I am looking or the correct terminology of the roofing used on many low slope roofs here in Florida.
I have watched it installed numerous times. They start with a double layer of 15# roofing felt and then hot mop what appears to be 90# mineral surface roll roofing over it. Typically they will apply the hot tar and lay the first layer even with the eaves, place the second layer over it to align it with an exposure of about 18", and fold it down. They mop the area under where the top of the strip will go with tar, lay it back down and fold the lower part back over the top. They then mop the underside of that layer and lay it back down to seal on the layer below. The better roofers will sprinkle matching granules over any tar that is exposed.
What is the correct name for this type of roof?
