A roofing square is 100 square feet of materials.
make sure the roof structure is sound and no moister damage. then it depends on what type of decking
Roof decking, exterior sheathing.
The answer depends on the width of the decking.
If you are looking for radiant barrier by the square foot just search online for radiant barrier. I install radiant barrier and it comes from www.ecofoil.com
A building that is framed with wood or light gauge metal with roof supports and decking that are the wood or light gauge metal are considered frame. The exterior can consist of any number of things from vinyl or wood siding, brick veneer or stucco.Joisted Masonry will mostly be a combination of solid brick (not brick veneer) or concrete block with wood or light gauge metal roofing supports and decking.

Roofing is usually sold and installed on a per square basis. A square is generally accepted as 100 square feet of coverage.
The answer will depend on the width of the decking boards.
Yes as long as there is nothing wrong with the old decking like rot or something of the sort. Make sure when you fasten it to hit the rafter with your nails or screws. I always separate the two layers of wood with tar paper also any time i lay over other wood.
You need to know the width (in metres) of the decking. Then Linear (or lineal) Metres * Width = Square metres so Linear Metres = Square Metrage / Width
You measure the roof to get the square feet. There are 100 square feet in a square. On a straight single peak roof it's height times length on one side and double it. Then divide the total square feet by 100. This final number will give you the number of squares you have. If the roof is a flat, commercial roof, it is the same (100 sq. ft = 1 SQ). However, if it is a metal panel commercial roof, you need to add in "stretch factor" or the added amount of square footage if the panels were to be stretched flat. A good estimate for this is: If the ribs on the metal panel are 1" tall, add 10% to your square footage; if the ribs are 1.5" tall, add 15% to your total square footage. So, if you have a metal roof that is an R-panel (_/-\_), the ribs are 1.5" tall and the roof is 100 SQ (or 10,000 sq ft), take 10,000 sq ft + 15% (1500) = 11,500 sq ft (115 Squares).
A metal roof will last longer than an asphalt roof. The cost range for a metal roof is about $350.00 to $650.00 per square of metal. However, each tile of asphalt roof would cost around $20 plus installation.
