Why start at the eave
Before climbing onto the roof, a skilled inspector gathers critical clues from the eave while still on the ladder. This quick, low-risk check reveals the roof’s layer history, likely replacement costs, and immediate red flags—helping homeowners make confident decisions without unnecessary surprises.
How to read shingle layers at the eave
- Count the visible layers at the front edge.
- Two layers at the eave edge usually mean a single layer covers the roof; the extra strip is the starter row used to seal the first course and reduce wind uplift.
- Three layers at the edge indicate two full layers on the roof. That’s typically the code-allowed maximum and means a full tear-off will be required at replacement.
- Why this matters for homeowners.
- Fewer layers can mean a cheaper re-roof because a second layer can be added without a tear-off.
- More layers mean higher replacement cost and more labor because the old material must be removed.
Flashing inspection at the eave
- Check for presence and correct installation.
- Properly installed flashing at valleys, rake edges, drip edges, and transitions prevents water intrusion.
- Missing, loose, or improperly seated flashing is a common cause of leaks even on otherwise sound shingles.
- What to flag immediately.
- Exposed fasteners, gaps between flashing and roof surface, or corroded sections that could let water track under shingles.
What this quick eave check tells you about roof condition
- Cost implications — layer count affects whether a tear-off is needed and therefore the project budget.
- Leak risk — poor or missing flashing at the eave is a common source of future leaks.
- Maintenance planning — early identification of problems lets homeowners plan repairs before they become emergencies.
