Starting at the bottom, glue one layer down. Remember to let the ruffled edge overhang the bottom edge of the roof.
Overlap the next one, offsetting the ruffle pattern, like a real roof. Leave some room between each row. Continue layering the rows to the top.
Also, make sure to glue a bit of the strip to the roofing card, over the bottom row. This will make the shingles rise and look more natural, not flat. You will need about 13 or so strips depending on the spacing between the rows.
Place the top most row square with the roof peak edge. You may need to make a few cuts to straighten it out.
Continue the same for the other side. |
