Roof Flashing Repair for Metal Roofs: Mistakes to Avoid Roof Flashing Repair for Metal Roofs: Mistakes to Avoid

To ensure that a property doesn’t suffer from damaging leaks, it may sometimes be necessary to undertake roof flashing repair. To ensure that the work is effective, it is essential to know how to carry out the work correctly. When completing the repair project, being aware of the mistakes to avoid will give you a roof that has sufficient weather proofing and is fit for its purpose.

Stage of Installation

The point in time at which you undertake the roof flashing repair is important, specifically when the roof itself also requires repair. It is not worthwhile completing repair of the flashing, when there is damage to the roof itself that needs to be rectified. Undertaking the work the wrong way around, can result in the benefit of the flashing becoming ineffective. Make sure that the roof is intact and requires no repair, before commencing any necessary work to the flashing, which should always come last.

One Size Fits All

Be aware that there are a number of different types of flashing available, and you must ensure that you use the correct one when undertaking roof flashing repair. For example, it is essential to seal the join where the chimney meets the roof, which will require what is known as step flashing. When fitting flashing around pipes, a specific type of pipe flashing is required, to ensure that there is no water ingress.

External Factors

Don’t believe that it is not necessary to take all conditions into account when undertaking roof flashing repair. If you live in an area that suffers a high level of rainfall, for example, it is prudent to choose flashing that will make this less of a problem. In this case, a drip edge on the flashing would be prudent, to prevent water from collecting on the underside of the fascia, causing mold and damage.  

Planning

It would be a mistake to simply get up on the roof and start your roof flashing repair, without being aware of exactly what to expect. Prior to undertaking any work, inspect the roof to determine the extent of the repair required, making a note of all the points where flashing needs to be installed. This will ensure that you obtain sufficient materials to complete the repair project. As part of the planning process, you should also familiarize yourself with the necessary steps for repair. Determine the correct flashing for the specific area that requires protection from water leakage, and identify the additional tools necessary to seal it in place, such as caulk and roofing cement.

Choose Type Carefully

There are a number of different metals that flashing can be made from, allowing you to choose the one most suitable for the type of roof that you are working on. Be aware that you will need to manipulate the metal during the course of roof flashing repair, which will be more difficult with a stiff metal. Opting for a metal such as aluminum, will enable you to get the movement you need to work the flashing around corners and edges.
