A total roof collapse or tear off is one of the most expensive roof damages you can ever face because it means you have to replace the whole roof. That is why you need to do everything possible to prevent such damages, and the following measures can help.
Take Prompt Care Of Roof Damages
Properly maintained roofs, especially those that are relatively new, rarely collapse. In most cases, it is the poorly maintained ones that collapse during a storm. For example, if you have ignored a few missing shingles on the edge of your roof, it may give wind the access it needs to tear into your roof and rip it off.
Keep Your Roof Free Of Snow
By far, snow accumulation is the biggest risk of roof collapse. This is because snow is relatively heavy, and roofs aren't constructed to handle endless loads of snow. Therefore, put measures in place to allow snow to melt and flow off the roof; for example, install heating systems on the edges of the roof to prevent ice dams. In case snow does accumulate on the roof, rake it off as soon as possible before it causes damage.
Be Careful With Shingle Layering
In some jurisdictions, it's legal to install a shingle roof on top of an old shingle layer without removing the existing layer. While this may save you the money you would have used for the teardown, it's not exactly a safe process. This is because the weight of two shingle layers may overwhelm roof support structures and cause a collapse. Therefore, before layering shingles, ensure that the roof support system is strong enough to handle it.
Be Careful with Load Creep
As previously mentioned, having too much weight on the roof is one of the most obvious ways to cause a roof collapse. However, snow accumulation isn't the only way your roof can be overloaded, even human activity and accumulation can overload the roof. Load creep is where you increase the overall load on your roof bit by bit, maybe over the course of several years, until it becomes too much. For example, you may install rooftop HVAC systems, add communication antennas, construct roof gardens, and so on and so forth. Be careful with what goes on your roof if you don't want load creep to cause a roof crash.
Regular inspection and maintenance of your roof should help you prevent a total collapse. Consult a roofing contractor for a relevant maintenance schedule.

If your roof does collapse and you need a replacement, take your time to identify an experienced roofing contractor that will ensure the new roof is properly installed.
