Advances in Roof Technology

Every time we think about technological advances, we fail to recognize the advances in roofing technology.  Nevertheless, a technologically advanced roof makes it more durable and resistant to heat water and natural disasters. If you are looking for a roof that will help you save energy, go for technology. Although we may not offer all the services listed in this article, we have found it fit to inform our dear clients on the latest roofing technological advances so that you can remain informed. The confederation for roofing contractors advises clients to install the most technologically advanced roofs to safe energy and protect their families.

Fire resistance roofing

As technology advances in fireproof coatings, it is availing several options for you to protect your roof from fire. Roofing materials such as wooden shakes will burn easily in case of fire, however if you’re roof is made of tiles, slate or metal, you stand a good chance of avoiding fire damages. Have in mind that roofs made of metal can escalate the intensity of a fire in the house.

To curb such risks from consuming your roof, some companies have invested heavily on technology that can stint the spread of fire. A normal fire occurs due to exothermic reactions whereby there is a production of excess heat which becomes fire. These companies are also considering using volcanic rocks which need a lot of heat to begin a reaction. This stops the generation and spread flames.

Flat roofing

There are newer types of flat roofing that are made of PCV and TPO fabrics which are durable and waterproof. In fact some of them reflect away instead of absorbing it which improves ventilation cutting cost on air conditioning. Most of these techniques are still under development to ensure that they offer value for money.

Cool roofing

This technology is applicable in 2 different ways. Normally, it can be a reflective material which is made to reflect light away to the environment. This prevents absorption of heat reducing the amount of heat that finally reaches your house. Roof that are painted with light colors are generally referred to as cool though some of them are colorless.

Green roofing

Perhaps you are already confused about the difference between a green roof and a cool roof. A green roof stands for a roof that is generally designed to save energy. Garden roofs and solar shingles fit.

Insulation

Overtime, insulating technology has evolved to included fiber glass which is generally woven. Such woven materials provide perfect insulation to ensure for any home. At Eagle Roofing, we strive to ensure that all of the roofs we install are well insulated to ensure that you do not incur unnecessary energy costs. For this reason, we have dedicated our services to be the most tech advanced.

The Many Benefits of Green Flat Roofs

Green flat roofs are the need of this hour as we are tumbling down the lane of environmental crisis at an alarming speed. Green flat roofs can help us play our part in saving what’s left of this environment.

In addition to adding great aesthetic value to your house, green flat roofs can be your small gesture of giving back to the environment.

In case, you are still indecisive about the green roofing option for your house, we have plenty of reasons to convince you. Following are the few of the many benefits of green flat roofs;

Climate Change

  • Green roofs prove to be of great help in fighting off the implications of climate change. It can reduce the velocity and volumes of storm water. You might not be aware of it but Germany, Switzerland and Denmark have promoted the use of green roofs and included them as a major factor in their flood mitigation policies.
  • Green roofs have great insulation characteristics but they do more than saving energy in the house. Green flat roofs have the tendency to keep your house cool in summer and save some serious money on electricity bills.
  • Many installations of green flat roofs can create a micro-climate that can reduce the summer temperature of the entire city.

Repercussions of Urbanization

  • Green flat roofs serve as a barrier between the house and the UV rays emitting from the sun thus increasing the roof life.
  • They help in cleaning environment by absorbing nitrous oxide, which is directly linked with urban vehicles.
  • The plants on green flat roofs purify the air and may reduce the breathing diseases like asthma.
  • Green flat roofs are ideal for urban centers as they maintain the humidity and CO2 levels in the atmosphere.
  • They also enhance the biodiversity by serving as a habitat for many animals.

Noise pollution

It is a common fact that hard surfaces reflect sound thus adding to the noise pollution in the urban areas. However, green flat roofs are known to absorb the noise from the environment, which means it consumes noise pollution from the surrounding and helps in creating a serene environment.

How to get Green Flat Roofs

There are many roofers that offer green roofing but you have to be careful. Since green roofs have a lot to do with plantation and flawless waterproofing, you need the right roofers for the job.

Some roofers involve proper services of gardening experts while laying out the plants on the roof while others tackle the whole project themselves. The former is not better than the latter; it is just different approaches to handle the green roofing job.

Your decision should be made on the expertise and number of years a roofer has spent in the industry and your city.

Why Halifax Roofers prefer synthetic slates over natural slates?

Natural slates have been the roofing choice for many years in the UK and all around the world. However, natural slates come with a ton of baggage which is hard to handle for Halifax Roofers and eventually homeowners. Halifax roofers have figured out a perfect alternative solution for people who prefer the slates as roofs.

Before delving into the solution, let’s briefly delve into the problems with the natural slates;

Issues with natural slates

Natural slates seem to have problems with the production, installation and durability. They are very expensive, for starters.

They are pretty heavy, which makes the transportation and eventually installation a difficult task. Also, natural slates are really delicate to drill, nail or cut. They can crack even by a light impact like foot traffic.

Solution comes in shape of synthetic slates

According to Halifax Roofers, synthetic slates come as a pretty commendable alternative to the natural slates. Synthetic slates are considered as a modern version of the natural ones. They are produced by mixing rubber, plastic and other natural ingredients to intact the look and feel of the natural slates. Also, synthetic slates are much cheaper, they are easier to transport and roofers don’t have any problem installing them.

