Roof Inspection Checklist Before Construction
Before construction begins, the roof deserves close attention. Whether you’re planning a remodel, addition, or full rebuild, an early roof inspection can prevent delays, unexpected costs, and structural issues once work is underway. A thorough checklist helps ensure the existing roof can support the project—or reveals when repairs or upgrades are needed first.
At S-Line Contractors, we treat roof inspections as a critical pre-construction step. Here’s a practical checklist to guide smart planning before construction starts.
1. Overall Roof Condition
Start with a general assessment of the roof’s condition:
- Visible sagging or uneven areas
- Missing, cracked, or damaged materials
- Signs of aging or wear
If the roof is already failing, construction should pause until issues are addressed.
2. Roofing Material Assessment
Different roofing materials age differently. Check for:
- Brittle or curling shingles
- Cracked or shifted tiles
- Worn membrane seams on flat roofs
Material condition impacts whether repairs or replacement are needed before construction.
3. Structural Integrity
The roof structure must support construction loads. Inspect:
- Rafters or trusses
- Ridge beams
- Roof decking
Weak framing can compromise safety during construction.
4. Signs of Water Damage
Water damage often hides beneath the surface. Look for:
- Interior ceiling stains
- Soft decking
- Mold or mildew smells
Active or past leaks should be resolved before new work begins.
5. Flashing and Penetrations
Roof penetrations are common leak points. Inspect flashing around:
- Chimneys
- Skylights
- Vent pipes
- Roof-to-wall connections
Damaged flashing should be repaired before construction.
6. Drainage and Slope
Proper drainage is essential, especially for flat or low-slope roofs. Confirm:
- Water flows toward drains or gutters
- No ponding areas
- Clear scuppers and downspouts
Drainage problems can worsen during construction if ignored.
7. Ventilation and Airflow
Roof ventilation affects moisture control and energy efficiency. Check for:
- Blocked vents
- Improper attic airflow
- Excess heat buildup
Poor ventilation can impact both construction and long-term performance.
8. Roof Age and Remaining Lifespan
Knowing the roof’s age helps with planning. Consider:
- Manufacturer lifespan
- Maintenance history
- Past repairs
If replacement is imminent, it’s often best to coordinate it with construction.
9. Code and Permit Considerations
Roof changes during construction may trigger code requirements. Review:
- Local building codes
- Structural load requirements
- Energy efficiency standards
Early compliance avoids inspection failures later.
10. Safety and Access Planning
Construction crews need safe roof access. Inspect:
- Stability for foot traffic
- Tie-off points
- Areas requiring reinforcement
Safety planning protects workers and prevents damage.
Why This Checklist Matters
Skipping a roof inspection before construction can lead to:
- Mid-project delays
- Unexpected repair costs
- Structural risks
- Failed inspections
A proactive checklist keeps projects on schedule and within budget.
