The invention discloses a sunshine room roof leakage-proof method. Primary drainage channels and secondary drainage channels are formed in primary beams and secondary beams, and leakage holes are formed in the secondary drainage channels of the primary beams and communicated with the primary drainage channels. Drainage channel openings of the primary drainage channels of the secondary beams are higher than drainage channel openings of the primary drainage channels of the main beams, and a large amount of rainwater is freely drained from top to bottom. During second drainage, bearing bosses are formed on the outer side walls of the secondary drainage channels of the primary beams and the secondary beams, rubber channels are formed in bearing surfaces of the bosses, waterproof rubber is mounted in the rubber channels, glass is pressed on the waterproof rubber by the aid of weight, and the rainwater is stopped at the secondary drainage channels by the waterproof rubber and guided into the secondary drainage channels of the primary beams. The rainwater flows into the primary drainage channels through the leakage holes in the secondary drainage channels of the primary beams and is smoothly drained. The invention further discloses a sunshine room roof structure. Organized drainage is realized, roof leakage is effectively avoided, wires and pipes are distributed, the cost is low, and the heat insulation effect is fine.
