If you’ve never had Velux windows before, you might be wondering how to open them. If you’ve got very high ceilings and your roof windows are set high up in the pitch of the roof, you might not even be able to reach them. So how do you open them in this case?

When Velux windows are installed so high that they’re out of reach, the installers will often recommend that they install an electric switch for you to open and close your windows. They often come with a rain sensor, so you don’t need to rush up to the top of the house if there’s a sudden downpour – they will close automatically. You can also choose to have a remote so you can open and close your roof windows wherever you are in the room.

If you don’t have an electric switch, but you still can’t reach to open and close your Velux windows, you should be supplied with a telescopic pole when they’re installed. If you weren’t or you’ve moved into a home with roof windows and there isn’t one, you can buy them online. They have a hook on the end and can be extended to the correct length so you can hook it over the handle of the window and pull or push to open it.

If you’ve got a top-hung Velux window that can also be opened in a centre-pivot position, it’s easy to switch between the two. Simply ensure the window is completely closed before you start, then open the handle up – but don’t push it out. Then pull the vent bar down until the sash is rotated 180 degrees. Then secure the position by sliding the barrel bolts into the holes at either side of the bottom of the frame. Easy!

It’s relatively simple to remove a Velux window, whether it’s Velux-branded or is another brand of roof window. Here is a breakdown of the steps you’ll need to take to remove a roof window:

1. Remove the sash (opening part) from the roof window frame. Usually there are screws in the hinges to loosen or a button to press and lift out.
2. Next, remove the tiles or slates from around the window frame along with the flashing.
3. Unscrew all the brackets around the window frame and lift out the frame.

It’s that simple! You can do all of this from inside your home – there's no need to climb on the roof. Removing the glass pane from a Velux window, for example if it has blown, is a more difficult job and should be left to a professional. It involves removing the sash from the roof window frame and then removing the surrounding parts of the sash to lift out the sealed unit. They will then place the new glazed unit into the sash frame before securing all the parts back onto the sash and fitting it back into the roof window frame.

Will My Roof Leak With Missing Ridge Tiles?

Your roof is the first line of defence against the elements. Therefore, if you want your home protected at all times, there’s a need to ensure a professional inspection of your home at least once a year. However, there are certain issues that you do not have to wait for a professional to be able to spot by yourself. And an example of this includes a missing ridge tile. This issue is noticeable from the ground level while some tiles may even fall off and notifying you in the process. If you’re currently facing this kind of challenge, you’d probably want to know if the missing ridge tiles can cause your roof to leak. In this article, we aim to answer this question and more. Let’s take a look!

Firstly, there are a number of causes of missing tiles or slates and the most obvious is the weather. When the wind or rain gets very high, it can pull your tiles out of place and even more more, if they weren’t properly installed in the first place. Secondly, there’s also a chance that the nails may wear away. These are the nails that holds your ridge tiles in place, they can rust and wear away, hence leading to missing ridge tiles.

Therefore, the short answer to the question is yes, missing ridge tiles can cause your roof to leak. Even if it doesn’t leave a visible gap in your roof’s covering, it’ll create a break in the roof which weather can easily penetrate. And allowing this to happen makes the other tiles more susceptible to damage which won’t be good for the entire house as well as your pocket. Hence, once you notice a missing ridge tile ensure to have it replaced as soon as possible.

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.

Ponding is where you see pools of water appearing on your flat roof. Unless your roof is leaking or showing other signs of damage, you don’t need to replace it. When you do have your flat roof replaced, tell the contractor so they can find out the cause of the ponding.

How Much Does It Cost To Have Roof Cleaned?

If your roof is dirty, it’s highly recommended that you have it cleaned by a reliable and professional roof cleaning contractor who specializes in cleaning of all types of roofs rather than making it a DIY project or hiring an odd job man who is a jack of all trades. This is due to fact that major mistakes like incorporating inappropriate cleaning agents, pressure as well as wrong cleaning techniques can have a serious negative impact on your home while also putting in mind the several dangers that comes with working at height. However, when hiring a professional roof cleaning person or company, do make sure that the cleaner is fully insured, possesses the relevant training working at height and has the ability to operate access machinery. In other words, when it comes to roof cleaning where safety is the first priority, it shouldn’t always be about the price of the job but the quality of the service you’re going to receive.

Fitting a Velux window into a slate roof is very similar to the way you’d install it in other roof types. All roof windows, whether a Velux-branded one or not, will come with detailed instructions for you to follow if you want to have a go at fitting it yourself. But here are some brief instructions to give you an idea of what’s involved in installing a Velux window into a slate roof:

1. After you’ve removed the Velux window from its packaging, remove the sash (the part that opens) from the frame, according to the manufacturer’s instructions.
2. Next, you need to prepare the opening for the window. You can often cut through the felt, remove one of the battens from under a slate, then slide all the slate tiles into the roof space. You should then make the cut 40-60mm wider than the window, cutting away roof timbers then replacing them with more around the opening to strengthen it.
3. The roof window’s bottom brackets need to be installed on one of the existing battens for the slate roof. One of the slate courses should line up 105mm below the top edge of the batten you use.
4. Then, measure from the top edge of the batten upwards to the height of the window plus 45mm. This is where the top installation batten should be installed, with an overhang of 100mm on each side.
5. Remove the course of slates below the window, trim any excess felt and fold it over the surrounding timber. This helps with waterproofing.
6. Add the insulation collar according to the Velux window manufacturer’s instructions.
7. Place the frame in the opening, adding the brackets according to the instructions. You’ll find that lots of roof windows have pre-drilled holes to make it easy for you.
8. Replace the sash and line up the hinges. Take a look at the opening at the bottom between the sash and the frame – it should be even along the entire width. Remove the sash again to fix the upper brackets according to instructions.
9. Add the underfelt collar for your roof window as instructed by the manufacturer, then replace any slates at the bottom. You might need to cut them to size.
10. Next, add the flashing according to the instructions, along with any parts that are not yet attached, including the hood section and top flashing piece.
11. Replace all the slates around the window, allowing 60-100mm of space between the course of slates above the window and the top of the window to allow for rainwater drainage. Then replace the sash into the frame again.
12. Add the vapour barrier on the inside of the window using the screws provided, then tape it to the existing vapour barrier to prevent moisture from reaching your roof structure.

And that’s it! If you think that sounds a bit complicated, ask a roofer or window installer to fit your roof window into a slate roof for you. You’ll get a better finish and you can be sure that you won’t get any leaks from a botched installation.
