It takes the same number of person-hours (12) to cover an average-sized (150m2), storm-damaged home with Stormseal or tarps.
Tarps leak, flap and fly-away, requiring frequent re-attachment or replacement. While householders wait for their insurance payout and permanent repairs, they call their insurers’ builders back to re-install tarps every three weeks, on average.
The first tarp installation to an entire home costs around $3,500 in labour and materials. Each re-installation costs around $800. Over a period of 3 months, initial tarp installation + 4 repeats cost around $6,700 or $45/m2*.
Superior Stormseal costs around $30/m2 or 33% less than tarps. Because Stormseal stays put and resists wind, rain and hail for at least a year, you only need to install it once.
But the real cost of tarps is far greater. Tarp failures cause additional property damage, adding many $thousands to each insurance claim. Leaking, flapping, fly-away tarps also cause immense suffering and frustration for residents who have to live under them for months.

*When a major storm damages many properties, householders often wait 6-12 months for permanent repairs, so this calculation is conservative.
