What Type of Roof Is Best for Solar Panels?

Many roof types work well for solar panels, but here are the top ones to consider:

1. Mounting Solar Panels on Shingle Roofs

Shingle roofs are the most common type of roofing on homes in Nigeria, and they can be made of either composite or asphalt shingles. Composite shingles combine materials such as laminate, wood, and slate. Asphalt shingles are made of a cellulose mat or fiberglass with asphalt added during production.

While both are flexible, composite shingles tend to be more durable. Installing solar panels on shingle roofs is simple, requiring standard penetrating mounts that easily attach.

Technicians drill studs into the roof, attach the solar panels, and seal all gaps with flashings to prevent water leaks. Shingle roofs are cost-effective and durable, lasting 12–20 years, perfect for solar panels that will remain for decades.

2. Mounting Solar Panels on Metal Roofs

Metal roofs are excellent for solar installations and are among the easiest to work with. Homes with standing seam metal roofs allow technicians to attach solar panels without drilling, saving on labor costs.

Metal roofs reflect sunlight that doesn’t hit the panels, keeping homes cooler, ideal for hot areas of Nigeria. They are extremely durable, lasting 40–125 years, but they cost 2–3 times more than other materials. Solar panels also reduce the noise during rain.

3. Mounting Solar Panels on Tile Roofs

Tile roofs can support solar panels using standard penetrating mounts. Tiles may need to be cut or removed for mounting. Tile shingles, made from clay, slate, or concrete, are heavier and more expensive than shingle roofs but are long-lasting and generally more waterproof.

Clay tiles require careful movement by installers to prevent breakage, but Freedom Solar’s team is trained to handle them safely.

4. Mounting Solar Panels on Tar and Gravel Roofs

Flat tar and gravel roofs can also accommodate solar panels. Panels need tilt brackets set at about 30 degrees to optimize sunlight capture. Flat roofs are easier to work on, but hiring skilled installers ensures proper orientation. Tar and gravel roofs are budget-friendly and last 20–25 years.

Roof Angle and Direction

Best Roof Angle: ~30 degrees for optimal energy output. Adjust slightly for seasonal latitude differences.

Steep Roofs: Over 40 degrees may reduce energy output or make full solar installation impractical.

Flat Roofs: Weighted (ballast) mounting systems stabilize panels without drilling, and tilt-up brackets maintain the 30-degree angle.

Best Direction: South-facing roofs are ideal in Nigeria’s Northern Hemisphere. Southeast or southwest is also acceptable.

Roof Space and Strength Requirements

Space Needed: Depends on panel type, home size, and energy usage. One square foot generates ~15 watts. Average homes require 400–600 square feet for 19–23 panels. Consider skylights, dormers, or chimneys.

Weight: Panels and mounts weigh 3–4 pounds per square foot. Flat roof ballast systems weigh more due to concrete blocks. New roofs in good condition can support solar installations. Maxeon panels are particularly lightweight at ~33 pounds each.

Are Solar Panels Bad for Your Roof?

Panels aren’t harmful if installed correctly. Drilled holes for mounting are sealed with lag bolts, sealant, and flashings to prevent leaks. Proper installation ensures roofs remain protected throughout the 30–35-year solar panel lifespan.

Solar Panel Design Considerations

Worried about aesthetics? Black shingles pair well with solar panels. Freedom Solar Nigeria offers panels with all-black solar cells and anti-reflective glass for a sleek, modern look. Beyond looks, panels represent sustainability and your commitment to clean energy.
