Asphalt Shingle Roof Replacement in Oak Cliff

This Oak Cliff homeowner had spent the last few years trying to keep a 30-year-old asphalt roof watertight. Each repair held for a season, and then another leak found a different path through the same tired shingles and underlayment. By the time we walked the roof, the question had stopped being whether to repair or replace — it had become which materials would still be working in another three decades. The home went from a single-layer shingle roof on aged felt to a full CertainTeed Climate Flex system installed over a freshly inspected deck.

Why a 30-Year-Old Roof Stops Holding Repairs

Asphalt shingles age in a few stages. The granule layer thins first, exposing the asphalt to UV. The asphalt loses its plasticizer, the mat shrinks, the keyway between shingles widens, and the underlayment beneath finally loses its ability to shed wind-driven water. Once a roof reaches that final stage — typically in the late twenties on an average DFW home — patches can stop sealing reliably, because the surrounding shingles may no longer accept new sealant or hold a fastener tight. That was the situation here: the field around each leak was past the point where a localized repair could integrate cleanly with the surviving shingles.

If you want a deeper read on how decisions like layer count, decking condition, and material tier move the number on a project like this, we wrote about that here: factors that affect roof replacement cost in Dallas-Fort Worth.

The Tear-Off and What We Found

The existing assembly was a single layer of asphalt shingles over one layer of felt underlayment. We removed both, exposing the deck for a full inspection. Two old turbine vent penetrations were no longer in service and had been left un-patched on the deck — a common find on homes that have been re-vented over the years. We patched the deck cleanly at both openings before the new underlayment went down, eliminating soft spots that would have telegraphed through the new shingles within the first few years.

Re-sheathing was not required. The decking was sound across the rest of the roof field, and the inspection confirmed it could carry the new system without modification.

The New System

The replacement assembly is built around CertainTeed Climate Flex impact-resistant asphalt shingles — an SBS-modified shingle rated for impact and engineered to stay flexible through the temperature cycling that breaks down standard architectural shingles in North Texas. Above and below the shingle layer:

• Synthetic underlayment. Certified Roof Runner across the field, replacing the old felt with a tear-resistant synthetic that handles foot traffic and weather exposure during installation.

• Ice and water shield. Certified ice-and-water at vulnerable areas — eaves, valleys, and around penetrations.

• Bronze drip edge. 2x2 metal drip edge along the eaves and rakes, color-coordinated to the new shingle field.

• New chimney counter flashing. The existing flashing was tied into the old shingle field and could not be reused. We cut new counter flashing into the chimney and integrated step flashing with the new shingle courses — a detail that prevents the next leak from starting at the most common failure point on an older Dallas home.

• Ridge ventilation. Six 3-in-1 ridge details handle exhaust airflow, supporting the attic ventilation balance for a two-story home in this climate.

The materials specification matters because it ties to our CertainTeed SELECT ShingleMaster certification and GAF Master Elite credentials — both of which require ongoing training and warranty backing on the manufacturer side. Those credentials are why the workmanship and material warranties on this project are written by the manufacturer, not by the contractor alone.

Where This Project Fits Locally

Oak Cliff homes built in the second half of the 20th century are aging into a wave of replacements right now. The original 25-to-30-year asphalt roofs that came with these homes — or that were installed during the early 2000s replacement cycle — are reaching the end of their service life within a year or two of each other. If you live in Oak Cliff or one of the surrounding neighborhoods inside the I-635 loop and your roof is at or past 25 years, this is the moment to get a baseline inspection on file — even if there is no active leak yet.
