Corrugated Roofing: What Is It and Why You Should Get It

Corrugated Roofing: What Is It and Why You Should Get It

What is corrugated roofing?

A type of roofing, corrugated roofing is made of corrugated roof sheets that come in plastic or metal. These types are sheets differ from other sheets in the way their surface is designed. Instead of being flat, the sheet has an undulating and ridged surface. Additionally, the sheets are not haphazardly placed over one another. In fact, each sheet has a slim lap that overlaps with a flat lap and is overlapped while taking the wind direction into account.

Traditionally made of iron, copper, aluminum, and steel, corrugated roofing is mostly used in commercial, industrial, and farming settings. However, in recent years a trend has emerged to install this type of roofing for homes as well. More and more residential homeowners wanting metal corrugated roofing has increased the demand for the product. And it comes as no surprise, considering all the benefits it confers on homeowners.

1. Corrugated aluminum roofing

Corrugated aluminum roofing offers both value and quality, is durable and rust resistant. It doesn’t require additional coating and can be painted a wide range of colors.

2. Corrugated steel roofing

Corrugated steel roofing has a natural gray finish to it that may look drab on a residential home. While it may work on certain designs, it is an expensive alternative that won’t necessarily blend well with others. Additionally, it is harder to change the initial color of the material.

3. Corrugated copper roofing

Corrugated copper roofing is most of the time avoided by residential homeowners because of the hefty price tag that accompanies it. While it is easy to install and is naturally resistant to rust, other options come with the same benefits but at a cheaper cost.

Why install corrugated roofing for your house?

The properties and signature shape of a corrugated metal roof can give your home added protection. Durable, resistant to extreme weather, yet lightweight, corrugated metal roofs are the perfect choice for many construction projects.

1. Corrugated roofing has a long lifespan.

Metal characteristics allow for metal roofs to last for a long time. While average quality, flat metal roofs usually last for about 30 years, corrugated metal sheets can last for over 50 years on average. This is thanks to its shape, which makes it less prone to corrosion.

Recent advances in technology, such as galvanizing, has upgraded this metal roofing from simple sheets to a corrosion-resistant and rust-resistant material that is highly sought-after.  

2. Corrugated roofing is durable.

The rippled surface of corrugated sheets creates a larger surface that has increased durability. This type of roofing can, hence, withstand impacts from large objects that fall may fall on it. These include impacts from pebbles and branches.

It may be hard to believe, but even lightweight materials that are usually considered to be flimsy, such as aluminum, can become sturdy. All thanks to the shape and positioning of the sheets!

3. Corrugated roofing offers excellent weather protection.

Corrugated metal panels are able to withstand extreme weather conditions. Whether it is hail and snow, heat waves, hurricanes, this type of metal roof is highly resistant to harsh weather.

Metal rooftops also now have fire-resistant properties that make them non-combustible.

Installing a corrugated rooftop

Installing this type of roof can be a fun Do-It-Yourself project that you can complete with a friend or family member. Below is a list of tools you will need for the installation:

  1. Gloves
  2. Safety goggles
  3. Measuring tape
  4. Hammer
  5. Cement (especially for meant for the roof)
  6. Nails
  7. Screwdriver
  8. Washers and wood screws
  9. Roofing felt
  10. Staples
  11. Staple gun
  12. Metal panels
  13. Polyurethane sealant
  14. Ridge peak

You are now ready to start installing the corrugated sheets.

1. Get all measurements right

Start by measuring the width, length, peak, and slope of the roof.  

2. Install the purlins

Install the purlins on the roof and ensure that they are equally spaced.

3. Purchase and cut the panels

You will need more panels than the dimensions you got when measuring the roof. This is simply because the sheets will overlap. Buy the corrugated roof panels and cut them to the length of the roof by using circular saws, tin snips, and angle grinders.  

4. Drill holes in the sheets

Before even placing the sheets over the roof, drill holes in them vertically and have the hole be around 6 to 8 inches apart.

5. Installation of the sheets

Place the panels on the purlins in an up and down pattern.

6. Seal the panels

Seal the panels with water-resistant sealant.

7. Screw the corrugated sheets in place

Fasten the panels to the purlins using a polycarbonate washer for the screw. Repeat until you’ve affixed all the screws. You can now add the side ridge flashing, headwall connector flashing, and ridge cap if necessary.


Residential and Commercial Roofing

It can be quite difficult to choose the perfect type of roofing for your retrofitting, new house or commercial buildings.

We have so many choices out there nowadays that you might be wondering as to which is the right one for home or commercial buildings! The roofing options that are available will certainly help you find an effective way to cover your home or commercial buildings.

For residential roofs, Ceramic Tiles, Asphalt, Wood, Slates and so on, have proven to be appropriate with Asphalt being the most common one. As for commercial buildings, the most appropriate roofing can be Built-Up Roofing (BUR) Membrane, Modified Bitumen Roofing, Thermoset (EPDM) Roof Membrane, Thermoplastic (PVC & TPO) Roof Membrane, among others.

Below are some of the most common roofing types along with their advantages:

Asphalt Shingles

  • Fiberglass Shingles–They are made of a fiberglass-base mat, layered with a waterproof coating, and topped with ceramic granules reflecting UV rays.
  • Organic Shingles–Organic shingles are initially made of wood chips, rags, recycled cardboard, or paper. They also have a layer of asphalt to make them waterproof.
  • Three-Tab Shingles–These are shingles with cutouts running along the bottom edge and they are less expensive.
  • Architectural Shingles–They aren’t made with cutouts and aren’t recommended for low slope roofs.

Tiles

  • Tile Shingles–Perfect if you are looking for stylish roofing. Often used on colonial Spanish or Mediterranean style properties.
  • Ceramic Tiles–Generally durable, fireproof, fade resistant and can last up to 50+ years.
  • Slate Tiles–Most appropriate if you wish to have sophisticated roofing material for an upscale home (Fire resistant with an expected life of 100 years)

Wood Shakes/Shingles or Cedar Shingles

Wood Shakes

Wood Shakes

• The price is more affordable than other shingles and expensive tiles.
• Durable and more green-friendly, if constructed from recycled or harvested wood.
• The materials produce a minimal impact on the quality of water runoff with a lifetime of 30+ years.

Cedar Shingles

  • Cedar shingles are well grounded and ideal for homeowners wishing for long-lasting roofs.
  • Recommended for sunny and hot regions as they are UV damage resistant.
  • These shingles can easily tolerate extreme weather conditions.

Metal Roofing

  •  This is becoming more achievable nowadays, as they are more environmentally friendly and less costly.
  •  One important factor to be considered about Metal Roofing is that it can at times be quite noisy whenever it is raining. If you don’t take good care of the metal roof, inconveniences such as loose nails, rusted patches, leaks, and moisture may arise.

However, on an ending note, out of the several roofing methods mentioned above, Metal Roofing is said to be appropriate for both residential and commercial building roofs.
