Park Ridge Roof Replacement: What Bungalows and Colonials Actually Need (2026)
Park Ridge's housing stock is older than most Chicagoland suburbs. Here's what bungalows and colonials actually need on the roof — and what surprises usually show up under the shingles.
Park Ridge's housing stock is older than most Chicagoland suburbs
Park Ridge has a meaningful share of homes built between 1900 and 1940 — Chicago bungalows along the older grid streets, English Tudor and Cape Cod style homes through the central neighborhoods, and pre-war colonial revivals in the more established areas. The 1950s through 1970s added another wave of colonials, raised ranches, and split-levels through the post-war expansion. That mix matters for roofing because pre-war homes typically have framing, ventilation, and deck conditions that look nothing like a modern subdivision house. A roofer who only works on 1990s-2010s builds will be surprised by what's under a Park Ridge bungalow's shingles.
1920s bungalows: what's actually under there
On a typical 1920s Chicago-style bungalow in Park Ridge, the original deck is often 1x6 or 1x8 skip-sheathing — boards spaced 1-2 inches apart, originally designed for wood shake roofing and later just covered when the home was re-roofed in asphalt. Skip-sheathing is structurally fine but requires either solid sheathing overlay (typical modern approach, adds 1/2-inch plywood over the existing deck) or specific specialty underlayment and shingle compatibility considerations. Many bungalows also have minimal or no ridge venting — original design relied on roof-mounted box vents or just gable vents — and the existing attic ventilation rarely meets modern code or modern shingle warranty requirements. Plan for ventilation correction as part of the project, not as a surprise after the fact.
1950s-1970s colonials: different problems
Post-war colonials in Park Ridge typically have solid 1/2-inch plywood or OSB decking, but after 50-70 years and multiple roof replacements that deck has often been compromised — moisture damage from old ice dam events, repeated nail holes in the same areas, sections soft from leaks that were patched rather than properly repaired. The original ventilation was often turbine vents or gable-only ventilation that wasn't ideal even when the home was new. The flashings — particularly at chimneys and any room additions — have often been patched and re-patched over decades, with each layer hiding the failures of the one underneath. A real estimate on a colonial-era Park Ridge home includes a deck condition allowance and a chimney/wall flashing rebuild scope rather than 'flash as needed' language.
Decking surprises (and how to budget for them)
When the existing roof comes off a Park Ridge home, deck replacement is more common than on newer homes. Sections of soft decking from old leaks, compromised areas around penetrations, and pre-war skip-sheathing that needs overlay all add cost — typically $80-$150 per 4x8 sheet of replacement plywood, including labor. A bid that doesn't include a deck allowance is often a low bid that's going to come back with a change order on day one. We typically include a deck allowance — usually 2-4 sheets for a normal-looking older home, more if the home shows signs of repeated leaks — and refund the difference if less is needed. Ask each bidder how they handle deck replacement and what the per-sheet add-on is.
Material specifications that work for the architecture
For a Park Ridge bungalow or pre-war colonial, a quality architectural shingle is usually the right call — typically GAF Timberline HDZ in Charcoal, Slate, or Weathered Wood; CertainTeed Landmark in Heather Blend or Moire Black; or Owens Corning Duration in Driftwood. The dark, weathered-tone colors read appropriately on the architecture; the loud orange-brown 'autumn blend' shingles that show up on tract suburbs don't. For larger 1920s English Tudor or Cape Cod style homes, cedar shake or synthetic slate is occasionally the right specification when the architecture and budget support it. See best roof colors for Chicago suburbs for the color framework.
Park Ridge permit and code notes
Park Ridge requires permits for roof replacements and enforces a 2-layer maximum (a second layer over existing is allowed only when the underlying deck and structural conditions are good — and even then, full tear-off is generally the right answer on older homes). Permit timing is usually 1-2 weeks. Park Ridge inspectors are reasonable but pay attention to ice-and-water coverage and ridge venting, so plan to have those specified correctly. Historic Park Ridge has limited architectural review on certain blocks; verify before committing to non-asphalt materials.
What it costs
A roof replacement on a typical Park Ridge bungalow (1,200-1,700 square feet, single roof plane) generally runs $14,000-$22,000 with a quality architectural shingle and proper deck/ventilation work. Older colonials and Cape Cods (1,800-2,800 square feet, more complex rooflines) run $20,000-$35,000. Larger pre-war homes with multiple dormers, slate replacement, or cedar shake are $35,000-$75,000+ depending on material and complexity. We quote total project cost after inspecting the home, never per-square-foot.
