This style of roof or curb roof includes a four sided hip roof style with two distinct slopes. The mansard roof is a combination of gambrel and hip roof.

Different designs of mansard roofs and truss systems imply the use of different materials. The surface will carry a serious load when snow or strong winds so avoid even the slightest deviation in construction. The run or the base number is 12 inches. A mansard roof is a four sided gambrel roof with each side having a double slope of one steep slope and one shallow upper slope.

The lower ends of the pans are typically hooked over an edge strip to form a drip. Simply put the mansard roof also known as the french roof or curb roof is a hybrid between a gambrel roof and a hip roof. For example a slope of 6 12 means for every 12 inches of horizontal distance the slope of the roof will rise 6 inches vertically. You may not see such roofing style in most traditional homes but they can be easily found in barn houses and similar modern places.

The rise will be the elevation change over the 12 inches.

The steeper angle can be found on one side and the window creates an extra floor of space in a home called a garret. In buildings with a mansard truss roof structure the main structural engineer must ensure that together with the truss the surface structure of the floor complies with the vibration requirements of ril 120 the finnish design code for timber structures. Well the roof particularly defines the form of art rather than just making an architectural design for functionality.

The ends may alternately attach to the base flashing where a change in roof slope occurs.
