Waterproofing a rooftop deck is critical to protect the underlying structure from moisture damage and ensure longevity. Begin by ensuring the roof deck is clean and free of debris. Next, check for any existing damage or weak spots that need repair. For waterproofing materials, you can choose from liquid membranes, rubberized coatings, or bituminous sheet products, depending on your budget and the specific needs of your deck. Applying a waterproof membrane is expected; this involves rolling or spraying the membrane over the surface, ensuring all seams and junctions are tightly sealed. Drainage is another important consideration; installing proper drainage solutions will help prevent water accumulation. Finally, consider adding a protective layer over the waterproofing, such as tiles or wood decking, to protect the membrane from physical damage and UV exposure.
