Tarps are temporary. The blue polyethylene tarp on most South Florida roofs after a named storm starts degrading in UV within 72 hours and fails within 3 to 6 weeks. Tarps that stay on longer create three secondary problems.
Problem 1: UV degradation
Florida sun breaks polyethylene chemical bonds. A new tarp at week 1 is waterproof. The same tarp at week 5 has hairline cracks across the surface and lets water through faster than the original leak.
Problem 2: Fastener damage
Tarps attach via nails and battens. Every nail is a new penetration in the existing roof system. If the nails go through good underlayment, you have created six to twelve new leak points where there were none.
Problem 3: Ponding water
A tarp without proper drainage holds rainwater. The standing water adds 5-15 pounds per square foot to the roof load. On an already-compromised structure, this is a real failure risk.
What to do instead
For a real storm response: tarp service from a licensed roofing contractor lasts 2-3 weeks at most. Within that window, you need a permanent repair scheduled, even if your insurance claim is still in review.
Perkins tarp service is dispatched within 24 hours during named-storm season. The tarp goes on with non-penetrating attachment where possible, with drainage routed to existing gutters, and with a written timeline for the permanent repair.
