The rubber material that the membrane is made of is called Bitumen. Bitumen and Asphalt are interchangeable words for the same product. When we refer to a rubber roof then we are referring to a material that comes from Asphalt and has been modified, hence the word Modified Bitumen Membrane. This is what gives it the rubberish properties. To understand more read this article about Bitumen

What is the best way to do a roof?

1.To strip the old roofing material and install a new rubber membrane or

2. To install over an existing roofing surface.

The answer is: If the existing roofing surface is in a relatively good condition, meaning there is no rotten plywood or decking, the surface is not crumbling or soft, then it’s almost best to go over an existing roofing surface. This is a big time saver and cost as well. Many times the existing roofing adds a added insulation.

There are three main types of drains on a flat roof. Scuppers, gutters and inner drains. It is important to make sure that water can drain off a roof. Water ponding on a roof is not necessarily bad, but the debris that collects in those areas causes the material to deteriorate. It is good policy to keep a roof clean of leaves and twigs.

The easiest way to keep a roof clean is to use a hand blower. It only takes a few minutes every two weeks to blow off debris. This way the drains are kept clean and eliminates the possibility of flooding a roof due to a blocked drain. Part of maintenance of a roof is to make sure that the drains are cleared from debris.

Inner drains are commonly known as a drain that’s somewhere in the middle of the roof. They require high maintenance because all the debris on the roof tends to block the strainer easily. The easiest way to overcome this strainer problem is to install a self-made improved strainer.

This video explains about a perfect Inner drain. This is how drains are supposed to be installed.

Scuppers are the drains on an edge of a roof. Water is funneled to one are where it can spill into a leader or gutter. Scuppers are easier to maintain than inner drains because for the most of the time the debris gets washed out, whereas inner drains have strainers that get clogged with debris easily.

This video shows the repair of a scupper and also the roof around it.
