Roofer FAQs

Can I change a metal roof to tile?

The feasibility of this will depend on the roof’s strength, in particular its load bearing capabilities. This is simply because tiles are heavier than the metal sheeting. Normally a tiled roof will need to take a load capacity of 60kg per square metre. You will need a trusted roofing company to advise on this.

How to open Velux windows?

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!

will my roof leak with missing ridge tiles?

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 much does gutter cleaning cost?

Leaves, twigs and moss all have something in common which commonly frustrates house and homeowner - they are the 3 major materials that adversely impacts the correct performance of a roof guttering system. The major reason for water drainage issues for many houses as well as buildings are these natural products. Wondering just how some leaves as well as few branches can trigger such a big problem? Over time there'll be a progressive build up of the all-natural debris in your rain gutter system which begins to rot and also count on a thick as well as sloppy goo which blocks the flow of water in your water drainage. Consequently, there's the demand to make sure that your rain gutters are completely cleansed at least twice every year in order to protect against larger issues that can be triggered by the obstruction of a drain system.

 

So if you're thinking about obtaining your rain gutters cleaned by a specialist, you 'd probably want know simply exactly how it's going to set you back. Well, there's not uncomplicated and straightforward answer to this question as there are a number of variables that adds to the final cleaning expense of your rain gutters.

The variables that can affect gutter cleaning rate includes the sort of your home (such as a terraced, end of terraced, detached as well as semi detached houses) which has a differing seamless gutter cleaning rate greatly as a result of their dimension differences, the height of the building (if you call for the service for a building situated on the second floor of a building, this would certainly be a little bit higher than if it were to be on the first stage) as well as added requests.

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.

How long does it take to fix a roofing sheet on a commercial property?

How long it takes to fix a roofing sheet on a commercial property will depend on the size of your roof and how difficult access is. Corrugated iron roofing sheets are much easier to fit than other roofing materials such as clay tiles or EDPM rubber, so that will work in your favour.

The size of the team of the roofing company you engage will also make a difference. If they have a lot of tradespeople working on your roof with lots of experience, it will take less time, while if there are only a couple of people it will take longer.

In general, it should take between 1 and 3 days to fit roofing sheets on a commercial property. If you’re not having a full roof replacement, it may only take one day, whereas a completely new metal roof could take up to 3 days.
