| Do you mean if you have a leak? Your homeowner's insurance only covers "sudden perils" which means in general slow leaks are not covered.
If your roof leaks suddenly due to say, heavy rains and damages your flooring, then yes your insurance will cover this.
But if say due to improper installation you have a leak over several months that causes mold, then there is no coverage provided.
One thing to keep in mind is that as a homeowner you are responsible for regular maintenance of your home so if you incur a loss due to improper installation, then insurance will not likely cover this. If it were the case that a professional installer did sub-par workmanship, then they would be responsible for the resulting damages.
Assuming, since you are asking this question, that you know how to install a roof, then that in no way 'voids' your insurance. As long as the job is done properly, then you won't run into any problems insurance-wise. You just won't have the added protection of a professional guarantee of the craftmanship. |
