What Causes Roofs to Collapse?


The roof is the cornerstone of homes and buildings. They are structurally built to protect everything inside, from your belongings to your family.

When a roof fails to maintain its structure, it is always with reason. Many things can cause a roof to collapse.

Too Much Weight

Snow and heavy rain can weaken your roof. Couple this with heavy decorative holiday items and you have a recipe for disaster. Too much weight can cause pressure on the roof, and it will begin to sag.

Heavy Snowfall

Snow is pretty and fun to play in. However, too much of it can cause massive damage to your roof. Signs that the roof is in distress during a snowstorm include:

  • Sudden creaking sounds
  • Doors struggling to open or close
  • Water stains appearing on the roof
  • The creation of ice dams
  • Doors opening on their own

If, for any reason, you begin to hear and see your windows crack, it is a sure sign that the building is unsafe. You should evacuate immediately.

The Age of the Roof

As your house ages, so does your roof. When you don't replace the roof, the elements will eventually cause it to collapse. The best way to prevent a full collapse is to know the lifespan of your roof and signs of it failing so you can get it replaced when needed. Having a professional inspect it annually will make this more simpler because they know what to look for and what to do.

Natural Disasters

If you live in tornado valley or in a hurricane hideaway, then your roof faces extra danger. You can prepare it to best severe weather by:

  • Securing the shingles with hurricane or tornado clips.
  • Installing wind resistant shingles.
  • Replacing the doors and windows with new wind and impact resistant ones. This will prevent the house or building from pressurizing, stopping the roof from ripping off or collapsing.

The Bottom Line

The biggest cause of a roof collapse is human error. It's easy to overlook telltale signs of a less than ideal roof, such as:

  • Drooping or sagging
  • Water leaks
  • Shingle granules inside of the gutter
  • Missing shingles
  • Curling or cupping of the shingles
  • Bald spots or broken shingles

Inspecting various areas of your home can help you to determine if your roof is becoming a severe issue. Taking preventive measures will help you avoid a roof collapse and a costly repair.

The best way to prevent a roof from collapsing is by simply taking care of it. Getting the roof inspected regularly by a professional, such as Can-Tech Roofing Ltd, will save you a headache, a potentially fatal accident, and money.

does a roofing contractor do more than roofing?

What all can a roofing company do for your home? Do roofers offer services other than roofing repair and installation? Would this be the contractor that you would call if you needed new gutters or fascia installed? How much would each of these services cost you? Having just remodeled a home from top to bottom, I have learned that there are some contractors that specialize in one service, but others that perform several different services on the home. Are you planning some big projects around your home? Visit my website to learn how I saved on labor costs by hiring a roofing contractor that did more than just roofing.
