Is there anyone here that is familiar with a built up roof using an Elvaloy(brand name) top. I am working with a job where the roof is showing significant cracking of the elvaloy material. The roof architect claims it is hail damage. Some are concentric circles, however, very large circles. There are not corresponding damages to the vent caps, or metal flashing to indicate hail. Is there any information available regarding defects in this elvaloy materials. I am getting alot of push back from the insurance adjuster regarding the replacement of the roof.
