What You Need To Consider When Installing a Metal Roof

Metal roofs are often the most affordable type of roofing material. This is because metal materials are very durable, and they last for a long time. If you install a metal roof on your home, you may never have to replace it again. A lot of people don’t know this though. They think that they need to keep replacing their old roofs with new ones every few years or so. But when in reality, installing a metal roof can be much more cost-effective in the long run than any other type of roofing material.

What Is A Metal Roof?

Metal roofs are made from steel or sheet metal. They are installed over the existing roofing material of a house, providing protection from the sun and rain in a similar way to asphalt shingles.

How to Install Metal Roofing?

You will need some special tools for this project, such as a roofing calculator, metal sheathing, metal flashing, and a ladder. For installing the metal roofing here are some easy steps:

  1. First of all, you will need to know the total square footage of your roof and also purchase the amount of metal roofing needed.
  2. Next, measure and cut out a piece for each side of your house and at least one piece over the peak of your home’s peaks. This piece is called a starter strip.
  3. You will then need to remove the shingles from your roof. Usually, you can use a flat bar to pry them off by sliding them along the edge of each course of shingles.
  4. You will now secure your metal sheets on top of your home using either rubber or neoprene sealant.
  5. To ensure a watertight seal it is recommended that you overlap each sheet by 3 inches. You can do this by slipping the end of one sheet into another at an angle and then fastening them together with roofing nails once they are in place.
  6. The final step is to add your starter strip and then your side sheets on your roof. At this point, all that’s left is to nail the panels into place and seal them with an additional sealant so that no water can get underneath them and cause damage.
