In roll roofing, how many inches should endlaps be offset?

In roll roofing, it is essential to offset the endlaps by 6 inches to ensure proper water drainage and to minimize the risk of leaks. This offset creates a staggered pattern that helps to direct water away from the seams, as overlapping materials can help mitigate the potential for water intrusion. By adhering to this standard, the integrity of the roofing system is enhanced, contributing to its overall effectiveness and durability over time. Properly installing roll roofing with the correct endlap offset protects against possible damage from weather elements and extends the lifespan of the roof.
