Nowadays, people all over the world are breaking the conventional barriers and are using metal roofs confidently. Conventionally, metal roofs are not used because of the noise they produce in bad weather conditions. However, the irritating noise can be dealt with proper insulation. Insulation also increases the efficiency of the metal roof. The materials used for building metal roofs are copper, aluminum or steel. These are installed in the form of panels.

Use plywood or oriented strand boards to cover the roof. Fix plywood boards to the roof with galvanized nails as they are not prone to rust. Always install the plywood boards in perpendicular direction to the beams.

Now, cover the plywood or oriented board sheathing with the building paper. It would ensure the safety of sheathing from moisture and leaks. Overlap the sheathing papers at least six inches and glue them together to the sheathing with steel nails or stapler.

Now, move on to rigid foam insulation and put the sheets of rigid foam all over the roof. Install them closely together but do not overlap them.

Cover the seams of the insulation sheets with the help of a duct tape. Duct tape helps in preventing the air and water leaks. In addition, it will also boost the insulating effectiveness of the roof by preventing air leak.

In case you are trying to insulate an existing roof, you first have to inspect your roof. Enter your attic area and locate a sheathing of plywood or oriented strand board installed at the base of the structure. Horizontal supporting parts are purloins and the larger angled beams are known as joists.

Fit fiberglass bats into the gaps between purloins and plywood. Fitting the fiberglass bats too tightly can diminish the effectiveness of the fiberglass insulation.

You can use rigid foam insulation if the gaps between the joists and plywood boards or (sheathing) are wider. First of all, cut the sheets of insulation into suitable sizes and then put them into place and fix them using adhesive or staple. Do not use nails for fixing work as nails can perforate the insulation sheets which in turn results in leaks.
