How Much Of Drop Should Patio Roof With Plastic

Some additional considerations for this project.

How much of drop should patio roof with plastic.

The slope should be at least 1 inch for each 8 feet of patio. For example a 12 foot patio will need 1 inches of slope. Nail trim limber to all corners and to front and back where panels meet roof. Apply front and back panels similarly to side walls.

One contractor said 1 1 4 1 1 2 inch we wouldn t notice but i find that really hard to believe and gave me question as to his integrity. Cut to fit pitch of roof and around vent. Fasten aluminum ridge roll flashing to each panel as you proceed. However an ideal roof drop per foot should be at least one eighth to one quarter of an inch per foot.

Determine the amount of slope needed for the size of the paver patio. The pitch of a roof is arrived at by dividing the vertical rise and its horizontal span or what people in the roofing industry would refer to as the slope. Some building codes start at one quarter of an inch per foot or two percent. Install vent as close to roof peak as possible.

Anything less than one eighth of an inch may pool on the roof. The minimum pitch for a roof is 1 4 12 which translates to 1 4 inch rise to 12 inches of run. However you can only use this pitch with built up roofing or specialized synthetic roofing. A 16 foot patio will need 2 inches of slope.

I know the standard is to have 1 4 drop per foot but have you ever been on a patio with a steeper grade and it still get relatively flat. Roof pitch in layman s language simply refers to the steepness of the roof. If the span under your deck is 12 ft for example the purlin at the outer end of the deck should be 3 in. To provide drainage the panels should slope toward the outside edge of the deck about 1 4 in.
