First, ensure the installation surface is sturdy and level, and clear the roof of debris, dust, and oil stains.

Resin tiles must "align with the purlins without deviation." FRP transparent sheets must "snap onto the side peaks of the steel panels."

The installation direction is clearly specified: resin tiles start "from the bottom of the roof," while FRP sheets are laid "from the eave toward the ridge." This is a fundamental requirement for waterproofing.

Both emphasize that direct hammering is prohibited, and expansion space must be reserved.

Resin tiles require "fixing with nails," whereas FRP sheets explicitly state that "pre-drilling is necessary before fixing, with a hole diameter 6–9 mm larger than the screw diameter," and waterproof gaskets must be used.

Resin tiles rely on tight overlapping and correct installation sequence for waterproofing.

FRP sheets explicitly require "applying two strips of waterproof tape" and "using waterproof gaskets" for active sealing, indicating higher waterproofing demands.

After installation, a final inspection and adjustments are required for both materials.
