If you are a homeowner or a commercial building owner that has a flat roof you can have serious roof problems occur that are very difficult to repair without the proper knowledge.
Flat Roof Repair can be very trick in a flat roof because it can be very difficult to track down the leak source on the top roof surface. A Flat roofs leak can actually be many feet away from where it is entering your building which means that everything between the leak and where it is leaking in is taking on some sort of water damage that has to be fixed before it is to late.
There are a few ways you can handle the situation. The most expensive of course would be a total tear off of the damaged roof surface. This can break the bank and is not always the best option, flat roofs lives can be extended for many years with the proper care and maintenance.
The best way to extend the life of the roof is to apply a roof coating to the surface, these come in a few different types. There are asphalt based and polymer or elastomeric based coatings available today. Both can extend the life of your roof but the elastomeric roof coatings will give you a better quality roof surface.
Asphalt base come in a liquid form that is generally black and petroleom based. If you are going to use this product be sure to buy one that has a warranty and that has fiberglass embedded fibers throughout it. These type of roof coatings should only be used over a asphalt based roof such as felt or modified bitumen. They can be used on a metal roof but they generally do not work well on these surfaces. There are some roof coatings that have aluminium flakes in it to give a certain level of sunlight reflectivity to help reduce the roofs overall surface temperature thus saving you money on your cooling expenses.
Elastomeric roof coatings are generally rubber based and also come in a liquid form. They are generally white in color but can be mixed with colorants to obtain a desired look. Elastomeric Roof coatings are much better than asphalt based because of there ability to stretch, some of the better brands as much as 600%. This gives you a wide variety of roof problems that can be resolved with this type of coating. Elastomerics can be used on metal roofs, asphalt roofs, concrete roofs and some can be used on rubber roofs. Another nice feature about elastomeric coatings that are white is that they can greatly reduce roof temperature, which in turn should save you money on your energy bills. So over time the roof actually pays for itself in just the energy savings alone.
Both of these will give you a seamless roof that should be leak free if applied correctly. Roof coatings do not work alone, there is alot of prep work that must be done in order to apply the coating. Fasteners need to individually sealed, seams need to be reinforced, flashing’s need to checked and reinforced and yo need to start with a clean surface which that alone can take a lot of time to complete.
So as you can see there is alot to consider when choosing a roof coating solution, if you are unsure you should hire a qualified roofing contractor to do the work for you and be sure that they follow the correct steps to ensure your roof is sealed tight.
If you own an old commercial building with a flat roof odds are you have an old asphalt roof of some type. These roof surfaces are made up of layers of felt paper and tar stacked up on each other which over the years will or have given you alot of headaches. They are usually just felt paper or the are covered with a layer of gravel, the gravel in theory was to help keep the roof cooler which it does a little but it makes repair much more difficult.
One of the biggest problem with asphalt surfaces is that they dry up and shrink which eventually leads to cracking and this will cause your roof to leak. In order to keep your asphalt roof in good condition it must be maintained. To accomplish this you should have your roof re-coated with an asphalt based coating at least once every five years or so, if you don’t it can lead to expensive and time consuming repairs. Over the years your roofs crucial oils are weathered out of the roof surface and it must be restored to maintain integrity, if you have areas with standing water then the process speeds up and your roof will fail in that area most likely first.
If you are on of the unfortunates owners of a gravel roof then you can have even bigger problems. Gravel was put on in a time when it was thought it would be beneficial to help reduce the roofs temperature with cheap gravel, it worked a little but not very much. Gravel roofs undergo the same problems as a regular felt roof but the leaks and standing water areas are much harder to spot. Another huge problem is maintaining the roof, in order to do a maintenance coating all the gravel must be removed. Sounds easier than what it is, you should contract out a gravel suction company to complete this task, but if you are feeling like you need a good workout a few flat shovels and a broom will do the job as well.
Another problem that asphalt roofs face are blistering problems. Blistering occurs when moisture works it way in between the roof layers and expands forming a huge gas pocket, eventually these pockets will expand to a breaking point and crack open, thus leaving you with a hole in your roof. If you have blistering problems you must cut them open with a cross cut so you can fold back the edges and fill them in with roof cement, then fold the cut edges back over the cement thus resealing your roof.
There are a few types of roof coatings that can be used to remedy and repair your roof problems. The most commonly used are asphalt based but if you want a better longer lasting coating you should consider using a elastomeric roof coating, they are much more durable, more energy efficient and longer lasting than asphalt coatings.
Asphalt coatings are generally black or silver in color and have a life span of about five years if appleid correctly. They are generally the cheapest of the roof coatings but if you decide to go with this system be sure to purchase ones that are fiberglass embedded, they are much better at stopping and repairing leaks.
Elastomeric coatings are generally white in color and have a life span of 10 to twenty years, there are a few with a 20 year warranty as well, but they are very expensive. Elastomeric roof coatings work very well especially when combined with fiberglass mesh system as its base.
