Step by Step: How Secret Roofing Is Installed in Ghana

1. Start With the Right Architectural Design

• Begin with accurate building measurements, especially considering the unique architectural features often found in Ghanaian homes, such as inner courtyards and wide verandas.
• Work with a professional architect or roofing expert who understands the local climate and design standards to tailor the roof accordingly.

2. Construct Parapet Walls

•  Build parapet walls around the perimeter of the roof. These act as visual barriers that hide the roofing sheets from view.
• Ensure the walls are sturdy and high enough to fully cover the roof while maintaining the overall structural integrity of the building.

3. Install a Low Slope Roofing System

• Use a roofing pitch of at least 5 degrees to allow water to flow off the surface. Ghana’s heavy rainfall demands a slightly steeper slope for better drainage.
• Overlap metal sheets correctly to prevent leaks.
• Install hidden fasteners that are corrosion resistant to suit the country’s humid conditions.

4. Integrate Concealed Gutter Systems

• Concealed gutters are essential in secret roofing. They collect rainwater without being visible.
• Ensure the gutter system is properly sloped to direct water into downpipes and away from the building’s foundation.
• Oversized gutters are recommended to handle Ghana’s frequent and heavy rains.

5. Apply High Performance Waterproofing

• Install waterproof membranes beneath the roofing sheets. Bituminous membranes or liquid applied sealants are ideal for Ghana’s hot and wet climate.
• Pay special attention to flashing at parapet wall joints, corners, and roof penetrations to eliminate the risk of water leakage.

6. Ventilate the Roof Properly

• Install ridge vents or soffit vents to allow airflow and prevent condensation.
• Consider adding thermal insulation under the roofing to regulate indoor temperature and reduce energy costs.

7. Inspect, Maintain, and Protect

• Regularly check for blockages in gutters, cracks in the parapet walls, and water pooling on the roof.
• Clean out leaves, debris, and refuse, especially after the rainy season.
• Repair small damages promptly to avoid costly renovations.

Disadvantages of Secret Roofing in Ghana

• Drainage Challenges: Improper slope or inadequate gutter systems can lead to water pooling and leakage, especially during Ghana’s rainy seasons.
• Shorter Lifespan: Some materials used in secret roofing systems may last only about 15 to 20 years, compared to traditional pitched roofs that last over 30 years.
• Regular Maintenance Required: The concealed nature of the roof means debris can accumulate in the gutters, requiring frequent cleaning and inspections.
• Risk of Poor Workmanship: Without expert installation, flashing errors and waterproofing failures can lead to serious structural problems.

Common Mistakes to Avoid With Secret Roofing

Even small errors can lead to big problems like leaks, mold, or structural failure. Here is what to watch for:

• Poor Alignment: Uneven roof panels can trap water.
• Substandard Materials: Cheap roofing sheets may rust or break in a few years.
• No Maintenance Plan: Secret roofs require regular cleaning and inspections to avoid blockages.
• Inadequate Drainage: Do not rely on basic gutters. Design your drainage system to fit the rainfall levels in your area.
