Abstract
A one-piece shield for temporarily covering the upper inlet of a downspout. The shield includes a single sheet of resilient material, with a pair of tabs that cooperate with a slot in the sheet. The sheet is rolled up to create a tubular portion. One of the tabs is turned into the tubular portion to block the passage into the tubular portion, and the other tab cooperates with the slot to keep the device rolled up, so that the tubular portion blocks entry of debris into the downspout. The device is unrolled after use, and stored flat.
