How to measure (10 minutes, no ladder)
You only need a tape measure or Google Maps. Break your roofline into straight runs and peaks, measure each one, and enter them in the kit builder.

Straight runs
Tape or measuring wheel
- Stand on the ground under the gutter.
- Measure corner to corner along the house. The gutter sits right above you.
- Write each run down with a name, like “Front gutter 38 ft.”
No tape needed
Google Maps
- Find your house in satellite view on a computer.
- Right-click the corner of the roof and choose Measure distance.
- Click along the roof edge to the other corner and read the length.
Peaks
Width + steepness
Don't climb. Measure the width of the wall under the peak at the ground, then pick how steep the roof looks below. The kit builder calculates both sloped edges for you, including the roof overhang.
How steep is your peak?
GentleRanch homes, low slope
StandardMost houses
SteepHard to stand on
Very steepTall, pointed peaks
Before you order
- Measure every section separately.We label each run with the name you give it.
- Round up to the next foot.We add 5% on top, so you're covered at corners.
- Find your outlet.Measure from the outlet to where the lights start. That's your lead length.
- Stay off the ladder to measure.Everything here can be done from the ground or a computer.

1Your roofline
Start from a house type (typical sizes, change them to yours):
Straight runs are gutters and flat edges. Peaks are the pointed parts: enter the width at the ground and we work out the sloped edges. See the measuring guide.
