Steep- Slope Roof

By Scott Rodgers

The top segment of a building is covered with a roof. The roof prevents the building and its components from the consequence of the weather. Chiefly the roof defends against rain. But taking into account the characteristics of the home, the roof may also defend against heat, sun rays, against chilly winter and against wind.

A leaky roof can damage ceilings, walls, and furnishings. The durability of a roof is a matter of concern because the roof is often the least accessible part of a building for purposes of repair and renewal, while its damage can have serious effects.

There are two parts to a roof, one supporting structure and the other weatherproof layer. The roof structure is generally supported upon walls. The supporting structure of a roof usually comprises beams that are long, strong and of rigid material.

During the money crises the rise of roofers does not affect the profession as compared to other business as most roofing job comprises of mending and renewing. These roofers mend and construct roofs prepared of tar and gravel, rubber, metal or shingles to prevent the home and its components from the liquid loss.

There are two types of roofs one is low-slope and other is steep-slope. Low-slope roofs rise four inches per horizontal foot or less and are installed in layers. Steep-slope roofs rise more than four inches per horizontal foot and are usually covered in shingles.

These low-slope roofs are mostly shielded with multi spread elements. Generally these roofers distribute a spread of insulation on the roof surface. On the uppermost of the insulation a layer of liquid bitumen is stretched. It is of tar like element. When it is done then they join a part of one by one layers through a fabric impregnated in bitumen on the flat surface.

Before including one more layer these roofers take the help of a mop to draw the hot bitumen. With this the seams are tightened and makes the surface watertight. These roofers go on with another steps again and again to draw the requisite layers. It is always made that the top layer is smoothened using a polish or gravel mixed with hot bitumen to develop a gloom look.

An increasing number of low-slope roofs are covered with a single-ply membrane of waterproof rubber Roofers must make sure the building is strong enough to hold the stone ballast.
