Solar panel roof mounting
for Philippine roof types

Mounting systems for Spanish tile, corrugated metal, flat concrete, standing seam, and shingle roofs in the Philippines. Costs, methods, and waterproofing tips.

Mounting by roof type

Roof TypeMounting MethodDifficultyCost / PanelNotes
Spanish / Clay TileTile hook & flashingMedium₱5,000–₱8,000/panelRequires careful tile removal. Tiles are brittle — breakage risk.
Corrugated Metal / GI SheetL-foot brackets with sealantEasy₱3,000–₱5,000/panelMost common PH roof type. Fastest to install. Use neoprene seals to prevent leaks.
Flat Concrete RoofTilt rack / ballasted systemMedium₱6,000–₱10,000/panelBifacial panels ideal here. Tilt at 10–15° for optimal PH angle. No roof penetration needed with ballasted systems.
Standing Seam MetalClamp-on (no penetration)Easy₱4,000–₱6,000/panelClamp mounting means zero roof penetrations. Best for leak-proof installations.
Shingle / AsphaltFlashing & L-footMedium₱4,000–₱7,000/panelMore common in newer PH subdivisions. Flashing is critical for waterproofing.

Mounting installation process

1
Structural inspection

We inspect your roof structure to ensure it can support the weight of solar panels plus wind loads (critical in typhoon-prone PH).

2
Rafter location marking

We locate roof rafters using stud finders and mark mounting points. Panels must attach to rafters, not just roofing material.

3
Flashing & seal installation

Waterproof flashings are installed at every penetration point. Neoprene seals and silicone provide double protection against PH monsoon rains.

4
Rail attachment

Aluminum mounting rails are bolted to the flashings. Rails run perpendicular to panels and provide the structural base for the array.

5
Panel installation & wiring

Panels are clamped to rails, wired in series/parallel, and grounded. MC4 connectors ensure weatherproof electrical connections.

Roof mounting FAQs

Corrugated metal (GI sheet) roofs are the easiest and most affordable to mount solar panels on. Flat concrete roofs are excellent for bifacial panels. Both are very common in Philippine homes.
