Plan the repair after the immediate emergency
Emergency damage control is not the same as diagnosing and repairing the roof. Wait until conditions are safe, locate the actual entry point and assess the surrounding roof and deck.
If the cause is an appropriate localised defect, the SealForge Kit provides a reinforced local repair system. Do not climb onto a wet, icy, fragile or otherwise unsafe roof, and seek professional help for widespread damage or an uncertain source.
