Thank you for your interest in Pergo. Installing over a rough concrete surface is less an issue than your statement that this is an enclosed porch. Key to a successful installation is that the subfloor must be flat within 3/16” over a 10 ft. span or it requires that a leveler be applied or peaks sanded to gain that requirement. Secondly, the floor should not slope greater than 1” over a 6’ radius. Last, laminate and specifically the wood core will expand and contract with changes of humidity and temperature, which is why the requirement for indoor installation is that the room be climate controlled between 35-65% RH and 60-85° F.
