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 a flat roof costs to repair depends on a few factors. Is your flat roof on a garage or an extension? What is the flat roof made from? It’s always best to get a few quotes to compare prices, but we’ll give you a rough idea here. If your flat roof was installed in the 1990s or earlier, it’s likely that you’ll see some leaks or damage soon. Felt flat roofs used to be installed completely flat, which meant that water couldn’t run off. That means that water pools and can create moss and damp. Sun exposure can also damage the felt, causing damage and eventually holes that lead to leaks. If you’re lucky enough to have got away with just needing a flat roof repair, this should set you back an average of £100 per square metre. If your roof is sagging due to the weight of it putting pressure on the timber frame, you might need additional joists – which could cost anywhere between £1,000 and £2,000, depending on how many you need. But if the problem is due to the internal part of the roof system becoming waterlogged, you could be looking at over £5,000. If your roof is severely leaking or the timber joists are rotting, it might be more cost effective to replace your flat roof. If you keep forking out for repairs, it will eventually be cheaper just to replace the whole thing, which could cost around £2,000.

How to repair a hole in a flat roof depends on what material your flat roof is made from. If you have an asphalt, felt or EDPM rubber roof, the repairs are quite simple, whereas it’s a bit more tricky if you have a fibreglass flat roof. How to repair a hole in an asphalt flat roof If you’ve got a small hole in your asphalt flat roof, you might get away with using a paint-on fix from a tin. It’s best to use this as a temporary measure to tide you over until you can get in touch with a professional. If the hole is on the flashing, you can add heat-applied flashing tape to it, or use a patch of torched-on roofing felt. There are liquid systems you can use, but usually they’re only available to the trade. Repairing a hole in a felt flat roof It's a similar process to asphalt roofing if you want to repair a hole in a felt flat roof. Use a paint-on fix for a temporary solution, but the best way to repair a hole is to use a torched-on piece of roofing felt to cover the hole and make it watertight again. How to fix a hole in an EDPM rubber flat roof If the hole in a rubber flat roof is small, you may be able to get away with applying some lap sealant to the hole. Only use a small amount, as if you go for a more permanent repair later down the line all of this will need to be scraped off. You can also use a malleable piece of self-adhesive flashing – clean the area, add EDPM primer and stick the patch on from the centre outwards. Add sealant to the edges if you want to give it more water protection. How to fix pin holes in a fibreglass flat roof If you find pin holes in your fibreglass roof, it usually means there wasn’t enough resin used at installation. To repair the holes, you’ll need to sand down the entire roof back to the clear resin. Then clean the area with acetone and apply GRP roofing resin – the acetone ensures that the resin sticks. You might need two coats of resin to get rid of all the holes.

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.
