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 Replace Flat Roof Felt

Also referred to as tar paper, roofing felt is installed underneath the roof’s shingles to help deny water access to your home. Installing the roofing felt in overlapping layers builds a water barrier in situations whereby the weather damages or blows away the shingles. Although the application of a roofing felt on a flat roof is relatively easier and safer than working on a peaked roof, it’s advisable to take enough care and precautions. If you lack proper training and experience for this task, we’d recommend you employ a reliable professional to guarantee the best results and save you from further headaches especially in cases whereby unfortunate errors are made. This step by step guide will give you a good insight into the flat roof felt replacement process.

• Take a measurement of the width and length of the roof.

• Calculate the square footage by multiplying the numbers.

• Multiply the square footage gotten by three (it’s advisable to install three layers of roofing felt to create a really strong weather barrier).

• Use a claw hammer to remove the existing roofing felt.

• Use utility knife to cut the new felt to fit the length of the roof.

• Place the first piece along the roof’s edge and use a hammer tacker to tack the felt in place with staples or galvanized nails and hammer.

• Put the staples or nails at every 6 inches along the side touching the roof’s edge as well as down the short sides.

• Repeat the same process for the second piece, laying it out beside the first row of felt.

• Cut a piece of felt to the appropriate length using a utility knife to begin the second layer of roofing felt, and cutting it in half, lengthwise.

• Apply construction adhesive along the first row using a trowel.

• Press the first piece for the second layer onto the adhesive. Repeat this process until the roof is covered with a second layer

• Apply construction adhesive over the second layer to install the third layer. Begin with a full piece of felt without cutting it in half.

• Overlap each piece by 2 inches until you’ve completely installed the third layer.

Yes – you can repair a flat roof in the winter. Contractors will still be able to help you repair leaks, and it’s a myth that they will charge more. Most won’t have any additional costs just for coming out in the winter.

You'll have to wait for any snow and ice to melt before you can repair your flat roof. Depending on what type of flat roof you have, some repairs might have to wait until temperatures reach a certain level above freezing – some coating products won’t adhere (stick) in low temperatures, but a roofing professional will be able to advise you on what is best to use in the winter. If you have an EDPM rubber roof, most of the adhesives won’t mix in cold weather, so you might have to wait until temperatures rise to get a proper repair to your flat roof.

The best way to avoid needing to repair your flat roof in the winter is to inspect it at regular intervals. During the summer, even in the UK’s mild weather, the sun’s UV rays can damage and weaken flat roof surfaces, potentially causing cracks and holes. As autumn approaches, take a look at your flat roof and see if you notice anything untoward. If you do, speak to a reputable roofer who can repair your flat roof for you before winter arrives.

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.

Fibreglass, or GRP, flat roofs are very durable and should last you years, but over time they can become brittle and you might see some cracks or holes forming. Luckily, you can repair a fibreglass flat roof and it doesn’t have to be too difficult. Cracks in a fibreglass flat roof If you notice long cracks in your fibreglass roof, you can often use a fibreglass crack sealant. Simply clean the area, squeeze the sealant into the crack, then smooth it off. If you want it to look neater, you could coat the entire roof with a restorative coating which will make it look new again. Hole in a fibreglass roof If you notice a hole in your fibreglass flat roof, you’ll want to get this repaired as soon as possible to avoid any rainwater getting into your home. There are lots of fibreglass roof hole repair kits on the market, both online and in DIY stores, so you shouldn’t have trouble picking one up. They usually contain a mouldable UV cured patch that you can stick onto the hole. It will harden and become instantly weatherproof, so is the perfect emergency repair solution. Fixing pin holes in a fibreglass flat roof Unfortunately, if you find pin holes in a fibreglass flat roof it’s often because the installer didn’t use enough resin during the fibreglassing process. Luckily, if you can’t get back in touch with the installer or you only notice after a few years, you can fix this yourself. Sand down the roof back to the clear resin layer. Clean the entire roof with acetone and reapply some GRP roofing resin. Ensure that all the pinholes are filled – you might need two coats.

Yes, it’s a dirty job, but every homeowner out there has got to do it! Your gutter needs to be free of dead leaves, birds’ nest and other debris as well as being through clean in order to perform its functions effectively. It’s just a part of the responsibilities that comes with owning a home. Dry leaves, tree branches and other materials build up in your gutters overtime especially during the dry summer and you won’t notice until the point where your gutters start overflowing during the first main rain of the season.

In the event whereby your dirty and clogged gutter is left unattended to, this can lead to several issues like a leaky gutter and mold, leaky roof and basements,cracked foundation, driveway and yard damage and several more which will definitely make you incur more unnecessary expenses. So the question is, how often should the gutters be cleaned? The answer is, it depends. According to several experts, gutters should be cleaned at least twice a year - which is once in the late spring and once in the late summer or early fall. However, there are a couple of factors that may make you have a rethink.

If you happen to have a pine tree growing above your house, it’ll be wise to consider inspecting your gutters every 3 months. This is because pine trees shed needles year-round and they usually have a lot of these needles to shed. In the situation whereby you’re located at a higher elevation, ice is will most likely be your greatest source of concern. Making sure that your gutters remain clean throughout the winter can be quite a headache, but damage to your roof cause by ice can be an even greater pain. Prevention is always better than cure.

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.

Whether you’re liable for a leaking roof in a commercial property will depend on your ownership status and any contracts. Of course, if you own a standalone commercial property, it would make it your responsibility to repair to leaking roof. But if you own an office within a building, you should check your paperwork to see whether you are responsible for some or all of a leaking roof.

If you’re a tenant in a commercial property, things get a bit more complicated. Lots of commercial leases are FRI, or Full Repairing and Insuring leases, which means that the tenant is responsible for all external and internal maintenance and insuring the building. It means that it’s vital that you read through your tenancy agreement in full before signing it and seek legal advice if you think you need it. If your lease is an FRI lease, you are liable for a leaking roof in your commercial property.

It’s important to ensure that you have a schedule of condition for the property, which will mean that you only have to restore the commercial property back to the condition that it was in when you took over. It’s also worth getting the roof inspected before you sign the lease, as if there is any damage before you sign the landlord may be responsible.

The best way to avoid having to pay for a leaking roof in a commercial property is prevention. If you are liable for repairs and maintenance, make sure you have the roof inspected regularly by a reputable company to avoid having to pay for costly repairs when disaster strikes.
