What Is Re Roofing?

Re-roofing refers to a very simple concept that mainly involves the installation of a new roof either on top of the old one or better yet after the complete removal of the old roof in which case the new roof serves as a replacement of the old. As strange as it may sound, although most commonly used roofing materials have a lifespan of 20 to 30 years, fact remains that the roof is still prone to wear out sooner or later in turn prompting repairs running into thousands of dollars if done professionally.

To help you familiarize yourself better with all key aspects of re-roofing, below is a highlight touching on some of the reasons why you should consider re-roofing your home, an overview of the popularly preferred roofing options (including a brief mention of the materials they are made from), summary of the steps involved in re-roofing process as well as a rough estimate of the costs likely to be incurred as a result of this undertaking.

Why you should seriously consider Re-Roofing?

We recently sta down and had a chat to one of our partners about the importance of re roofing a property in Brisbane. Why do you think property owners should re-roof their homes? “I think it is very important these days, especially in Queensland and more importantly due to recent storms we have had, the stronger the roof structure the better chances of surviving the harsh weather conditions”, said Brendon Jones from Masterbuild Roofing Brisbane. “Queensland suffers from unpredictable weather and last year alone we had nearly one billion dollars in damage from the storms”. There are a number of reasons (both functional and aesthetic) for which you should seriously consider re-roofing. Getting in early and preparing in advance can save you time and money in the long run.” he added.

Different Types of Roofs – Choosing Your Materials

Even though installation of a new roof is best left for professionals, choosing the actual materials for your roof will squarely lie on you. To help you make the right choices, below is an overview of the most widely used roofing varieties you should consider. They include:

a. Metal roofing

It is by far the most durable type of roofing and is available in different custom shapes and designs. The best thing about this type of roofing is the fact that it conducts heat easily hence making insulation and control of temperature very easy. This type of roofing is also the best option in cases where the slope of the roof is less than fifteen degrees from horizontal. 
The downsides of having this roof include the fact that it is most susceptible to weathering as well as industrial pollution. This is clearly evident from the fact that its surface is easily scratched and corroded almost at an instant. In addition to the above, it can get very noisy when it is raining though setting up an insulting blanket can help control the noise. One of the most popular metal roof materials in Australia is Colorbond Roofing, you can find out more here.

b. Slate tiles:

They are a common choice for roof replacement. They are made from natural quarried stone and weight much less compared to other common varieties of roofing tiles. During their installation they usually require reinforced framing which to a certain extent make them be somewhat expensive. The best thing about them is the fact that they can easily withstand fire, exceeds moisture as well as insect damage. In fact, it is estimated that their average lifespan exceeds 100 years. This type of roofing is known to provide high standard of weatherproofing, they also look appealing to the eye. 

c. Concrete tiles

It is an excellent choice for imitating wood, clay and slate and is very easy to install. Whats more it comes with lifetime warranties. They however require annual checks for cracked or loose tiles. They are very affordable only that they attract a lot of weight shipping charges.

d. Terracotta tiles

Able to last for 50 – 100 years, they are mainly made from pulverized clay and water. They can be quite heavy measuring up to 1,000 pounds per square. One of the best things about it is the fact that they are energy resistant and also non combustible. They are also available in a variety of color choices.

The Re Roofing Process

Steps involved in Re-Roofing process 

1. Installation of the safety rails

Safety is one of the major concerns during re-roofing. This being the case, prior to commencing any work, it is imperative that you install guard rails all around the perimeter in order to reduce the risk of tillers falling.

2. Removal of old tiles

Next any old roofing tiles and ridges are removed.

3. Thorough Inspection of the roof

This inspection is mainly aimed at making sure that roof timbers and battens are sound.

4. Installation of sarking

Sarking installation is very important because it provides insulation and also reflects up to 95% of radiant heat aimed at the roof.

5. Installation of new battens

This is done in preparation to have the roof ready for laying of new tiles

6. Loading up of the new tiles

At this point, old tile are loaded and sent off the roof while new tiles are loaded up using a conveyer system

7. Laying of the new tiles

New tiles are then laid sequentially on top of the roof right from the gutter line in a manner that secures the entire roof.

8. Installation of Ridge tiles

Ridge tiles are then installed and bedded properly in place using a mortar.

9. Pointing

Pointing simply refers to a flexible material designed specifically for covering the mortar. It comes various colors with the most preferable being that which matches the color of the roofing tile. Pointing serves as a mechanical fastener since it helps keep the ridge properly in place. 

10. Final Inspection

Upon completion, the guard rails are removed and then the site is tidied. After this a roofing specialist is called in to assess the work done.

Costs you should expect

Re Roofing Costs

The cost of re-roofing varies greatly. It is mainly dependant on the size of your roof, type of material amongst other things. The most important factor to take into account is that the material used significantly affects the overall cost of the re-roofing project.

On average, the cost of installing a metal roof stands at around $50 – $100 per square, clay tiles cost nothing less than $100 – $400 per square etc

Simply put, if your home requires a considerably large roof and you are also interested in making advanced additions such as the use of high quality materials, your roofing project would not cost anything less than $5,000.
