Protecting roofing systems from such threats as water or debris is essential in ensuring the sustainability of your home or commercial building. While shingles, tiles and other roof materials act as the outer cover of your roof, the one component that plays a huge role in preventing water penetration is flashing.
Roof flashing is like the guardian of your roof; it serves to protect your shingles and tiles from water possibly entering the joints. Like shingles and tiles, however, flashing may deteriorate over time and naturally require repair or replacement. Below are a few things to note.
When flashing requires replacement, proper procedures need to be followed to avoid further damage to your roof. Flashing is normally installed beneath the shingles and tiles, so removing these layers must be done carefully. The method of installing the flashing (e.g. secured by nails or adhesives) should be considered to determine how to remove them without denting or smashing other roof parts.
Upon removal of tiles or shingles, immediate replacement should follow to prevent exposure of the roof areas to the elements. Once these cover layers are removed, the damaged flashing must be cut quickly and replaced with the new material.
Installing new flashing requires correct measurements and definite application techniques, since it’s designed to prevent water infiltration. For instance, the new materials should at least overlap with the existing ones a few inches for proper fitting. Finding the most appropriate method with the help of Dallas roof repair professionals is important in securing the new pieces and finishing the replacement without hassle.
While replacement means you’ve already had a previous set of flashing installed, decide whether you need additional flashing in other parts of your roof. Before starting the whole project, identify roof areas where water may enter and include them in your flashing installation.
For two-story properties, step flashing is recommended to achieve the specific angle required between the shingles and the wall. Valley flashing is used for valley roofs, which tend to accumulate water or debris, especially after a downpour. Apron and chimney flashing, meanwhile, are done for roofs with dormers and chimneys, to protect the shingles and tiles around them as well.
Having your roof flashing replaced after some time would ensure your roof’s protection from natural damage. For the best results, hire professional Dallas, TX roofing companies such as G&G General Contractors.
