Your roof is the most expensive exterior system on your home, and it degrades silently. UV radiation bakes the granule coating off asphalt shingles. Thermal cycling cracks sealant at flashing transitions. Wind lifts shingle edges and loosens ridge cap. Diagonal Roofing & Maintenance's roof inspection catches all of this before it becomes a $15,000 emergency.
Attic inspection is the part most roofers skip. We check your soffit vents, ridge vents, and attic fan operation to verify balanced ventilation. Poor ventilation causes heat buildup that bakes shingles from underneath and ice dams in cold weather. We also check insulation levels and look for moisture, mold, or compressed batts that reduce R-value.
Our Roof Inspection Process
Book Online or Call
We'll confirm your inspection date and time. Let us know the purpose — annual maintenance, home sale, insurance claim, or post-storm — so our inspector brings the right checklist and documentation forms.
Rooftop Assessment
Full exterior roof walk. We check every square foot of shingles, every flashing transition, every penetration seal. Pipe boots squeezed for brittleness. Chimney flashing probed for gaps. Valley channels checked for debris buildup and wear. Photos taken of every finding.
Below-Deck Assessment
Below-deck inspection from the attic. We verify that soffit vents aren't blocked by insulation, ridge vents are continuous, and there's no moisture or mold on the sheathing. Ventilation problems shorten roof life dramatically.
Detailed Report
You receive a written report with annotated photos within 48 hours. Findings prioritized by urgency: critical (active leaks, failed flashing), moderate (worn shingles, marginal ventilation), and low (cosmetic, long-term maintenance). Repair estimates included.
