To slope a flat roof for effective drainage, you can install tapered insulation or use crickets and saddles to create a slope towards the drains. This will help prevent water pooling and ensure proper drainage off the roof.
flat roofing is simply a flat roof structure, ie their is no slope in the roof, it is completely flat. For that reason it has to be super waterproof has rain will collect and stay on the roof.
The ideal slope for a porch roof is typically between 1/4 inch to 1/2 inch per foot. This slope helps with proper drainage of water and maintains the structural integrity of the roof.
The minimum slope required for roof drainage to ensure proper water flow is typically 1/4 inch per foot.

Roofs may be functionally flat or "pitched". In building construction, roof pitch is a numerical measure of the steepness of a roof. A flat roof on the otherhand, is a roof which is almost level in contrast to the many types of sloped roofs. The slope of a roof is properly known as its pitch and flat roofs have up to approximately 10°. If you have a flat roof, there is probably a leak in it or there will be a need for a flat roof repairs in the future.
The best way to install a downspout drainage pipe is to ensure it slopes away from the house, has a solid foundation, and is connected to a proper drainage system to effectively manage rainwater runoff from the roof.
Rubber roofs aren't supposed to be entirely flat. They should have a slight slope towards a drain or towards the edge. I would wait until you get some leakage, than tear up and reconfigure the "slight slope" to permanently correct the problem. Modern rubber roofs usually have a foam board underlayment. If you can find a supplier, I believe you can order these sheets of foam designed specifically for your roof. These sheets will be graduated in different thicknesses and numbered to be applied in a specific order to obtain the proper slope for drainage on your particular roof.
It all depends on the type of existing roofing that is going to be demolished and the replacment with a deck. If the roof is flat it is cheaper but if the roof has a slope then a whole new flat roof is required to support the deck.
My roofer asked me what the slope of the roof was. It was an 8,12. That meant that the rise was 8 inches for 12 inches of run. A steeper roof would have more area and a flat roof would have less.At the corner I have to cut a 45 degree angle to make it match. That is a slope when turned flat of 1 over 1.The ramps in the USA have to be flatter than a slope of 1 over 10 and recommended to 1 over 12.
To repair a flat roof effectively and efficiently, start by identifying the source of the leak. Clean the area thoroughly and apply a patch or sealant specifically designed for flat roofs. Ensure the repair is done properly to prevent future leaks. Regular maintenance and inspections can help prolong the life of the roof.
The best maintenance tips for a low slope metal roof are to regularly inspect for damage, clean debris and dirt, ensure proper drainage, and address any issues promptly to prevent rust and leaks.
