Waterproofing Options for Pitched Roofs

Waterproofing for roofs are unfortunately often overlooked. It is assumed that the roof no matter which material is supposed to prevent any water ingress into the building. Yes, it is true that one of main function of the roof is to protect the inhabitants from naturals elements like sun and rain but a slight damage to the primary roof material like a crack or a hole for instance can result in water seeping inside the building.

In this article we will discuss the importance of waterproofing especially for pitched roofs, examine the various waterproofing options available, and understand the benefits of ISOLINE under roofing sheets from ONDULINE, a modern solution offering not only waterproofing but also thermal comfort.

The Importance of Waterproofing your roof

Protection Against Water Damage

In a place like India, we are often prone to heavy rains accompanied by strong winds. This can lead to water seeping into the roof through holes or cracks or gaps in roof overlaps. This can further result in mildew and rot apart from damaging the interiors of your building.

Increasing the life of the roof

Waterproofing will help to extend the life of buildings by protecting them from the elements, ensuring they stand the test of time. This is particularly important for tropical regions where the combination of rain and heat accelerates wear and tear.

Improved Indoor Comfort

The waterproofing options available in the market offer many features apart from just stopping the water ingress into the building. These features will enhance the comfort of the people living under the roof.

What are the Waterproofing Options for Pitched Roofs?

Here we must consider the primary roof structure. If your roof is made of RCC then you can choose the below three options:

Bitumen waterproofing Membrane

This is a time tested and proven method for waterproofing. Bitumen waterproofing membranes can be self-adhesive or torch on. They are durable and resistant to extreme weather conditions. However, the one disadvantage is that it can increase the temperature inside the building.

Liquid Waterproofing

This method is very prominent now a days and most of the waterproofing players in the market has a variety of options for liquid waterproofing. This involves applying a liquid membrane that cures to form a seamless, waterproof layer. Various companies offer different life span for this method but on an average, it can last fool proof for up to 10 years depending on the composition.

EPDM Waterproofing Membrane

EPDM (Ethylene Propylene Diene Monomer) membranes are a synthetic rubber material known for their durability and flexibility. They last longer than liquid waterproofing and is widely used in commercial buildings. ?This membrane exhibits high tensile strength.

Now if your roof is made of discontinuous structure like metal or wood with primary roof like clay or concrete tile of metal or UPVC roofing sheets then you have the below options to waterproof your roof.

Roof Underlay

A roof underlay though very common in western countries is yet to gain popularity in India. There are different kinds of roof underlays which helps not only in waterproofing but also in heat insulation. ?A roof underlay is laid under the roof tiles or roof sheets to prevent any water seeping through primary roofing from entering the building.

ISOLINE Under Roofing Sheets

One of its kind in India, ISOLINE under roofing sheets made of Bitumen and Cellulose from the house of ONDULINE is a very common waterproofing product used across Europe and China. ISOLINE is installed beneath the primary roofing material, acting as another layer of roof that enhances waterproofing and insulation.

Advantages Of ISOLINE Under Roofing Sheets

Exceptional Waterproofing

ISOLINE is a roof under your roof. It effectively blocks any water that manage to seep through the primary roof and allow it to flow out along its corrugations.

Thermal Comfort

In addition to waterproofing, isoline sheets provide excellent thermal comfort. They help regulate indoor temperatures by allowing ventilation as well as reducing heat transfer. They can also be used along with other insulation materials such as rockwool to further reduce the internal temperature.

Compatibility with Various Roof Types

Isoline sheets can be used with a wide range of roofing materials, including roofing shingles, metal roofing sheets, clay, and concrete tiles. This versatility makes them an ideal choice for new constructions as well as renovations.

Noise Reduction

The excellent acoustic properties of isoline sheets also dampen noise from rain or wind, creating a quieter indoor environment.

Once installed, isoline sheets require minimal upkeep. Their robust construction ensures long-term performance without frequent repairs or replacements.

Conclusion

Waterproofing for pitched roofs is not just a functional requirement but an important step in ensuring the life of any building. For regions like India, where heavy rains and extreme temperatures are the norm, isoline sheets stand out as an excellent choice.
