Roofer FAQs

How to fit a velux window into a slate roof?

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.

Some of my roof tiles are cracked, what should I do?

Roof tiles should be replaced as soon as possible to ensure that your roof stays waterproof. Use crawl boards when replacing them to avoid damaging other tiles, if not ask a qualified roofer to carry out the work, particularly if the tiles are higher up.

how to replace flat roof fascia?

How To Replace Flat Roof Fascia

Whatever makes you decide to install your flat roof fascia by yourself and not a professional company, then you must have a clear idea of what to do and do it appropriately. If you lack proper training and experience, we’d recommend you employ a reliable professional to help with the task for the best results and save you some time and money. This step-by-step guide will give a clear insight on how to go about the replacement of your flat roof fascia.

The tools to be incorporated includes the fascia boards, table saw, plane, crimper, clamps, power nailer, compound saw and chalkline.

• Prepare and get all the necessary tools to complete the task before commencing as this would save you time from stopping and going back and forth looking for the next tool needed,

• Install the sheathing and board.

• Fix white fascias with at least 600mm centres ( a foiled fascia needs just 40mm centre) using a marine grade stainless steel plastic headed nails.

• Make a space of up to 10mm between the joints for possible building expansion, using super glue to secure the joints to just a side of the fascia.

• Place this directly on the fascia board’s top (if you’ll be installing ventilation) to create an air pathway.

• Take note that the type of roof to be installed will determine how you’ll have to install the fascia board. For instance, a hip roof permits you to attach the fascia board onto the roof in a quick fashion, whereas a gabled roof may need you to make markings on the board to achieve the right fit.

• Consider the depth of the fascia board as it also play a huge role in the installation of the fascia board. For instance, there’ll be additional weights on tiled roofs that will push up against the board. Therefore, if you do not get the appropriate amount of depth, it could eventually collapse.

Do you need planning permission for a Velux window?

In general, no – you don’t need planning permission for a Velux window. The Planning Portal says that you don’t need to apply for planning permission to install a roof window if the following conditions are met:

  • A roof window must not protrude more than 150 millimetres above the existing roof plane
  • No roof window or any other alteration can be higher than the highest part of the roof or stand out above the roof ridge
  • Side-facing windows must have obscure glazing to protect privacy of neighbours and, if they open, they must be 1.7 metres above the floor of the room in which they are installed

You don’t need to apply for planning permission for a roof window because they are covered under permitted development rights. However, if you’re a leaseholder or you live in a building where your local authority has made an Article 4 Direction, you will have to apply. Usually, an Article 4 Direction is made when you live in a conservation area where any external home improvements could affect the character and look of the area. Luckily, there are special Velux windows that are designed to be more likely to be accepted by your local planning authority. They’re called conservation windows and, although there’s still no guarantee that they will be accepted, they are designed to look more traditional. Even if you don’t need planning permission for your roof window, you still need to follow any relevant building regulations for your local authority. The most important parts for Velux windows are section J and section L of building regulations, which refer to energy efficiency, thermal insulation and fire protection.

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.

• Identify the existing vent stacks and seal, and put curbs

• Put safety walk pad network from the access point of the roof to the air conditioning units.

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.

What is a Velux window?

A Velux window is a brand of roof window, but the brand is so popular that people often use the name to describe the entire type of window. They are windows that are installed at the same orientation and ‘in plane’ with the surrounding roof, and they’re usually installed at a minimum of a 15-degree pitch. You can buy roof windows that offer completely frameless internal views for a really clean look in your loft conversion, while some come with built-in shutters.

Velux windows aren’t to be confused with rooflights which usually refers to a glazed unit that’s installed on a flat roof. It might also mean a window that’s been installed on a pitched roof out of plane with the level of the tiling.

People also confuse roof windows with skylights, which normally can’t be opened or closed and are usually smaller than Velux windows. Skylights, therefore, only let daylight into the room whereas roof windows also help with ventilation.

If you’re using your loft as a room in your home rather than simply for storage, you must have a roof window installed. Skylights won’t be enough as they don’t allow for ventilation. It doesn’t have to be a Velux window – it can be any type of roof window. Luckily, they tend to come in standard sizes and they must be CE marked if they’re sold as a roof window, so they should be easy to find.
