Norman’s warm humid summers and frequent severe thunderstorms drive repeated roof stress, especially on asphalt-shingle homes built before 1990 in Campus Corner and Downtown Norman. These older roofs often show leaks at step flashing around chimneys or at pipe boots where sealant has dried out after repeated freeze-thaw cycles in winter. Detection requires checking both the exterior and the attic because water can travel laterally under felt before appearing as a stain.
In Hall Park and near Lake Thunderbird, wind-driven rain from spring storms commonly forces water under ridge vents and skylight curbs. We use moisture meters and targeted probing rather than relying on visible drips alone, because cellulose insulation can hide active leaks until mold sets in. Homes in Moore and Noble also sit on flatter lots where poor drainage pushes water against foundation walls and up into eaves.
Cleveland County building practices from the 1970s and 1980s left many roofs with single-layer underlayment that fails faster under today’s storm intensity. We document every compromised seam and fastener line so homeowners can see exactly where water entered instead of guessing. This level of detail prevents unnecessary full-roof replacements when only localized repairs are needed.
Technician insight
In Norman the thing that catches most people out with roof leak detection and inspection is how far water travels under the felt on pre-1990 homes in Campus Corner after one of our big spring thunderstorms; they see a stain above the kitchen but the actual breach is three rafter bays away at a dried-out pipe boot.
Hall Park thunderstorm leak
Homeowner noticed a ceiling spot after a May storm. We found the leak had traveled from a lifted valley flashing near the garage, entered at the ridge vent, and soaked insulation two rooms away. We documented the path, replaced the flashing section, and dried the insulation before mold could start.
Roof Leak Detection & Inspection Services We Offer
✓Attic Moisture Mapping
Pinpoints active and past leak paths through insulation using meters and visual tracing so repairs target only the damaged sections.
✓Flashing and Sealant Inspection
Checks step flashing, vent boots, and skylight curbs where Norman’s wind-driven rain most often penetrates older shingle roofs.
✓Drone Ridge and Valley Survey
Captures high-resolution images of ridges, valleys, and gutters on two-story homes near the University of Oklahoma campus without ladder risk.
✓Emergency Leak Tracing
Rapid interior and exterior assessment during active storms to locate entry points before water reaches drywall in Downtown Norman or Hall Park homes.
✓Gutter and Downspout Evaluation
Identifies overflow points and improper slopes that push water under eaves on homes in Moore and Noble after heavy thunderstorms.

How it works
- 1
Exterior Walk and Visual Scan
We start on the ground and roof edges, noting missing granules, lifted shingles, and failed sealant around penetrations common after Norman’s spring storms.
- 2
Attic Entry and Moisture Readings
Inside we measure wood and insulation moisture levels at suspect areas, marking stains that trace back to ridge vents or pipe boots.
- 3
Targeted Probing and Documentation
We lift shingles only where meters indicate moisture, photograph every compromised flashing, and map water travel paths for the homeowner.
- 4
Written Findings and Repair Plan
You receive a marked diagram plus prioritized repair list that distinguishes immediate fixes from items that can wait until the next dry window.
Pricing
Most Norman roof leak detection and inspection jobs fall between $175 and $450 depending on roof access and number of suspected entry points.
