LeafGuard – Polypropylene Flat Roof Drain & Downpipe Protector
Stop blockages before they start. The Leafguard flat roof drain protector is designed for flat roof drainage outlets, parapet drains, scuppers, and gutter downpipes, LeafGuard is a durable polypropylene filter that prevents leaves, moss, and debris from entering your drainage system.
What Is LeafGuard?
LeafGuard is a lightweight yet robust polypropylene insert that fits neatly over or inside flat roof drainage outlets, hoppers, and downpipe openings. Its precision-engineered mesh or grille pattern allows rainwater to flow freely whilst capturing organic debris before it can cause costly blockages.
Unlike metal guards that rust or corrode, LeafGuard is 100% weather-resistant, UV-stabilised, and unaffected by standing water, making it ideal for the UK's year-round roof drainage demands.
Key Benefits
Prevents drain blockages – Stops leaves, twigs, moss, and bird droppings from entering downpipes and underground drains.
Reduces maintenance – Extends the interval between gutter and drain cleaning visits, saving time and labour costs.
Protects flat roof membranes – Eliminates standing water caused by blocked scuppers or parapet outlets, reducing the risk of ponding and membrane degradation.
Polypropylene construction – Won't rust, rot, or corrode. UV-stabilised for long-term outdoor use.
Easy to fit – Simply place over the outlet or push into the downpipe opening. No tools, adhesives, or specialist skills required.
Removable & cleanable – Lift out when necessary, rinse with a hose, and replace. Reusable for years.
