Mount Greenwood sits at the far southwest edge of Chicago, zip code 60655, bordered by 111th Street to the north and the Calumet River valley to the south. We’ve been driving these streets since 1984, and we know the difference between a Mount Greenwood bungalow on South Homan Avenue and a postwar ranch near St. Xavier University. That local knowledge matters when your roof is leaking at 2 a.m. and you need someone who understands Chicago Building Code enforcement, not a suburban contractor who thinks Mount Greenwood is Oak Lawn.
Why Ridgeline Roofing Co. of Chicago Is Mount Greenwood’s Preferred Roof Replacement & Installation Company
We’ve replaced and installed roofs on hundreds of Mount Greenwood homes over four decades. Our crews have worked on the low-pitched hip roofs of 1920s bungalows near Mount Greenwood Park and the steeper gables of 1960s ranches along West 107th Street. That depth of local experience means we spot problems before they become emergencies: the hidden third layer of shingles, the rotted sheathing beneath a 1970s overlay, the attic ventilation that was never updated from 1935.
Mount Greenwood homeowners call us because we answer the phone. A live person, 24 hours a day, seven days a week. No voicemail tree, no “leave a message and we’ll call back tomorrow.” When ice dams back up into your living room during a January freeze-thaw cycle, you need a voice on the line, not a callback window.
Our 90-Day Done Right Promise applies to every Mount Greenwood job. Written guarantee. No paperwork to file, no argument about whether the leak is “in scope.” If it’s not right, we come back and make it right. We’ve operated this way since 1984, and we’re not changing.
Every technician who steps onto your property is background-checked and uniformed. We photograph every roof inspection from the actual surface, not the driveway. The photos go to you, with plain-language explanations of what we found and what it means for your home.
Our Roof Replacement & Installation Services in Mount Greenwood
Full Roof Replacement
Most Mount Greenwood homes need a full tear-off, not an overlay. Chicago code prohibits covering more than one existing layer of shingles, and many of these bungalows already carry two or three. We recently replaced a 1930s bungalow roof on South Kedzie Avenue. The original three-ply built-up roof had been overlain twice, hiding rotted sheathing. We performed a full tear-off, installed ice-and-water shield on eaves and valleys, and used GAF Timberline HDZ shingles with proper attic ventilation to prevent future ice dam issues. A square deal: the price we quote is the price you pay.
Asphalt Shingles
For the typical Mount Greenwood bungalow or two-flat, architectural asphalt shingles remain the practical choice. We install GAF, CertainTeed, and Owens Corning lines with full manufacturer warranty registration. The key on these low-pitched roofs is underlayment quality and eave protection, not just shingle brand. Summer attic temperatures in under-ventilated Mount Greenwood bungalows routinely exceed 150°F, baking shingles from below. We address ventilation as part of every shingle replacement, not as an upsell.
Flat Roofing
The shallow-pitched sections common on Mount Greenwood bungalows, porch roofs, and garage additions demand specialized flat or low-slope systems. Standard shingles installed on pitches below 4/12 without proper underlayment leak within the first year. We use modified bitumen, TPO, or built-up roofing where appropriate, with ice-and-water shield extending well beyond code minimums. Chicago’s 30+ annual freeze-thaw cycles punish marginal flat roof work.
Metal Roofing
Metal roofing makes sense for some Mount Greenwood homeowners, particularly on postwar ranches with adequate structural capacity and steeper pitches. The upfront cost runs higher, but the lifespan exceeds asphalt in freeze-thaw conditions. We install standing seam and metal shingle systems from Atlas and Tamko, properly flashed at valleys and penetrations. Not every Mount Greenwood roof can handle the weight or the aesthetic; we’ll tell you honestly if metal isn’t right for your home.

Common Roof Replacement & Installation Problems We See in Mount Greenwood Homes
- Multiple hidden shingle layers triggering permit failures. Many Mount Greenwood bungalows still carry a third nail strip of original or early-replacement shingles beneath two subsequent re-roofs. Chicago code now mandates full tear-off before re-roofing, and DOB inspectors specifically flag this. Homeowners who hired cut-rate contractors assuming an overlay would pass have faced stop-work orders and lien exposure.
- Ice dam damage at eaves and valleys. Chicago’s hard freeze-thaw cycles, often 30+ events per winter, are especially punishing on Mount Greenwood’s shallow-pitched roofs. Heat loss through poorly insulated 1930s-1940s attics accelerates ice formation. Without ice-and-water shield extending properly up the roof plane, water backs up under shingles and into wall cavities.
- Attic ventilation deficits cooking shingles from below. Those same under-ventilated bungalows see summer attic temperatures above 150°F. Asphalt shingles rated for 25-30 years under normal conditions degrade in 15-18 years in these environments. We install ridge vents, soffit vents, or powered ventilation as needed, not as an afterthought.
- Low-slope sections treated with standard shingles. Porch roofs, garage roofs, and rear additions on Mount Greenwood homes often sit at 3/12 or 4/12 pitch. Standard asphalt shingles on these pitches without adequate underlayment leak predictably at valleys and penetrations. We specify low-slope materials where the geometry demands it.

FAQs - Roof Replacement & Installation in Mount Greenwood
Yes. Although Mount Greenwood feels suburban, it is within Chicago city limits (60655), and every roof replacement requires a Chicago Department of Buildings permit and compliance with the Chicago Building Code. This is not optional, and unpermitted work can result in failed inspections, stop-work orders, and complications when you sell your home. We handle permit acquisition as part of every Mount Greenwood job. Call (855) 641-3418 and we’ll walk you through the timeline.
No. Chicago Building Code prohibits installing new shingles over more than one existing layer, and many Mount Greenwood bungalows already exceed this. DOB inspectors specifically check for hidden layers during permit inspections, and we’ve seen homeowners burned by contractors who promised a quick overlay. A full tear-off is required, and it’s what your roof needs anyway to address sheathing rot and ventilation deficits. We price tear-offs honestly, with no surprise charges when we find that third layer. Call (855) 641-3418 for an inspection and written estimate.
Ice dams form when heat loss through your attic melts snow from below, and the water refreezes at the cold eaves. Mount Greenwood’s shallow-pitched bungalow roofs, built with minimal insulation and ventilation in the 1930s-1950s, are especially prone to this. Chicago’s 30+ annual freeze-thaw cycles make it worse. The fix is a combination of proper attic insulation, ventilation, and ice-and-water shield extending well up the roof plane, not just at the gutter line. We address all three as part of a proper replacement. Call (855) 641-3418 to schedule an inspection.
Quality architectural asphalt shingles from GAF, CertainTeed, or Owens Corning, properly installed with ice-and-water shield and adequate ventilation, perform well for most Mount Greenwood homes. Metal roofing excels on steeper pitches but costs significantly more. Standard three-tab shingles are a false economy in this climate. The material matters less than the installation quality: full tear-off, proper underlayment, and ventilation that accounts for your specific attic conditions. We’ll recommend what fits your roof geometry and budget. Call (855) 641-3418 for a free second opinion on any written estimate.
Yes. Several of our manufacturer lines, including CertainTeed and Boral, offer synthetic slate and tile products that replicate the original aesthetic without the structural weight or maintenance burden. Many Mount Greenwood bungalows were built with slate or clay tile that was later replaced with asphalt; we can restore the historic appearance while meeting modern code requirements. We’ll bring samples to your inspection so you can see the match against your existing masonry and trim. Call (855) 641-3418 to schedule.
