Most people will tell you that the health of their property depends on the state of the property's foundation. However, if you look at it from a roofer's point of view, a healthy roof is crucial to the stability of the rest of the house. It is especially the case if your home is older and the roof features cement mortar on its pointing. The reason is that cement cracks over time and the roof tiles tend to loosen or shift, thereby creating gaps. Hence, roof repointing is necessary, and your choice of repointing ingredients is crucial. Flexible roof repointing compounds have become the go-to repointing materials for roofers. Read on to find out the reasons.
Available in a Variety of Colors
When it is time to repoint your roof, cement and mortar restrict you to a handful of colours. It is mainly the case if you do not intend to paint the roof after the repairs. However, if you want the repointed sections to have the colour of the tiles, then your roofer needs to wait for the cement to dry before painting. Not only does this take time, but it also adds to the overall cost of the repairs. Flexible pointing compounds that are available to roofers today come in a variety of standard and designer roof colours. All your roofer needs to do is apply the pre-mixed pointing mixture in your colour of choice. There is no need to repaint the repointed sections.
Roofers are often careful when choosing roof repointing projects, especially during winter or when there is a storm. The reason is that cement and mortar need at least 48 hours to cure adequately before any paint can be added to the surface. Moreover, the slow drying process means that the area should be protected to prevent damage, especially if the repointed section is near tree branches. The quick-drying capabilities of flexible pointing compounds eliminate these issues since the compounds dry up within 5 hours. Therefore, you don't have to worry about protecting the repointed tiles from further damage once the mixed compounds are applied.
One primary issue homeowners have with standard roof repointing materials is their inability to withstand the sun's ultraviolet rays. It is the reason why roof colours tend to fade over time and crack during extreme weather changes. It is a problem you don't have to deal with by using flexible pointing compounds. It is because the structure of the compounds allows for flexible expansion and contraction. Therefore, chances of cracking are eliminated, and the colour pigments on the repaired parts are not be broken down by the sun's harsh ultraviolet rays.
