hired a company to replace soffits(vinyl) and facia and gutters on large barn. current soffit was done with particle board rotting facia boards were to be replaced. i assumed the old soffit would be removed i don't know if this would be correct. then found installers placing vents over particle board not cutting holes for vents. when questioned they said they would drill holes. they used 1/4-3/8 drill bit putting 4-5 holes in area. this does not seem adaquate for ventilation to me, i would think these holes could easily plug and should be cut out. also caught them wrapping rotted boards with aluminum. am i over concerned or should i be doing something about this insisting that which is done be taken down and redone. would appreciate any advice anyone could give.
