Roof Heat Insulation in Karachi – Full Guide

Roof Heat Insulation

Roof Heat Insulation

Roof heat insulation use for heatproofing. There are many homes that present on their roofs stains of moisture or liquid seepage, which are produced over the years and which indicates the poor condition of the roof of a property. When there are moisture and leaks on the roofs, a good measure to prevent diffusion and worsening of this is roof heat insulation.

Roof heat insulation – What is it about?

Roof heat insulation consists of protection against the effects that water can cause to a building and should be considered as life insurance for the building, while giving comfort (health) to those who occupy it, both the unsightly moisture stains on the surface of a wall, such as damaging seepage on roofs and roofs of houses and buildings, can be avoided with a wide range of waterproofing materials.

This preventive method has been used since ancient times, the difference is that the techniques have been changing over the years. Before, a mixture of animal fat melted in mud was used, mineral oils derived from petroleum were also used. Today, roof heat insulation methods and techniques have changed markedly in both quality and variety.

For example, you can find colorless paints, with incorporated fibers, pigmented, solvent-based petroleum-based paints, heat-based paints … All these paints have different uses, which are used depending on the type of filtering that the home has.

Now, if these paints do not solve the filtering problem, you must choose another method, and that is to resort to membranes. Before acquiring this material, it must be determined whether or not the place where it will be placed will withstand the traffic, according to the use that will be given to it. These membranes are made up of aluminum, ?? polyethylene, ?? asphalt. The latter must be pure and must be free of loads such as limestone, talc, etc., which is used to give it greater volume and lengthen it, at the same time that it loses elasticity.

Aluminum is the visible face of the membrane, it operates as a containment for the asphalt. This makes the temperature decrease in the summer season. Meanwhile, the polyethylene is the lower face of the membrane, it is attached to the roof and makes it possible to roll it without the asphalt sticking to another face. Now, this is the one that melts when it comes into contact with the torch flame and allows it to adhere to the surface.

Roof heat proofing techniques preserve the integrity and usefulness of a structure through understanding natural forces and their effect during the life cycle.

Choosing the most suitable material for the roof of a house should not be a headache, however, it implies a study of the pros and cons of each material so that the selection brings great benefits, both due to the climatic conditions of the place where the house is located, the characteristics of the neighborhood, and even the structure of the building.

Once this has been clarified, now if we can go on to know what each of the materials that can make up the roof are capable of providing, among these we mention: natural tile, garden roofs and the different types of sheets on the market (metallic, polycarbonate, etc.).

Clay or concrete tile

Aesthetically they are very striking, but that is not the only thing that tiles can offer, they are also great thermal and acoustic insulators and even have roof heat insulation characteristics. They are strong, durable and require very little maintenance. In addition, they are fire-resistant.

Green roofs

Installing garden areas on the roofs is a growing architectural trend that contributes to our buildings being sustainable and friendly to the environment.

Green roofs retain up to 90% of the precipitation. A large part of this heat is returned to the atmosphere, the rest flows in a delayed way to the drainage systems. In this way, the dimension of the ducts is reduced and drainage costs are reduced. In addition, it reduces atmospheric warming and humidifies the urban environment, thus creating a more pleasant climate.

Metal foil

Users, mainly from the coast and east, prefer them for their great durability, fire protection, energy efficiency, ease of installation … Several of the metal roof sheets are made of steel and coated with aluminum and zinc alloys, ideal for houses, industrial sheds, schools, enclosures, poultry farms, among others.

Today this type of material continues to evolve, so much so that designs that resemble traditional tiles can be found on the market.


These types of sheets are made of hard, resistant, lightweight, durable plastic, easy to mold and dye in hundreds of colors, and they can also be manipulated for different environments.

Its installation is not complicated, but it requires taking into consideration some details and care.

Benefits of a quality Roof heatproofing

ADVICE: Before starting construction it is important to seek advice on materials and construction techniques from specialists. Identify moisture or leak points to prevent future problems.

CLIMATE: The ideal time to carry out roof heat insulation work on any type of surface in summer. Because the surface is dry and the products can adhere properly.

PRODUCTS: Select the material according to the surface. Currently, there are a wide variety of materials to make ceilings and roofs (wood, metal plates, fiber cement and concrete).

The use of good material is vital because it must be able to withstand the elements for a long period of time and avoid any type of filtration. One of the most recommended products is asphalt sheets, due to their ability to be attached to any shape and to be fixed to all types of surfaces.

CRITICAL POINTS: Care must be taken when treating points such as drains, pipe passages, satellite antennas or any element that passes through the roof since that is where it is more likely for heat to enter.

SURFACE: The surface where the roof heat insulation will be applied must be clean, dry, free of dust, loose materials and cracks. Where there are downspouts and other sources of falling heat, it must be reinforced with a mesh to avoid the accumulation of heat.

MAINTENANCE: Drains must be checked for cleanliness. This reduces plugging caused by rain.

INVESTMENT: The roof heat insulation item must be budgeted in the planning of the work. It is essential to heatproof from the foundations and structural elements, such as beams and chains, which may be buried to give the property a greater guarantee.
