Valley Flashing 450 mm × 3.600 m – 0.4 mm Galvanized Steel Roof Flashing
The Valley Flashing 450 mm 3.600 m 0.4 mm, supplied by SA Home Builder Store, is a high-quality galvanized steel roof flashing designed to protect roof valleys — the area where two slopes meet. It ensures a watertight seal, channels rainwater safely down to gutters, and prevents leaks, water ingress, and roofing structural damage — making it essential for any pitched roof using metal sheeting, tiles or other roofing systems.

- Install along the roof valley where two slopes meet, beneath or overlapping roofing sheets/tiles as per roofing standard practice.
- Ensure correct overlap and sealing at joints and ends — to prevent water ingress especially in heavy rainfall or storms.
- If using with metal sheeting (e.g. IBR, corrugated), make sure to use compatible fasteners and follow purlin spacing / support guidelines to maintain structural integrity.

- For coastal or corrosive environments — consider using higher-grade coatings or additional protective paint/sealant for extended durability.
