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.

One of the most popular choices for roofing materials are roof slates. There is a number of advantages that a roof slate has, hey can be aesthetically pleasing, they can also increase the potential selling value of the house and many more. Slate is a sturdy and resilient material that delivers waterproofing physical characteristics to a pitched roof. Unlike other roof materials which absorb water slates do not. Therefore, slate is the most resistant towards freezing and water damage.

Find out the pitch of your roof

Before beginning with the fitting procedure, you need to figure out the pitch of your roof. The roof pitch commands how much overlap is essential with each slate. This has been made a lot easier than the early days with the advancement of technology.

Find out the required overlap

Once you’ve found out the exact pitch of your roof accurately, take a look at the slate producer’s description. Each manufacturer will propose the obligatory overlap in order to form a firm and safe slate roof.

Roll out the roof membrane

Firstly, guarantee your joists or trusses are clean of any sheards or old nails that could harm the membrane. You will now have to roll the chosen roofing membrane along the roof trusses. It is always wise to start from one of the bottom corners and keep rolling it along to the other corner.

Secure the roof membrane

Once the membrane has been moved out, use thump nails to protect one edge. You will now have to pull the membrane taut and carefully fix it into position. Do this before adding any nails across the membrane at points of intersection with the trusses for extra stability.

Batten placement

This is done to find the proper assignment of the battens. For this, you will need two full-sized slates along with an under eaves slate. Carefully position the battens on the top of the roof on the top of the overlay. Make sure not to fix them down since it will be easier to move them around and make any adjustments.

How Often Do Flat Roofs Need Replacing?

When a flat roof needs to be replaced is determined by a number of factors which includes the roof’s exposure to the weather, the condition and age of the roofing materials as well as the construction of the roof. However, with proper maintenance and regular inspection, they should be used for nothing less than 50 years. There are some commonly used types of flat roofs which includes Felt flat roof as well as a GRP flat roof.

Felt Flat Roof

The lifespan of a felt flat roof also varies depending on the quality and grade of the felt roof incorporated. This can make the roof last within the range of 2 to 20 years. More often than not, felt flat roofs are usually installed in such a way to keep the costs down which implies the grades of felts that are mostly used are the economical ones implying a very short lifespan.

In the event whereby a premium grade of felt is incorporated in constructing a roof by professional contractors, will be guaranteed by the manufacturer to last between 10 to 20 years.

One of the major causes of a short lifespan in felts is leaks which should be regularly inspected and repaired once identified. If not, the roof will gradually deteriorate and become a lot weaker due to the action of the sun. However, when a felt roof starts to leak, it’s usually a sign that’s approaching the end of its lifespan and a replacement should be taken into account.

GRP Flat Roof

The GRP flat roof or fibreglass flat roof usually comes with a manufacturer’s guarantee of 20 years and is expected to have a lifespan of a minimum of an additional 10 years.

Unlike felt roofs, they’re more resistant to leaks. However, they should also be regularly inspected for leaks which are caused mostly as a result of installation error rather than the GRP roofing approaching the end of its useful life. If the GRP roof repair does not totally resolve the leak, you should start considering a replacement.

How To Clean Roof Lights

If you have existing roof lights or perhaps you’re about to have them installed, it’s important to know just how to have them cleaned, even if you wouldn’t be doing it yourself. Generally, glass roof lights fitted in flat roof applications are more likely to be a major victim of staining and discolouration by several elements like rainwater, bird droppings, vehicle exhaust pollutants as well as tree sap. Therefore, just like any other parts of your home, periodic inspection of the units as well as regular cleaning is highly advised to help maintain their top performance for a lengthy period of time.

Firstly, when installing the roof lights, it’ll be helpful if its fitted at the right pitch so as to help keep the exterior clean as it enables the elements such as rainwater to run off the surface naturally. Cleaning roof lights involves working at height which can be very dangerous. Therefore, if you lack the skill and confidence to pull this off, it’s advisable to hire the services of a professional who can guarantee the best results for help. In this article, we aim to give you a good insight into how the roof light cleaning process works. Let’s have a look!

Rooflight Interior Cleaning

✓ Spread plastic under the roof light to catch dirt and spills

✓ Dust to wipe clear all loose dirt and cobwebs.

✓ Use a squeegee with a warm soapy water or any other glass cleaning product to clean the glass ( steer clear of any harsh chemicals or abrasive cleaners)

✓ Dry the roof light with a soft and lint-free cloth.

Rooflight Exterior Cleaning

✓ Access the roof safely with a specialist ladder

✓ Put mild detergent into a bucket and carry up to the roof before filling with warm water from a hosepipe

✓ Use the soapy water and a non-abrasive cloth or squeegee to clean the roof light, its surroundings as well as fixings.

Commercial roofing simply refers to any roofing work, including installation and repair, that is done to commercial buildings. This might include office roofs, shop roofs or commercial unit roofs. Every building needs a roof to keep out the rain!

Since looks aren’t usually the first priority with commercial buildings, lots of commercial properties have flat roofs. These are often made from felt, EDPM rubber or fibreglass. Felt is the cheapest commercial roofing material, while fibreglass tends to be the most expensive. In felt roofs, roofers use an adhesive to stick roofing felt onto a frame. EDPM rubber roofs have a rubber membrane that is laid down and glued onto the roof and coated with a contact adhesive, while fibreglass uses a cut glass fibre mat that is pressed on before a resin and topcoat are applied.

Not all roofing companies will offer commercial roofing services, because generally the buildings tend to be bigger. Small companies won’t have enough tradespeople to work on a roof without making it very expensive for you. Commercial buildings also tend to need more scaffolding to make it safe for the professionals to work, so some smaller roofing companies won’t offer commercial services. Make sure you check a company’s website or social media if you’re looking for commercial roofing – on the Quotatis Directory, our roofers will show whether they do commercial roofing to make your search easier.

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 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.
