Types of Roofing Sheets Used in House Construction

One of the key elements preventing heat, cold, rain, and snow from entering the house is the roof. A concrete or MS steel structural frame supports a roof.

In contrast to the simpler steel frame, which has columns, trusses, beams, joists, and purlins, the concrete frame simply has columns and beams. A concrete roof or deck slab is attached to the concrete structure. On the other hand, the steel frame is covered in roofing sheets.

Multiple shapes and materials can be used to create a roofing sheet. Roofing sheets are frequently used in residential structures as well as in commercial and industrial structures.

The various roofing sheet types that are available, as well as the benefits and drawbacks of each, will be covered in this blog. We’ll also give you a step-by-step installation guide for roofing sheets and important details to think about when choosing.

Types of Roofing Sheets

Roofing sheets come in a variety of materials to satisfy the needs of diverse sectors. All of these materials are readily available on the market and have a variety of advantages.

Corrugated Sheets

The width of the corrugated sheets is covered in a repeating pattern. The pattern consists of pieces that alternate between plain and ridge. The brand and nature of the material may have an impact on the ridge’s pitch.

Additionally, the ridge’s cross-section could be trapezoidal, semi-circular, semi-oval, etc. Alternating peaks and troughs are another pattern for corrugated sheets.

The two sheets’ longitudinal overlap is made possible by the repeated pattern. Each sheet has an overlap section on one end and an underlap section on the other. As a result, the system of sheets is solidly constructed and prevents water from leaking through the junction.

The majority of roofing systems use the corrugated design because it is dependable, sturdy, leakproof, and long-lasting. Corrugated roofing sheets are frequently used for garages, porches, and sheds.

Metal Sheets

Steel, zinc, aluminium, and tin are basic materials for metal sheets. With the proper upkeep, such as painting, these sheets are strong and endure for decades.

In comparison to other roofing sheets, metal sheets have the benefit of having the highest scrap value. These sheets are an environmentally responsible choice because they are recyclable.

Metal sheets are comparable to other materials in terms of long-term cost when recycling is taken into account. Despite their susceptibility to corrosion, metal sheets offer strong fire resistance. 

Galvanized Iron Sheets

The only distinction between metal sheets and galvanised iron sheets is that the latter rust less. GI sheets are formed of carbon steel and have a continuous hot dipping process-applied zinc coating over them. The sheet is shielded from corrosion by the zinc coating.

The GI sheets are offered in both plain and corrugated designs, and coatings can be used to further protect them. Additionally, the GI sheets are resistant to minor mechanical harm and abrasion.

Clay Roofing Tiles

One of the classic roofing materials utilised for home construction for ages has been clay roofing tiles. The popularity of these eco-friendly and energy-efficient tiles is a result of the demand for more sustainable roofing solutions. Clay tiles are incredibly resilient, resistant to fire, and can tolerate harsh weather. These tiles can also be customised with different colours and textures to give your house a distinctive appearance. Despite being more expensive than other options, installing clay roofing tiles may end up being more affordable in the long run due to power and maintenance savings.

Slate Roofing Tiles

For homeowners seeking a timeless, classic look, slate roofing tiles are a premium option. They can endure up to 100 years with proper maintenance and are resistant to fire, rot, and decay. Slate is more expensive than other roofing materials, but it is a fantastic choice for luxury residences because of its durability and timeless appearance.

Concrete Roofing Tiles

Concrete roofing tiles are a preferred option among homeowners for a number of reasons. They require little upkeep and are enduring. They come in a variety of hues, textures, and shapes and are also excellent insulators. They cost more than asphalt tiles, but they last longer. They are a wonderful option for individuals looking for a long-lasting, low-maintenance roof because they also require little maintenance. 

Asbestos Roofing Sheets

Asbestos roofing sheets, which offer insulation, security, and a durable roof, are made from asbestos fibres and cement. Even though asbestos roofing is incredibly heat and weather resistant, it shouldn’t be utilised in regions that frequently see strong winds, torrential rain, or snow because the material is susceptible to harm. Additionally, due to the health dangers posed by the airborne fibres it produces, several jurisdictions now have legislation that forbids the use of asbestos roofing sheets. When using asbestos roofing sheets, caution should be taken to prevent material disturbance during construction.

Polycarbonate Roofing Sheets

A relatively common form of plastic used as a roofing material is polycarbonate. It is lightweight, affordable, and simple to install. Polycarbonate sheets are frequently used in large-scale industrial and commercial structures. 

