Roof replacement timing varies significantly based on your roofing material and local climate conditions. In Florida, asphalt shingle roofs typically need replacement every 15-25 years, while metal roofs can last 40-70 years, and tile roofs often reach 50+ years with proper underlayment maintenance. Rather than focusing solely on age, watch for warning signs like missing or curling shingles, granule loss, leaks, or sagging sections. Having your roof professionally inspected after major storms and annually helps identify when replacement makes more sense than continued repairs. Planning ahead for this significant investment ensures you’re not caught off guard by unexpected failure.
