The high winds tore the roof off a house on Seaforth Rd in Waihi Beach.
Louisa Duckmanton, who has lived in the house around 30 years, was woken about 4am.
"I heard a big bang and thought it was the deck - I looked out of the (front) window and the deck was gone - but when I looked out the back there was all this pink stuff," she said.
The "pink stuff" was the roof insulation and the roof itself had been dumped in a neighbouring paddock.
Wild weather has wrecked havoc throughout the region but forecasters warn the worst could still come later today.
