If your roof is damaged or has leaked, then your decking may need to be replaced. Replacing or repairing roof decking will cost between $2.20 and $3.00 per square foot.

So, if your shingles crack and water gets through them, the water will hit the underlayment and wont rot your entire roofing system. Most underlayment materials used today are made with a synthetic felt that is then covered in asphalt.

In many places, underlayment is required for your home to be up to code and must be replaced as part of your roof replacement. New underlayment costs between $1.50 and $2.10 per square foot.
