How to replace your roof

Performance matters

Next, assess how your current roof has held up to time and the elements.

Start by thinking about what, if anything, you dislike about your roof, says Todd Miller, president of Classic Metal Roofing Systems in Piqua, Ohio.

Are you replacing it sooner than you expected? Is your house too hot? Do weather extremes batter your roof?

Adjusting attic ventilation and choosing the right roofing material can solve your problems.

Where you live impacts this choice. While asphalt shingles can be used in cold climates, they can wear quickly in places that are warm year-round. Fiberglass shingles are a better choice. Metal is another good option because it can reflect sunlight and allow snow and ice to slide off. Concrete tiles withstand extreme cold well because they resist cracking, but many roof structures are not strong enough to support them.
