TruLo® Lo Odor Asphalt takes the most annoying odor out of every hot asphalt job. Maybe that's why it's now the industry standard that other roofing products are measured against. And it measures up - when compared to leading competitive low-odor asphalts and additives, TruLo® Lo Odor asphalt was 45% more effective at reducing odor-causing compounds. All of these product advances help you avoid costly, odor-borne scheduling issues like night and weekend work.
