How To Clean Algae Off Roof Shingles

Stains and dirt on asphalt shingles can only make your entire house look shabby which can go a long way to hide away the true value of your building. In some cases, dirts and stains on asphalt roofing shingles are nothing more than a cosmetic issue. However, there are also times in which it goes far beyond this - when the stains are indicators of a problem that if ignored, can result in a serious roof damage and ultimately, roof failure. In most cases, it’s usually hard to distinguish these stains and hence, the more reason why your asphalt roofing shingles should be regularly cleaned and maintained. In this article, we’re going to look at how you can get rid of algae of your roof shingles.

Algae growth on roof usually have either blue, green or black stains. They normally begin with little spots which will develop into streaks overtime. These stains are mostly mistaken for moss or mildew and aren’t harmful to any other thing than the roof shingles. However, the look it gives the entire house is something nobody enjoys.

It should be noted that this is a task that deals with working at height and requires skills and confidence to pull off. If you lack any of these qualities, simply reach out to a professional for help.

✓ Safety first. Put on protective clothing.

✓ Apply a bleach solution with a garden sprayer and let it sit for up to 20 minutes

✓ Rinse the roof thereafter with the stream from the hose (do not use a pressure washer as it can damage the roof shingles)

✓ If there are still algae left after rinsing with water, you can make use of a brush with medium-stiff bristles to gently scrub the stains off. If some stains are still left, simply let the roof dry before repeating the process again.

How Much Does Roof Repair Cost?

With the typical British weather, the roof is always subjected to enough battering every single day. With that type of events, you’d expect to find some chimney pots on the floor or roof tiles to go missing every once in a while. When these minor roof issues occur, a professional roofer is always in hand to easily resolve these problems. However, there are times in which the roof will be in a terrible condition with persistent leaks which is beyond the capacity of a roofer to resolve. In such cases, you may have to consider having the roof replaced as the best choice.

If you’re currently facing some issues with your roof and you need it repaired, then you’d probably want to know just how much it’ll cost to complete the project. In the UK, a roof repair cost can be within the range of £100 to £12,000 based on a number of influencing factors such as where the property is located as well as the size of the property. For instance, if you happen to stay in London where the demand is higher and there’s also the high cost of living, roof repair costs tend to be a bit more costly.

Let’s look at a simple breakdown of some roof repair jobs. These includes the following:

✓ Cost of renovating the roof on a detached four bedroom house using slate ( two story house) will range between £6300 to £12000.

✓ Cost of renovating the roof on a two story semi detached house using slate will range between £5000 to £7400.

✓ Cost of renovating full roof on a two bedroom bungalow using slate will range between £4000 to £5900.

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.

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.

Competent Roofer is a scheme that allows professionals to self-certify that their work is in line with Building Regulations. If you don’t use a registered Competent Roofer, you’ll have to pay your local authority to certify the work, so we recommend you use a Competent Roofer to save yourself extra outlay at the end.

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 Much Are Roof Tiles?

The way your roof looks speak volumes about your home or property. When you have an attractive roof installed, you give a huge impression of how beautiful the interior of your house is.

Roof tiles are the prefect roofing material if you wish to have your house looking elegant and decent. However, what turns off most homeowners about roof tiles is the belief that the prices are not budget friendly. This is absolutely false and in this article, we’re going to give you a rough estimate of the cost of roof tiles.

The price of roof tiles includes the cost of removing and getting rid of the old roofing materials, the cost of purchasing new roof tiles in the market as well as the cost of installing them on your house. There are a plethora of factors that affects the cost of roof tiles. These factors include the height and size of the roof, the roof’s design, the roof’s pitch, incidental costs of labour, the company hired as well as your location. What’s more? A roof with a complicated design such as hips and valleys will also generally cost more than simpler ones. Also, if you happen to reside in a place like London with higher cost of living and greater demand, the cost is also likely to be higher than other regions. As a result, providing an accurate cost of roof tiles is simply not possible.

Generally, the cost of having an entire roof retiled will cost within the range of £10,000 to about £20,000. For a more accurate estimate, you’ll have to identify reputable roofing professionals within your local area and find the roof tile prices that perfectly suits your budget.

How To Clean A Roof?

If you’re planning to clean your roof, but don’t know where to start, you’ve come to the right place! There are different types of roofs available in the market today and the method used in cleaning one can be largely different from the other. As a result, we’re only going to look at one of the common types of roofs you’ll find in the UK - the Asphalt shingle roof tiles. This roof type is very common and for a good reason. Not only are they visually appealing but they’re also hugely versatile by design which enables them to be adaptable to varying shapes, angles as well as forms depending on your preference or needs. With all the benefits that can be derived from asphalt shingle, they however, need to be properly maintained to help retain their good looks.

To clean your asphalt shingles, you’ll most likely require some type of chemicals especially when dealing with algae stains and some other visual problems. Therefore, make sure you purchase a product marked safe to be used on this type of roof and not those only proven to remove moss and algae stains. Mix the chemical cleaner with a gallon of water and a quart of bleach or as instructed by the manufacturer. Pour the mixture inside a pump-style garden sprayer and mix thoroughly. When done, climb up on the roof and spray as good as you can. Upon completion of spraying the roof with the mixture, then allow to work its magic for some time - about 15 minutes or thereabout should be good.

After that, you can make use of a garden hose to spray down the roof and wash down the mixture entirely. If some stains remain, use a brush to gently wipe the tiles individually.
