Does anyone have feedback on using this product? I was trying to decide on using this underlayment or Safeguard30. I’m wondering if the Safeguard is the better product since it might have some breathing ability
What type of roofing is going over it and is the roof deck ventilated?
I will be installing Asphalt shingles with a ridge Vent
Any of the synthetics will be fine as breathability of the underlayment is inconsequential over a vented roof deck.
