Regardless of your roof type, hurricane straps are designed to help hold the roof to the walls. Ask your builder to install hurricane straps of galvanized metal. Don't wait until after your house is constructed; although some people attempt hurricane-strap installation as a do-it-yourself project, the straps are difficult to fit, and improperly placed, they can turn into sharp projectiles in a strong wind.
If your extension cord gets tangled up, don’t pull on the ends. Instead, gently loosen all the tighter snarls in the middle until them become larger loops that can easily be untangled. A way to avoid tangles is to use a retractable cord reel. It will let you reel out only the amount of cord you need, then quickly reel it back when you’re done.
