Things You'll Need:
- Wood pieces (at least 3 inches tall) Roof staple gun Waterproof roof coating Paint brush or air spray gun Pond liner Potting soil Gravel Sod
-
Step 1
Check the structural integrity of your roof to make sure that it is strong enough to hold the weight of the sod. Make any needed repairs. Look for signs of water damage, rot and broken tiles. If you are not sure if your roof is strong enough, hire a roofer to evaluate the roof. Wet sod roofs are heavy. If needed, hire a roofer to construct support beams to strengthen the roof.
-
Step 2
Line the exterior edges of the roof with pieces of wood that are at least 3 inches tall. Secure the wood to the roof using a roof staple gun.
-
Step 3
Paint a waterproof roof coating on your roof to protect it from possible water damage from the sod. Use a paintbrush or spray gun to apply the coating. Allow the roof coating to dry for 24 hours.
-
Step 4
Lay pond liner over the roof. If more than one pond liner is required, overlap the edges to create a good water barrier. Make sure the pond liner covers the whole roof. Use a utility knife to cut the pond liner to size where needed. Staple the pond liner down to the roof, every few inches along all the edges, using a roof staple gun.
-
Step 5
Spread 1 inch of potting soil evenly on top of the pond liner. Spread 1 inch of gravel evenly on top of the soil for drainage. Spread another 1 inch layer of potting soil on top of the gravel.
-
Step 6
Lay pieces of sod over the dirt. If needed, use a utility knife to cut the sod pieces to size.
-
Step 7
Spray the sod roof lightly with water.
