Here are some signs that your roof may need repair or replacement:

• Missing or damaged shingles. Shingles are the most common type of roofing material, and they can be damaged by wind, hail, or other weather events. If you see missing or damaged shingles, it’s a sign that your roof needs repair.
• Loose or cracked flashing. Flashing is a metal or plastic material that helps to seal the edges of your roof. If it’s loose or cracked, it can allow water to leak into your home.
• Wavy or sagging shingles. Wavy or sagging shingles are a sign that your roof may be overloaded with snow or ice. If the problem is severe, it may be necessary to replace your roof.
• Water damage. If you see water damage in your attic or on your ceilings, it’s a sign that your roof is leaking. Leaks can cause mold and mildew growth, which can damage your home’s structure and make it unhealthy to live in.
• Age. The average lifespan of a roof is 20-25 years. If your roof is older than this, it may be time to replace it, even if it doesn’t show any signs of damage.

If you notice any of these signs, it’s a good idea to have a qualified roofer inspect your roof to determine if it needs repair or replacement.

Here are some factors to consider when deciding whether to repair or replace your roof:

• The cost of repair versus replacement. Repairs can be less expensive than replacement, but they may not be as long-lasting.
• The severity of the damage. If the damage is extensive, it may be more cost-effective to replace your roof than to repair it.
• The age of your roof. If your roof is older than 20 years, it may be time to replace it, even if it doesn’t show any signs of damage.
• The type of roofing material. Some roofing materials, such as asphalt shingles, have a shorter lifespan than others, such as metal roofs.
• Your budget. The cost of a roof repair or replacement can vary depending on the size of your home, the type of roofing material, and the severity of the damage.

If you’re not sure whether to repair or replace your roof, it’s a good idea to get quotes from several qualified roofers. This will help you to compare prices and services and make an informed decision.
