We’ve been climbing Ashburn roofs since 1984. We know the brick bungalows along Kedvale and the ranches near 79th Street. We know that your low-slope rear addition was probably patched three times before you bought the place, and that the flashing where brick meets roofline is the first thing to let go. Our Specialty Roofing team doesn’t guess. We photograph what we find, explain it plain, and give you a written number that doesn’t change.

Our technicians are background-checked and uniformed. They document every inspection with photos from your actual roof - not a scary speech in your driveway. The estimate we leave is the invoice you pay. A square deal: the price we quote is the price you pay.
Our Specialty Roofing Services in Ashburn
Built-Up Roofing
Built-up roofing, or BUR, is the tar-and-gravel system many Ashburn bungalow owners inherited. Here’s the hard truth: on a 1950s brick bungalow on Kedvale Avenue, our crew discovered three layers of built-up roofing over rotted OSB on the low-slope rear section; we tore it all off, replaced the decking, and installed a new EPDM membrane with proper step flashing at the brick wall, restoring a watertight system. That scenario repeats across Ashburn. Multiple generations of patchwork trap moisture and rot decking - a legacy of pre-2000s habits that Chicago’s modern code now prohibits. When we find sound decking beneath one layer, we’ll tell you. When we find mush, we don’t cover it up. A full BUR tear-off in Ashburn typically runs $10,000-$16,000.

EPDM Roofing
EPDM, the black rubber membrane, is what we install most often on Ashburn’s low-slope rear additions. It flexes with our extreme temperature swings - 0°F to 95°F+ - without the cracking that destroys modified bitumen over time. On Ashburn’s postwar bungalows, proper installation means extending the membrane up the brick parapet wall and securing it with termination bars, not just glue at the edge. EPDM replacement in Ashburn averages $8,500-$14,000 for a typical rear addition. Spot repairs run $400-$1,200 if the membrane is sound and the leak is localized.

Modified Bitumen
Modified bitumen serves Ashburn homeowners who want the look of built-up roofing with faster installation. The torch-down or peel-and-stick sheets work well on low-slope sections, but Chicago’s freeze-thaw cycling is hard on them. Ice dams form where the bungalow’s pitched front meets the flat rear, and the constant expansion and contraction open seams. We install modified bitumen with proper base sheets and edge metal, and we always inspect the brick-to-roofline flashing because that’s where Ashburn failures start. Expect $9,000-$15,000 for a full modified bitumen system in this neighborhood.

Solar Ready Roofing
Ashburn’s solid-brick bungalows have the structural mass to support solar arrays, but the roof has to be ready. Solar ready roofing means decking that can handle point loads, penetration flashing that won’t leak in year eight, and a membrane life that outlasts the panel warranty. We coordinate with your solar installer, or we can recommend ones we’ve worked with on Chicago’s southwest side. Most Ashburn solar-ready low-slope prep jobs run $11,000-$17,000 before panels.

Trusted Brands We Service in Ashburn
We install what works, not what pads margin. Ridgeline Roofing Co. is an authorized installer for seven manufacturer lines, and for Ashburn’s specialty roofing needs we draw most often from Atlas, Tamko, and Boral. Atlas supplies the TPO and modified bitumen we trust on low-slope sections. Tamko’s underlayments and edge metals hold up to Ashburn’s temperature swings. Boral’s clay and concrete tiles suit the occasional Ashburn homeowner who wants a green roof system’s structural base. We stock common membrane widths and flashing profiles locally, so we’re not waiting on freight when your roof is open.
Common Specialty Roofing Problems We See in Ashburn Homes
- Layered patchwork on low-slope rear additions. Ashburn’s postwar bungalows often carry two or three generations of built-up roofing over progressively rotted decking. Chicago code now prohibits this, but the legacy remains. We tear it all out and start clean.
- Flashing failure at brick-to-roofline interfaces. The parapet walls and chimney stacks on Ashburn’s solid-brick homes demand step flashing and counter flashing installed precisely. Freeze-thaw cycling opens gaps where caulk and tar can’t hold.
- Membrane cracking from extreme temperature swings. Ashburn’s southwest-side location spares it the heaviest lake-effect snow, but winter nor’easters still drive wind-blown ice under aging shingles. EPDM and modified bitumen on low-pitch sections crack where ice dams form repeatedly.
- Rotted OSB beneath apparently sound surfaces. Multiple generations of tar-and-gravel patchwork trap moisture against decking. The top layer looks fine. The wood beneath is mush. We photograph it so you see what we see.

FAQs - Specialty Roofing in Ashburn
No, but it usually is. If we find one sound layer over solid decking, a recover might work. In Ashburn, we more often find three layers over rotted OSB - a legacy of pre-2000s patching that Chicago code now prohibits. We photograph the decking and show you. Call (855) 641-3418 and we’ll give you a straight answer after inspection.
Freeze-thaw cycling at the brick-to-roofline interface opens gaps that caulk can’t seal. Ashburn’s parapet walls and chimney stacks on 1940s-1960s bungalows weren’t built with modern step-flashing details. We install proper counter-flashing reglets cut into mortar joints - the permanent fix, not another tube of sealant. Call for an inspection and we’ll show you exactly where the water’s getting in.
Yes, if the membrane is sound and the leak is from a puncture or seam failure. A proper EPDM patch with primer and seam tape runs $400-$1,200 in Ashburn. If the membrane is brittle, chalking, or pulling from the walls, patching wastes money. We’ll tell you which situation you’re in. Call (855) 641-3418 for a free inspection.
Yes. Ashburn is ZIP 60652, a Chicago neighborhood, not a standalone municipality. All roofing work falls under Chicago Department of Buildings permits and inspections - a regulatory layer that neighboring Cook County suburbs like Oak Lawn do not require. We pull permits as part of every job. You don’t handle the paperwork.
It is, with the right system. Chicago’s temperature range demands drainage layers that handle both freeze-thaw and summer heat. Ashburn’s solid-brick bungalows have the structural load capacity for an extensive green roof. We install proper root barriers, drainage mats, and drought-tolerant sedum varieties that survive our winters. Expect $18,000-$28,000 for a full system. Call (855) 641-3418 to discuss whether your roof structure and sun exposure suit it.
