The Zone

Improper fastener placement is the leading cause of incorrect shingle installation and can subsequently void the warranty. Malarkey laminate shingles are manufactured with The Zone patented nailing area, which is over three times larger than other laminate shingles and dramatically improves correct fastener placement.

Double Rain Seal Protection

rain sealA rain seal helps hold shingles in place during high winds and protects against wind-blown rain entering beneath the shingles. Malarkey laminate shingles are manufactured with an extra line of defense in the critical area for laminated shingles, with double SEBS asphalt rain seals. Malarkey’s SEBS asphalt has adhesive properties to join the shingle together and cohesive properties to prevent it from separating. SEBS is also flexible down to 0F (-18C), ensuring the rain seal remains intact through freeze and thaw cycles.
