For all types of roofing repair, flashing is a vital component that ensures protection of the roof and assists in the maintenance of the structure. Flashing is made from materials such as asphalt, copper, stone, slate, wood, plastic, fibreglass and others. It is also used for decorative purposes on gazebos and porches, decks and on other structures. The basic purpose of flashing is to ensure that moisture and condensation do not collect on the roof or condensation pools on flat roof surfaces. Asphalt and clay roofing are the most common materials used for flashings. Asphalt flashings are the best solution when there is a small leak or drip on the roof.
First, identify the area on the roof where the problem is. Flashing can be repaired if you have an exact idea of the location of the leak. Use a screwdriver to mark the location first, and then use an adhesive measuring tape to measure the size of the leak. After you have the exact location, you can start to repair it. If it is a small leak, you may just need to apply sealant to the exposed portion of the area first and then fix the flashing in the next step.
Roofing repair is very difficult job and needs skilled labor to do the job properly. So, you have to be careful in choosing the roofing contractor. The roofing contractor must be licensed and bonded with the local or state board. The roofing contractor must also be able to provide you with a guarantee for the workmanship and durability of the roofing. Make sure that you choose a licensed and bonded contractor who can give you a warranty on the workmanship of the roofing and installing of the flashing.
The second step in replacing chimney flashing is to determine the extent of the damage. You can easily determine the extent of the damage using the naked eye. If the area is totally covered by the flashing and there are no access holes, you don’t have to replace the chimney flashing. If there are access holes but the flashing is not enough to cover the hole, you may have to replace some tiles on the roof.
The roofing contractors will suggest that two pieces of the flashing to be replaced. Two of the most common is the gable and base flashing. For small roof repairs, base flashing can be used. For larger roof repairs, gable flashing is used.
For small leaks, you can use the roofing cement nails. To install these nails, you need to stir the roofing cement for five to ten seconds to make the glue bond. Install the nails about one inch apart from each other. For medium-size roofing repairs, the two pieces of flashing should be installed side-by-side. Nails the lengths depending on the height of the roof.
For large scale roofing repairs, you may need to hire professional contractors. For repairing small leaks around flashing, the most common solution is to apply water inside the space and patch it with flashing. You can also use a water filled plastic pocket as a fixative. However, the repair may become weak after continuous application.
Another option is to apply a layer of sealing and patching compound on the roofing cement behind the flashing. It is best if you apply the patching compound directly on the leak area. After this repair, you should make sure that no additional water is leaking into your home. You should seal the patch as soon as possible to prevent additional water entry. Once your repair has been completed, you should check for the areas where moisture is leaking into your home.
