When violent thunderstorms or severe weather move through your town, nerves aren't the only thing wind and rain can rattle. Often, homes sustain minor damage from these systems, and your roof is particularly susceptible to the effects of wet weather.
You can use cardboard to temporarily patch rooftop holes, buying some time until a professional is able to repair the problem. Simply place some cardboard inside a plastic bag, and then put it under the shingles [source: Readers Digest]. Your makeshift cardboard patch won't hold out forever, but it helps keep a home dry in a pinch.
Any leftover cardboard from your patching project can be reused to make a playhouse (see idea No. 1). This'll keep your kids occupied until the severe weather system moves from the area and your soggy yard dries up.