The weather resilience and durability of polycarbonate roofing sheets are further advantages. Rain and snow have no effect on these sheets, so maintenance is quite inexpensive.

Additionally, polycarbonate sheets are excellent heat insulators and come in a variety of colours with transparent and translucent patterns. They also block the sun’s damaging UV rays.

Bitumen Sheets

The bitumen sheets come in both corrugated and plain designs. These roofing sheets are comprised of bitumen and fibre, as the name would imply. They have a characteristic black look and are strong.

Bitumen roof sheet’s ability to shed water fast and prevent corrosion is its key benefit. The primary drawback is that it absorbs heat from the sun, raising the inside temperature of the building.

Rubber Sheets

Over the existing roofing sheets, rubber sheets are added to enhance waterproofing and heat resistance. To cover the surface, rubber made of ethylene propylene diene monomer (EPDM) is rolled out and adhered with adhesive or tape. A PVC sheet’s waterproofing performance is 59 times inferior to that of an EPDM with a thickness of 1.2 mm.

Considerations When Selecting Roofing Sheets

When choosing roofing sheets for home construction, several variables need to be taken into consideration. Making an informed choice requires familiarity with all the roofing options, the calibre of the components, and the installation costs.

Roofing Style

Depending on the intended use, roofing sheets will differ. It is crucial to take into account the roofing sheets for residential buildings’ weight, shape, and other functional needs. Choose from a variety of options, such as corrugated metal, engineered wood, and asphalt shingles, to discover the best material for your house.

Material Excellence

When making a decision, the roofing sheets’ quality and longevity should come first. Although more expensive in general, higher-quality materials will last longer and frequently offer a better return on investment in the long run.

Cost of Installation

When choosing roofing sheets, it’s crucial to take installation costs into account. The cost will vary according to the installation’s intricacy, the materials utilised, and the company that is doing the installation. Make sure to check costs to get the choice that offers the best value for your money.

Climate Factors

When choosing roofing sheets, keep in mind the climate of the region where your home is situated. Some materials might perform better in severe or hot, dry environments, whereas other materials might work better in cold, wet environments.

Style When selecting roofing sheets, style is another thing that should be taken into consideration. From classic to modern, many looks can be created using different materials. To best match the design of your house, you can select from a variety of colours, textures, and shapes.

Maintenance

It’s also important to think about the roofing sheets’ maintenance requirements. Make sure to account for the cost and labour of repairs and maintenance because some materials can need more frequent upkeep than others.

You can make an informed selection and select the best roofing sheets for your home by doing research on the various roofing material types, their quality, installation and maintenance costs, and local climate conditions.

Cost

Selecting the proper roofing sheet type for a home’s construction requires careful consideration. Generally speaking, metal roofing is more expensive than asphalt shingles but lasts longer. In contrast, asphalt shingles are less expensive initially but could need more maintenance and replacements over time. Additionally, metal roofing installation frequently takes more labour and specialised tools than asphalt shingle installation, thus labour costs will be greater. Before making a choice, homeowners must ultimately consider the whole cost of both options.

Durability

A roofing sheet’s life expectancy can range from 15 to 50 years, depending on the material and level of maintenance. When properly maintained, metal and stone-coated steel roofing sheets are among the solutions with the longest lifespan, lasting up to 50 years. While asphalt shingles, a more affordable option, typically last 15-20 years, clay tiles are also quite durable and can last up to 50 years. If you want a roofing sheet that will endure longer, think about spending more money on a more robust material.

Design

This is a crucial consideration when choosing roofing sheets for a house. Different roofing materials are available in a variety of sizes and shapes, allowing for a wide range of designs, from simple and conventional to elaborate and futuristic. Trapezoidal, sinusoidal, corrugated, and flat shapes are common. There are additional roofing designs with curves and arches. The colour of the roofing sheets is very vital and has a big effect on how attractive a house looks.

Weight

Lightweight roofing sheets, like corrugated polycarbonate or asphalt shingles, are ideal for homes with lighter roof decks because they are less likely to add excessive weight to the roof structure. Heavier roofing materials, like clay, slate, and metal, should be used for applications requiring higher durability and insulation. Before choosing roofing sheets, it’s vital to have an expert analyse the roof structure’s weight capacity.

Conclusion

Roof covering sheets are an essential component of home construction. By offering cover from severe weather like wind and hail, they defend homes from the elements. In order to keep a home’s temperature at an agreeable level all year long, roofing sheets also add insulation. Providing a barrier to outside sound, they can even assist in reducing noise pollution.
