Let's head to the lab, where we will conduct several experiment depicting successful capillary action, then capillarity which is inhibited by several factors. Now, the choice is yours! You can deal with capillary action on roofing systems yourself or hire professionals.Capillarity is defined as movement of a liquid along the surface of a solid caused by the attraction of molecules in the liquid to the molecules of the solid. Repairing a rusted roofing system is more difficult. It’s simple to block water from entering by capillary action. Investigate any dripping water within a building, particularly on the roof. Just because a new roof doesn’t imply, it isn’t prone to leaks. When dealing with a steel roof system, attentiveness is essential, just as it is with any other component of building care. External capillary action is no longer possible. Water will not be able to enter the spaces between the steel roof sheets due to this. Water ingress can be prevented by applying an exterior seal to the spaces where the roof sheets overlap. It settles, just like roof sheets, and starts the corrosion or rusting process. The area between the cladding overlaps allows moisture to seep in. When mixed wind and rain, the process takes on a new pumping dynamic. Way To Prevent Capillary Action On Steel RoofingĮven while it isn’t as widespread as it once was, it is still a concern when the right circumstances occur. Drip stop retains moisture until the temperature drops below the dew point, at which point it is released back into the air as regular humidity. Secondly, drip-stop can also help prevent surface tension because of the high density of metal or any other object on metal roofing.Ī drip-stop is a membrane designed to protect metal roofs from dripping or running condensation in high humidity and little ventilation buildings. Warm air condenses when it comes into touch with chilly surfaces and remains there. Spray Foam Insulation Aids in the Prevention of Mold and Moisture Most modern homeowners insulate their homes to keep mildew, mice, moisture, and dust out, as well as to keep air from coming in and out.

Similarly, surface tension occurs in metal roofing when water shrinks in small spaces such as pipes. In the case of surface tension, dense objects can float easily on liquid.įor example, a piece of metal can easily float on liquid because of its dense structure. Secondly, cohesion occurs when molecules of the same pattern cling to each other. The adhesion action takes place when different particles attract each other. When we talk or see capillary action in detail, you can clearly see that this process is consists of three actions, including cohesion, adhesion and surface tension. Moisture build-up on a steel roof will eventually lead to rust and leaks.

When the weather gets colder, though, it declines.Ĭapillary activity in untreated steel roofs will grow as global temperatures rise and climates become humid. In warmer, more humid situations, the process accelerates. Water will always migrate into a roof space by capillary action when allowed. It would be great to monitor these places regularly to ensure they’re still secure because roof panels can shift and migrate over time.

Sealing joints and overlaps with sealant or butyl tape prevents this. Even if the overlapping seam is above the underlying panel, it can cause a metal roof to leak at the joints. Because of the forces of adhesion, cohesion, and surface tension, water may be pushed upward against gravity.Ĭapillary action is the term for this procedure. When your roof is originally installed, it’s critical to seal these areas properly. On a metal roof, seams and overlaps are unavoidable.
