How to do a flat roof on a shed.

I decided to take full advantage of the regulations and build a 10 x 14 shed. First cut your rafter boards to size using a circular saw to make sure they fit your roof. Cut five 8 foot 2 by 4s for the horizontal supports across the top of the shed for the flat roof. I decided on a slanted roof.

Mauerlat must be. Lay them flat across the two 10 foot walls parallel to the 5 foot walls and equally space them out.

At inside vertical corners tom cuts and overlaps the epdm then uses rubber adhesive to glue it down tightly.

Install your shingles to the top edge of your lean to roof. At the first stage the mauerlat is installed. Once your walls are uneven you can build a slanted roof to fit. If both walls are the same height you can either raise one by adding plates to it or you can build a frame for the wall separately and then install this on top of the wall.

In the lower end of the rafter leg cut out. For additional stability you can also use steel joists that are built into one or both of the walls. For their forming take a pine board with a thickness of 2 inches. Make a birdsmouth notch at the end of each rafter to help it fit into place.

If the gap allows you to put another course of shingles then do it. Having a manual for warm flat roof construction with details and a summary of rules to follow helps. I didn t want ridges or valleys which are a lot of work and can leak. If there is only a little space left then you re fine and don t have to lay another row yet.

Place it at the ends of the outer wall on the pre fixed waterproofing material. Start at one end of the storage shed roof and lay the underlayment material onto the flat roof surface making sure that there are about 2 inches extra on either end to hang over the edges of the shed s flat roof.

I liked the idea of having a bit more greenery in the property we live. To keep the vertical sections from peeling off the walls tom screws on metal brackets called termination stops then cuts off the excess above the brackets. He also seals this seam with uncured rubber.
