Expert Verdict — Reviewed by the SuperArbor Pro Desk
Hybrid underlayments like Lastobond ECO give you more durability than asphalt felt with less cost than full synthetic systems, and they are a sensible choice under standing seam metal and high-wind shingle jobs. Order by square, add roll laps per the data sheet, and keep rolls dry and shaded until install. For assemblies requiring a listed high-temperature underlayment, verify the Shield HT listing documents before submittal.
Membrane surfaces can be slippery, so wear proper footwear and fall protection when installing underlayment on pitched roofs.
Add Soprema Lastobond ECO underlayment rolls to your cart and protect the deck before the first shingle goes down.
