Underlayment & Fasteners

Underlayment & Fasteners

Ludowici roofs are crafted to last a lifetime and the underlayment and fasteners should be just as durable. Ludowici Pro 70 Underlayment provides superior roof deck coverage versus traditional felt underlayment. It does not curl or scuff and its rubberized asphalt content provides a more pliable membrane, proving itself to be less susceptible to damage during installation and saving on installation time by laying smoother. Ludowici Pro 70 does not decompose like felt, providing a much more stable and long lasting underlayment for your new Ludowici roof.
