What Is Roofing?

As you could have already guessed, roofing is the material used in a building’s roof  Generally, people use the word “roofing” to refer only to the outer roof covering, though sometimes, the word is used to refer to the entire roof system as well.

The importance of understanding roofing when looking for roofers in Dublin lies in the fact that you want to invest in the right type of roofing for your needs. With that, we’ll now dive into the subject a little bit deeper.

Key Parts Of A Roof System

A roof system actually is more complex than you might be thinking. It incorporates the following key components – roof covering, sheathing, roof structure, flashing, and a drainage system.

The roof covering along with its drainage system is what you see from the outside, while the rest makes up their structural support. Although the roof covering is the most visible component of your roof system, the quality and strength of its supports matter just as much for your property, or perhaps even more.

A strong and heavy roof covering without correspondingly sturdy support will not live long and won’t be able to perform its function. Likewise, if you have excellent support under the roof cover but not enough protection from outdoor elements, moisture will seep into your home, damaging everything in its path.

So even if you are looking to only replace the outer cover of your roof, you should understand what’s going on under it. With that, here’s a brief description of the purposes of the five key components we listed earlier.

Roof covering: Roofers Dublin

The roof covering is, needless to say, the outermost component of a roof system. It may consist of shingles, tile, metal, and underlayment to protect inner layers from weather and sunlight.

Aside from that, the covering performs an aesthetic function, so you may want to match the style of your roof to the rest of your property.

Sheathing: Roofers Dublin

Sheathing (also known as roof decking) is fastened right under the roof covering to your roof rafters. Basically, sheathing is boards or sheets of material fastened to other components of the roof structure.

Usually, roof sheathing is made of either plywood or oriented strand board (OSB). Plywood is the more durable material of the two, while OSB costs less. If the roof cover material isn’t too heavy, contractors prefer to use OSB.

Roof structure: Roofers Dublin

The roof structure consists of trusses, joists, and rafters. These components serve as supports for the two outer roof layers, and they also give shape to your roof.


Flashing consists of sheet metal or other materials mounted to joists and valleys to keep water out.

Typically, roof flashing is made of galvanized steel, and it covers only critical areas of the roof to direct away water. Flashing is usually installed in areas where the roof meets a vertical surface, such as a wall or chimney.

Thanks to the flashing, water slides down the shingles instead of seeping through your home’s structure.

Roof gutter: Roofers Dublin

The purpose of the roof gutter is to collect water flowing down the roof. Roof gutters are used to control the water flow and prevent water from rushing down onto the heads of bystanders or from damaging the building walls.

Roof gutters are especially important with flat roofs since large amounts of accumulated water may excessively load the roof.

Popular Materials Used In Roofing

Now, let’s talk a bit about roofing materials. Here, we mean specifically the outer roof cover, not the entire roof system.

Roofing is made with various materials, and which type to choose depends on your budget and requirements. Below is a brief description of the most popular roofing materials on the market to help you choose.

Wooden roof: Roofers Dublin

Wooden roofs are arguably the best-looking roofs you can ever have on top of your home, but they have some serious limitations. Wood is sensitive to moisture, and it also is a dangerous choice in areas with frequent wildfires.

Unless your home is in a moderate area with infrequent rains and cooler temperatures, wood is perhaps the worst choice. But in the right conditions and with adequate maintenance, wooden roofs can serve you for decades.

Metal roof: Roofers Dublin

Metal roofing offers excellent durability – it’s excellent at shedding snow and rain, does not burn, and resists winds. You could expect a metal roof to serve you for decades. Metal roofing is rather light as well, so it can be installed over an existing roof or over weaker roof structures.

There are some downsides to metal roofing as well. It’s on the pricier side, and not every roofing company will have the skills or the equipment to install a metal roof.

Aside from that, the metal may dent from impact (during hail, for example), and it may rust from exposure to water, though some metals (such as galvanized steel) are resistant to corrosion.

Tile roof: Roofers Dublin

Tile roofing is commonly made of clay or concrete. Both materials offer more or less the same performance and durability, but concrete tile is noticeably cheaper.

Tile roofs are great in warm, dry areas where the air has high salt content. Due to their resistance to heat and salt, tile roofing is common in coastal or desert regions.

Tile is heavy as well, which allows for increased resistance to hurricanes, tornadoes, and strong winds. However, tile is rather fragile and can crack if you walk on it. With careful use though, tile roofing could last over a century – more than anyone would need in their lifetime.

Keep in mind that concrete tiles are more absorbent than clay tiles, so they are more prone to the development of mold and mildew. They require more maintenance as well. These are part of the reason why concrete tile roofing is generally cheaper than its clay counterpart.

Asphalt composite roof: Roofers Dublin

Asphalt composite roofing consists of a fiberglass base covered with asphalt and mineral granules. For most household needs, this style of roofing is the optimal choice.

Asphalt composite roofs are very popular around the world – especially in America – thanks to their durability and resistance to weather. Aside from that, the shingles that make up this style of roofing are very easy to replace.

Asphalt composite roofing is rather inexpensive, and although it doesn’t last as long as metal or tile roofing, you could get about 30 years out of it.

Slate roof: Roofers Dublin

Slate roofing is very, very expensive, but it can easily last a hundred years and is resistant to fire, water, and the formation of mold.

However, like tile, slate is heavy and resistant to winds but cracks easily when stepped on. Hail may break slate too, so in some regions, it may not be the best choice.

Traditional slate roofing is made of real stone, and its installation requires skill. Finding contractors who have experience with slate roofing is difficult, so even if you have the budget, it might be challenging to have slate roofing set up in your area.

Synthetic slate roof: Roofers Dublin

Made of rubber, synthetic slate roofing is nearly indistinguishable from the real thing, but it’s much less expensive and much less durable. With that said, getting up to 50 years is quite easy with synthetic slate.

Synthetic slate roofing has a few upsides as well. It’s much lighter than natural slate and the weak houses use this roofing because they can’t support slat roofing. Aside from that, synthetic slate is more resistant to impact and doesn’t crack that easily.

Final Words: Roofers Dublin

Hopefully, you are now a little more informed about the styles of roofing that you can find out there. As your next step before getting in touch with roofers in Dublin, we recommend that you research roof installation or repair pricing – depending on what you need, of course.

With that said, remember that until a contractor inspects your property, you won’t get accurate estimates. Likewise, until you get in touch with a pro, you won’t be able to determine which roofing material is best for you.

So if you are thinking of replacing your roof, don’t hesitate for too long! If you have the budget, start working as soon as you can since a bad roof above your head is a threat to your security and comfort.
