If you live in a house that was built before 1995, the chances are that the roof ridges are installed into place using cement and mortar. The disadvantage of cement and mortar is that the mixture is susceptible to cracking; therefore, it makes the insides of a roof prone to deterioration through water and moisture leaks. Consequently, you must repoint your roof to help seal the interiors from the elements. However, you should familiarise yourself with a few aspects before you decide to repoint your roof. Read on.

Full Glazed Terracotta Requires Special Advice -- Although it is advisable to call a roofing specialist for roof repointing services, you can still do it as a DIY. However, there are circumstances when the advice of a roofer is critical. One such instance is when you decide to use full-glazed terracotta roof tiles. Due to the glazed surface, you will find it challenging to get the repointing sealant to stick to the tiles' surface. Consequently, your tiles will not seal properly, thereby exposing the insides of your roof to leaks. Therefore, it is essential to seek the services of a roof specialist if you decide to use glazed terracotta tiles for your tile replacements. 

Apply Accelerant Spray -- When you decide to repoint your roof as a DIY project, you must ensure that you are up to date with the weather forecast. Repointing products don't do too well in wet conditions. Most homeowners, therefore, find it easier to reschedule the project for a later date when the sky is clear. However, you do not have to wait that long even if rain is in the forecast because you can use an accelerant spray. The spray does an excellent job of helping the repointing product dry quickly, thereby eliminating the chances of it being washed away by the rains. Most importantly, ensure the accelerant sealant you use is from a reputable manufacturer because of quality reasons. 

Roof Repoint on a Hot Day Is a No -- For most people, a sunny day might seem like the best time to undertake a roof repointing DIY project. The argument is based on the premise that high temperatures help repointing products dry faster. However, in as much as roof repointing products are designed to dry quickly, working on a roof on a sweltering day can be dangerous. Moreover, the repointing sealant will dry too fast, thereby denying you the opportunity to spread it evenly. Consequently, you will end up using too much repointing products. Choose a day with just enough cloud cover to protect you from the effects of direct sunlight. Additionally, you will manage to use the repointing products efficiently.
