In 1907 the first Zigfield Follies were performed on a theater roof. Fortunately the roof was in good shape. How's yours? Is it ready for anything? If you're not sure, it's time to inspect. If you hate heights, check things out from ground level with a pair of binoculars. If things look OK outside, climb into the attic to inspect the underside. Look for telltale stains on rafters and mildew that rots wood. If it looks good, check again after a rainstorm or bring out a hose and wet it down, one row at a time. Work from the bottom up with a helper inside to spot rows that are "leakers." With proper installation and ongoing care, you save two ways. First, you extend the life of your roof and save the cost of replacing it. Second, you prevent leaks that can damage your home's interior and contents. You'll also be ready for the pitter-patter of feet, whether dancing girls or eight tiny reindeer. And that's the On The House tip for today.
