In most of the cases of condensation under roof sheeting, it is the condensation on the roof sheathing that poses a problem. This is because condensation on the roof can act as a latent heat source for the roof. When it comes to this kind of roof repair, you have to be extremely careful because condensation can act like a latent heat source because it does not readily react with the air that is present. The condensation can remain stuck to the roof even when there is high humidity on the roof.
So how do you determine if there is a moisture problem? Well, condensation occurs due to the accumulation of water vapour on the roof surface. If there is sufficient water vapour accumulation, you will find that there is a wet feeling on your skin. If the water vapour is present in the open air, then it will be impossible for you to notice the dampness or feel the moist air.
Sometimes condensation occurs on the roof sheets directly. This can be caused by snow, ice or rainwater that has gathered on the roof sheets over night. If this is the case, you will have to remove and replace the snow, ice or rainwater on the roof sheets before you are able to start removing the condensation from underneath the roof sheets. However, the condensation that is already there can be removed easily if you know how to effectively and efficiently remove it.
When you are removing the moisture from the roof sheeting, you will need to make use of a vapour barrier. First of all, you should try to clean the moisture off the roof sheeting using a high pressure hose. You can make use of any commercial cleaning product that you would find inside your home. Then, use warm water and a sponge mop or a garden strainer in order to extract as much of the liquid as you can. Do not wipe or rinse the excess water off the roof sheeting. Instead, allow it to dry up naturally by leaving it outside to evaporate.
You should then apply a roof coating or roof sheathing membrane to the roof cavity. When you apply roof coating or roof sheathing membrane, make sure that it is sealed properly so that no moisture can escape from the roof cavity. This is to ensure that there is no condensation on the roof. However, even when you seal the roof cavity, condensation will still form on the roof sheeting if you do not close the roof cavity tightly. You will have to make sure that you do close the roof cavity tightly to prevent water vapour from escaping from the roof cavity through the roof sheeting.
Once you have sealed the roof sheeting, you can use roof insulation to prevent condensation on the roof. In fact, it is easier to install a roof insulation than to repair or replace the roof after condensation has formed on the roof sheeting. However, if you are not skilled at the installation of insulation, you can always hire a professional to do this work for you. The first thing that you will have to do is to open the box that comes with the insulation and lay down the felt pads.
Now, you have to place the insulation blanket and the felt pads across the roof. It is important that you do not leave any gap between the two. If any gap exists, the vapour barrier will be ineffective and condensation will form easily. Next, you have to stick the vapour barrier to the roof. Of course, it is a good idea to make sure that you follow the instructions on the packaging of the insulation blankets and the insulation materials that you use.
