If I recall correctly, there are also some roofs that the underlayment is failing, and the only remedy is to replace the entire roof. So, if you are having a problem with your roof contact your insurance company and discuss with them. If this is a material problem then the supplier of the roofing material should be covering the cost of replacement, if the roof has real weather damage, your insurance should be covering the cost, if your roof is old and worn out, you will be covering the cost.
