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.

A roof serves as something which is so much more than just a top of a building. A roof delivers guard from the elements and precipitation, it also helps drain water from a structure, and helps to provide insulation to the structure allowing it to keep the interior of a building cool or warm, according to season.
There are several steps to building a roof
Mount the trusses.
This step requires the building’s wall frames to be completely level, square and plumb. If you are building the roof onto a building that is still a frame you must use ladders or scaffolding. Hoist the trusses onto the roof.
Install temporary braces.
You will need to install temporary braces that the trusses can rest on until the sheathing and permanent bracing are installed, this has to be done before you install the trusses. At the centre of the back wall, nail the bottom half of one two-by-six board that's 16 feet long to the top of the outside wall, making sure you fasten it to a stud.
Install the end trusses.
Install the two end trusses at the front and back of the building, making sure you affix them to the temporary bracing. The batten you take will have to be a bit longer than the distance will separate the trusses.
Install the standard trusses.
According to the instructions provided by the manufacturer, you will first need to install the first standard truss. You will also need to nail it to the batten from the first truss.
Sheath the roof.
Once your trusses permanently braced, you can begin with the sheathing of the roof. Starting from the bottom corner and moving across the bottom, the sheathing is installed lengthwise.
Install the roof cover.
Like the sheathing and underlayment procedures, the roof cover is installed lengthwise from the bottom up. The shingles should be staggered, and they should also overlap at the same time. You will need to work up to the ridge and use a ridge cap shingles to finish the ridge.
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.
To find a commercial roofer near you, you could ask other tenants or property owners whether they can recommend a company. If you choose a company that’s been recommended to you, make sure you do your own research into them before you decide to engage them; you can check whether they have social media pages, reviews and examples of previous work. If the company has a Quotatis profile, you’ll find genuine reviews from their customers there, including photos of work they’ve completed.
Another option is to do your own search online. These days lots of companies will have their own website and you may be able to make an enquiry through there without even having to call them. Again, you should always check out their qualifications, previous work and reviews before deciding to go with them.
Or, you could let Quotatis do the work for you.

The cost for a sun tunnel is affected by 5 key factors:
- Tube size: Small areas or stairways can gain from a 10-inch size tube, whilst bigger rooms will require a bigger tube. The higher television size, the greater the price.
- Kind of tunnel and also roof type: You can pick from stiff or flexible tunnels and also domed or flat roofing system panels. Each choice will have a different price.
- Place: Where you stay in the country will certainly impact the price of your sun tunnel installation. Generally, the higher the living prices in your location, the greater the price of employing an expert will certainly be.
- Length of the tunnel: Longer tunnels will be charged at a greater price than their shorter equivalents so whether the tunnel runs from the roof to the 2nd or very first flooring will certainly impact the sun tunnel price.
- Ease of gain access to: Flexible tubes are fantastic for homes where sun tunnels do not run in a straight line from roofing to ceiling. The tubes can then be fitted around challenges in your loft space. Frustratingly, these alternatives do not allow as much light as stiff tubes and also due to their hard setup can be much more expensive.
How Much Does Roof Repair Cost?
With the typical British weather, the roof is always subjected to enough battering every single day. With that type of events, you’d expect to find some chimney pots on the floor or roof tiles to go missing every once in a while. When these minor roof issues occur, a professional roofer is always in hand to easily resolve these problems. However, there are times in which the roof will be in a terrible condition with persistent leaks which is beyond the capacity of a roofer to resolve. In such cases, you may have to consider having the roof replaced as the best choice.
If you’re currently facing some issues with your roof and you need it repaired, then you’d probably want to know just how much it’ll cost to complete the project. In the UK, a roof repair cost can be within the range of £100 to £12,000 based on a number of influencing factors such as where the property is located as well as the size of the property. For instance, if you happen to stay in London where the demand is higher and there’s also the high cost of living, roof repair costs tend to be a bit more costly.
Let’s look at a simple breakdown of some roof repair jobs. These includes the following:
✓ Cost of renovating the roof on a detached four bedroom house using slate ( two story house) will range between £6300 to £12000.
✓ Cost of renovating the roof on a two story semi detached house using slate will range between £5000 to £7400.
✓ Cost of renovating full roof on a two bedroom bungalow using slate will range between £4000 to £5900.
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 Velux window is a brand of roof window, but the brand is so popular that people often use the name to describe the entire type of window. They are windows that are installed at the same orientation and ‘in plane’ with the surrounding roof, and they’re usually installed at a minimum of a 15-degree pitch. You can buy roof windows that offer completely frameless internal views for a really clean look in your loft conversion, while some come with built-in shutters.
Velux windows aren’t to be confused with rooflights which usually refers to a glazed unit that’s installed on a flat roof. It might also mean a window that’s been installed on a pitched roof out of plane with the level of the tiling.
People also confuse roof windows with skylights, which normally can’t be opened or closed and are usually smaller than Velux windows. Skylights, therefore, only let daylight into the room whereas roof windows also help with ventilation.
If you’re using your loft as a room in your home rather than simply for storage, you must have a roof window installed. Skylights won’t be enough as they don’t allow for ventilation. It doesn’t have to be a Velux window – it can be any type of roof window. Luckily, they tend to come in standard sizes and they must be CE marked if they’re sold as a roof window, so they should be easy to find.
