Pros And Cons Of Metal Roofs

metal roofing

There are all types of roofs ranging from the style to the material used. Each of the designs has pros and cons. For instance, metal roofs have a longer lifespan, while tile roofs are far more environmentally friendly. If you are looking for a metal roof, there are certain considerations to take into account. This article will describe the different advantages and drawbacks of using metal roofing.

What Are The Benefits To Using Metal Roofs?

1. Increased Life Expectancy

When correctly installed by professionals, such as the Orlando metal roofing company, a metal roof should have a lifespan for as long as the house stands. The metal roof can withstand high winds, seal out water, and shed snow without difficulty. It is also resistant to mildew, fire, rot, and insects. Warranties for this type of roof are dependent on the company used; however, the average warranty is 20 to 40 years.

2. The Roof Weight

As compared to the weight of tile roofs at 750 pounds per square, the metal roof is incredibly lightweight. The average weight of metal runs from 100 to 150 pounds per square. As the material is lightweight, the property owner can save on building the supporting structure and engineering. If you are adding or building a house, you can reduce the number of roof support.

3. Ease And Speed Of Roofing Installation

The majority of metal roof materials are available in multiple-shingle sections. Orlando metal roofing company can easily and quickly install these materials reducing the building timeframe by one or two days. Moreover, there is a considerable saving on labour if you can shorten the duration of roof installation.

4. Increased Fire Resistance

Since metals are non-combustible, they have a Class A fire rating. Class A fire ratings refer to the most fire-resistant materials. It is important to consider that the overall combustible classification of a roof depends on materials below the surface. Metal roofs placed over flammable materials, such as wooden shingles, resulting in a much lower fire rating.

5. Heat Conduction

Due to metal reflecting heat from the sun, you can save energy for other household services, including air conditioning. Metal is low in insulation and can be applied atop foam insulation with high R-values, making it eco-friendly. Furthermore, the systems using dead-air space between the roof deck and metal material increases energy efficiency.

6. Reduced Roof Pitch

The majority of metal roofing materials can be placed on slightly pitch roofs without resulting in leaks. The minimum roof pitch for metal roofs is 12×3.

7. Increased Ability To Shed Rain And Snow

Metal roofing has an increased ability to shed snow and rain, making it almost impervious to these elements. This is due to the manner of panel interlocking, as well as the hard and slippery surfaces.

What Are The Disadvantages Of Using Metal Roofs?

1. Higher Cost

One of the most common drawbacks of using metal roofs is the high initial cost. As the material has long-term durability, you can save in the long-term; however, if you plan to move shortly, you may not get a good return on the investment.

2. Increased Noise

For some people, the sound of rain on a roof is comforting, but for others, it can feel as if you are living inside a drum. Metal roofs can amplify the sound of rain and hail during storms making it noisier than other materials. It should be noted that the noise can be managed using materials with structural barriers; thereby, reducing the “drumming effect.”

3. Increased Denting

Similar to a car that dents when hit, metal roofs can dent if exposed to large hailstones. Aluminium and copper roofing are softer than steel and prone to dents. However, some of these materials are guaranteed not to dent.

4. Leaks

While metal roofing installed by professional metal roofing company n Orlando, FL, can seal against leaks, it is still possible to experience leaking. If the roof has exposed fasteners that are vulnerable to incorrect installation, rainwater can run down and seep into the screw holes. For this reason, specific resilient washes must seal the screw heads.

5. Contraction And Expansion

Since metal expands and contracts according to the temperature, many new products have a system to accommodate the movement. If this system is not applied, fasteners securing the roof can become loose. Moreover, expansion and contraction during hotter days can result in a “wavy effect of the metal roof”.

6. Need For Modifications

If the metal roof is installed using large panels, it can be difficult to replace them when damaged. If you plan to build an addition to the property or remodel the house, it can be difficult to match the exact metal material.

7. Lightening

Most people know metal conducts electricity; however, it also attracts electricity. While metal roofs are not often struck when placed around other high objects, the roof is susceptible to lightning.
