Roofer FAQs

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 slate a roof?

One of the most popular choices for roofing materials are roof slates. There is a number of advantages that a roof slate has, hey can be aesthetically pleasing, they can also increase the potential selling value of the house and many more. Slate is a sturdy and resilient material that delivers waterproofing physical characteristics to a pitched roof. Unlike other roof materials which absorb water slates do not. Therefore, slate is the most resistant towards freezing and water damage.

Find out the pitch of your roof

Before beginning with the fitting procedure, you need to figure out the pitch of your roof. The roof pitch commands how much overlap is essential with each slate. This has been made a lot easier than the early days with the advancement of technology.

Find out the required overlap

Once you’ve found out the exact pitch of your roof accurately, take a look at the slate producer’s description. Each manufacturer will propose the obligatory overlap in order to form a firm and safe slate roof.

Roll out the roof membrane

Firstly, guarantee your joists or trusses are clean of any sheards or old nails that could harm the membrane. You will now have to roll the chosen roofing membrane along the roof trusses. It is always wise to start from one of the bottom corners and keep rolling it along to the other corner.

Secure the roof membrane

Once the membrane has been moved out, use thump nails to protect one edge. You will now have to pull the membrane taut and carefully fix it into position. Do this before adding any nails across the membrane at points of intersection with the trusses for extra stability.

Batten placement

This is done to find the proper assignment of the battens. For this, you will need two full-sized slates along with an under eaves slate. Carefully position the battens on the top of the roof on the top of the overlay. Make sure not to fix them down since it will be easier to move them around and make any adjustments.

How to fit a velux window into a slate roof?

Fitting a Velux window into a slate roof is very similar to the way you’d install it in other roof types. All roof windows, whether a Velux-branded one or not, will come with detailed instructions for you to follow if you want to have a go at fitting it yourself. But here are some brief instructions to give you an idea of what’s involved in installing a Velux window into a slate roof:

  1. After you’ve removed the Velux window from its packaging, remove the sash (the part that opens) from the frame, according to the manufacturer’s instructions.
  2. Next, you need to prepare the opening for the window. You can often cut through the felt, remove one of the battens from under a slate, then slide all the slate tiles into the roof space. You should then make the cut 40-60mm wider than the window, cutting away roof timbers then replacing them with more around the opening to strengthen it.
  3. The roof window’s bottom brackets need to be installed on one of the existing battens for the slate roof. One of the slate courses should line up 105mm below the top edge of the batten you use.
  4. Then, measure from the top edge of the batten upwards to the height of the window plus 45mm. This is where the top installation batten should be installed, with an overhang of 100mm on each side.
  5. Remove the course of slates below the window, trim any excess felt and fold it over the surrounding timber. This helps with waterproofing.
  6. Add the insulation collar according to the Velux window manufacturer’s instructions.
  7. Place the frame in the opening, adding the brackets according to the instructions. You’ll find that lots of roof windows have pre-drilled holes to make it easy for you.
  8. Replace the sash and line up the hinges. Take a look at the opening at the bottom between the sash and the frame – it should be even along the entire width. Remove the sash again to fix the upper brackets according to instructions.
  9. Add the underfelt collar for your roof window as instructed by the manufacturer, then replace any slates at the bottom. You might need to cut them to size.
  10. Next, add the flashing according to the instructions, along with any parts that are not yet attached, including the hood section and top flashing piece.
  11. Replace all the slates around the window, allowing 60-100mm of space between the course of slates above the window and the top of the window to allow for rainwater drainage. Then replace the sash into the frame again.
  12. Add the vapour barrier on the inside of the window using the screws provided, then tape it to the existing vapour barrier to prevent moisture from reaching your roof structure.

And that’s it! If you think that sounds a bit complicated, ask a roofer or window installer to fit your roof window into a slate roof for you. You’ll get a better finish and you can be sure that you won’t get any leaks from a botched installation.

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.

what happens if you don't clean your gutters?

Gutters are a crucial component of any roofing system. They’re designed in such a way to protect your home or property from serious water damage, but keeping them clean and in good condition is something that’s almost always forgotten or ignored. Do not be deceived even when rain water is still running from them or they don’t appear to be clogged. Failure to clean maintain your gutters can lead to a wide range of outcomes and they aren’t so pretty. According to experts, gutter cleaning should be done twice a year - once in the spring and once in the fall. In order to help you realize the importance of cleaning your gutters, we’ll look at some of the possible outcomes of a neglected gutter.

  • Leaky roof. If your gutters get clogged and cannot move water away from your home, it begins to build up on the roof and eventually lead to damages like rot and mold. As the damages spread, the end result could be a severe damage to the attic and supports.
  • Damaged foundation. If the gutters are not functioning as they should, water saturation becomes a great threat to the foundation of your home or property. The concrete will crack or wood rots and you can also end up with mold.
  • Creepy crawler infestation. Wherever you have stagnant water, there are also bugs. This is because they love the wet and moisture-filled gutters. You get unwanted visitors like carpenter ants, roaches and mosquitoes, just to mention a few.
  • Driveway and path damage. When the downspouts aren’t directing the water to the appropriate spot, the excess that comes in contact with these surfaces can lead to cracks or sagging.
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.
