See a New Roof on Your Own House

How to Use It

1. Choose a photo of your house, taken from the street in daylight.
2. Drag the four orange corners onto one face of your roof.
3. Pick a shingle line and a color. The roof changes, nothing else does.
4. Add another plane for each slope you can see in the picture.
5. Set the course size until the shingle rows look life sized.
6. Save the picture and take it inside to argue about over dinner.

Why It Looks Right Rather Than Pasted On

A roof plane is a rectangle seen at an angle, so the four corners you drag describe that angle. The shingle courses are then mapped into that shape, which is why they run parallel to your eave and close up toward the ridge the way real courses do.

Then the light in your photograph is kept. Every pixel of new roof is multiplied by the brightness that was already there, so the shade of your maple tree, the bright line along the ridge and the darker north slope all survive. That is the difference between a new roof and a colored shape lying on top of a photo.

Where Your Photograph Goes

Nowhere. There is no upload, no account, no email box to fill in and nothing stored. The picture is opened by your own browser, drawn on a canvas in this page, and it is gone when you close the tab. The Save button writes a file to your device and nothing else.
