Benefits Of Waterproof Membranes On Rooftop Decks

To reduce the amount of deck repair needed on rooftop decks, many people use waterproof membranes underneath the surface floor to protect from damages. The decks are typically constructed with a wood or concrete substrate and are waterproofed using protective waterproof membranes. While some deck repair is unavoidable such as sun damage or other weathering factors, there are ways to minimize it with waterproof membranes.

Some people might consider using outdoor carpeting. But while it may look appealing, it is not waterproof. When it gets wet, carpet tends to hold water and dry very slowly. If the carpet is laid without waterproof membranes underneath, water will likely permeate the concrete or wood substrate below, causing it to rot and deteriorate. Furthermore, carpet holds the water close to the deck and doesn't allow it to dry, therefore increasing the potential damage. Beyond that, outdoor carpet fibers tend to deteriorate rapidly through exposure to the sun. Frequently, frayed and unsightly outdoor carpets need to be replaced.

Of course, there are foundational problems that can occur to the surface over the protective membranes that will require basic deck repair. Concrete, for example tends to shift in response to daily temperature fluctuations. This kind of constant movement can put enormous stress on the foundations, causing moisture to penetrate into the concrete.
