How do you know when you need a new roof?

A metal roof is a great alternative to a shingled roof. In fact, you can go ahead and install metal roofing right over shingles if you want to. But beware: you can only install the metal over shingles if the roof has four layers of shingles or less on it already. Start by laying a slat board base with 1-by-4-inch pine boards every two feet on your roof. Work from bottom to top. Attach these with 3-inch wood screws in every corner. Next, install metal edging around the perimeter of your roof. Use 1 1/4-inch roofing nails every 4 to 6 inches to nail it to the roof. Banish leaking roofs and loose tiles by hiring a professional roofer with the right skills and insurance to tackle tough roof-repair jobs.
