Waterproofing Roofing Plywood
Am building a 16' X 24' gambrel roof barn. All the trusses up and have started nailing the plywood for the roofing. Since it doesn't look like I will be able to get the shingles put on before bad weather sets in, I was thinking about applying water sealant (Thompson's) to the plywood. The idea is to provide some protection for the plywood until the weather breaks in March before I put on the shingles. How bad is this idea?
Thanks in advance for any suggestions.

You could probably do that Have you thought of just putting on the roofing felt? You are most likely to be installing it anyways. If you staple it down well it should do what you want. Good luck.

Shingles can be installed in winter. The problem is tabs on asphalt shingles don't seal until temperatures reach the 50s. Cold shingles are more able to break free of tabs are not sealed. Shingles applied in hot weather often get too soft & when roofers walk on them they can be damaged. Most folks prefer fall or spring for installation.

Paper and Shingles
Do the tar paper and shingles.
While synthetic membranes as jmorgan1 will work and work well, they are also 3-4 times as expensive as regular tar paper with shingles over that...
