What Leak Detection Involves

Leak detection starts with a thorough roof inspection using moisture meters and thermal imaging to pinpoint where water seeps into your structure.

Our local roofing contractor examines shingles, flashing, underlayment, and roof deck to identify failure points before catastrophic damage occurs.

We document damage with photos and Xactimate data for insurance claims.

If active leaks are present, we deploy emergency tarps over affected areas to prevent water from wicking deeper into attic insulation, rafters, and structural framing.

Leak detection reveals problems hidden behind attic walls—wet insulation, rotted joist ends, mold on ridge beams.

We assess whether the roof substrate is compromised and needs replacement decking, new underlayment, or just spot repair with roof cement and sealant.

For specialty roofs like slate, cedar shake, metal panel, or standing-seam, we inspect fastener corrosion and panel seam separation.

Moisture meter testing across roof decking and attic substrate to locate hidden saturation zones
Visual inspection of asphalt shingles, architectural shingles, and granule loss patterns from hail or age
Flashing examination at all penetrations: step flashing, counter-flashing, chimney flashing, pipe boot, vent boot, and skylight seals
Soffit, fascia, rake, and eave condition assessment for water entry points where gutter overflow seeps behind trim
Attic ventilation duct and soffit vent inspection to confirm air movement prevents moisture trapping
Documentation of ice dam damage, wind-driven rain patterns under flashing, and hail strike marks
Xactimate reporting for insurance adjuster and supplemental claim support

Warning Signs of Trouble

Water stains on attic rafters, ceiling drips during heavy rain, or musty mold smell are unmistakable signals.

In Hillsborough's freeze-thaw winters, ice dams pool water on roof valleys and ridges, allowing water to wick under shingles for weeks.

Spring and summer hail strikes create cracks in three-tab shingles and puncture rubber flashing.

Humid summers promote algae and moss growth that traps moisture against the substrate.

Water stains or discoloration on attic insulation, rafters, joists, or ridge beam structure
Dripping water from ceiling interior, soffit vents, or exterior wall corners during or after rain
Missing, curled, or buckled shingles exposing underlayment and roof decking to weather
Granules accumulating in gutters and downspouts, indicating shingle erosion from UV and hail damage
Ice dam backup after snow melt, with water pooling on roof valleys for 24+ hours
Visible algae or moss growth on roof surface, retaining moisture and promoting decay

Our Detection Process

Upon arrival, we set up a safety harness and scaffolding to safely access rooflines and steep gable ends.

We photograph existing exterior conditions, then systematically inspect the roof deck substrate, sheathing composition (plywood or OSB), and fastener condition (nails, screws, ring-shank nails).

We test ice-and-water shield integrity at critical points like eaves and valleys where water backs up.

We examine counter-flashing at chimneys, step flashing at dormers, and apron flashing at parapet edges.

We check ridge cap and ridge vent seals, verify vapor barrier hasn't trapped condensation, and inspect for roof rot and wood decay.

For complex homes, mansard roofs, or multi-story structures, we use drones to survey roof overhangs, canopy areas, and metal panels difficult to access by ladder.

We test for rot in wood decking by probing with a pry bar and documenting soft spots needing replacement shingles or substrate repair.

Safety setup: ladder, harness, roofing square, nail gun, and air compressor for fastener inspection
Roof deck moisture mapping with thermal imaging to detect cold zones and wet substrate areas
Substrate assessment: plywood warping, OSB delamination, rot, decay, and structural sag in hip and gable areas
Fastener inspection for overdriven nails, missing fasteners, and ring-shank nail integrity in starter course
Flashing and sealant condition at valleys, apron flashing, boot flashing, and scuppers around chimneys
Gutters and downspout clearance verification for proper drainage and no overflow backup behind fascia
Attic ventilation: soffit vent blockage, attic fan operation, purlin and batten airflow, and vapor barrier function
Written estimate and repair prioritization with material spec (GAF, Owens Corning) and building code compliance

Costs & Timeline in Hillsborough

Leak detection typically costs $350–$650 for a standard residential inspection, depending on roof size, complexity, and attic access. Most inspections complete in 1–2 hours.

For homes with finished attics or multiple roof planes (hip, gable, mansard), add 30–45 minutes.

If permanent repairs are needed—shingle replacement, flashing resealing, decking replacement, or ice-and-water shield renewal—costs range from $500 to $5,000+.

Emergency tarping is available 24/7 at $300–$800 per tarp deployment. Permanent repairs are scheduled after insurance adjuster approval, usually within 5–7 business days.

Insurance Claims & Warranty

We document all findings using Xactimate software, the insurance industry standard for damage assessment. This ensures your claim is comprehensive and minimizes dispute risk.

We coordinate with your adjuster, attend inspections, and pursue supplemental claims when additional damage is discovered after tarping reveals hidden rot, decay, or wood deterioration.

Repair work carries manufacturer warranty on materials—GAF and Owens Corning asphalt shingles, premium underlayment, ice-and-water shield, felt roofing paper, drip edge, and adhesive—plus our 10-year workmanship guarantee on all sealing, flashing installation, fastening, and caulk work.

Why Hillsborough Roofing Pros

In Hillsborough's Somerset County climate, freeze-thaw cycles damage rubber pipe boot flashing and chimney counter-flashing. Spring and summer hail strikes puncture membranes and crack valley seams.

Humid summers promote algae, mold, and moss.

Our team knows these local failure patterns and catches problems early—before water seeps into framing and joists, degrading roof structure.

Signs You Need Roof Leak Detection

⚠

Water Stains on Attic Rafters

Brown or yellow discoloration on wood rafters and joists indicates active leaks that have persisted through storms or freeze-thaw cycles.

Hillsborough's heavy winter snow can trigger ice dam backup, allowing water to wick under shingles for days.

⚠

Ceiling Drips During Rain

Water dripping from ceilings, soffit vents, or interior walls during heavy rain is a sign that flashing, shingles, or underlayment is failing.

Wind-driven rain from spring thunderstorms is common in Somerset County and often finds gaps in counter-flashing.

⚠

Missing or Curled Shingles

Hail strikes and freeze-thaw cycles cause asphalt shingles to curl, split, or go missing entirely. This exposes roof decking and underlayment to direct water intrusion.

Granule loss in gutters is a warning that shingles are nearing end-of-life wear.
