Raul Arellano, co-founder, has been involved in the roofing industry since 1997. Raul grew up in South Texas and has traveled the United States managing roofing crews. Raul started in the field and quickly was promoted because of his leadership of people and his ability to get a roof in on time and on budget. In his “off time”, which is rare, Raul can be found on a soccer field, or with his twin boys and his wife Jessica. The boys attend College Station High School where Jessica is a Spanish teacher.
