What your roof (asphalt shingle) needs and how often, how long it usually lasts, and what replacing it tends to cost.
Check for lifted or missing shingles and flashing damage. A typical schedule is once a year.
Usually 20 to 30 years. Where yours sits in that range depends on when it went in and how it's been looked after, which is why the install year is the most useful thing to write down. Something past its typical life isn't due for replacing on that account: most things are run until they fail. It's a reason to put money aside, not to spend it.
Roughly $10,000 to $20,000 installed in the U.S. for a 2,000 square foot house, more or less in proportion to size. Treat it as a range for budgeting until you have a quote.
Generic schedules start from the calendar. Yours should start from your house. Keeping House takes the year each system went in and works out what's due and when, sends the reminders, and keeps the history a buyer or insurer will ask for.
Intervals and lifespans are typical figures for U.S. homes, in line with commonly cited industry ranges; costs are rough installed prices in 2026 dollars. Your manufacturer's manual and local conditions come first.
