Waterproofing upstairs deck

We have a 20m2 deck over our garage: plywood with a waterproofing sealant. The waterproofing is completely broken and water has been seeping through. The plywood needs to be replaced and recovered with a new system like butynol or bitumen. We want to extend the deck about 1 m2 on one side (to add stairs later, not included in this job). There will be a floating deck on top of the bitumen (not included in this job). The tradesperson needs to have experience in waterproofing decks, give a guarantee and be certified. We also have a job waterproofing our tiled roof on Builderscrack.
