time, so full-system ventilation protects shingle life.
- Annual precipitation averages 37.86 inches. Water management is the whole game here: flashing, valleys, and step flashing matter on downtown Lemont’s pre-1900 limestone-era rooflines just as much as on a newer subdivision roof.
- Peak wind and hail season runs roughly April through August. Northern Illinois averages 10 to 15 days a year with 1-inch-plus hail, and an August 11, 2026 derecho brought widespread wind damage and tornadoes across northern Illinois.
Asphalt shingle systems only. Homeowners pick the brand. SkyeVantage supplies it at wholesale cost. A Preferred Roofing Network crew certified for that product handles the install to lifetime-warranty spec.
- Class 4 impact-resistant (wind and hail): GAF Timberline AS II, Owens Corning Duration FLEX. Impact-rated shingles may qualify for an Illinois homeowners insurance premium discount, so ask your carrier.
- Architectural (regional standard): GAF Timberline HDZ, Owens Corning Duration, CertainTeed Landmark, Atlas Pinnacle Pristine, Tamko Heritage.
- Designer (premium): Owens Corning Duration Designer (Onyx Black, Pacific Wave), CertainTeed Presidential Shake, GAF Grand Sequoia. On a roof visible from the street inside Lemont’s downtown Historic District, a Designer profile like Presidential Shake can read closer to the building’s original limestone-era character without leaving asphalt shingle systems, and SkyeVantage checks Certificate of Appropriateness requirements before that material gets ordered.
