just keep an eye on those drainage layers, or you’ll have more than zombies pooling up there.
That’s no joke. I once inspected a garage where the owner had tried a DIY green roof—looked great until a big storm hit. The drainage was clogged, and the whole thing sagged like a wet sponge. Malarkey shingles would’ve saved him some grief, honestly. They’re lighter and you don’t have to worry about roots poking through. Still, I’d double-check the rafters on anything older than the 80s... some of those old sheds just aren’t up for surprises, zombie or otherwise.

That’s spot on. I replaced the roof on my ‘77 workshop last year and found a few cracked rafters—wouldn’t have noticed until it started bowing. Malarkey shingles went on easy, but honestly, if your structure can’t handle the weight or a sudden downpour, even the best shingles won’t save you. Always check what’s underneath before you upgrade.
