how to clean algae off roof shingles?

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 to clean roof lights?

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.

What is a pitched roof?

A pitched roof is a type of roof that is defined to have a sloping surface that has an angle that is greater than 20 degrees. Pitched roofs offer a more classical appearance. They remain the most communal and effective answer in wet and cold weathers to guarantee all-out protection.

Eaves

In the roof, the lower part of the inclined roof which is prominent outside the external face of the wall. The chief purpose of eaves is to pour the rainwater from the roof straight on the exterior wall. It also provides protection from sunlight. Eaves are sometimes decorated to an architectural beauty.

Gable

The Three-sided higher part of the wall at the end of a ridge roof.

Flashing

A band of impermeable material, typically metal, used to eliminate water from the intersection between a roof covering and another part of the structure. Flashings are provided to stop moisture from inflowing the wall and roof through joints in copings, parapet wall, and other infiltrations through the roof plane.

Hip

The Hip is defined as the exterior angle, which is generally greater than 180 degrees, which is formed at the inclined ridge of the roof slopes.

Ridge

The ridge is defined as the horizontal intersection made by the rising roof surfaces that are inclined in opposite directions.

Purlins

Purlins are the horizontal members which are laid on the principal rafters which help to support the common rafter of a roof. This is usually done when the span is large. Purlins are made from wood or steel. The top surfaces of the purlins intend to be unvarying and plane.

Fascia

This is the wooden board that is fixed to the feet of the common rafter at eaves. The Fascia helps the lowest ends of the roof covering material to rest on it.

Rafter

One of the major structural components of a pitched roof is a rafter. The rafter generally begins for the support of the roof to the ridge or hip. The purlin is supported by equally spaced rafters used side by side.

How long should a flat roof last?

It depends on the material you use, but if your flat roof is installed correctly it should last for at least 10 years, and at least 20 if a material other than felt is used. Always question a roofing company when they quote to find out what materials they use and what guarantee's they offer.

why do roof tiles slip?

Why Do Roof Tiles Slip?

Despite being our first line of defence against the elements and covering the most valuable assets we possess, it’s shocking the reason why most roofs go unnoticed for years. However, when a damp patch suddenly appears on the ceiling or water starts to leak into our home, the condition of our roofing suddenly becomes of huge importance to homeowners.

In the UK, we get a fair share of harsh wind and heavy rainfall across the year which over time can lead to a plethora of roofing issues. One of the most obvious to identify is when roof tiles slip. If you’re also facing the same challenge, then you’ll most likely be interested in knowing the reason behind this occurrence. In this article, we’re going to take a look at some of the reasons why roof tiles slip.

Roof tiles can slip as a result of a corrosion of the nails that’s in place to secure your tiles to your roof. This happens especially during strong storms, whereby several roof tiles can be dislodged by rain and winds. If the affected tiles are just a few, then it may actually be a little issue to resolve. However, there are also times that the tiles slippage can be caused by a more serious issue. What’s more? You can also discover slipped roof tiles if the wood of your roof is corroded or weak. However, this applies a lot more to older homes than new or recent constructions. Any of the above reasons may be the main cause of your roof tiles slippage, but if you really want to know the exact cause for sure, you’ll have to call in a professional roof company to inspect your home.

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.
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.
