Flat Roof Polyurethane Insulation and Felt Waterproofing

Why are the insulation sheets not fixed? If there's any wind suction, they'll lift straight up

It takes over 6,000 nails to properly secure a roof. Even one out of place can lead to leaks or void a wind warranty. That’s why we patented the industry’s first larger nailing area, called The Zone®. #FeatureFriday #Weatherproof @Holcim

not safe at all in case of fire...

Protects from leaks & water damage

Sure

Never seen them use foam blocks like that. Probably great insulation

Looks like a fire hazard

A few notes: - insulation is Polyisocyanurate - insulation was not mechanically fastened or adhered (no wind uplift resistance) - no protection board over insulation prior to 1st layer of membrane (1st layer of membrane loose laid? - only one layer of membrane flashing at parapet and does not go up and over parapet (parapet not sloped to roof) - no UV protection on 2nd membrane layer Good technique installing membrane flashing (applied heat and pressure throughout and ensured bleed at seams)

Why damaging the blocks, what an amateur !

I thought that was Giant Tiramisu 😭

where is the foam between the blocks?
