Over the years, roofing companies have improved the roofing of buildings and homes. Roofs are more durable, regardless of the weather and they are even fire proof. The roof is one of the core structures of the house, and it can cause total losses when it catches fire, as roof fires can spread very quickly depending on the material used. Roofing companies need to construct roofs in the safest way possible to ensure fire protection.
Roofing companies need to have knowledge on the roofing materials used as some spread fire very quickly, especially where there are catalysts like wind. Materials that are combustible like wood will easily and very quickly spread fire. Roofs of steel trapezoid sheets that are not favorably designed may spread the fire very easily. Roofing companies therefore have to put into consideration the materials used during roof construction. Priority should be given to the following materials during construction; vapor barriers with low fire loads, high polymer waterproofing sheets, e.g plastic and rubber, non-combustible thermal insulation materials, and mechanical fastener instead of bituminous adhesives. Materials which glow should not be used as materials in roof cavities.
For protection against flames, roofing companies should adhere to rules in DIN 18234-3. The regulations demand that skylight domes, smoke, and heat exhaust devices in the roof should have at least a clearing of 5.0 mm of firewalls; for small penetration sites like the piping roof drainage, the thermal insulation around this opening is to be designed in a surface area of 1x1m each with a non combustible material.
Combustible materials used for roof components like the ceiling, roof binders, wooden shells, and others should not be installed through firewalls and complex separation walls. This is because these materials will aid in the spread of a fire across the roof.
Resistance against fires largely depends on the fire penetrability of a roofing system of the building. Roofing regulations have therefore been set to provide a standard safety level for individuals in and around the building. The British standard test for roofing has classified roofs into different categories, A, B, C AND D. A means that the fire did not penetrate within one hour and there were no spread of flames, B means that penetration did not occur in less than half an hour and the flames did not spread more than 533 mm, D means that penetration occurred in less than 30 minutes and the fire spread more than 533 mm and D means penetration occurred in the preliminary flame test and continued to burn 5 minutes after the test. Roofs are required to be of type A or B to pass the test and considered as fire protection safe.
To encourage safety, roofing companies should ensure that construction documents are created and reviewed to minimize or entirely remove all fire hazards in the roof and add any additional necessary safety measures. The companies should ensure that only qualified specialists work on the roofing project and that only the materials needed for work are on the roof. These will prevent negligence and carelessness that may cause or spread a fire. In case of a fire, it is important that a fire extinguisher be available to help put the fire out. It is important that highly flammable materials like gas and bitumen be handled very carefully to avoid causing fires. Smoke detectors on the roof also help in controlling the spread fire using fire extinguishers.
Roofing companies play a bit part in ensuring buildings are protected against fire. These companies should therefore strictly follow these rules as fire is very destructive and can cause complete losses when they hit.
