A leaky flat roof is one of those things every home and property owner would rather prefer to avoid. Not only can it be extremely frustrating to deal with, but it can also have a grave impact on the overall integrity and value of your property especially when things are not done properly. Generally, all leaky roofs pose serious problems, however, a leak in a flat roof is even a lot more complicated. Ranging from the quite simple repairs to the incredibly complex fixes, flat roof repair (also known as low slope roof repair) is be seriously problematic and at times, can call for a reconstruction which involves complicated roof insurance as well as an experienced professional support.

Flat roof repair consists of many different types. Cap sheet roofs possess layers of material glued together with hot asphalt, including a roll of mineral surface glue using asphalt to the top rather than gravel. The tar and gravel roofs also possess layers of material glued together with the help of hot asphalt, with the use of asphalt on top as well as gravel included in the asphalt. A modified bitumen roof possesses more strength when compared to a cap sheet roof or the conventional tar and gravel roof. This can be 2 or 3 plies, smooth or with a mineral surface, torched on, mopped on or self adhering. What’s more? A TPO roof is a single ply roof which is usually heat welded together. A PVC roof is also a single ply roof that’s heat welded together while an EPDM is a single ply roof that’s glued together. The foam roofs as well as various coatings are incorporated to reflect the sun’s UV rays and also to maintain and seal the roof.

Strong winds can cause extensive damage to unprotected rooftops and in fact tiles act as very suitable protection. The extra weight they provide is great at countering high wind loads and if anything is damaged during severe weather, replacing tiles is straight forward for professional roofers.When you compare this to lightweight materials there’s a significant difference. If you wish to have extra protection, experts recommended having sarking fitted.

How To Clean A Fibreglass Roof?

If you have a dirty fibreglass roof or perhaps you’re just planning to have one installed on a newly constructed house, then you’d probably want to know the best way to have your fibreglass roof cleaned.

Generally, fibreglass roofs are of great quality and happens to be a lot more resistant to moisture, heat, water and even fire when compared to the other alternative flat roofing materials. As a result, they require just a little maintenance but this doesn’t mean they should be totally ignored. Truth be told, cleaning of a fibreglass roof is as easy as it get, however, when it comes to working at height, skill and confidence is paramount to guarantee your safety. If you lack any of these two qualities, then it’s highly recommended that you sought the services of a reliable roof cleaning contractor who can do the work safely and perfectly. If you’re able to clean and maintain your fibreglass roof as you should, you wouldn’t have to think about replacement for about 20 to 30 years.

Cleaning is simple and doesn’t take much time. Now let’s take a look at the process.

✓ Preparation. Hose down the vegetation around the area with water to protect them. Once done, mix a gallon of warm water with one quarter cup trisodium phosphate and 1 quart of bleach. Put this mixture into a garden sprayer and sweep any dirt or debris off the roof with a broom.

✓ Application. Spray the mixture over the fibreglass roof, ensuring that it gets to all the necessary corners where dirt may be hidden. Allow this applied solution to sit for up to 15 minutes to loosen the stubborn stains and dirts on the roof.

✓ Finishing. Spray cold water to wash down all the solutions. If there’s still some dirts, you can repeat the process till the fibreglass roof is entirely clean.

