Appreciation post: My 'waterproof' shed roof leaked after the first heavy rain in Seattle last fall because I used the wrong underlayment.
I learned the hard way that a $30 roll of basic roofing felt isn't enough for our constant drizzle, and now I'm looking for a better sealant for the plywood before I re-shingle, so has anyone used that peel-and-stick ice and water shield stuff on a shed?

Peel and stick is serious overkill for a shed roof unless you're building it in a literal swamp. That stuff is expensive and a pain to work with compared to just using a decent synthetic underlayment. A good 30-pound synthetic felt will handle Seattle drizzle just fine if you install it right. Save the ice and water shield for the critical spots on your house, not the garden shed.

Yeah, that peel and stick stuff is super sticky and can be a real pain if it gets hot... heard it can even melt a bit and slide around.

Wait, did chen.olivia say a 30-pound synthetic is enough for Seattle? I gotta disagree there, the constant damp here is a different beast. That peel-and-stick IS a pain, but for a small shed roof it's not that bad or expensive. It's the only thing that really seals around the nail holes, which is where most leaks start after a few years. A basic underlayment just can't do that, no matter how well you install it.

Wasn't there a thing about that sticky stuff needing a really clean surface to stick right? I read that any dust or grit on the plywood makes it fail way faster, which seems like a big hassle for a shed. A good synthetic underlayment might just be less fuss in the long run.
