The 21-Point Roof Inspection Checklist

Every DT Exteriors inspection follows this comprehensive checklist. Nothing gets missed.

Exterior Roof Surface (Points 1-8)

1. Shingle condition — Checking for curling, buckling, cracking, blistering, and granule loss
2. Missing or damaged shingles — Individual shingle assessment across all slopes
3. Ridge cap shingles — Condition and secure attachment along all ridges and hips
4. Roof valleys — Shingle alignment, flashing condition, and water flow path
5. Flashing condition — Around chimneys, skylights, walls, vents, and all penetrations
6. Pipe boots and vents — Rubber seal integrity, cracking, and proper fit
7. Ridge vent condition — Secure attachment, screen integrity, and airflow verification
8. Overall alignment — Checking for sagging, waviness, or uneven surfaces indicating structural issues

Drainage System (Points 9-12)

9. Gutter attachment — Secure to fascia board, proper slope toward downspouts
10. Downspout function — Directed away from foundation, proper extensions
11. Drip edge condition — Present and properly positioned on all eaves and rakes
12. Debris accumulation — Leaf and granule buildup in gutters and valleys

Penetrations and Seals (Points 13-16)

13. Chimney condition — Mortar joints, cap, crown, and flashing
14. Skylight seals — Weathering, caulk condition, and glass integrity
15. Sealant/caulk inspection — All visible sealant points checked for cracking or separation
16. Satellite dish/antenna mounts — Seal integrity around roof penetrations

Attic and Ventilation (Points 17-21)

17. Attic moisture — Checking for condensation, water stains, and mold
18. Insulation condition — Adequate depth, even distribution, no moisture
19. Ventilation adequacy — Calculating intake-to-exhaust ratio (should be balanced)
20. Soffit vent clearance — Ensuring insulation isn't blocking soffit vents
21. Structural condition — Rafters, trusses, and decking checked for rot, cracks, and deflection

In Wisconsin, we recommend roof inspections more frequently than the national average due to our severe climate:

• Every 2-3 years — Routine inspection for roofs under 15 years old
• Annually — For roofs over 15 years old
• After every significant storm — Hail 0.75"+, winds 60+ MPH, or tornado warnings in your county
• Before selling your home — A clean roof inspection report adds value and buyer confidence
• Before buying a home — An independent roof inspection can reveal issues a general home inspector might miss
