What You Need To Know About Metal Roofs Before Installation

Metal roofing is becoming a viable option for many homeowners except those with flat roof pitches. Many people are attracted to this roofing option due to its durability and several other benefits. Metal roofs appeal to the eye, offer great strength, and can last for decades.

These roofs are ideal for locations where there is frequent snowfall. Also, such metal roofs can withstand windy conditions. They are easily distinguishable from traditional asphalt and shingle roofs. If you are considering investing in metal roofing, there are a few things that you must know before installing them. Continue reading this blog post to learn all the points you need to know about metal roofs before installing them.

You Can Install Metal Roofing Over An Existing Roof

Many people may think that metal roofing must be installed from the start, and you must remove your existing roof to install them. However, this is not true, as metal roofs can be installed over your existing roof without tearing off the shingles, provided that your local building code allows it. Although removing the shingles is the preferred road since caring for them can be messy and raise the cost of the process.

Moreover, water can build up inside these two roofs and cause mold and rot. Therefore, if possible, it is better to remove the existing roof and install the new one. Nevertheless, if removing the roof is leading to issues you can always install it over the existing one. It is better to consult with your roofing contractor and see what they suggest to you.

Metal Roofing Doesn’t Attract Lightning

Many homeowners have this misconception about metal roofs that it attracts lightning. However, these are just myths and do not increase the risk of a lightning strike. If we support this by a fact, the reason is that the lighting seeks a path to the ground. Metal roofs are isolated structures with no direct part to the ground, like trees, telephone poles, or other structures that attract lightning. Therefore, there is no probability of metal roofing attracting lightning, and you can install them without worry.

Metal Roofs Can Also Work On Roofs With Low Slopes

This is another common misconception among homeowners, as they often believe that metal roofing is only suitable for roofs with steep slopes. Metal roofing on low slopes is installed in large sheets with the seams raised and sealed tightly together to resist water. A bed of the slope is necessary to ensure that the water runs off so that there is no accumulation of water on the roof, which can cause moisture or mold.

Metal Roofs Are Recyclable

Metal roofs last for a very long time. They can function properly for about 15 to 20 years and are readily accepted at metal recycling outlets. On the other hand, if we think about old asphalt roofing, it is usually destined to take up space at a landfill.

Metal Roof Cost

Metal roofs might seem a bit expensive initially, but their longevity justifies their cost. A metal roof’s price will depend on the company and can range from $120 to $900 per 100 square feet. This price might seem a bit expensive initially and can cost up to 10 times the amount of asphalt shingle. Moreover, the labor might also be expensive if you hire a professional contractor. However, in this case, you will get what you pay for and won’t need to install or reconsider your roof again and again.


Your metal roofing contractor can suggest the best possible solutions, measures, materials, and styles for your metal roof. This is necessary so that the final product matches your budget, aesthetics, and expectations.