Here, we would like to delve a bit more into the advantages of synthetic slates;

Recyclable

Synthetic slates are completely recyclable, even the ones that have natural material. Natural slates don’t have this quality and they simply add to the carbon footprint.

Retain Color

The natural slates fade quickly as compared to the synthetic ones because the slates have added ultraviolet inhibitors that fight with the sunlight. However, synthetic slates do slightly change in color after a certain time and exposure to the sun.

Resilient and Durable

Unlike natural slates, synthetic slates are produced in a way to survive the heavy storms and impacts. They are tested in manufacturing factories against different testers to assess their resiliency.

Fire Resistant

The synthetic slates get Class A ratings mostly when it comes to fire resistance. In simple words, they can stand a mighty fire attack and will not spread the fire. However, this quality is hard to compare with the natural slates as they are completely immune to fire. Natural slates get the highest fire resistance ratings among all roofing types.

Costing of Synthetic Slates

The cost of a synthetic slate roof falls somewhat in the middle area. They are expensive than the asphalt and sheet but cheaper than clay tiles and natural slates. Most synthetic slates come with the guarantee of 40 to 50 years. They are known to survive for a century so definitely, the property owners are saving money on the maintenance.

Halifax Roofers Recommend

At the end of the day, the final call is yours. Both natural and synthetic slates are there to stay in the roofing industry for a long time.

Roofers in Halifax Discover the Advantages of Drones for Roof Survey

Commercial buildings are huge and tall. A large company uses its office as a stamp to showcase its strength and magnitude. This philosophy results in giant buildings, which have scores of floors. The signature office buildings serve their purpose but from roofer’s point of view, they create quite a challenge for observational roof checkups.

The ancient method, rather current, is a cherry picker or scaffolding. If you know about these two techniques, you will immediately understand the level of risk, labor and time required to get a roof inspected by professionals. Since it is too risky, the roofers ask for ahefty amount of fees as well.

However, things are going to change pretty soon. Thanks to drones or UAV’s (Unmanned Air Vehicles), inspecting the roofs of really tall buildings isn’t a difficult task anymore. It has completely changed the game in terms of money, time, risk and labor.

Roofers in Halifax tell advantages of drones

Let’s explore few more advantages of drones for roof survey;

Eliminating the risk

Imagine a roofer on a cherry picker trying to get a better look at a roof of a very tall building. The impertinent wind is usually merciless at such heights. The roofer has to fight with the extremely powerful wind and focus on inspecting the roof. There is a major level of threat to his life and at the same time, you are not getting the correct observations too.

Now when we talk about drone, it is controlled by an expert pilot who is sitting in an office on ground. He can maneuver the drone easily and get access to the nook and cranny of the roof without any trouble. Also, the drone has been designed in a way to handle the strong wind pressure. You get high definition images of the roof which enable you to witness the area closely.

Eliminating the disruption

The cherry picker or scaffolding requires a certain amount of preparation. There has to be a number of workers staying alert on ground cordoning off the area and performing other duties. Whereas the drone requires no such protocol, it is a loner who can go up alone and perform an excellent job without any fuss.

Elimination the high cost

We have mentioned drones and it is one of the most advanced technologies of today. However, that doesn’t translate into an elevated cost. In comparison to other methods for roof survey, drones are a much cheaper option.

For further information on using drones commercially in the roofing industry, contact Civil Aviation Authority (CAA) as they are responsible for rules and regulations to use drones in the UK airspace.

Roofers in Halifax are open to welcome such advanced solutions for different roofing tasks as it not only makes their job easy but also satisfies the client.

Why handmade clay tiles are a durable roofing option

The UK is a hub of classical heritage and architecture. There are thousands of historic buildings using handmade clay tiles as roofs. The heritage buildings play a vital role in defining the identity and meaning of this country.

These architectural gems are the reason for much economic growth as well in terms of tourism. Of course, roofs are an integral part of these heritage buildings and in order to maintain them, the preservation of legacy roofing methods and material is important.

Re Roofing Options Today and Why Clay Roofing is still valid

If you are looking for re roofing your house due to any reason, why don’t you give clay roofing a serious shot? There is no harm in talking to your roofer about the possible clay roof for your house.

Handmade clay tiles cannot go out of fashion or market as there are plenty of legacy buildings in the country that require them, either for repair or maintenance. The clay roof has an exceptional quality of looking flawless and enduring the moods of the British weather.

Types of Clay Roofs

Modern machine-made clay tiles

The modern machine-made clay tiles combine two processes to make the final product. The clay tiles are made automatically and just taken off the line manually. The tiles have natural color and they are very durable. The production process of machine made tiles isn’t labor intensive. Machine made tiles prove to be a perfect and cheaper alternative for a traditional look.

Handmade clay tiles

The handmade clay tiles are produced as per set British Standards of strength, resistance and water permeability. Each tile is made by hand which gives it a unique and special appearance and texture. Handmade clay tiles have a very long lifespan. They have been reputed to survive for centuries.

There are many manufacturers that offer different handmade clay tiles options for roofing in order to recreate the traditional look and flawlessness of heritage structures.

Clay Roofing requires Expert Roofer

It is generally believed that machine made clay tiles are easier to use in a roof than the handmade ones. Well, it is not true as both types of clay tiles take an equal amount of time and effort. However, it is true that clay roofing is a trickier task and only expert roofers can handle it.

For re roofing with clay tiles, you must pick the right roofer and check his credentials.
