Most KC homeowners pay their final roofing invoice without checking the work.
That’s exactly when it matters most.
Shingle installation looks simple from the ground. It isn’t. Every row overlaps the one below by a precise amount — typically 5 to 6 inches of exposure. When that’s inconsistent, water finds channels between courses and works its way down before it ever hits the gutter.
What proper installation looks like:
Consistent row exposure across the entire field. Edges aligned at rakes and eaves. No visible nail heads in completed field shingles. Starter shingles sealed at the eave line.
What bad installation looks like:
Uneven row exposure. Exposed nail heads in the middle of the field. Gaps or misalignment at roof edges. Courses that visually drift — which means water is drifting too.
Before you pay the final invoice:
Walk the perimeter. Look at row consistency from a low angle at the side of the house. Check the edges and valleys. If something looks rushed or uneven — ask. A legitimate KC roofer will walk you through it without hesitation. A bad one won’t.
Most installation issues don’t show up as leaks immediately. They show up in year 3 or 4 when the warranty conversation gets complicated.
