How To Build Sloped Roof 1 4 Over 12

For example if you measure 4 inches the pitch of your roof is 4 12.

How to build sloped roof 1 4 over 12.

Rain and snow which tend to congregate on flat roofs runs off a sloped roof keeping the lifespan of the roof and appearance intact. Simply locate a roof rafter board place the end of the level against the bottom edge and measure from the 12 inch mark vertically to the bottom edge of the rafter. Basically a slanted roof style is a flat roof tilted high up at one edge to create a very steep slope. A ratio is the most common way of expressing roof pitch or roof slope but degrees are also possible.

Once you ve determined the measurements you need mark them directly onto a series of 2 in 5 1 cm x 4 in 10 cm or 2 in 5 1 cm x 6 in 15 cm boards using a carpenter s pencil. Pitch ratios range from 2 12 to 12 12. It s similar to a shed or lean to roof or a clerestory roof but has one visible difference. A low pitched roof would be 2 12 and it means that over the space of 12 inches the roof only rises two inches.

Significantly cheaper to build than a gable or multi slope roof since there s less material in the roof. A sloped roof is a great way to prevent water from puddling on your roof. It has a greater slope. The rafters on a steeply sloped roof for instance will be much longer and have more end cuts than those on a flat roof.

This will give you the rise over run or pitch. Thus a 4 12 pitch would be a 33 slope. You can also divide the rise over run multiply by 100 and get a percentage.
