There are various parameters which contributing to the ultimate roofing choice. There are obviously some physical elements that contribute to the choice and style of roofing. Then there are the choices related to the different flexible-membrane roofing alternatives.

Decisions pertaining to the choice of membrane and attachments are also crucial in terms of choosing the kind of roof you install in your house. Another important factor is definitely the dead load weight that the roof will add to your building structure.

Physical Factors Affecting the Choice

The location of your building is a very important criterion determining the roofing system. Moreover, the environmental factors in the form of topography, the climatic trends also contribute a lot to the decision.

The physical characteristics of the house itself, like in the form of its height, size, age and shape, contribute greatly to the choice of roofing. Apart from these, the other factors in the form of construction materials used for the building, the location of the fire protection equipments and the HVAC (heating, ventilation, air conditioning) system also determines the nature of roof.

Barring these factors, the other parameters, like edge detailing, access to the rooftop, and protrusions, are important as well in determining the quality and structure of roofing.

Choosing the Type of Membrane and Attachment

The choice of membranes is determined by the nature of roof you are planning to build. Basically there are three types of membranes from where you can choose from: thermosets, thermoplastics, and modified bitumen roofs.

Roofing made from thermoset membranes are made from robber polymers. That is why they are also known as rubber roofing. These membranes have the capability of protecting the roof from sunlight and chemicals, commonly found on roofs.

Thermoplastic roofing is normally made from fiberglass or polyester or a combination of both the materials. Now with the emergence of modified bitumen roofs, in the market, the buyers can enjoy the benefits of the flexible membrane roofing along with the assurance of the traditional built-up roofing setup.

Finalizing on the Attachment Style

The style of attachment is a critical element in the entire roofing scenario. Factors like the amount of weight the roof edge can withstand, the slope of the roof and the ballast system, all play a critical part in the roofing equation.

The quality of adhesive is also determined on the basis of the membrane used and the nature of attachment you chose for your roof.

Tile Selection

Again depending upon the membrane you have chosen for the roof you should choose the material of the tiles used for the purpose. Rubber, clay, asphalt, metal and wood tiles are few of the choices which you can opt for.

Each of the roof flooring systems has its specific advantages and hence before the final installation the entire discussion should be done with the roofing contractor.


Installing a roof on your house is considered as the final touch of your house building process. That is why it is important to conduct all the critical assessments including installation and maintenance considerations, accessory requirements, the roof design, selection of contractors, and the warrantees before installing the roof.
