Parapet Roof Materials

Roof pitch because parapet roofs are encircled by walls they are more prone to leaking than traditional pitched roofs.

Parapet roof materials.

Being made of synthetic rubber or polymer they are flexible and elastic and can handle temperature changes and some impact types better than built up roofs. Flat roofs of this type are usually finished in steel roof sheet and fall towards a special type of gutter called a box gutter. Thermoblock thermal break blocks reduce heat loss in parapet applications making insulation at the roof to wall transition continuous and the roof more energy efficient.

The parapet itself is standard wood framing with an applied siding in this case t g 1 4 cedar. They can also improve the proportions of a building by increasing the apparent height. Parapet walls can be constructed using different materials like reinforced cement concrete steel aluminium glass etc. These roofs are installed as thin sheet materials 0 030 30 mils to 0 060 inches 60 mils thick and are applied to the roof in a single layer.

Traditional tiles are made from terracotta clay but there are also ceramic tiles roofs made of fired clay as well as concrete tile roofs.

A parapet roof is simply put when a building s outermost walls extend upwards past the roof around the edges most often by a few feet.

All consist of individual tiles installed in overlapping layers over the roof surface and all have roughly the same degree of strength and durability. If you didn t get it right you concentrated the stresses at roof edges and you could suck in a parapet or tear or rip a membrane at the parapet photographs 3 and 4. While a roof parapet wall may seem like a small detail in the grand scheme of the entire building design it can actually change the dynamic of an entire roof both in terms of cosmetic detailing and safety. The assembly is straight forward but what complicates matters is that the roof needs to be vented.

Different types of parapet walls and their uses are discussed below. Courtesy of max baker and the national research council of canada. Parapets can also hide unsightly roofing material or equipment that is placed on the roof such as vents.
