Roof clip count
Estimate gutter, shingle, or fascia clips from eave and ridge feet divided by clip spacing.
Formula
clips = ceil((eave_feet + ridge_feet) ÷ (spacing_inches ÷ 12)) · optional spare %
Include gable rakes and ridges you will clip.
C9 often matches socket spacing (~12 in). Icicles may need 6–8 in.
FAQ
How far apart should clips be?
Many C7/C9 runs use about one clip per socket (often 12 in). Heavier icicle lines often look better at 6–8 in.
Do I count ridge and eaves separately?
Yes — add every run you will clip, then divide by spacing.
Why buy spares?
Clips break, freeze, or get dropped from ladders; a small spare pack avoids mid-install shortages.
Gutter vs shingle clips?
Use the clip style that matches the surface; this tool only estimates quantity from length and spacing.
