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 Identify Asbestos Roof Tiles

Found in some particular rocks, asbestos is a naturally occurring mineral that’s commonly used before the 1990’s as a building material specifically for roofing. This material was banned in the UK as it was discovered to possess harmful fibres which is potentially dangerous to human’s respiratory health when disturbed and inhaled. According to several reports this health conditions include non cancerous lung disease, mesothelioma and asbestosis, which are all untreatable. Therefore, be it in a domestic or industrial setting, there’s the need to know how to identify asbestos and if found, start the removal process as quickly as possible.

While the three types of asbestos used in roof tiles can be quite easy to identify by themselves, a total reverse is the case, when mixed into a tile. Generally roofing tiles that includes asbestos will mostly have colours such as grey, white or blue-white colour, but so does several other roof tiles made from other materials that are totally safe. As a result, the only way in which you can identify if a tile contains asbestos is by looking for an identification mark. These marks are mostly inscribed onto about one in twenty tiles, therefore if you have a strong feeling that your roof tiles contains asbestos, you may have to remove several tiles before you can identify the marked one. Otherwise, the only way you can confirm is by sending a sample to a certified asbestos testing lab. These labs are knowledgeable and possess the right equipment, tools as well as testing kits to determine the levels of asbestos in your premises. With this, you have a better chance of getting quality results than any other means. What’s more? They’ll also recommend expert asbestos removal services if the harmful material is found to be present in your house.

How To Replace A Broken Roof Tile?

In this guide, we’re going to walk you through the processes involved in the replacement of broken tiles. Let’s have a look!

✓ 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 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 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.

An eave is the edge of a roof, which is why they are now and then called roof eaves. On a household's outside, eaves can stick out outside the side of the building, serving both ornamental and applied purposes. The eave of a house has come to mean the lower area of the roof that projects after the external covering, as opposite to a cornice, which is part of the entablature in Classical architecture.

Think of how a roof outspreads outside the covering, and then think about how a hard rain may roll down the roof and, on the ground, away from the structure. Centuries ago, the eavesdrop was that indentation line made around a structure when the rain fell off the edge of the roof onto the ground.

Types of Eaves

A roof can come to a conclusion in essentially three ways. A closed eave is the one which has very little or no overhang at all. An open eave has a visible overhang, projecting beyond the roof brackets. A boxed eave is surrounded with a soffit.

The Use of Eaves?

An eave can defend the siding and substance of a structure. A roof eave bulging beyond the sides permits snow and rain to fall from the roof away from the covering, to the ground. The more the "weather" gets thrown away from the household, the chances of you having a dry basement increases.

In cases of regions with a warmer climate, a large eave can help provide shade to the interior of the house. In rainy environments, the prolonged eaves of Asian architecture deliver shelter from the climate, as well as direction. In the 21st century, an eave may be an inconspicuous site for security cameras and light.
