Garden sheds receive a fair amount of abuse from weather conditions and lack of care. It is important to repair your garden shed, because a dilapidated shed can hurt the aesthetics of your yard. Likewise, sheds house expensive gardening equipment that should not get rusted. Generally, sheds suffer from leaky roofs. Tree branches, the sun and hail can damage roofs and create holes. Repair the felt roof and protect your lawn equipment from water, snow and wildlife.
Inspect the damage on the roof. Remove all the nails holding down the old felt. Use a claw hammer or a small pry bar. Look at the condition of the wood when you take off the old felt.
Patch damaged wood areas with new wood cut to the same size as the damaged piece. Nail the new wood into the roof.
Treat the wood roof with a wood preserver. Apply the wood preserver with a paintbrush. Pay attention to joints, edges and sides. Wait for the wood preserver to dry.
Measure the size of the roof. Use your measurement to cut pieces of felt. Cut with a Stanley knife an extra 50mm to wrap the felt down over the edge.
Nail with galvanised nails one side of the thatched roof and switch over to the other side. Cut a piece 200mm wide or large enough to cover the entire surface of the roof. Spread a layer of waterproof mastic seal underneath the piece and press the piece down on the ridge.
Use a stepladder when fixing your roof, because your weight may cause the roof to collapse when repairing.
Wear goggles and safety gloves to prevent the grit of the felt from coming in contact with your eyes or hands.
