Home improvement expert Bill McAnally often urges people to fix problems in their homes immediately. With roofs, though, sometimes it pays to wait.
"Let's say it isn't leaking, but it's looking pretty bad. Some people say 'I really need a new roof.' Looks-wise, yea. But if it's not leaking, then stretch it out as much as you can."
He says most people in Iowa never get full usage out of their 75-year shingle warranties because of the storms common to the region.
