Roofer FAQs

how to identify asbestos roof tiles?

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 fibreglass roof?

How To Clean A Fibreglass Roof?

If you have a dirty fibreglass roof or perhaps you’re just planning to have one installed on a newly constructed house, then you’d probably want to know the best way to have your fibreglass roof cleaned.

Generally, fibreglass roofs are of great quality and happens to be a lot more resistant to moisture, heat, water and even fire when compared to the other alternative flat roofing materials. As a result, they require just a little maintenance but this doesn’t mean they should be totally ignored. Truth be told, cleaning of a fibreglass roof is as easy as it get, however, when it comes to working at height, skill and confidence is paramount to guarantee your safety. If you lack any of these two qualities, then it’s highly recommended that you sought the services of a reliable roof cleaning contractor who can do the work safely and perfectly. If you’re able to clean and maintain your fibreglass roof as you should, you wouldn’t have to think about replacement for about 20 to 30 years.

Cleaning is simple and doesn’t take much time. Now let’s take a look at the process.

✓ Preparation. Hose down the vegetation around the area with water to protect them. Once done, mix a gallon of warm water with one quarter cup trisodium phosphate and 1 quart of bleach. Put this mixture into a garden sprayer and sweep any dirt or debris off the roof with a broom.

✓ Application. Spray the mixture over the fibreglass roof, ensuring that it gets to all the necessary corners where dirt may be hidden. Allow this applied solution to sit for up to 15 minutes to loosen the stubborn stains and dirts on the roof.

✓ Finishing. Spray cold water to wash down all the solutions. If there’s still some dirts, you can repeat the process till the fibreglass roof is entirely clean.

How to repair a felt flat roof?

It can be easy to repair a felt flat roof depending on the problem. If you’ve got an old-style pour-and-roll felt flat roof, you might be starting to run into problems, but even if you have a newer torch-on felt roof, issues can occur. You might find cracks, lifting, leaking flashings or dips and hollows in the felt. Luckily, there are some easy fixes – but the best thing to do to prolong the life of your felt flat roof is to get a professional to look at it.

If your felt flat roof only needs a small repair, you might be able to get away with using a paint-on fix from a tin that you just brush on. However, if you want a more permanent fix, you’ll need a few more tools and supplies.

You can use a patch of torched-on roofing felt over the crack or leak, but if your flat roof is very damaged or wet it might not take it. You can also buy liquid systems for felt roofs, but again, there is a possibility that your roof might not take it. Also most of the high-quality liquid systems are only available for trade customers, so you might be better off asking a roofing pro to do it for you.

What is overlaying?

If your existing roof is still in good condition but the membrane is getting old, it’s often not worth exposing the structure to the weather whilst the contractor strips off the old membranes. The contractor will leave them in place to act as a base layer for a new roofing system. As long as there are no other problems with your roof, then overlaying is a good way to replace your flat roof.If you have any more questions about flat roofing that aren’t listed here, fill out our form to ask a contractor.

How to clean Velux windows?

Velux windows, or roof windows, are very easy to clean. Regular cleaning helps to keep them looking bright and shiny for years to come. So how should you clean Velux windows?

If you want to clean the air filter, you can remove it and wash it with your normal household cleaners. Velux windows have a cleaning position, so rotate and secure it into this position then remove the filter. You should be able to buy new filters from the manufacturer of your roof window.

To clean the outer pane, there’s no need to lean out of the window and risk falling out. Simply rotate the sash (the opening part) 180 degrees and secure it into position. Then you can clean the pane with a soft, lint-free cloth, sponge or squeegee and clean water. If you live in a hard water area, add some detergent to the water and wipe the window dry when you’re finished. You can also use normal non-abrasive household cleaners.

It’s recommended that you clean the flashing around your roof window at least once a year. You can use a brush to do this. This will allow rainwater to flow freely and stop any leaves from collecting.

If you’re in any doubt about using certain cleaners on your Velux windows, get in touch with the manufacturer who should be able to help. You can also do a patch test on an inconspicuous area if you’re unsure.

how much to replace a flat roof?

How Much To Replace A Flat Roof

There’s no straight answer to this question. However, the average cost lies within the range of £1000 to £5000. This range may look too wide but the price is greatly influenced by a number of factors which is capable of making the price increase or decrease. Some of the factors affecting the cost of flat roof coverings and replacement include: the type of flat roofing system and materials you want, the area size of the flat roof in M2, the project’s location, the roofing company to be used, the ease at which to reach the roof, cost of removing the old flat roof as well as cost of removing the other waste.

Although there are many factors to be put into consideration but the most crucial factor is the size of the house or the area size of the flat roof in M2. for instance, a one bedroom apartment’s flat roof will have a price between £1500 to £3000. This is, however, with the assumption that the flat roof is going to be used as the main roof of the house. But if you’re only using it for a section of the house like your garage, the price could range between £700 to £1000

There four commonly used types of flat roof materials which includes fibreglass, felt, rubber and lead. If you need a felt roof, for example, the price is between £40 to £70 per m2. And in the same tone, a metal roof will generally cost more than a a flat roof made from rubber.

Another important factor we’ll discuss is the labour or the roofing company to be used. Different roofing companies will charge different prices. As a result, you should carefully compare the prices of the companies in order to get a great deal.

What guarantee or warranty can I get?

Most material warranties come from the waterproofing layer manufacturers, and can last between 5 and 20 years.

It’s important that you always read through all the information given to you about your warranty so you know exactly what is included.
