Over the past few years, metal roofs have become increasingly popular, as they are known for their contemporary design, durability, and longevity. But although they provide a lot of advantages, they are not ideal for every household and budget.
It is important for you to have an understanding of the drawbacks of metal roofs as you contemplate a big investment in your exterior. In this guide by Blanchett Roofing & Construction, we’ll be looking at the realistic concerns you may have before you make the decision.
Basics of Metal Roofing
Metal roof pros and cons are the first considerations for homeowners when they start looking for new roofing materials; the advantages include:
- Fire resistance.
- 50-year lifespan.
- Excellent thermal and solar energy efficiency.
This can be very appealing to anybody who is searching for a lasting roofing choice.
But a thorough review of this material needs to take into account the drawbacks to metal roofs. There is no perfect fit for any climate or budget when it comes to building materials. This should help you not get surprised with additional expenses or slowdown in performance.
Knowing the Common Mistakes and Problems with Metal Roofing
The more you research the topic, the more issues you will encounter with metal roofing that will impact your comfort and maintenance.
The Noise Factor:
One of the most common issues with metal roofs is sound transmission. In the event of a heavy rainstorm or hailstorm, a metal roof can be much louder than traditional asphalt shingles.
Adding additional attic insulation will easily muffle this noise, but it’s an additional step and expense you’ll have to think about.
Expansion and Contraction:
When metal is hot, it expands; when it is cold, it contracts. However, if the roof panels are not fastened to the building with special attachments designed to accommodate movement, the panels will wave, buckle, or eventually work loose with time.
Denting and Scratching:
Metal tends to be very hard and can resist denting even if hit by large hail, but soft metals such as aluminum and copper may create this issue if tree branches fall on the house.
Identifying these problems with metal roofing will enable you to address the preventive measures that will be required at the installation time.
High Initial Cost:
Unlike asphalt shingles, metal roof panels are expensive. This means you have to pay a higher initial cost at the time of installation.
Making Your Final Roofing Choice
Of course, for most homeowners, the initial expense is the final determining factor when they are ready to select the roofing material they want to use.
Metal roofing is more costly than regular asphalt shingles, and can cost two to three times as much as materials and trained personnel. This is a large upfront cost, but one that is well worth it in the long term if you are looking to live in your home for many, many years.
However, if you are considering moving anywhere in the next few years, you will probably never get your money back, and it’s not particularly financially wise.
It is important to hire a certified, experienced metal roofing contractor, not a general handyman, in order to prevent possible installation mistakes which can cause leaks or buckling.
Conclusion
Metal roofs will last a very long time and provide a modern appearance, but they have certain drawbacks such as initial cost, noise, and denting. These are all the drawbacks of metal roofs you should know about in advance so that you can determine whether the benefits in the long run are worth the drawbacks in the short term for your house.
Frequently Asked Questions
Do metal roofs attract lightning?
No. A metal roof does not increase your house’s chances of being struck by lightning.
If you have a metal roof over your home, would you be able to walk on it safely?
Yes, but you’ll need to be careful. Soft-soled shoes are required, and one must step directly on the roof structure where the panels are located below. They can be dented or scratched if not walked on properly.
Do metal roofs have a lifespan?
Metal roofing can last up to 50 years. Today’s metal roofing is coated with a protective material that prevents rust from occurring, such as zinc or special paint.
Will a metal roof make my home warmer in the summer?
No. Metal will reflect the solar radiant heat away from your home, rather than absorbing it like the dark asphalt shingles; that fact will help to reduce your summer cooling cost.
Is repairing a broken panel of metal roof difficult?
Can be tricky and costly. Since the metal roofs are constructed with large, interlocking pieces, it’s likely that a deep dent or puncture will need to replace an entire panel, instead of just a small piece.
