What is a Roofing Cap Sheet What is a Roofing Cap Sheet. Used in low slope roofing such as built-up roofing (BUR) or modified bitumen roofing, a cap sheet is used to create a water-tight surface. Constant exposure to wind and weather can cause a BUR roof to become brittle and crack, then water can seep into the cracks, eventually working into the interior of the building.

What Is Modified Bitumen Roofing? Developed in Europe in the mid-1960s, modified bitumen roofing has been used in Canada and the United States since about 1975. It was developed as a means to improve roofing membranes when product quality was affected by the use of a lower-quality crude oil by-product.

The tiles were designed to provide maximum coverage to reduce cost.Although originally intended to be installed on top of a sub roof such as waterproofed ply wood or alternatively corrugated metal sheet roofing.he tiles simply clip onto 8 mm diameter rods in the usual overlay pattern spaced at 250mm, the tiles can also be stapled or nail onto wood roof battens. The FiberPalm tiles installed without a sub roof will provide you with a 98% waterproof roof covering.

Flat Roof Repair These need to be constructed with a good quality weather proof and waterproof material and torch down roofing can be one of the best options for this. Torch down roofing is also commonly known as rubberized asphalt and is considered one of the best options for flat roofs or those that have a gentle slope. The material is typically modified bitumen which is combined with resins and is supplied in rolls. It gets its name from the fact that to install it a blow torch is used to melt the seams of the bitumen rolls as they are laid which secures them tightly to the roof and also provides a waterproof seal between the rolls.

Flat roof Construction methods. Any sheet of material used to cover a flat or low-pitched roof is usually known as a membrane and the primary purpose of these membranes is to waterproof the roof area. Materials that cover flat roofs typically allow the water to run off from a slight inclination or camber into a gutter system. Water from some flat roofs such as on garden sheds sometimes flows freely off the edge of a roof, though gutter systems are of advantage in keeping both walls and foundations dry.

Modified Bitumen Roofing Asphalt degradation is a growing concern. UV-rays oxidize the surface of the asphalt and produces a chalk-like residue. As plasticizers leach out of the asphalt, a modified bitumen or mod bit roof becomes brittle. Cracking and alligatoring inevitably follows, allowing water to penetrate the system causing blisters, and cracks. Seam failure inevitably follows causing leaks. Leaks in modified bitumen roofs are difficult to isolate and a seamless roof coating system is a cost effective solution. The surfacing of the sheets is also a maintenance concern. Modified Bitumen sheets are not as sensitive to ultraviolet light as built up roofs but there is still degradation. Studies have indicated that a reflective coating applied within five years of installation can extend the service life of the membrane by 10 or more years.

- For asphalt flat roofs, several membrane layers are necessary (built up flat roof felt). Only one membrane layer of TPO membrane is required, however, since TPO is a single-layer roof covering. Ridge vents are installed along the roof peaks for the purpose of ventilating the roof timbers and attic space.
