I never recommend a homeowner get on their roof, much less try to repair or replace it. If you don’t know what you are doing you can do much more damage to your roof and possibly to yourself.

The decision to repair or replace is a big one. The best way to prevent roof replacement is to keep it from becoming seriously damaged. Proper roof maintenance and yearly inspections by a professional can help prevent roof replacement. But if your roof is currently leaking, it’s best to have a professional inspection to determine the source of the leak. You then will know if it can be repaired or if it needs to be replaced.

This all depends on the current ventilation and insulation of the attic. If you have an older home, it might not be insulated or ventilated well enough for your current living conditions. A proper inspection can help you determine if you have adequate ventilation and insulation or if you need one or the other or both.
