How To Identify Asbestos Roof Tiles

Found in some particular rocks, asbestos is a naturally occurring mineral that’s commonly used before the 1990’s as a building material specifically for roofing. This material was banned in the UK as it was discovered to possess harmful fibres which is potentially dangerous to human’s respiratory health when disturbed and inhaled. According to several reports this health conditions include non cancerous lung disease, mesothelioma and asbestosis, which are all untreatable. Therefore, be it in a domestic or industrial setting, there’s the need to know how to identify asbestos and if found, start the removal process as quickly as possible.

While the three types of asbestos used in roof tiles can be quite easy to identify by themselves, a total reverse is the case, when mixed into a tile. Generally roofing tiles that includes asbestos will mostly have colours such as grey, white or blue-white colour, but so does several other roof tiles made from other materials that are totally safe. As a result, the only way in which you can identify if a tile contains asbestos is by looking for an identification mark. These marks are mostly inscribed onto about one in twenty tiles, therefore if you have a strong feeling that your roof tiles contains asbestos, you may have to remove several tiles before you can identify the marked one. Otherwise, the only way you can confirm is by sending a sample to a certified asbestos testing lab. These labs are knowledgeable and possess the right equipment, tools as well as testing kits to determine the levels of asbestos in your premises. With this, you have a better chance of getting quality results than any other means. What’s more? They’ll also recommend expert asbestos removal services if the harmful material is found to be present in your house.

Strong winds can cause extensive damage to unprotected rooftops and in fact tiles act as very suitable protection. The extra weight they provide is great at countering high wind loads and if anything is damaged during severe weather, replacing tiles is straight forward for professional roofers.When you compare this to lightweight materials there’s a significant difference. If you wish to have extra protection, experts recommended having sarking fitted.

Do You Need Felt Under Roof Tiles?

Before now, roofing felt were mainly incorporated to serve as a temporary waterproof roof on a building which would later on be changed for the permanent solid tiles or slate roof. This is due to the fact that rebuilding a roof can be time consuming taking a few number of days, the roofing felt would be used to protect the structure as well as the property it contains by acting as a barrier between the house and the harsh elements such as rain, wind, snow, sleet and more, while also providing minimal insulation until the structure is complete.

However those are in the olden days, in recent times, roofing felt ( also referred to as breathable roofing membrane or breathable felt) is now being used to create a safe and waterproof roof which is long lasting and will protect your house, properties as well as other outbuildings for a long period of time while also complying with the Building Regulations. So to answer the question - yes, you’re going to need felt under roof tiles as it has been made mandatory by building regulations.

Now let’s take a look at the different functions served by felt.

✓ You’ll need felt under roof tiles to prevent the roof space from being exposed.

✓ Roofing felt protects homes where a roof has not yet been installed to serve as a temporary protective layer against the elements.

✓ Roofing felt is particularly crucial for modern homes which are constructed to be more energy efficient and work to hold warm air from escaping the house. This is great to reduce your heating bills while also keeping both you and your loved ones cosy all throughout the year.

✓ Overall, building regulations imply that an underlay underneath the slate or tiles is now a compulsory requirement.

The feasibility of this will depend on the roof’s strength, in particular its load bearing capabilities. This is simply because tiles are heavier than the metal sheeting. Normally a tiled roof will need to take a load capacity of 60kg per square metre. You will need a trusted roofing company to advise on this.
