Roof flashing is a vital component of roofing systems. Is intended to prevent water infiltration at points where the roof meets walls, chimneys, vents, or other structures.

TOP ROOF FLASHING COMPANY IN SINGAPORE :

In Singapore, where heavy rainfall is common, proper roof flashing is essential to maintain the integrity of buildings and prevent water damage.

There are several types of roof flashing commonly used in Singapore:

Lead Flashing: Lead flashing is another popular choice due to its flexibility and longevity. It can be molded to fit tightly around complex roof features, providing a watertight seal.

Metal Flashing: Metal flashings, typically made of aluminum, copper, or galvanized steel, are durable and effective at diverting water away from vulnerable areas. They come in various shapes and sizes to suit different roof configurations.

Bitumen Flashing: Bitumen flashings, also known as asphalt flashings, are made from bituminous materials and provide a waterproof barrier. They are commonly used in conjunction with asphalt shingles and built-up roofing systems.

PVC Flashing: PVC flashings are lightweight and cost-effective. They are commonly used in areas where corrosion is a concern, such as coastal regions.

Rubber Flashing: Rubber flashings, often made from EPDM (ethylene propylene diene terpolymer), offer excellent resistance to UV radiation and extreme weather conditions. They are flexible and easy to install, making them suitable for curved or irregular roof surfaces.

It's essential to ensure that roof flashing is installed correctly by trained professionals to prevent leaks and water damage. Regular inspections and maintenance are also necessary to detect any signs of deterioration and address them promptly.
