Google Maps provides a method to measure your home's roofline dimensions remotely. This guide explains how to use satellite imagery and built-in measurement tools to get accurate measurements for installing exterior lighting, whether you're a contractor or homeowner.
What you’ll need:
A computer with internet access
Google Maps in your web browser
Your property address
Step-by-Step Instructions:
1. Access Google Maps
Visit https://google.com/maps in your web browser.
2. Switch to Satellite View
Hover over the "Layers" icon in the bottom left corner
Click "More" in the menu that appears
Select "Satellite" as your Map type
Ensure "Globe view" is checked to enable 3D viewing
Note: 3D viewing is primarily available in larger metropolitan areas. You can still measure rooflines without this feature by following the measurement steps.
3. Locate Your Property
Enter your address in the search bar to find your property.
4. Enable 3D Perspective
While viewing your property from above, click the 3D button on the right side of the window
Alternatively, hold down Ctrl and drag with your mouse on the map surface to change the 3D perspective
5. Take Measurements
Once you’ve gotten close to your home in 3D view, you can start to measure.
Right-click on one end of your roofline
Select "Measure distance" from the dropdown menu
Click the other end of the roofline segment to complete the measurement
To measure additional sections, right-click and select "Clear measurement" first
Repeat the process for all sections of roofline you plan to illuminate
Pro Tip: This measurement tool can also help estimate tree crown sizes for wrap lighting.
6. Calculate Total Length
Add all of your measurements together. You may wish to add 10-15% extra length to account for measurement variations.
Important Considerations
Measurements may not be perfectly accurate - use them as estimates
Consider breaking up longer sections into manageable lengths
Account for power cord routing between different roofline sections
Next Steps
Once you have your measurements:
Choose appropriate base wire lengths for your project
Select bulb type and spacing
Calculate the number of clips needed (one per bulb)
Plan your power source locations
