New Construction Roof Defects: What DFW Buyers Should Watch For

The Dirty Secret of New Construction Roofing in DFW
The Dallas-Fort Worth metroplex added over 50,000 new homes in 2025, and that pace continues into 2026. With builders racing to meet demand, roofing quality sometimes takes a back seat. At S&B Roofing, we inspect hundreds of new-construction roofs every year — and what we find might surprise you.
Common Defects in New-Build Roofs
These issues appear repeatedly in homes across DFW's new developments:
Improper nail placement — High nails and nails in the wrong zone are the most common defect, compromising shingle wind resistance
Missing starter strips — Some builders skip starter strips at eaves and rakes to save time
Inadequate flashing — Step flashing at walls, chimney flashing, and valley flashing shortcuts are epidemic
Insufficient ventilation — Builder-grade ventilation often doesn't meet code minimums for the actual attic space
Poor pipe boot installation — Plumbing vent flashings incorrectly installed or using cheap materials that deteriorate quickly
Debris left on roof — Nails, cut shingles, and construction waste trapped under shingles and in gutters
Why These Defects Happen
The root causes are systemic:
Subcontractor pressure — Roofing subs are often paid per square, incentivizing speed over quality
Limited oversight — Municipal inspectors have too many homes to inspect thoroughly
Material shortcuts — Builder-grade materials meet minimum code but don't perform well in Texas conditions
Timeline pressure — Builders push for fast completion, and roofing is often rushed to get homes dried in
How to Protect Yourself as a Buyer
Whether you're buying from a national builder or a custom home builder:
**Hire an independent roof inspector** — Don't rely on the builder's inspection or the general home inspector's roof assessment
**Inspect before closing** — Issues found before closing give you maximum leverage
**Document everything in writing** — Verbal promises from builders are worthless
**Understand your warranty** — Builder structural warranties typically cover the roof for 10 years, but cosmetic issues may only be covered for 1-2 years
**Know the materials** — Ask for manufacturer, product line, and color specifications for all roofing materials
What to Look for During Your Walk-Through
Even without roofing expertise, watch for these red flags:
Uneven shingle lines — Step back and look at your roof from the street; crooked lines indicate careless installation
Visible gaps — Any daylight visible at flashing points or roof edges
Mismatched materials — Different shingle colors or styles indicating patchwork repairs already
Sagging between rafters — Visible waviness in the roof surface
Gutter debris — Excessive granules and debris in gutters from sloppy installation
Builder Warranty vs. Manufacturer Warranty
Understand the difference:
Builder warranty (1-10 years) — Covers installation defects but often has narrow definitions and requires builder-approved contractors for repairs
Manufacturer warranty (25-50 years) — Covers material defects but requires proof of proper installation; voided if installation was improper
