A leaking roof can be a very annoying situation. Leak detection, too, can be hard. However, it can be tranquil when you are sure about what you are doing and have the right experience. In this article, we shall have a look at various methods of leak detection on roofs.
Electrical field vector mapping.
This method is appropriate for electrically grounded and electrically conductive roof decks like reinforced concrete and steel roofs. Homeowners may use this method on precast concrete slab roofs or wooden roofs if a conductive coating of metal mesh or foil is placed on the roof deck prior to the installation of the waterproofing layer. Therefore the decision to use this method has to be made at the designing stage.
Destructive testing is suitable for waterproofing membranes that are formed beforehand. You perforate the waterproofing membrane at the lowest segment of the roof deck to look out for any water that may be under the membrane. You must then repair the perforations you make through the waterproofing to retain the integrity of the membrane. Destructive testing may be the only detection method that you can use on ancient green roofs.
This method is only suitable for flat roofs that have slopes of up to 2 percent. The technique involves blocking the roof drains temporarily and then flooding the roof membrane with a specific depth of water for a period of time. You must check the weight loading of the roof against the weight of water that sits on your roof during flood test. This warrants that your building’s structural integrity is not compromised.
Electronic Leak Detection.
ELD is a non-destructive roof leak detection method used to find water leak entry areas and points of trapped water in low pitched roof construction or a flat. Utilizing electronically charged bristles is a non-intrusive roof leak detection method that can identify faulty points with maximum precision. The roof’s problematic areas are then marked clearly in order for a schedule of remedial works to occur. Without any guesswork in electronic leak detection, or the need to conduct flood testing, this roof leak detection method is harmless, eco-friendly, and accurate. click here for more roofing information…
Visiting the roof.
When you have a general idea of the area of your roof leaking, make time, and pay it a visit. Be sure to go up the roof when the area is dry, with non-skid shoes on. Check out for the indicators that you could have marked form the attic or the chimneys and vents. The indicators will help you in finding the leak on the outside.
Now, you may check your roof itself for missing, damaged or torn shingles, shingles with missing or damaged flashing curling corners, or other signs of damage. Have it in mind that if you spot a section with apparent indicators of damage, you can do something to protect your home as you wait for correction by covering the section using a tarp to keep your home from extra damage.
All the best, and good luck!
