PROBLEM TO BE SOLVED: To provide a waterproofing method of sheets in the way that they are mechanically fixed, where judgment is easy on whether each waterproof sheet has been well joined with its fixing metal fittings, and the quality deterioration of waterproof sheets due to temperature rises can be prevented to more improve their durability. SOLUTION: The waterproofing method of sheets is characterized in that fixing metal fittings 3 with their upper surface coated over with a resin for joining together are fixed to a ground body 1 with a fixer, and a transparent or translucent waterproof sheet 5 is laid on and joined with these fixing fittings 3. Then an opaque colored protection layer is formed on the surface of each translucent waterproof sheet 5. The method is also characterized in that the colored protection layer has a reflectivity of infrared rays within a wavelength range of 700 to 2,100 nm, which results in a 40% or more sunlight reflectance .
