Zinc is the greenest of the materials due to its low melting point, but is also very expensive. Aluminum offers a great solution in coastal regions, and is less expensive than Copper or Zinc. Steel is the most used of the materials, making it less expensive and affordable as a metal roofing option for homeowners as well as commercial builds. Use a wire brush to abrade the surface to promote paint adhesion. Do this by scratching the wire brush against the aluminum flashing in a circular, counter-clockwise motion. Brass is very reactive with aluminum, and brass screws will cause substantial corrosion of an aluminum base metal in a wet environment. The process of galvanic corrosion depends on the presence of an electrolyte, though, so in a totally dry environment the risk of corrosion is low, even if . There are projects where the look and feel of metal roofing is the best solution. There are multiple types of metal roof panels ranging from metal roof shingles to standing seam metal panels. The best application is different for each project and building. Metal Valleys on Roof Are the Best Option. That center point (only about 1 inch high) actually minimizes the wash effect of a larger surface area hitting the valley and washing up the adjacent roofline. In advance, I'm thanking you for your consideration. Happy fall! -- Fairfax, liethemdenixi.gq: Henri de Marne.

Metal Roof Repair Solutions: How to Solve Your Leaking Metal Roof Problems
When considering galvanized flashing , you need to make a choice between aluminum versus steel. The use of aluminum, a lightweight material, versus a heavier steel galvanized flashing depends on your budget, the conditions under which the flashing will be exposed to and whether you believe that one material is a better quality flashing for your home than the other. These considerations will drive your decision to use either aluminum flashing or steel flashing.
Aluminum flashing for roofs is one of the 3 rust resistant materials used in flashing, along with steel and copper. Aluminum flashing is popular with do-it-yourselfers when they choose to install a roof flashing, because of its flexibility and ease to work with.
It is easier for a non-professional installer to bend and manipulate aluminum than it is to bend and manipulate steel. It is a mid-ranged metal flashing material and it holds its shape well.
Galvanized Flashing: Aluminum vs Steel
Steel flashing is another type of metal roof flashing that is found in roof constructions. It is the lowest costing material that is used in roof flashing. Galvanized steel flashing is created by coating metal with a galvanized steel coating, which lends to its lower cost than either aluminum or copper.
