Flat Roof Gravel Size

We need to top up the gravel in one spot on our flat tar and gravel roof.

Flat roof gravel size.

It was installed 12 years ago when this section of the house was added over the garage and some first story rooms. He told me that i needed to lay some gravel on the flat roof. We recently had the building regs inspector around to sign off the extension we have had built. Are there any specific requirements for the gravel size type colour etc that we should keep in mind when we re buying a bag.

Email save comment 2. It can be difficult to work with as it generally cannot be shoveled and instead must be moved individually stone by stone. Gravel to protect built up. Ft that is currently covered with tar and gravel.

Typically this gravel ranges in diameter from 2 5 inches 6 35 centimeters to 4 inches 10 16 centimeters. There are different types and weights of gravel used on flat roofs for these purposes. To protect the underlying layer of roofing materials as is the case with built up roofs burs. To weigh down or secure the roofing material as is the case with single ply flat roofs.

Gravel known as size 1 is relatively large. Can i use pea shingle size 10 15mm does anyone know what sort of area one of the bags from a diy store would approx cover.
