What are Metal Roofs?
The word “metal” in metal roofs refers to the fact that they consist mainly of either aluminum or steel.
Roof decking in a metal roof consists of two layers of either aluminum or steel, and decking sheathing may consist of two layers of either aluminum or steel.
The roofing materials’ weight and their thick/thin ratios are important to the choice of which type of roof will be appropriate for a building’s structure.
The thickness ratio is the number of inches of roof covering that are covered by one inch (or fraction thereof) of material.
Asphalt-based roof coatings or bitumen are used on the roof decking or sheathing to provide a waterproofing barrier.
The choice of roof type varies based on building type and location. Metal roofs are used for both commercial and residential buildings in all climates.
What are Metal Roofs Made of
Metal roofs are the most common type of roofing on residential buildings. They consist of a single layer of metal, usually aluminum or steel, which is either coated with an asphalt-based waterproofing material or is covered with a layer of bitumen and then coated with a waterproofing coating on top.
The waterproofing coating usually consists of an asphalt-based material that is applied to the roof deck, then coated with a layer of bitumen. In colder climates, two layers of asphalt-based material are used to achieve the same waterproofing effect.
Metal Roofing Types
There are two types of metal roofs: single-ply metal roofs and single-ply metal shingle roofs. Single-ply metallics are not in common use today, although they were more common in the past. Single-ply metal shingle roofs are very popular on residential buildings.
One limitation of both single-ply metal roofs and single-ply metal shingles is that they cannot resist wind uplift pressure.
For that reason, these types of roofs are usually installed on flat or low slope buildings where wind uplift pressures are minimal or non-existent.
Benefits of Metal Roofing
- Metal roofing is one of the most cost-effective roofing technologies that you can find for your home. A metal roofing installation usually costs less than an asphalt or fiberglass shingle roofing installation and will last longer.
- Metal roofs are designed to resist hail storms, which makes them a great choice when protecting your home from storm damage.
- Metal roofs are often associated with an architectural style known as Craftsman Style. This style is a popular choice for most homeowners as it relates to simple and elegant designs.
- Metal roofs can be more energy-efficient than other roofing materials. This means that you will need less energy for heating and cooling your home, which will be an added benefit of installing a metal roof.
- Metal roofs can be customized to fit the style of your home, including different colors and different patterns.
- Metal roofs have fewer seams than asphalt or fiberglass shingle roofs. This makes them easier to install and reduces the overall length of time it takes for your roof to be installed.
- Metal roofing material is generally made from recycled materials, which means that you can help the environment by making your home more environmentally friendly.
- Metal roofs offer high-quality craftsmanship to your roof if you choose to install a metal roof.
Pros And Cons of Metal Roof
Metal roofing has been a popular choice for homeowners, builders, and contractors for a long time.
Pros of Metal Roof: Metal roofs are attractive, affordable, and easy to install. They have a long-life span and are energy efficient.
Cons of Metal Roof: However, they do not have the same insulation and water repellent properties as some other roofs. There is also a higher probability of getting corrosion on the metal due to the nature of metal.
The main issues that affect metal roofs include not enough sound-deadening underlayment or insulation or a roof installation that is not properly fastened, permitting panel shifting due to expansion and contraction. Installing insulating foam under a metal roof can also help reduce roof noise.
Step By Step Metal Roof Installation
- Choose the type of metal roofing that best suits your needs
- Measure the dimensions of your house and garage to determine how much material you will need. Roofing contractors will measure and mark the roof for cutting.
- Remove all debris, dirt, and vegetation from the area where you plan to install a metal roof
- Install any insulation or vapor barrier needed on top of rafters or joists The rubberized underlayment goes down first to help prevent leaks from happening.
- Lay down a layer of felt paper over all surfaces that contact the metal sheets
- Metal is then installed on top of the rafters or trusses with screws, clips, or nails
- Cut out pieces for each side and lay them in place, overlapping at least 2 inches (5 cm) at seams and corners. Once the measurements are taken, they will cut off excess metal.
- Last step is installing a cap sheet which covers any exposed areas that were missed during installation and protects against rust and corrosion
- Finally, install shingle material over the metal roof to complete installation process

Aluminum metal roofing is the most popular and popular type for commercial buildings due to its aesthetic, lightweight, and durability.
An aluminum roof provides easy maintenance, a long lifespan, and comes in a variety of different colors. Aluminum roofing panels are mainly used for architectural roofing and not structural roofing.
It is engineered in many architectural styles depending on the manufacturer of the building material. For example, the metal panels can be attached through fastening techniques such as welding or rivets.
Advantages of Aluminum Roofing
The Advantages of Aluminum Roofing
Aluminum does not corrode. Aluminum is a corrosion-resistant material that is appropriate for locations with heavy rainfall and coastal applications.

- Less Efficient
Steel roofs use more energy in converting heat into power to heat homes or businesses, which is why they are not as efficient as clay tile roofs that do not require electricity to operate.
Are Metal Roofs Loud When It Rains
Metal roofs are actually not quite effective in keeping the noise down. When a metal roof is hit with rain it will make a clashing sound.
Apparently, when insulated with a membrane, metal roofs make less noise than other roofing materials. It is therefore important to use insulation for homes with metal roofs to minimize the noise.
Uncoated standing seam metal roofs can indeed be loud in the rain. Metal roofing profiles therefore require an extra soundproofing material to peacefully quiet in the rain by using sound-absorbing cushion insulators.
