How to repair your flat garage roof will depend on what it’s made from. Lots of flat garage roofs are made from EDPM rubber, asphalt or felt. We’ll explain how to carry out repairs on your garage roof here. EDPM rubber flat roof repair EDPM rubber is an excellent choice for a flat garage roof and should need little maintenance. But if you do need to repair it, there are a few easy fixes. If it’s a small crack or tear, apply some lap sealant to the area, but don’t use too much. If you go for a more professional repair later, the sealant will need to be scraped off, so if there’s too much it might cost you more in labour. If you need to repair the flashing, buy some malleable flashing tape so you can form it into the right shape. Clean and dry the area that needs repairing, then apply an EDPM primer. When that’s touch dry, stick the patch of flashing tape down from the centre outwards with a roller. Repairing an asphalt flat garage roof Asphalt is also very hard-wearing, and when it does need fixing, the fixes often last a long time. So if you do get cracks or blisters, you can use a paint-on fix from a tin as a temporary repair. When it’s time for a more permanent fix, you can add a small patch of torched-on roofing felt or use a liquid system, but the high-quality ones are often only available to trade customers. How to repair a felt flat garage roof Felt can be repaired in a similar way to asphalt flat garage roofs. For small cracks or a temporary fix, try a paint-on treatment from a tin. But for something more permanent, use a patch of torched-on roofing felt or a liquid system. If these don’t stick, unfortunately it means it’s time for a new felt garage roof. If you do need a new flat garage roof, leave it to the professionals who will ensure that your new roof will last for years.

Knowing when best to clean your gutters can do a lot of good. Wile some people assume that fall is the best time for gutter cleaning after the leaves fall, others believe spring is the most appropriate time to clean the gutters before things start to grow there. The truth is, both camps are right. However, the best time to clean your gutters depend on a wide range of factors which are all unique to you. In order to help you make the most informed decision possible, we have created this post to help you figure out the right time to clean your gutters. Let’s take a look!
Where you’re located. What we get is four season in a year as well as as a good amount of rain. As a result, you may want to put into consideration cleaning your gutter at least twice a year - clean the gutters once in the spring and once in the fall. It’s important to make gutter cleaning a part of your normal spring schedule as well as part of your fall maintenance routines.
What surrounds your home. If you happen to have tree surrounding your home, then it’s more likely that dead leaves clog up your gutter pretty quickly. A single tree is enough as it’s going to shed leaves that will find their way into your gutter, accumulate and affect its performance and integrity.
What your gutter currently looks like. If you gutters already have an entire ecosystem of animal life and plants hamging over the edges, then the best time to clean the gutters is now rather than having to wait a particular season to act. A dirty gutter should be attended to immediately in order to prevent some unnecessary damages as well as expensive repairs.
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.
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. Simply tell us about your commercial roofing project and where the property is and we’ll put you in touch with up to 4 reputable commercial roofers that will be able to offer you a free, no-obligation quote. You can check out their reviews, qualifications, insurance and photos of work on their profile which we’ll send to you in an email when we’ve matched you. The roofing companies should contact you first, but if they don’t we’ll give you all their details so you can introduce yourself.
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.
If you’ve never had Velux windows before, you might be wondering how to open them. If you’ve got very high ceilings and your roof windows are set high up in the pitch of the roof, you might not even be able to reach them. So how do you open them in this case?
When Velux windows are installed so high that they’re out of reach, the installers will often recommend that they install an electric switch for you to open and close your windows. They often come with a rain sensor, so you don’t need to rush up to the top of the house if there’s a sudden downpour – they will close automatically. You can also choose to have a remote so you can open and close your roof windows wherever you are in the room.
If you don’t have an electric switch, but you still can’t reach to open and close your Velux windows, you should be supplied with a telescopic pole when they’re installed. If you weren’t or you’ve moved into a home with roof windows and there isn’t one, you can buy them online. They have a hook on the end and can be extended to the correct length so you can hook it over the handle of the window and pull or push to open it.
If you’ve got a top-hung Velux window that can also be opened in a centre-pivot position, it’s easy to switch between the two. Simply ensure the window is completely closed before you start, then open the handle up – but don’t push it out. Then pull the vent bar down until the sash is rotated 180 degrees. Then secure the position by sliding the barrel bolts into the holes at either side of the bottom of the frame. Easy!
Do You Need Felt Under Roof Tiles?
Before now, roofing felt were mainly incorporated to serve as a temporary waterproof roof on a building which would later on be changed for the permanent solid tiles or slate roof. This is due to the fact that rebuilding a roof can be time consuming taking a few number of days, the roofing felt would be used to protect the structure as well as the property it contains by acting as a barrier between the house and the harsh elements such as rain, wind, snow, sleet and more, while also providing minimal insulation until the structure is complete.
However those are in the olden days, in recent times, roofing felt ( also referred to as breathable roofing membrane or breathable felt) is now being used to create a safe and waterproof roof which is long lasting and will protect your house, properties as well as other outbuildings for a long period of time while also complying with the Building Regulations. So to answer the question - yes, you’re going to need felt under roof tiles as it has been made mandatory by building regulations.
Now let’s take a look at the different functions served by felt.
✓ You’ll need felt under roof tiles to prevent the roof space from being exposed.
✓ Roofing felt protects homes where a roof has not yet been installed to serve as a temporary protective layer against the elements.
✓ Roofing felt is particularly crucial for modern homes which are constructed to be more energy efficient and work to hold warm air from escaping the house. This is great to reduce your heating bills while also keeping both you and your loved ones cosy all throughout the year.
✓ Overall, building regulations imply that an underlay underneath the slate or tiles is now a compulsory requirement.
