I strongly believe that the key to a healthy house is the regular inspection of the roof. This is where all problems start. A minor leak can easily pass unnoticed, thus creating a good environment for mold growths.
By the time you notice the problem, it's possible that children in your household have already got sick, the doctors not being able to find the cause of their health issues.
As the damage gets bigger, you may notice water on the attic floor. This is the moment when you are going to think about contacting a roofing company specialist to come and see what can be done to repair your roof. Such repairs can be quite expensive, so you should be prepared to pay the price of your procrastination.
On the other hand, people who want to save money on house repairs are going t hire a good residential roofing maintenance and repair company right off the bat. They are going to conduct periodical inspections in order to make sure even the smallest leak is detected before it becomes a real problem. Fixing small problems is always cheaper than having to patch a huge hole in the roof, so try not to get to that point.
