Why Underlayment Matters

In this AskARoofer™ Minisode, roofing expert John Kenney of Cotney Consulting Group answers a homeowner question about reroofing an aging asphalt shingle roof. Ann from California asked whether underlayment is necessary or if new shingles can go directly over the existing roof. John breaks down the difference between a full tear-off and a roof-over, explains why underlayment matters and outlines the long-term tradeoffs homeowners should understand before making a decision. The episode offers clear guidance for homeowners planning a reroof and looking to balance cost, performance and peace of mind.
