There are a few reasons why commercial buildings often have flat roofs. Lots of people argue that flat roofs aren’t as attractive as pitched roofs, which is why it’s uncommon to see a residential property with an entirely flat roof. Lots of commercial buildings don’t need to look attractive, so go for flat roofs because they’re cheaper.

Flat roofs tend to be less expensive than pitched roofs, especially for large, broad commercial buildings. Some commercial buildings simply couldn’t have a pitched roof because their width would mean that the roof would have to be extremely high. Flat roofs are also cost-effective for commercial buildings because it means that air conditioning and ventilation units can go on the roof, saving space in and around the building.

Commercial buildings also often have flat roofs because they don’t need the loft space that residential properties need. If there’s no need for the space, it doesn’t make sense to spend more money on a pitched roof just to keep the attic space empty. Flat roofs also give the commercial building owner the opportunity to use the space as a smoking area for employees or give access to fire escapes to upper floors.

If you’re having a commercial property build, make sure you speak to the experts about the type of roof that is suitable for you. If you’re planning on having air conditioning or ventilation systems installed within the property, you might be best off with a flat roof – but if you need some extra storage space, a pitched roof might work best for you.

A roof serves as something which is so much more than just a top of a building. A roof delivers guard from the elements and precipitation, it also helps drain water from a structure, and helps to provide insulation to the structure allowing it to keep the interior of a building cool or warm, according to season.

There are several steps to building a roof

Mount the trusses.

This step requires the building’s wall frames to be completely level, square and plumb. If you are building the roof onto a building that is still a frame you must use ladders or scaffolding. Hoist the trusses onto the roof.

Install temporary braces.

You will need to install temporary braces that the trusses can rest on until the sheathing and permanent bracing are installed, this has to be done before you install the trusses. At the centre of the back wall, nail the bottom half of one two-by-six board that's 16 feet long to the top of the outside wall, making sure you fasten it to a stud.

Install the end trusses.

Install the two end trusses at the front and back of the building, making sure you affix them to the temporary bracing. The batten you take will have to be a bit longer than the distance will separate the trusses.

Install the standard trusses.

According to the instructions provided by the manufacturer, you will first need to install the first standard truss. You will also need to nail it to the batten from the first truss.

Sheath the roof.

Once your trusses permanently braced, you can begin with the sheathing of the roof. Starting from the bottom corner and moving across the bottom, the sheathing is installed lengthwise.

Install the roof cover.

Like the sheathing and underlayment procedures, the roof cover is installed lengthwise from the bottom up. The shingles should be staggered, and they should also overlap at the same time. You will need to work up to the ridge and use a ridge cap shingles to finish the ridge.

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 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.

How Much Does It Cost To Have Roof Cleaned?

If your roof is dirty, it’s highly recommended that you have it cleaned by a reliable and professional roof cleaning contractor who specializes in cleaning of all types of roofs rather than making it a DIY project or hiring an odd job man who is a jack of all trades. This is due to fact that major mistakes like incorporating inappropriate cleaning agents, pressure as well as wrong cleaning techniques can have a serious negative impact on your home while also putting in mind the several dangers that comes with working at height. However, when hiring a professional roof cleaning person or company, do make sure that the cleaner is fully insured, possesses the relevant training working at height and has the ability to operate access machinery. In other words, when it comes to roof cleaning where safety is the first priority, it shouldn’t always be about the price of the job but the quality of the service you’re going to receive.