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 repair a flat roof depends on the type of flat roof you have. We’ll talk about how to repair felt, asphalt, fibreglass and EDPM flat roofs yourself. But ultimately if you want the best finish, it’s best to ask a professional to repair your flat roof for you. Repairing a flat roof Whether you’ve got an old pour-and-roll type felt roof or a newer torch-on felt flat roof, you can get cracks, lifting around joints, leaks or dips. As a temporary measure, you can buy a special paint that you paint over cracks. For a more permanent repair, you can add a patch of torched-on felt or add a layer on top. Asphalt flat roof repair As your asphalt flat roof gets older, you may notice blisters, cracks or shrinkage and sagging around flashings. Again, you can use a paint on fix from a tin as a temporary repair, or add heat-applied flashing tape around flashing. For a more permanent fix you can use a liquid system, but many are only available to the trade market. You can also add a patch of torched-on roofing felt over a crack. How to repair a fibreglass (GRP) flat roof Fibreglass flat roofs are usually excellent, but problems can involve leaking flashing and cracks near upstands, trims or board joints. You can add acrylic sealant to cracks or holes for a good DIY repair, but a flashing problem is more difficult to fix. You’ll need to clean and sand the affected area of flashing, then laminate a 600g chopped strand mat into place, cure it and add a topcoat colour to match the roof. That sounds like a job better left to a specialist. EDPM rubber flat roof repair Rubber roofs often suffer from shrinkage when mechanical fixings haven’t been used near upstands, flashing leaks or holes or cuts. If you’ve got a small tear that you want to repair, you can add some lap sealant to the area – but use it sparingly. For a more permanent repair to flashing, buy some self-adhesive flashing that will mould into shape easily. Clean the area you want to repair, add EDPM primer, then stick the patch of flashing on from the centre outwards with a hard roller. You can add lap sealant around the edges if you want more protection from water.

How you install commercial rubber roofing is similar to fitting it on a residential property, except that the area that’s covered is likely to be bigger. With commercial properties, you should always leave any maintenance and repair works to the professionals – whether you own or lease the property, you could invalidate any insurance if you try to install rubber roofing yourself. We’ll outline the steps roofers will take when installing rubber roofing on a commercial property.

Firstly, the installers will remove any existing coverings and clean and dry the surface thoroughly. This is vital in ensuring that the rubber will stick. They will then unwrap the EDPM rubber membrane and leave it to rest until it’s fully expanded. On a warm day this may take around half an hour.

Next, the roofers will work with half a sheet of rubber at a time and adhere it to the roof surface. They may use a water-based adhesive which they will spread onto the roof in sections, then roll the membrane onto the surface before moving onto the next section. If they’re using a bonded adhesive, they will apply it to both the roof and the rubber and leave it to dry until it’s tacky before extending the membrane.

Once the EDPM rubber is rolled out, the installers will brush the surface with a large broom to get rid of bubbles and provide a stronger bond. Then they will work of the edges, applying adhesive to roof and walls edges, sealing corners and creating watertight seals. They’ll also tidy up any excess membrane and seal all the trims.

As long as it’s installed correctly, your commercial rubber roofing should last you decades without any repairs needed. It’s always best to inspect your roof regularly to spot any damage before it becomes a bigger problem.

A pitched roof is a type of roof that is defined to have a sloping surface that has an angle that is greater than 20 degrees. Pitched roofs offer a more classical appearance. They remain the most communal and effective answer in wet and cold weathers to guarantee all-out protection.

Eaves

In the roof, the lower part of the inclined roof which is prominent outside the external face of the wall. The chief purpose of eaves is to pour the rainwater from the roof straight on the exterior wall. It also provides protection from sunlight. Eaves are sometimes decorated to an architectural beauty.

Gable

The Three-sided higher part of the wall at the end of a ridge roof.

Flashing

A band of impermeable material, typically metal, used to eliminate water from the intersection between a roof covering and another part of the structure. Flashings are provided to stop moisture from inflowing the wall and roof through joints in copings, parapet wall, and other infiltrations through the roof plane.

Hip

The Hip is defined as the exterior angle, which is generally greater than 180 degrees, which is formed at the inclined ridge of the roof slopes.

Ridge

The ridge is defined as the horizontal intersection made by the rising roof surfaces that are inclined in opposite directions.

Purlins

Purlins are the horizontal members which are laid on the principal rafters which help to support the common rafter of a roof. This is usually done when the span is large. Purlins are made from wood or steel. The top surfaces of the purlins intend to be unvarying and plane.

Fascia

This is the wooden board that is fixed to the feet of the common rafter at eaves. The Fascia helps the lowest ends of the roof covering material to rest on it.

Rafter

One of the major structural components of a pitched roof is a rafter. The rafter generally begins for the support of the roof to the ridge or hip. The purlin is supported by equally spaced rafters used side by side.
