I nailed my shed felt flat across the middle of every sheet just to stop it lifting in the wind: the first heavy downpour, I understood what each of those nail heads had opened
A homeowner discovers that nailing roofing felt across its open middle—a common mistake—creates puncture holes that let water pour straight through during heavy rain. The first downpour revealed what each nail head had unwittingly opened: a direct path for water into the shed. Proper felt roofing depends entirely on overlap placement and nailing strategy, not scattered fasteners.
