Has anyone on here used these rubber boots for flashing. I have a shop that we are installing a free standing wood stove in it. It has corrugated galvanized one piece panels,as in one piece of tin front to back. I have the standard roof jack flashing that people use with shingle roofs. I know there is also a moldable aluminum flashing that can be formed for seal. I came across these rubber boots that go around the outside of class a pipe. I want to see if anyone on here as used them and what the feedback was before using it. My roof is flat enough im afraid rain will blow in under the moldable flashing and thought the boot would work better. I found a good price at pipebootexpress, so if ayone has used that brand let me know,thanks
