This is what we do:

Our roofing story start to finish shows a typical Tar and Gravel plant or warehouse where we can take a Duro-Last PVC membrane and go right over the top saving money and offering up to a 20 year Warranty. No need to tear off the old roof (unless its saturated), no heavy disposal costs and environmental waste added to landfills.

• This is a typical Tar and Gravel built up roof system
• A steel deck, covered by a vapour barrier that is typically paper, some type of insulation, then four plies (layers) of paper and asphalt covered by a layer of asphalt and pea stone gravel. Hence your Tar and Gravel Built up Roof System.
• Step #1 Inspect the roof for wet insulation A test cut is made in the roof if moisture is suspected and the metal roof deck is inspected for degradation. Seen here is 2" of fiberglass insulation before the Tar and Gravel roof
• Step #2 If wet insulation is found it must be removed. If not go to Step #4 In a case where the insulation is saturated it must be removed but only the saturated sections
• Step #3 Replace with new insulation When the wet roofing is removed new insulation is installed to match the height of the old roof to begin the recover process
• Step #4 Install separation board Polystyrene separation board is laid to keep the old roof and new roof separated
