TYPES OF ROOFING

METAL ROOFING

Metal is known for its exceptional strength. Metal roofing can last for up to 50 to 75 years when maintained regularly. With reflective finishes applied, it can drive your utility bills down because it can reduce heat absorption.

MODIFIED BITUMEN ROOFING

This roofing material fuses hot asphalt (bitumen) with plastic rubber additives layered between sheets of polyester or fiberglass. The lifespan of the modified bitumen roofing depends on the thickness or number of layers. It is also easy to install and low maintenance.

BUILT-UP ROOFING

When you’re on a tight budget, this kind of roofing is perfect. Built-up roofing is an economical option composed of three or more layers of fiberglass membrane coated with hot asphalt. It is then topped with gravel or mineral blends for protection from ultraviolet radiation from the sun.

TPO SINGLE-PLY MEMBRANE

This newer, heat-welded, single-ply roofing membrane offers a 10-year rating. TPO (thermoplastic polyolefin) roofing also costs less than PVC ones. Additionally, it can help reduce your energy costs since it reflects heat.

EPDM SINGLE-PLY MEMBRANE

With this rubber-based product’s durability, it’s no wonder it has gained popularity among commercial buildings. EPDM (ethylene propylene diene monomer) roofing can be ballasted, fully adhered or mechanically fastened.

FUNCTIONS OF ROOFING

➤ Insulation
➤ Drainage

INSULATION OF ROOFING

Because the aim of a roof is to secure people and their possessions from climatic elements, the insulating properties of a roof are a consideration in its structure and therefore the choice of roofing material. Some roofing materials, particularly those of natural fibrous material, like thatch, have excellent insulating properties. For people who don’t, extra insulation is usually installed under the outer layer. In developed countries, the bulk of dwellings have a ceiling installed under the structural members of the roof. The purpose of a ceiling is to insulate against heat and cold, noise, dirt and sometimes from the droppings and lice of birds that frequently choose roofs as nesting places.

Concrete tiles can be used as insulation. When installed leaving an area between the tiles and he roof surface, it can reduce heating caused by the sun. Forms of insulation are felt or plastic sheeting, sometimes with a reflective surface, installed directly below the tiles or other material; synthetic foam batting laid above the ceiling and recycled paper products and other such materials which will be inserted or sprayed into roof cavities. So called Cool roofs are getting increasingly popular, and in some cases are mandated by local codes. Cool roofs are defined as roofs with both high reflectivity and high thermal.

Poorly insulated and ventilated roofing can suffer from problems like the formation of ice dams round the overhanging eaves in weather, causing water from melted snow on upper parts of the roof to penetrate the building material. Ice dams occur when heat escapes through the uppermost a part of the roof, and therefore the snow at those points melts, refreezing because it drips along the shingles, and collecting within the sort of ice at the lower points. This can result in structural damage from stress, including the destruction of gutter and drainage systems.

DRAINAGE OF ROOFING

The primary job of most roofs is to stay out water. The large area of a roof repels tons of water, which must be directed in some suitable way, in order that it doesn't cause damage or inconvenience. Flat roof of adobe dwellings generally have a really slight slope. In a Middle Eastern country, where the roof could also be used for recreation, it's often walled, and drainage holes must be provided to prevent water from pooling and seeping through the porous building material.

Similar problems, although on a really much larger scale, confront the builders of recent commercial properties which often have flat roofs. Because of the hugequality of such roofs, it is essential that the outer skin be of a highly impermeable material. Most industrial and commercial buildings have conventional roofs of low pitch.In general, the pitch of the roof is proportional to the quantity of precipitation. Houses in areas of low rainfall frequently have roofs of low frequency while those in areas of high rainfall and snow, have steep roofs.
