Do you believe that your roof should be replaced but you are not sure? You have already asked a roofing contractor and although he recommends you to replace the roof you are wondering if you can postpone this expenditure for some time? The rule of thumb is to repair when you can and replace when you must.

Here are the general guidelines to be taken into the account in making your decision:

Repair the roof

  • After wind damage
  • After harsh winter
  • If experience dark spots or blisters on ceilings
  • Signs of water leaks and damage are seen
  • Ice dams form on the roof
  • Icicles form at the edge of the roof
  • Feel rot and mildew smell coming to the home, especially in the summer
  • If answer is yes to any of the question in the 20 point roof inspection check list

Replace the roof

Typically the roof should be replaced if 1/3 of it is damaged, namely one third of the shingles are either cracked, curled, missing or have bare spots.

Additional and sure signs indicating that your roof must be replaced:

  • Water leaking in interior after rainstorm
  • Interior water damage such as ceiling dark spots and blisters
  • Signs of water damage in your attic such as mold, packed and damaged insulation, rotten structure
  • Sagging and rotten roof boards and peaks
  • Signs of algae buildup or bare looking shingles
  • Water damage in sheathing and soffits
  • Increased heating costs due to damaged attic insulation


Getting into the habit of regularly inspecting your roof may save you thousand of dollars in preventable repairs.
