How to replace your roof

The project, of course, is bigger than the roof itself.
Water-damaged fascia and soffit areas should be repaired now. Because they aren’t accessible when the roof is on, if you repair them later, it can damage the roof and cost three to four times as much. Damaged or improperly installed flashing should be replaced to prevent water damage. Wall flashing is the biggest source of leaks.
Deteriorated siding may also need replacement to securely tie in your new roof, and you may want to replace your chimney cap.
Check the flashing around skylights or consider removing them altogether when you have your roof replaced. They tend to let heat and cold through and can leak.
