Maximum Water Control Where Roof Slopes Meet.

At Modern Roofing & More, we supply precision-formed Aluzinc valleys designed to integrate seamlessly with premium roofing systems. The Aluzinc Valley is a critical roofing accessory installed at the internal angle where two roof slopes meet. Its primary function is to collect and channel heavy rainwater safely down the roof, preventing leakage, structural damage, and premature roof failure.
Manufactured from high-quality Aluminium–Zinc (Aluzinc) coated steel, our valleys are engineered for superior corrosion resistance, durability, and long-term performance, making them ideal for Ghana’s heavy rainfall and humid conditions.

Why the Valley Is One of the Most Important Roofing Components.
1. Handles Concentrated Water Flow

During Ghana’s heavy rainy seasons, valleys receive and direct large volumes of water. A high-quality Aluzinc valley:

  • Prevents overflow and backflow

  • Reduces risk of roof leakage

  • Protects underlying trusses and ceilings

2. Prevents Structural Damage

Poor-quality or rusted valleys can cause:

  • Ceiling stains

  • Wall dampness

  • Wood or steel corrosion

  • Costly repairs

Aluzinc valleys significantly reduce these risks.

3. Long-Term Corrosion Resistance

Since valleys are constantly exposed to flowing rainwater, corrosion resistance is critical. Aluzinc provides far superior protection compared to ordinary galvanized materials.

Installation Considerations

For maximum performance, valleys should:

  • Be properly aligned and securely fixed

  • Have adequate overlap with roofing sheets

  • Be installed with correct pitch and drainage direction

  • Connect efficiently to Aluzinc rain gutters

Correct installation ensures leak-free performance and long-term roof integrity.

What Is an Aluzinc Valley?

An Aluzinc valley is a formed metal channel placed along roof intersections to guide concentrated rainwater runoff into gutters and drainage systems.

Because valleys handle the highest volume of water on a roof, they must be made from materials that resist corrosion and structural weakening.

Aluzinc Coating Composition (AZ Standard)

Our Aluzinc valleys are manufactured using industry-standard alloy coating:

  • 55% Aluminium – Provides strong corrosion resistance and heat reflectivity

  • 43.4% Zinc – Offers sacrificial protection at cut edges and water-contact zones

  • 1.6% Silicon – Enhances coating adhesion and long-term durability

This composition ensures exceptional performance in coastal, humid, and high-rainfall areas across Ghana.
