How To Clean Moss Off Roof?

Although moss attack on your roof is a less common occurrence, but when they occur they can be very harmful to your asphalt shingles if not attended to. Generally, moss are commonly found in damp environments such as the North slopes, overhanging treses or overhanging regions of the roof which causes shade which enables moisture to be stagnant and moss to develop. If you observe a green fuzzy stuff appearing on your roof, that’s likely to be moss.

The same way algae navigated its way to your roof as they can be airborne and travel via wind, squirrels, birds or other little flying or climbing animals, moss also gets carried similarly. One moss finds its way up your roof, they’ll find spaces between the shingles where they’ll form thick spongy moss which can be difficult to clean off if you don’t know the best way to go about it.

If you’re not a competent DIYer or confident enough to carry out this task, we’d strongly recommend you hire the services of a professional who can guarantee the best results effortlessly.

The best way to go about the cleaning task for both your roof and environment is to incorporate a product called Spray and Forget or Wet and Forget. You can get these at most local hardware stores. Simply put the product into a hose end sprayer and can be applied from the ladder at the edge of the gutter or even from the ground. This method may take a up to 6 months before you’ll start seeing the results but it happens to be the safest. Another method that can be used is bleach and water which is very aggressive but provides a quicker result. However, this is best done by a professional to avoid seriously damaging your roof.

How Often Do Flat Roofs Need Replacing?

When a flat roof needs to be replaced is determined by a number of factors which includes the roof’s exposure to the weather, the condition and age of the roofing materials as well as the construction of the roof. However, with proper maintenance and regular inspection, they should be used for nothing less than 50 years. There are some commonly used types of flat roofs which includes Felt flat roof as well as a GRP flat roof.

Felt Flat Roof

The lifespan of a felt flat roof also varies depending on the quality and grade of the felt roof incorporated. This can make the roof last within the range of 2 to 20 years. More often than not, felt flat roofs are usually installed in such a way to keep the costs down which implies the grades of felts that are mostly used are the economical ones implying a very short lifespan.

In the event whereby a premium grade of felt is incorporated in constructing a roof by professional contractors, will be guaranteed by the manufacturer to last between 10 to 20 years.

One of the major causes of a short lifespan in felts is leaks which should be regularly inspected and repaired once identified. If not, the roof will gradually deteriorate and become a lot weaker due to the action of the sun. However, when a felt roof starts to leak, it’s usually a sign that’s approaching the end of its lifespan and a replacement should be taken into account.

GRP Flat Roof

The GRP flat roof or fibreglass flat roof usually comes with a manufacturer’s guarantee of 20 years and is expected to have a lifespan of a minimum of an additional 10 years.

Unlike felt roofs, they’re more resistant to leaks. However, they should also be regularly inspected for leaks which are caused mostly as a result of installation error rather than the GRP roofing approaching the end of its useful life. If the GRP roof repair does not totally resolve the leak, you should start considering a replacement.

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.

Will My Roof Leak With Missing Ridge Tiles?

Your roof is the first line of defence against the elements. Therefore, if you want your home protected at all times, there’s a need to ensure a professional inspection of your home at least once a year. However, there are certain issues that you do not have to wait for a professional to be able to spot by yourself. And an example of this includes a missing ridge tile. This issue is noticeable from the ground level while some tiles may even fall off and notifying you in the process. If you’re currently facing this kind of challenge, you’d probably want to know if the missing ridge tiles can cause your roof to leak. In this article, we aim to answer this question and more. Let’s take a look!

Firstly, there are a number of causes of missing tiles or slates and the most obvious is the weather. When the wind or rain gets very high, it can pull your tiles out of place and even more more, if they weren’t properly installed in the first place. Secondly, there’s also a chance that the nails may wear away. These are the nails that holds your ridge tiles in place, they can rust and wear away, hence leading to missing ridge tiles.

Therefore, the short answer to the question is yes, missing ridge tiles can cause your roof to leak. Even if it doesn’t leave a visible gap in your roof’s covering, it’ll create a break in the roof which weather can easily penetrate. And allowing this to happen makes the other tiles more susceptible to damage which won’t be good for the entire house as well as your pocket. Hence, once you notice a missing ridge tile ensure to have it replaced as soon as possible.

Blisters are most common on membrane roofing systems. Lots of contractors will tell you that if there are no signs of further damage, there might not be any need to repair flat roof blisters. They form when pockets of air or water get trapped between layers of the roof’s membrane or between the membrane and the frame. When the sun is out and it heats the pockets expand and stretch the membrane. If you do want to repair your flat roof blisters, there are a few ways to go about it.

If you have a membrane flat roof, cut away the membrane until you reach a place where the membrane is still stuck tightly to the roof. Reapply as many new membrane layers as you cut away over the blistered area. You might even need to do more. To make sure your patch remains watertight, you’ll need to leave at least 6 inches around the edges of the blister.

If you’ve got a felt roof, you can cut an X shape through the blister. Peel back the triangles that you’ve made and let the timber frame dry for a while (so don’t do this when rain is forecast!). Then, coat the area with lots of bitumen adhesive and leave it to dry until it feels tacky. Then press down the triangles of felt firmly into the adhesive.

After that, you’ll need to add more bitumen adhesive to the cuts you made. If you’ve got any spare roofing felt, cut a square that’s about 100mm bigger than the cuts then lay this over the adhesive. If you’ve not got any felt, it’s cheaper to use a self-adhesive flashing strip. Once you’ve laid the strip or patch over, seal the edges with more bitumen adhesive.

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 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.
