If the damage to your roof is minor or contained to one spot, it may make more sense to repair than replace it, especially if the roof is relatively new. Consider your warranty, homeowners insurance, and roof age. If the roof is nearing the end of its expected lifespan, it may be more cost-effective to replace it.
How long a roof lasts before needing repairs depends on its type and maintenance level. Copper, tile, and slate roofs can last more than 50 years, and metal roofs can last even longer. Asphalt shingles and wood shake roofs last between 20 and 30 years and are more likely to need repairs during that time.
Water dripping into your home through the ceiling is the most obvious sign of a leaky roof, but there are other warning signs to watch for before it gets to that. Common signs of a roof leak include water spots on your ceiling or walls and missing shingles outside. Check your metal flashing and boot cover—if they’re in bad shape, they may allow for a leak.
