7 Things to Know About Metal Roofing

According to the 2020 Dodge Report, the demand for metal roofing has significantly risen in the past years and is expected to keep growing. This has largely been propelled by the ability of these roofs to perform even in the most demanding environments, plus many other benefits.

As a homeowner considering this roofing option, here are seven things to know about metal roofing.

1.   Metal roofs can be installed on existing roofs

Since metal roofs are one of the lightest roofing materials, installing them on existing roofs is possible, provided the local building codes in your area allow it. However, to succeed in this type of installation, you must first learn how to install metal roofing or hire professionals.

This way, you will avoid potential problems such as trapped water vapor that occurs when there is moisture build-up between your old roof and the metal roof.

2.   Metal roofs are not noisy

Unlike common presumptions, metal roofs are no noisier than any other type of roofing when rain or hail falls on them. Typically, metal roofing is done over a solid substrate, which, together with the loft and insulation, provides an excellent sound barrier.

3.   Metal roofs do not attract lightning

Another common misconception about metal roofing that the Metal Construction Association has dispelled is that they attract lightning. This is not true as a metal roof is a non-combustible material and an electric conductor; hence it does not provide any risk during a lightning event.

4.   Metal roofs can withstand strong winds and hurricanes

Metal roofs have superior resistance to extreme weather conditions, making them a viable choice if you live in an area prone to strong winds and hurricanes. Tests done by Underwriters Laboratory (UL) show that most metal roofs can withstand gusts of up to 140 miles per hour, which is equivalent to a category four hurricane.

5.   Metal roofs are energy efficient

Since metal roofs are good at reflecting solar radiant heat, they are incredibly energy-efficient. If you live in a hot region, you can further reduce your cooling costs by applying a granular or shiny coating on your metal roof.

6.   Metal roofs offer astounding long-term value

Whether you are building your first home or renovating your old property, it is critical to invest in a roof that will last for decades, and metal roofing does live up to expectations since:

  • Metal roofs can last for over forty years, giving you the time value of your investment.
  • Metal roofs are impervious to rot and insect damage
  • Metal roofs are not easily damaged by fire

7.   Metal roofing works on roofs with low slopes

Metal roofing is not only suitable for roofs with a steep slope but can also work fine on a roof with low slopes. This makes them an excellent option for most homes as long as there is some gentle slope for water run-off.
