how to clean roof tiles?

How To Clean Roof Tiles?

If you’re a DIY person with a dirty roof tiles or just a homeowner who’s also a lover of knowledge, you may probably like to know how you can have your roof tiles cleaned. This is a very common question which often depends on the dirt or debris you’re dealing with as well as the type of roof you possess. Most often than not, if you own a traditional concrete or slate roof tiles, then you’re more likely to battle moss and or algae growth.

If you’re not a competent DIY person or do not have enough confidence to pull this off, then it’s advisable to hire the services of a professional who can guarantee the best results for help. In this article, you’ll learn how to go about cleaning your roof tiles. Let’s have a look!

✓ Consider Safety. When it comes to roof cleaning, you have to be very careful. They’re normally high up and any task that deals with height will usually require putting safety measures in place. Firstly, it’s important to be confident with heights and ladders, if not you’d have to find someone who is. And if you’re confident, there’s also the need to find someone who can help you hold the base of the ladder.

✓ Trim the trees. Nearby trees are usually a threat to any roof and also makes cleaning much harder. So it’s always wise to cut any overhanging branches before you proceed.

✓ Bleach or not to bleach. Although you have to be very careful using beach and water but it also happens to be one of the easiest DIY ways to clean your roof. You either stand about 4 feet away and rely on water pressure or clean down the tiles by hand.

✓ Try not to make use of a blaster.

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 fit a Velux window?

Velux windows actually refer to one brand of roof window, which are windows that sit in your roof space and allow light and ventilation into your loft. But how do you install a Velux window? If you’re a competent DIYer, it’s not as difficult as you might think.

You can normally install roof windows entirely from the inside, so you don’t need to get up on your roof or hire costly scaffolding. They come with detailed installation instructions, so as long as you follow them you shouldn’t have much trouble.

Before you start, you’ll need to read up on the Building Regulations and Planning Permission laws. Speak to your local Building Control department if you have any questions.

Firstly, prepare the opening by removing enough tiles or slates from the roof. There’s no need to go out on the roof – access them by cutting away the felt underneath which will give you access to the tiles and battens. Cut away one of the battens from under a tile, then you can slide all the tiles into the roof space. You’ll need to cut away the roof timbers to make the right size opening, then add more timbers to strengthen the ones that are left.

Next, remove the opening sash from the new roof window then fit the frame into the new opening using the brackets provided with the window. Then fit roof flashing between the new window and the roof so you don’t get any leaks. Then lay your tiles back in position around the new Velux window; you’ll probably have to cut some to shape which you can do with an angle grinder. Always cut them on the ground, not in position on the roof.

Lastly, fit the sash back onto the window and you’re done!

If this sounds like too much hard work, plenty of window installers will be able to help you fit a Velux window and will probably be able to provide a much cleaner finish.

What is the best commercial roofing material?
The best commercial roofing material for your building will depend on the size and type of roof you have as well as your budget. A lot of commercial buildings have flat roofs, but some have pitched roofs. These days, flat roofs are almost flat, but are usually built on a small slope so water can drain effectively. Pitched roofs are much steeper and are made using tiles or shingle. Our top choices for commercial flat roofs would be fibreglass or EDPM rubber. Both of these materials will set you back around £80-110 per square metre, making them some of the most expensive flat roof materials, but they’re strong and durable. A fibreglass roof consists of a cut glass fibre mat that is pressed on the roofing frame, then resin is poured and rolled over the roof before a topcoat is applied. An EDPM roof involves laying an EDPM rubber membrane on the roof surface then gluing it down and coating it with a contact adhesive. For pitched commercial roofs, our top material would be concrete tiles or metal. Concrete tiles will set you back anywhere between 40p and £2.90 per tile and they’re long-lasting and fire-resistant. However, they are heavy and can be susceptible to high winds. Metal roofs have been used for over 50 years and today’s modern systems are extremely strong and allow for structural or thermal movement. Aluminium roofs will cost between £40-75 per square metre, plus installation. These days, flat roofs are almost flat, but are usually built on a small slope so water can drain effectively.

For pitched commercial roofs, our top material would be concrete or clay tiles. Concrete tiles will set you back anywhere between 40p and £2.90 per tile and they’re long-lasting and fire-resistant. However, they are heavy and can be susceptible to high winds. Clay tiles cost as little as 50p to £2 each and can last over 50 years, but they are heavy so if your commercial roof isn’t already, it will need to be reinforced.

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.

do chimney liners need sweeping

Chimney liners are a very important component of the chimney, but the fact is most home and property owners either continue to overlook them or aren’t even aware of their existence. This is, however, quite understandable given the fact that they usually last a long period of time – more than 50 years. To ensure that they last that long, the question that arises is, do chimney liners need to be swept and cleaned? The short and simple answer to this question is yes, chimney liners definitely needs to be cleaned on a frequent basis. A chimney liner happens to be an essential part of your chimney. When it’s not cleaned, it tends to accumulate dust, soot and dirt which can give rise to a number of problems you’d rather want to avoid. Chimney liner are able to provide adequate protection to your flue but even at that the water, creosote and other contaminant build up can make the liner to deteriorate, and making it unsafe for usage. In other words, contrary to several belief, chimney liners do need the same amount of cleaning as chimneys without liners. Failure to sweep your chimney liners can give rise to the following problems:

  • Creosote buildup. If your main source of fire is wood, then you’ll definitely have creosote present in your chimney. This is highly combustible and its buildup may lead to fire outbreak.
  • Carbon monoxide poisoning. Carbon monoxide is said to be on the rise by NCBI and its primarily generated from heating systems which are terribly ventilated as a result of uncleaned or dirty chimneys.

Also, you can make use of a stiff brush to scrape off the dirt. Both cleaning tools are very easy and effective means to clean concrete roof tiles.

What effects the cost of a Sun Tunnel?

The cost for a sun tunnel is affected by 5 key factors:

  1. Tube size: Small areas or stairways can gain from a 10-inch size tube, whilst bigger rooms will require a bigger tube. The higher television size, the greater the price.
  2. Kind of tunnel and also roof type: You can pick from stiff or flexible tunnels and also domed or flat roofing system panels. Each choice will have a different price.
  3. Place: Where you stay in the country will certainly impact the price of your sun tunnel installation. Generally, the higher the living prices in your location, the greater the price of employing an expert will certainly be.
  4. Length of the tunnel: Longer tunnels will be charged at a greater price than their shorter equivalents so whether the tunnel runs from the roof to the 2nd or very first flooring will certainly impact the sun tunnel price.
  5. Ease of gain access to: Flexible tubes are fantastic for homes where sun tunnels do not run in a straight line from roofing to ceiling. The tubes can then be fitted around challenges in your loft space. Frustratingly, these alternatives do not allow as much light as stiff tubes and also due to their hard setup can be much more expensive.
