2 Side Slope Roof

This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.

2 side slope roof.

These roofs have a pitch less than 4 12. This roof was built without sufficient pitch about 2 12 and it leaks badly during heavy rains as you can see by our photograph of the roof s under side above right. Generally such roofs have a pitch ranging from 1 2 12 to 2 12. Asphalt shingles can only be installed on roof slopes of 2 12 or greater.

Mansard roofs can help create a great deal of extra living space. Box gable roofs have two sloping sides that meet to form a ridge with a triangular extension on either side that is boxed off from the walls. Raising the high end of this shed roof a few inches will improve the roof drainage and stop the leak problem. A reversed gambrel or mansard roof with the lower portion at a lower pitch than.

Gambrel roofs are the traditional barn style roof. The sides can either be flat or curved depending on the style. This means for every 12 horizontal units the roof must rise a minimum of 2 vertical units. The picture makes it easier to understand than to explain.

The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7. The upper slope is low pitched and the lower slope is high pitched. A pitched extension of a main roof similar to a lean to but an extension of the upper roof. Conventional roofs are the easiest to construct and you can walk on them safely.

Also if asphalt shingles are installed on a roof slope of 2 12 to 4 12 it shall be provided with a double underlayment application. A gable roof with one side longer than the other and thus closer to the ground unless the pitch on one side is altered. Photography by marc lamkin.

This type of roof is popular for areas with cold weather conditions providing a stable design that deals well with rain and snow. A mansard roof also known as a french roof is a four sided roof with a double slope on each side that meet forming a low pitched roof. The style consists of 2 sides with a ridge at the peak just like gable but each side actually consists of 2 different pitches.
