The majority of commercial and residential metal roofing is made of steel. Metal roofing materials are of considerably lighter weight when compared to their asphalt shingle counterparts. When considering metal roofing or asphalt shingles, be aware what exactly you are planning to invest in. It is wise to invest in the right roof for your chosen property.
When it boils down to steel roofing or asphalt shingles, it pays to know the differences between the two before choosing. Be aware that both materials are both suitable for roofing material; it just depends on what your preferences are and what is best for your property.
Here are some facts about metal roofing and asphalt shingles:
Metal Roofing
Pros
- Has more strength than asphalt. Metal roofing can withstand high winds and would be suitable in areas more susceptible to hurricanes.
- More fire resistant WITHOUT any proper underlayment and sheathing.
- Can retain heat. Metal would be the optimal choice for those who live in colder climates.
- With the added benefits of strength; it can be used for housing that requires a lot of roofing materials.
Cons
- The metal is a ferrous metal, meaning it cannot be guaranteed that it will never rust over time. However, this can be prevented if a protective barrier is put on both sides of the sheet(s).
- It is more susceptible to seawater damage over time. This is only dependent on the location of your building.
Asphalt Shingles
Pros
- Is sold at a lower cost than metal roofing.
- One of the easiest roofing products to install.
- Easier to repair.
Cons
- It is more susceptive to severe weather, such as severe winds and hail.
- If asphalt roofs do not get adequate sunlight exposure, they can be vulnerable to moss, mildew, and algae, which can shorten its lifespan.
- It is a durable roofing material but does not last as long as metal roofing, putting its longevity into question.
- Asphalt shingles are heavier than metal roofing, weighing at approximately 200 pounds per square.
- It is not as recyclable as metal roofing, with shingle waste making up the majority of building-related waste.
The type of roofing you choose will largely depend on your personal preference, as well as the location of your home. If your property is close to the ocean or the sea, the best choice would be asphalt since it is more resistant to saltwater corrosion. If you’re in a forested area that is prone to bushfires, then metal would be the better option as it is more fire resistant.
Regardless of what material type you choose for your roofing, both metal and asphalt are durable, although metal roofing does have a longer lifespan than their asphalt counterparts, and are also more environmentally sustainable, cost-effective in the long run and have better strength.
