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.

How to repair a flat roof depends on the type of flat roof you have. We’ll talk about how to repair felt, asphalt, fibreglass and EDPM flat roofs yourself. But ultimately if you want the best finish, it’s best to ask a professional to repair your flat roof for you. Repairing a flat roof Whether you’ve got an old pour-and-roll type felt roof or a newer torch-on felt flat roof, you can get cracks, lifting around joints, leaks or dips. As a temporary measure, you can buy a special paint that you paint over cracks. For a more permanent repair, you can add a patch of torched-on felt or add a layer on top. Asphalt flat roof repair As your asphalt flat roof gets older, you may notice blisters, cracks or shrinkage and sagging around flashings. Again, you can use a paint on fix from a tin as a temporary repair, or add heat-applied flashing tape around flashing. For a more permanent fix you can use a liquid system, but many are only available to the trade market. You can also add a patch of torched-on roofing felt over a crack. How to repair a fibreglass (GRP) flat roof Fibreglass flat roofs are usually excellent, but problems can involve leaking flashing and cracks near upstands, trims or board joints. You can add acrylic sealant to cracks or holes for a good DIY repair, but a flashing problem is more difficult to fix. You’ll need to clean and sand the affected area of flashing, then laminate a 600g chopped strand mat into place, cure it and add a topcoat colour to match the roof. That sounds like a job better left to a specialist. EDPM rubber flat roof repair Rubber roofs often suffer from shrinkage when mechanical fixings haven’t been used near upstands, flashing leaks or holes or cuts. If you’ve got a small tear that you want to repair, you can add some lap sealant to the area – but use it sparingly. For a more permanent repair to flashing, buy some self-adhesive flashing that will mould into shape easily. Clean the area you want to repair, add EDPM primer, then stick the patch of flashing on from the centre outwards with a hard roller. You can add lap sealant around the edges if you want more protection from water.
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.
How To Clean A Fibreglass Roof?
If you have a dirty fibreglass roof or perhaps you’re just planning to have one installed on a newly constructed house, then you’d probably want to know the best way to have your fibreglass roof cleaned.
Generally, fibreglass roofs are of great quality and happens to be a lot more resistant to moisture, heat, water and even fire when compared to the other alternative flat roofing materials. As a result, they require just a little maintenance but this doesn’t mean they should be totally ignored. Truth be told, cleaning of a fibreglass roof is as easy as it get, however, when it comes to working at height, skill and confidence is paramount to guarantee your safety. If you lack any of these two qualities, then it’s highly recommended that you sought the services of a reliable roof cleaning contractor who can do the work safely and perfectly. If you’re able to clean and maintain your fibreglass roof as you should, you wouldn’t have to think about replacement for about 20 to 30 years.
Cleaning is simple and doesn’t take much time. Now let’s take a look at the process.
✓ Preparation. Hose down the vegetation around the area with water to protect them. Once done, mix a gallon of warm water with one quarter cup trisodium phosphate and 1 quart of bleach. Put this mixture into a garden sprayer and sweep any dirt or debris off the roof with a broom.
✓ Application. Spray the mixture over the fibreglass roof, ensuring that it gets to all the necessary corners where dirt may be hidden. Allow this applied solution to sit for up to 15 minutes to loosen the stubborn stains and dirts on the roof.
✓ Finishing. Spray cold water to wash down all the solutions. If there’s still some dirts, you can repeat the process till the fibreglass roof is entirely clean.
A roof is one of the most significant portions of any property and they’re also the single part of a structure most vulnerable to impairment from the elements. If your roof suffers substantial damage over time, maintenances and re-roofing charges can be expensive, time-consuming, and stressful which is why it is imperative to keep your roof in sound structural and aesthetic order.
If a tile has fallen off from the top of your roof – you can expect to pay around £70-£100 to replace it including a different tile fitted in its place. Replacing a hip roof will cost between £4,250 and £7,250, the cost varies if you have a single valley or a double valley on your roof. For a new gable roof, you should expect to pay around £3,250 to £5,250.
What does it cost to replace my roof?

• size of your roof
• type and size of the materials used
• shape and style of the roof
• If structural changes are required or not
• the roofing company hired
Tiled roof repair costs
If you are trying to prevent water from leaking inside your house for one or two tiles, then you can expect to pay between £100 to £200 to fix them and seal the leaks.

It’s relatively simple to remove a Velux window, whether it’s Velux-branded or is another brand of roof window. Here is a breakdown of the steps you’ll need to take to remove a roof window:
- Remove the sash (opening part) from the roof window frame. Usually there are screws in the hinges to loosen or a button to press and lift out.
- Next, remove the tiles or slates from around the window frame along with the flashing.
- Unscrew all the brackets around the window frame and lift out the frame.
It’s that simple! You can do all of this from inside your home – there's no need to climb on the roof. Removing the glass pane from a Velux window, for example if it has blown, is a more difficult job and should be left to a professional. It involves removing the sash from the roof window frame and then removing the surrounding parts of the sash to lift out the sealed unit. They will then place the new glazed unit into the sash frame before securing all the parts back onto the sash and fitting it back into the roof window frame.
Roof tiles should be replaced as soon as possible to ensure that your roof stays waterproof. Use crawl boards when replacing them to avoid damaging other tiles, if not ask a qualified roofer to carry out the work, particularly if the tiles are higher up.
