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.

How To Clean A Roof?

If you’re planning to clean your roof, but don’t know where to start, you’ve come to the right place! There are different types of roofs available in the market today and the method used in cleaning one can be largely different from the other. As a result, we’re only going to look at one of the common types of roofs you’ll find in the UK - the Asphalt shingle roof tiles. This roof type is very common and for a good reason. Not only are they visually appealing but they’re also hugely versatile by design which enables them to be adaptable to varying shapes, angles as well as forms depending on your preference or needs. With all the benefits that can be derived from asphalt shingle, they however, need to be properly maintained to help retain their good looks.

To clean your asphalt shingles, you’ll most likely require some type of chemicals especially when dealing with algae stains and some other visual problems. Therefore, make sure you purchase a product marked safe to be used on this type of roof and not those only proven to remove moss and algae stains. Mix the chemical cleaner with a gallon of water and a quart of bleach or as instructed by the manufacturer. Pour the mixture inside a pump-style garden sprayer and mix thoroughly. When done, climb up on the roof and spray as good as you can. Upon completion of spraying the roof with the mixture, then allow to work its magic for some time - about 15 minutes or thereabout should be good.

After that, you can make use of a garden hose to spray down the roof and wash down the mixture entirely. If some stains remain, use a brush to gently wipe the tiles individually.

Tar and gravel flat roofs are popular because the gravel weighs down the surface of the roof so it doesn’t blow away and it also protects it from sun damage. The tar makes the roof watertight, so you won’t get any leaks. However, sometimes problems occur and you’ll get cracks and leaks. So how do you repair a tar and gravel flat roof?

If you notice leaking coming through your flat roof, try to find the source of the leak. Since water can travel easily, it might not be where you think it is. The first place to check is the flashing, then any parts of the roof with gravel missing. Once you’ve found the crack, sweep away any remaining gravel and clean the area.

Apply a primer to the area and allow it to dry. Then, apply a tar and gravel roof patch that you can get from most DIY shops. Patch 2-3 inches around the damaged area, creating layers, and ensuring that there aren’t any air bubbles or gaps. Then you should cover the entire patch with gravel.

Before you try to repair a tar and gravel flat roof yourself, consider how much of the roof needs repairing. Professionals often say that if cracks and faults make up 25% or more of the roof, then you should look to replace it. It might be tempting to try and replace your tar and gravel roof yourself, but it’s best left to the specialists. They will ensure that your new roof is watertight and strong enough to withstand sun damage and storms.

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.

It depends on the material you use, but if your flat roof is installed correctly it should last for at least 10 years, and at least 20 if a material other than felt is used. Always question a roofing company when they quote to find out what materials they use and what guarantee's they offer.
