There are plethora of ways to go about this but which method will best suit your concrete roof tile?

When it comes to working at heights, skill and confidence is paramount even if the actually cleaning and maintenance happens to be an easy task. As a result, if you lack the two attributes mentioned, we’d strongly recommend that you call in a professional roof cleaning contractor who can guarantee the best results for help. In this article, we aim to give you a good insight into the concrete roof tiles cleaning process. Let’s have a look!

✓ Use a trowel or stiff brush

This is a manual method which involves scraping off the algae, moss and dirt by hand using an effective tool like a trowel. However, before you do this make sure its a very dry day. Also, you can make use of a stiff brush to scrape off the dirt. Both cleaning tools are very easy and effective means to clean concrete roof tiles.

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.

As long as you can access them safely, it’s fairly easy to clean soffits and fascias. Using a sponge and warm water to scrub them is a good way to get off most types of dirt. You might want to add detergent or bleach to the water to make it more effective.

Once you’ve scrubbed your soffits and fascias, rinse them with clean water to make sure you’ve got all of the dirt and detergent off.

If your existing roof is still in good condition but the membrane is getting old, it’s often not worth exposing the structure to the weather whilst the contractor strips off the old membranes. The contractor will leave them in place to act as a base layer for a new roofing system. As long as there are no other problems with your roof, then overlaying is a good way to replace your flat roof.If you have any more questions about flat roofing that aren’t listed here, fill out our form to ask a contractor.

✓ Match your roof tiles perfectly. The most frequently used roof tiles are concrete and terracotta. They may look all similar but they can actually vary in shapes, length as well as thickness. To replace a broken tile, you must first make sure that it’s the same type of tile so it doesn’t interfere with the flow of your roof which can lead to further damage.

✓ Climb on to the roof. Make use of a strong and stable ladder to do this. If you’re not comfortable with heights, simply call in a professional. Falling of the roof would be more expensive.

✓ Remove the broken tile. Lift up the overlapping tile next to the broken tile in such a way to enable an easy removal of the broken one. If you’re not able to life them, then they probably have nails securing them in place. Remove these nails to proceed.

✓ Replace the broken tile with the new one. To do this, simply lift up the bottom tiles from the above row and then slide the new tile back in place. If the tiles have been nailed, make sure you also drive a nail through the hole in the new tile into the timber roof batten.

How you install commercial rubber roofing is similar to fitting it on a residential property, except that the area that’s covered is likely to be bigger. With commercial properties, you should always leave any maintenance and repair works to the professionals – whether you own or lease the property, you could invalidate any insurance if you try to install rubber roofing yourself. We’ll outline the steps roofers will take when installing rubber roofing on a commercial property.

Firstly, the installers will remove any existing coverings and clean and dry the surface thoroughly. This is vital in ensuring that the rubber will stick. They will then unwrap the EDPM rubber membrane and leave it to rest until it’s fully expanded. On a warm day this may take around half an hour.

Next, the roofers will work with half a sheet of rubber at a time and adhere it to the roof surface. They may use a water-based adhesive which they will spread onto the roof in sections, then roll the membrane onto the surface before moving onto the next section. If they’re using a bonded adhesive, they will apply it to both the roof and the rubber and leave it to dry until it’s tacky before extending the membrane.

Once the EDPM rubber is rolled out, the installers will brush the surface with a large broom to get rid of bubbles and provide a stronger bond. Then they will work of the edges, applying adhesive to roof and walls edges, sealing corners and creating watertight seals. They’ll also tidy up any excess membrane and seal all the trims.

As long as it’s installed correctly, your commercial rubber roofing should last you decades without any repairs needed. It’s always best to inspect your roof regularly to spot any damage before it becomes a bigger problem.

Do You Need Felt Under Roof Tiles?

Before now, roofing felt were mainly incorporated to serve as a temporary waterproof roof on a building which would later on be changed for the permanent solid tiles or slate roof. This is due to the fact that rebuilding a roof can be time consuming taking a few number of days, the roofing felt would be used to protect the structure as well as the property it contains by acting as a barrier between the house and the harsh elements such as rain, wind, snow, sleet and more, while also providing minimal insulation until the structure is complete.

However those are in the olden days, in recent times, roofing felt ( also referred to as breathable roofing membrane or breathable felt) is now being used to create a safe and waterproof roof which is long lasting and will protect your house, properties as well as other outbuildings for a long period of time while also complying with the Building Regulations. So to answer the question - yes, you’re going to need felt under roof tiles as it has been made mandatory by building regulations.

Now let’s take a look at the different functions served by felt.

✓ You’ll need felt under roof tiles to prevent the roof space from being exposed.

✓ Roofing felt protects homes where a roof has not yet been installed to serve as a temporary protective layer against the elements.

✓ Roofing felt is particularly crucial for modern homes which are constructed to be more energy efficient and work to hold warm air from escaping the house. This is great to reduce your heating bills while also keeping both you and your loved ones cosy all throughout the year.

✓ Overall, building regulations imply that an underlay underneath the slate or tiles is now a compulsory requirement.

In the UK, fireplaces are a very common addition to homes and property and reasonably so. Not only do they represent a great source of heat, but they’re also quite timeless in their beauty, thereby adding more value to your property. Now every fireplace possesses some sort of chimney, asides from the ones that are ventless. And while you might not be aware, every chimney poses a number of dangers which includes being a fire hazard and can also lead to carbon monoxide poisoning as a result of improper or lack maintenance.

Since your chimney will be clogged up over time with all sorts of soot and often cleaned from the top of the roof, cleaning of a chimney comes with a huge amount of risk. As a result, you run the risk of falling off if you decide to clean one by yourself. And even if you’re the type that’s comfortable being on high level places, you should know cleaning a chimney is not the most pleasant of jobs. It can be quite messy as accumulated creosote and soot can drop into your home causing a cloud which covers both the floor, furniture and any other thing you have in the room. Furthermore, chimney cleaning requires specialized skills and knowledge which professionals have acquired after several practices. For instance, missing out on a spot can result in an unchecked chimney fire or a masonry crack.

The simple answer to this question is, therefore, a big NO - you should leave the cleaning to the professionals.  Professionals are not just limited to chimney cleaning; they’re trained to identify any structural issues while also being able to carry out a close analysis of the chimney. They’ll fix minor issues on site and give you a peace mind for any future wood burning activities.
