Tarp Over Flat Roof

Came out to the shop this morning to find a fresh water leak.

Tarp over flat roof.

When ones roof is damaged it is only natural to want to stop any water from getting inside which also happens to be one of your insurance company s primary concerns. Put n ails in the board at least 10 apart for a secure connection. Lay the tarp flatly over the damaged area and make sure there are at least 4 feet of it overhanging past the roof s peak and the rest over the eave. Rain or sun reversible silver and brown 10 x 12 foot.

Extend the top edge of the tarp over the ridge of the roof. Lay the tarp across the roof so that at least 4 feet 1 2 m lies on the sloped part of your roof on each side known as the peak. Again nail the tarp to a 2 x 4 as you did on the other side. This will prevent water and debris from entering the damaged area.

Never lay the tarp out during a storm. If needed cut off the excess tarp from the other end leaving about a 4 overhang. Most self adhering tarps don t stick well to wet surfaces so make sure that the roof s surface is dry. Positions several 1 2 pieces of lumber on the tarp running vertically down the slope of the roof.

Attach the 1x2s through the tarp and into the roof decking with eight penny nails about every 16 inches. This will hold the tarp tight to the roof and keep the water out. Let the rest of the tarp hang off the lower border of the roof that overhangs the wall known as the eave. More importantly the tarp should be long enough to hang over the roof s peak allowing the water to flow downhill without seeping into the tarp s undersides.

Secure the tarp s remaining sides with additional 2 x 4 boards using your screw gun and screws. Using cap nails attach one of the tarp s peak ends to a 2 x 4. Fully secure your roof tarp to prevent flapping. Here s how to temporarily tarp a roof to keep your stuff inside dry until you can repair it rig.

Lay more 2 by 4s on either side of the tarp and attach those as well for a tight well secured water barrier. While it may take weeks or even months to get a roofer out to repair the damage a tarp can be put in place pretty quickly. Then fold the excess tarp under a few rotations for a tight clean fit. The screws must pass securely into the roof.

Lay the tarp out flat over the roof. The 2 by 4 should be about 2 feet longer than the tarp width. Stretch a tarp flat on the roof. Screw the 2 by 4 directly into the roof to secure it.
