Green roofs, also known as living roofs, have become increasingly popular due to their numerous benefits, including improved aesthetics, enhanced energy efficiency, and positive environmental impacts.
A key step in the successful installation of a green roof is ensuring its waterproofing. Proper green roof waterproofing is essential to protect the building structure from potential water damage and ensure the longevity of the green roof.
Green Roof Waterproofing
Waterproofing a green roof starts with choosing the right materials. High-performance liquid membranes, such as LOTUS, are commonly used due to their excellent adhesive properties, seamless coverage, and long-lasting waterproofing capabilities.
The product effectively adheres to all substrates, creating a robust and durable layer of protection against water infiltration. Moreover, LOTUS, high-performance waterproofing solution is cold-applied and cold-cured, which makes their application user-friendly and efficient.
Green Roof Installation
Following the waterproofing stage, the green roof installation process begins. This typically includes installing a root barrier over the waterproof membrane, laying a drainage layer, and then adding the growing medium and the plants. The choice of plants depends on several factors including local climate, roof load capacity, and the desired level of maintenance.
Ongoing maintenance and regular inspections are crucial to the longevity of a green roof. This includes ensuring the waterproofing membrane remains intact and efficient, and the vegetation is healthy and thriving.
Green roofs can help to reduce stormwater runoff, improve air quality, and provide a habitat for wildlife but like any roof, green roofs can experience wear and tear over time. If your green roof has water damage, it's important to have it repaired as soon as possible to prevent further damage. The longer you wait, the more damage the problem is likely to cause.
There are a number of things that can damage a green roof, including:
Weeds and Pests
Weeds and pests can quickly take over a green roof if they're not controlled. This can not only make your roof look unsightly, but it can also damage the plants and the underlying waterproofing membrane.
Strong winds can uproot plants and damage the substrate. This can expose the waterproofing membrane to the elements, leading to leaks.
If your green roof leaks, it can cause significant damage to your home or business. Water can seep through the plants and the substrate, damaging the waterproofing membrane and the underlying roof deck.
Animals, such as raccoons and squirrels, can damage green roofs by digging up plants and eating the substrate.
Repairing the waterproofing issues of a green roof requires a careful approach, as you are dealing with both living plants and a complex roofing system. Depend on the extend of the damage, we will either repair or replace the substrate, or even the entire waterproofing membrane.
