Roofing FAQs
What is the best waterproofing system for a flat roof?
The best system depends on the substrate, usage, and expected lifespan. Liquid-applied systems like polyurethane and GRP are popular for their seamless finish and flexibility. Bitumen-based options are more traditional and still widely used. Acrylic membranes offer easy application and fast curing. Each has its advantages based on roof complexity, foot traffic, and weather exposure.
Can I apply roofing systems myself or should I hire a contractor?
Many roofing products are DIY-friendly, especially complete kits and liquid membranes designed for single-day application. However, larger projects or complex details such as parapets, drains, or junctions may benefit from professional installation to ensure long-term success. Always follow product instructions carefully.
How do I prepare a roof before applying a waterproofing system?
Clean and inspect the surface, removing loose debris, moss, and contaminants. Repair cracks or damaged areas, and ensure the substrate is sound. Apply a suitable primer if required, and make sure the roof is dry and stable before beginning the main application.
What accessories or extras might I need alongside a roofing system?
In addition to the primary coating or membrane, you may need primers, reinforcement fleece, trims, sealants, application tools, and cleaners. These support adhesion, detailing, and durability. Many roofing kits include these items, but standalone systems may require separate components.
