What type of shingles are most recommended for coastal and hurricane-prone areas in Florida?

What is the importance of tin caps in shingle installation in Miami?

Tin caps, like our 1-5/8″ Hot Dipped Roofing Tin Caps, are fundamental for secure fastening of shingles and underlayment. They increase the fastening surface of the nail, distributing the load evenly and minimizing the risk of material tearing, which is crucial for roof resistance to strong winds.

What roofing building code governs in Miami-Dade for 2025?

What role do Asoflex SBS and Poly IRX play in roof durability in tropical climates?

Asoflex SBS is a perimeter membrane that hermetically seals against wind intrusion, while Poly IRX is a synthetic underlayment that acts as a moisture barrier. Both are essential in tropical climates to prevent leaks and water damage.

Why is the special nailing pattern important for hurricane resistance?

A special nailing pattern, such as using six nails per shingle instead of four, maximizes wind resistance. This manufacturer-certified method helps shingles remain attached to the roof even during intense wind gusts, protecting against roof covering detachment.

What type of maintenance is required to extend the life of a shingle roof in Miami?
