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.

Keeping water away from your house is of great importance and hence, the installation of a roof guttering system to serve this purpose. However, in order to perform this task effectively and seamlessly, there’s a need to clear out the clogging dirt and debris from the gutter and ensure it’s free from water-blocking obstacles at all times. Although there are a number of ways to achieve this, but the major cause of concern for several home and property owners is having to work at heights or on top of a ladder to get the job done. This is a very dangerous endeavour especially if you do not have the confidence required to pull it off. As a result, we’d strongly recommend you hire the services of a reliable professional who possess the skills when it comes to working at heights and delivering a highly effective clean. Fortunately, there are a couple of ways you can get to clean your gutters without having to climb any ladders. Let’s take a look!

• Clean the gutter with a leaf blower. Several leaf blowers feature a nozzle attachment which is made to release a narrow stream of air which is suitable for cleaning of gutters. You don’t need a ladder to do the clean as a specialized attachment is available in order to increase the blower’s reach to your roof effortlessly. The final step would be to remove any lingering leaves or twigs using a hose.
• Clean the gutter with a wet or dry vacuum. For heavier debris, you can try out a wet or dry vacuum. To reach the obstructed gutters while standing on the ground, simply get curved attachments and hoses at a local home improvement store. You may, however, need to moisten some stubborn dirt before it can be properly vacuumed or removed.after completing the vacuuming process, simply flush the gutters with garden hose waters.

While it sounds like it could be difficult to plasterboard around a Velux window, it needn’t be. As long as you have the right tools and materials, you should be able to plasterboard around your roof window easily and make good ready to be skimmed. When you or a tradesperson has fitted your Velux window into your roof, you’ll probably need to plasterboard over it to create a good ceiling. To do this, you’ll need:

• Plasterboard sheets – make sure you measure your room so you know how much you’ll need
• Screws to secure the board in place
• Drill
• Hammer
• Straight edge and pen knife to score the board before trimming
• Fine toothed saw the cut the plasterboard

When you’re ready to plasterboard around your roof window, make sure you’ve cleared enough space to work in. Then you can begin by cutting your plasterboard to size using your straight edge and pen knife to score, then your saw to get a clean cut. A common way of plasterboarding around your Velux window is to use the groove on the window frame to hold one edge of the board, then screw the other edge to the battens on the ceiling. People often use drywall screws these days as they have a better grip of the plasterboard as they drive through. You’ll need to use a drill to screw these in. However, you could use plasterboard nails, which are galvanised to stop rusting. When you’ve done this, you can then skim the walls or ask a plasterer to do it for you. Plastering, while it looks easy, is a tricky skill so it’s always best to ask a professional to do it.

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.

How Much To Replace A Flat Roof

There’s no straight answer to this question. However, the average cost lies within the range of £1000 to £5000. This range may look too wide but the price is greatly influenced by a number of factors which is capable of making the price increase or decrease. Some of the factors affecting the cost of flat roof coverings and replacement include: the type of flat roofing system and materials you want, the area size of the flat roof in M2, the project’s location, the roofing company to be used, the ease at which to reach the roof, cost of removing the old flat roof as well as cost of removing the other waste.

Although there are many factors to be put into consideration but the most crucial factor is the size of the house or the area size of the flat roof in M2. for instance, a one bedroom apartment’s flat roof will have a price between £1500 to £3000. This is, however, with the assumption that the flat roof is going to be used as the main roof of the house. But if you’re only using it for a section of the house like your garage, the price could range between £700 to £1000

There four commonly used types of flat roof materials which includes fibreglass, felt, rubber and lead. If you need a felt roof, for example, the price is between £40 to £70 per m2. And in the same tone, a metal roof will generally cost more than a a flat roof made from rubber.

Another important factor we’ll discuss is the labour or the roofing company to be used. Different roofing companies will charge different prices. As a result, you should carefully compare the prices of the companies in order to get a great deal.

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.

You should inspect your roof twice a year, ideally after rain or snow, to see if it’s draining properly. Also in the Spring to check for damage that may of been caused over the winter months that will need to be put right before the next winter. Have an inspection carried out if you are unsure.
