Duncanville is a Best Southwest city of brick ranch homes. Most neighborhoods went up in the 1960s and 1970s along US 67 and I-20, and those houses are now on a second or third roof. It is one of our shorter trips south, about 30 minutes (18 miles) from Irving. Here, age shows up below the shingles: decking that has carried multiple roofs, attic venting that was never upgraded and rooflines that have started to sag.
Second- and Third-Generation Roofs in Best Southwest Ranch Neighborhoods
Each re-roof adds nail holes to the decking, and decades of small leaks leave soft spots around chimneys and vents. Some houses still carry two layers of shingles from an overlay. Until those layers come off, nobody can say for sure what the next roof will be nailed into.

From the street, a wavy roofline often means decking sagging between rafters. Our roof decking replacement work fixes that before new shingles go down.
The weather side of the profile is familiar but hard on roofs this old. Spring hail crosses the Best Southwest cities most years, and after decades of sun the shingles on older Duncanville roofs have lost the flexibility to take a hit without cracking. The April 3, 2012 outbreak struck Lancaster, just past DeSoto, so tornado warnings here are not hypothetical. Live oaks, elms and pecans line many streets and have had sixty years to grow over the rooflines. Those low-pitch roofs also have wide eaves, so water lingers at the gutter line, where old fascia and the first row of decking soften first. Inside, many attics have had insulation blown in over the years without baffles, which buries the soffit openings and traps heat.

Are Old Turbine Vents Hurting Your Duncanville Roof?
Often, yes. Many 1960s–70s homes here rely on turbine vents added decades ago, with soffits painted shut or blocked by insulation. A hot attic bakes shingles from below. While the old shingles are off, we can correct roof ventilation with balanced intake and exhaust.

Roof Replacement and Hail Repair Along US 67 and I-20
In Duncanville, the usual answer for a ranch roof this old is a full roof replacement. After storms, hail damage roof repair can cover isolated hits, but brittle older shingles often crack across every slope.
Main Street, Camp Wisdom Road and Armstrong Park
Duncanville's grid is easy to learn. Main Street runs north–south through the old downtown, where a few older commercial buildings with flat roofs remain, and Camp Wisdom Road, Wheatland Road and Danieldale Road cross the city east to west. US 67 cuts across the east side toward Cedar Hill, and I-20 crosses the city, which is where most of our trips enter town. Armstrong Park and the smaller neighborhood parks sit among streets of single-story brick ranch homes, with a scattering of 1980s two-stories toward the Cedar Hill and DeSoto lines. Strip centers along Camp Wisdom and Main add low-slope commercial roofs to the mix.
The trip from Irving runs down Loop 12 or SH 360 to I-20, then onto Main Street or Cockrell Hill Road, so most addresses are a short hop once we leave the interstate.
