In seeking to waterproof your roof, first, you have to understand whether said waterproofing is required. Therefore, you have to first check what material your roof is made of. If your roof is made of concrete, then it is probably already waterproof all by itself. Therefore, only fractures in your roof will need to be further made waterproof. This will save you a substantial amount of work, as rather than having to coat your entire roof with waterproofing materials, you will only have to work on certain areas that may require a little more waterproofing or a little strengthening. Contractors will be able to advise you on whether your roof requires such waterproofing. However, in the case that you choose to undertake the whole operation by yourself, then here are some tips on how to completely waterproof your roof.
Firstly, you have to prepare your roof for the coating of your choice. Therefore, check your roof thoroughly for any damaged caulking or unevenly applied concrete. If your roof has cracks in it up to 0.6cm wide, fill them in with caulk. However, if the fractures in your roof are wider than that, you have to conduct concrete patching to fill in these joints. Ensure that the area is completely dry before proceeding. If the surface of your roof is rough, there is a good chance that the coating that you choose to apply on it will not adhere well. Therefore, you have to grind the roof with industrial sandpaper or otherwise so as to smoothen the surface and ensure better adherence. As part of your preparation, you should further clean your roof to make for the best possible results in waterproofing your roof. Give your roof a thorough scrub to get rid of any dirt that may remain on the concrete. Let your roof dry before waterproofing it.
There are many different types of materials available for waterproofing your roof. A liquid membrane has several benefits: it is both inexpensive and produces results at a rapid rate. Liquid membranes are coatings to be sprayed or rolled onto your roof directly, and therefore are easy to use. Liquid membranes, however, will make it difficult for you to achieve even coverage. Therefore, sections of your roof will be more thickly coated with liquid membrane than other parts of your roof. Should you choose a liquid membrane, follow the available instructions on how to apply it.
Another form of coating, a self-adhering sheet membrane is a large, rubberized asphalt membrane that you apply to your roof. Sheet membranes possess a benefit over liquid membranes in that they will allow you to achieve uniform thickness, but they are more expensive than liquid membranes. They also require greater skill in application as they are extremely sticky and you have to be careful in peeling the membrane to expose the sticky side, for they will stick upon contact with a surface and they are tough to remove from the surface once having bonded to it. You have to also mind how sheet membranes overlap, for improper laying of the sheet membrane will increase the propensity for leakages to occur in your roof. Ensure that lap joints are cut as per instructions and that a bead of mastic is run down every lap joint one foot from a corner. Sheet membranes are also not a one-person job, so you will have to find a partner willing to help you to avoid disappointment and a bad waterproofing job.
If you are searching for a more eco-friendly method of waterproofing your roof, I suggest that you select sodium bentonite, which is basically clay. It is able to bond to smooth as well as coarse surfaces and will function as a great waterproofing agent, given that clay has high porosity and can prevent water from seeping into your house. It is also healthier for the environment, given that clay is more biodegradable than the rest of the materials and the harvesting of it produces little waste.
