Five Biggest Mistakes in Waterproofing Your Roof
Perhaps the roof is the most battered part of the house. It is the part most exposed, its sole purpose is to keep the occupants safe from the elements. Overtime, the roof can get worn out and not just from harsh weather. There are literally plenty of reasons for a roof to breakdown in some parts and may require maintenance or upgrade, such as metal roof waterproofing, in order for it to keep performing at its best.
However, there are many of us who don’t know what steps to take regarding this and commit mistakes that lead to an even bigger problem. Listed below are the things to avoid in having metal roof waterproofing.
1. Believing that either the “black tar” or “waterproof paint” is enough.- Simply put, the black tar and waterproof paint are not enough. They may be able to provide minor relief, but neither will fully fill in for what your roof needs. Besides, the tar solution is more for damp proofing only, and not waterproofing.
2. Applying the method of “spot correction” - When there are leaks, the quick fix is just to apply some kind of sealant or waterproof cement on the spot where the leak is. Most of the times, cracks can be filled with caulking or plugging materials to stopper the flow. This is not enough, however. If you want your whole roof to be fixed, the best option is to waterproof the entire roof regardless of where the leaky holes could be found. To do this, one must clean the whole surface of the roof with a pressure washer. Then, if there are cracks, they must be filled with mortar or roofing cement followed by a good prime. The elastomeric seal must be applied to the whole roof once the prime is dry, followed by another coat in 24 hours.
3. Ignoring the waterproofing felt - Sometimes, when leaks appear and won’t go away no matter what corrective measures have been done to the roof, it means that the waterproofing felt must already be replaced. If your waterproofing felt is actually old, then the problem lies below the surface of the roof and must be addressed there.
4. Not identifying the source of the leak - One common practice is to immediately check and repair the area above where the leak is. However, the actual source of the leak may be somewhere else. Do not restrict your checks to the area just above the leak to avoid committing this error. You might want to check corners, drainage pipes, etc. Leaks may not even be visible on the surface.
5. Not seeking professional help - Sometimes, the damage can either be so extensive or complicated that DIY tricks might not be enough. If this should happen, immediately seek the help of professionals who know how to do metal roof waterproofing. Having an impaired roof can be stressful for the household, so instead of taking matters into your own hands, contact the people who know what to do.
