Roofer FAQs

How can I maintain my flat roof?

how much is it to replace a garage roof?

How Much Is It To Replace A Garage Roof?

The size of your garage will be the main determinant of the cost of a new garage roof. However, the present condition of your roof structure as well as the type of roof covering preferred are also huge factors. In the UK, the cost of a garage roof replacement will be within the range of £700 to £3600.

The first step a pro will take is to remove the existing roofing while also making sure that the timber structure is in a good condition. In the event whereby the timber is rotten, it will need to be replaced before the installation of a new roof. If the garage roof sheets needs a replacement, you’ll have to spend about £30 to £50 per each garage roof sheets. Individual plywood sheet has around 2.4m x 1.2m in measurement and whose price should also be included in the final cost.

The above information applies only to standard roofing for garage roofs with flat roofs being made of bitumen felt and asphalt. In recent times, this is no longer the case with several more options available. Today, EPDM and GRP fibreglass have rapidly become very popular amongst several homeowners in the country. It’s also important to note that modern roofing has greatly advanced over the years even though both EPDM garage roofs and GRP fibreglass garage roofs are way better and of more quality when compared to felt and asphalt roofs. And thanks to modern technology, modern garage roofing possesses a longer life expectancy and as result, are a lot costlier than the conventional ones.

For a medium size single garage (2.7m x 5.5m), the cost for a felt roof per square metre is between £40 to £70, while that of a fiberglass roof and an EPDM rubber roof is between £90 to £110 and £70 to £100 respectively.

how to clean a roof?

How To Clean A Roof?

If you’re planning to clean your roof, but don’t know where to start, you’ve come to the right place! There are different types of roofs available in the market today and the method used in cleaning one can be largely different from the other. As a result, we’re only going to look at one of the common types of roofs you’ll find in the UK - the Asphalt shingle roof tiles. This roof type is very common and for a good reason. Not only are they visually appealing but they’re also hugely versatile by design which enables them to be adaptable to varying shapes, angles as well as forms depending on your preference or needs. With all the benefits that can be derived from asphalt shingle, they however, need to be properly maintained to help retain their good looks.

To clean your asphalt shingles, you’ll most likely require some type of chemicals especially when dealing with algae stains and some other visual problems. Therefore, make sure you purchase a product marked safe to be used on this type of roof and not those only proven to remove moss and algae stains. Mix the chemical cleaner with a gallon of water and a quart of bleach or as instructed by the manufacturer. Pour the mixture inside a pump-style garden sprayer and mix thoroughly. When done, climb up on the roof and spray as good as you can. Upon completion of spraying the roof with the mixture, then allow to work its magic for some time - about 15 minutes or thereabout should be good.

After that, you can make use of a garden hose to spray down the roof and wash down the mixture entirely. If some stains remain, use a brush to gently wipe the tiles individually.

how often to sweep chimney on a wood burner

Chimneys are certainly on top of the commonly overlooked features when it comes to cleaning a house. This is quite understandable given the fact that they’re not readily accessible and not in plain sight, hence, home and property owners tend to overlook the relevance of any chimney cleaning effort. But this can be a grave mistake! The importance of having your chimney swept on a regular basis cannot be over emphasized and even more so if it happens to be on a wood burner. Not only can a dirty chimney constitute fire hazard, but when left uncleaned it can also give rise to blockages which can lead to carbon monoxide poisoning. In fact, from 2014 to 2018, one of the top factors contributing to about 25% of home heating fires is due to lack of cleaning, mainly from solid-fueled heating equipment, mostly chimneys. Therefore, sweeping your chimney regularly is a safety precaution and when they happen to be on a wood burner, this exercise becomes a lot more important. With that in mind, the question that arises is just how often is sweeping of a chimney on a would burner needed?

 

Well, it’s strongly advisable to sweep chimney on a wood burner at least twice a year by a qualified professional depending on the usage. If you happen to own an oil burning fireplace, the same also applies. In other words, this means that regardless of the type of chimney you possess, the cleaning must be done regularly. However, most chimney would only need to be swept once in a year by a qualified professional.

why do roof tiles slip?

Why Do Roof Tiles Slip?

Despite being our first line of defence against the elements and covering the most valuable assets we possess, it’s shocking the reason why most roofs go unnoticed for years. However, when a damp patch suddenly appears on the ceiling or water starts to leak into our home, the condition of our roofing suddenly becomes of huge importance to homeowners.

In the UK, we get a fair share of harsh wind and heavy rainfall across the year which over time can lead to a plethora of roofing issues. One of the most obvious to identify is when roof tiles slip. If you’re also facing the same challenge, then you’ll most likely be interested in knowing the reason behind this occurrence. In this article, we’re going to take a look at some of the reasons why roof tiles slip.

Roof tiles can slip as a result of a corrosion of the nails that’s in place to secure your tiles to your roof. This happens especially during strong storms, whereby several roof tiles can be dislodged by rain and winds. If the affected tiles are just a few, then it may actually be a little issue to resolve. However, there are also times that the tiles slippage can be caused by a more serious issue. What’s more? You can also discover slipped roof tiles if the wood of your roof is corroded or weak. However, this applies a lot more to older homes than new or recent constructions. Any of the above reasons may be the main cause of your roof tiles slippage, but if you really want to know the exact cause for sure, you’ll have to call in a professional roof company to inspect your home.

how to clean moss off roof?

How To Clean Moss Off Roof?

Although moss attack on your roof is a less common occurrence, but when they occur they can be very harmful to your asphalt shingles if not attended to. Generally, moss are commonly found in damp environments such as the North slopes, overhanging treses or overhanging regions of the roof which causes shade which enables moisture to be stagnant and moss to develop. If you observe a green fuzzy stuff appearing on your roof, that’s likely to be moss.

The same way algae navigated its way to your roof as they can be airborne and travel via wind, squirrels, birds or other little flying or climbing animals, moss also gets carried similarly. One moss finds its way up your roof, they’ll find spaces between the shingles where they’ll form thick spongy moss which can be difficult to clean off if you don’t know the best way to go about it.

If you’re not a competent DIYer or confident enough to carry out this task, we’d strongly recommend you hire the services of a professional who can guarantee the best results effortlessly.

The best way to go about the cleaning task for both your roof and environment is to incorporate a product called Spray and Forget or Wet and Forget. You can get these at most local hardware stores. Simply put the product into a hose end sprayer and can be applied from the ladder at the edge of the gutter or even from the ground. This method may take a up to 6 months before you’ll start seeing the results but it happens to be the safest. Another method that can be used is bleach and water which is very aggressive but provides a quicker result. However, this is best done by a professional to avoid seriously damaging your roof.

How to repair a hole in a flat roof?

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.
