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.

There is simply not one single answer when it comes to knowing how much would it cost to replace a commercial roof. Replacement costs is a variable which is dependent on several factors.
If you are looking to take a shot at guessing an estimate, you will first need to understand the what is need for the replacement.
YOUR COMMERCIAL ROOF IS AGEING
The first sign of replacement is definitely the age. Generally, roofs come with a warranty of twenty years. Based on your materials, the real lifespan for a commercial roof tends to be around 15 to 25 years. Depending on the maintenance and the materials, lifespan can be prolonged.
YOUR COMMERCIAL ROOF LOOKS TIRED
Compare your commercial property with other buildings in the area. If it looks pale and worn out in comparison, it is high time for replacement.
WATER DAMAGE
A sturdy roof should be able to withstand extreme weather conditions such as heavy rain or high winds. However, if a storm has caused significant damage to your roof, its structural integrity might be compromised. water damage is one of the most indicative signs for a roof replacement.
CRACKS AND HOLES IN ROOFING MATERIALS
Proper upkeep of the roofing materials is required for it to continue protecting your property. If you find any cracks or holes, bent tiles or sheets, replacing them is advisable.
SAGGING COMMERCIAL ROOF
Roof replacement is critical when your roof suffers from sagging or corrosion. Once sagging or corrosion begins, the structure becomes vulnerable to damage.
Keeping all the above factors in mind, replacing your commercial roof can range from anywhere around £10,900 to £44,000 depending on the materials you choose. Materials are available in the market from £35 to around £75 per square meter. If you chose higher or premium quality materials, price can range from £115 to £200 per square meter.
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.
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.
It can be a huge headache, but cleaning of gutters is a task that needs to be done and even more so when it’s a stained white gutter. Nobody want to do it, but everybody has to. If you happen to lack the required confidence to pull this off as it has to do with working at heights, then we’d strongly recommend that you get in touch with a reliable professional who can guarantee the best results for help and also save you some time and money from potential costly errors. In this post, we’re going to show you some of effective way in which you can tackle stained white gutters effectively.
Firstly, you’ll have to take out the ladder with a pair of rubber gloves. Simply position the ladder safely, climb up the roof and start removing the leaves and other debris clogging up the gutters. You can also make use of a garden trowel to remove the very thick debris. Once done, spray the gutter using a garden hose to flush out the dirt as this will make the stains visible. Then prior to cleaning, ensure to cover the plants or landscape underneath with tarp or plastic sheet since the cleaning solution may negatively impact the vegetation.
Start to clean by spraying an all-purpose cleaner on the stains and srub them off using a scrub brush. You can also try a mixture of 1/4 of water with 1 cup of bleach and 1 teaspoon of dish soap. Dip your scrub brush in this solution to scrub off the stains. The bleach mixture is guaranteed to eliminate any mold or mildew that growing on your gutters with ease.
It can be easy to repair a felt flat roof depending on the problem. If you’ve got an old-style pour-and-roll felt flat roof, you might be starting to run into problems, but even if you have a newer torch-on felt roof, issues can occur. You might find cracks, lifting, leaking flashings or dips and hollows in the felt. Luckily, there are some easy fixes – but the best thing to do to prolong the life of your felt flat roof is to get a professional to look at it.
If your felt flat roof only needs a small repair, you might be able to get away with using a paint-on fix from a tin that you just brush on. However, if you want a more permanent fix, you’ll need a few more tools and supplies.
You can use a patch of torched-on roofing felt over the crack or leak, but if your flat roof is very damaged or wet it might not take it. You can also buy liquid systems for felt roofs, but again, there is a possibility that your roof might not take it. Also most of the high-quality liquid systems are only available for trade customers, so you might be better off asking a roofing pro to do it for you.
In general, no – you don’t need planning permission for a Velux window. The Planning Portal says that you don’t need to apply for planning permission to install a roof window if the following conditions are met:
- A roof window must not protrude more than 150 millimetres above the existing roof plane No roof window or any other alteration can be higher than the highest part of the roof or stand out above the roof ridge
- Side-facing windows must have obscure glazing to protect privacy of neighbours and, if they open, they must be 1.7 metres above the floor of the room in which they are installed
You don’t need to apply for planning permission for a roof window because they are covered under permitted development rights. However, if you’re a leaseholder or you live in a building where your local authority has made an Article 4 Direction, you will have to apply. Usually, an Article 4 Direction is made when you live in a conservation area where any external home improvements could affect the character and look of the area. Luckily, there are special Velux windows that are designed to be more likely to be accepted by your local planning authority. They’re called conservation windows and, although there’s still no guarantee that they will be accepted, they are designed to look more traditional. Even if you don’t need planning permission for your roof window, you still need to follow any relevant building regulations for your local authority. The most important parts for Velux windows are section J and section L of building regulations, which refer to energy efficiency, thermal insulation and fire protection.
How Much Is A New Flat Roof
What is a home without a roof to keep out the elements? Being the first line of defence against intense sun, rain, wind and more, implies they require enough care and attention to keep them in a top condition. Therefore, whether you need a new flat roof or just to replace some tiles, you’d be interested in knowing how much it would cost you to get a new roof before you start making the necessary plans. Here, we’ll give you an idea on the cost of a new flat roof and how you can estimate yours based on your unique requirements.
The size of your roof as well as the material to be used are the two main determinants of any flat roof project’s cost. For instance, a four bedroom detached home’s slate roof will be more expensive than a felted flat roof for a small or standard garage. Generally, in the UK, the average cost for replacing a flat roof will range between £5000 to £6000. However, if you’re on a tight budget and looking for the cheapest possible option, you’ll get a felt flat roof only on a garage at about £1000 to £1500. Meanwhile if you want to replace the entire slate tiles of a large family home, the cost can jump up to a range of £11000 to £13000.
Other factors that plays a key role in the determination of a new flat roof’s cost includes the location, labour as well as materials. For instance, a new flat roof price is likely to be higher in London and the south east than the other regions of the country. Also, labour may cost you around £150 to £250 per worker on a daily basis.
