Waterproofing a roof is absolutely essential. Before you can do that, however, you need to know how best to work with whatever type of material your roof is made from. For instance, concrete roofs may not require waterproofing since they already do a great job of repelling water. The only exception is if the concrete becomes cracked. In that case, you may need to seal the cracks or apply a waterproofing membrane to prevent water from getting inside.
Carefully evaluating the current condition of your roof can help you determine whether or not waterproofing is necessary. If it is, you can then decide whether you just need to patch certain areas of the roof or whether you need to treat the whole thing. Once you have a plan in place, it is simply a matter of applying the waterproofing materials in accordance with the manufacturer’s directions. If you are planning on waterproofing your roof yourself, try using the following tips.
Begin by preparing the surface of the roof. Different types of waterproof coatings or membranes require different preparation techniques. In almost all cases, however, you will need to remove any debris from the surface of the roof. You will also need to remove any old caulk. Check for cracks in the surface of the concrete. If you find any that are up to about half a centimeter wide, use caulk to fill them. Cracks that are wider than that should be repaired using a patching material that is specifically designed for concrete. Before you continue with the waterproofing process, allow the patches to thoroughly dry.
Most roof coatings adhere best to smooth surfaces. If the surface of your roof is too rough, you may find it beneficial to smooth it out using industrial-grade sandpaper. If you do sand your roof, be sure to wash away any dust or debris using a power washer or hose. Again, make sure that your roof is thoroughly dry before proceeding.
Although there are a lot of different waterproofing on the market, liquid membranes are some of the most effective. Not only are they relatively affordable but they also are fast and easy to apply. Depending on your situation, you can either spray them on or roll them on. In most cases, they dry relatively quickly and are easy enough for anyone to apply. The only downside to these coatings is that it can be difficult to get an even level of coverage across your entire roof. To prevent any problems, be sure to read the directions from the manufacturer before applying the membrane to your roof. A lot of people tend to use these on log cabin kits such as those from logcabinkits.co.uk.
If you prefer, you can also use a rubber membrane that comes in the form of a large sheet. The primary benefit of sheet membranes is that the thickness of the membrane is uniform across the entire surface of your roof. They are, however, more difficult to apply than liquid membranes. They also tend to cost more. They usually have a sticky coating on one side that helps them adhere to the roof. Trying to peel off the paper to expose the sticky substance can be tricky. If the surface comes in contact with your roof, it is hard to remove. That means that you need to have everything precisely in place before peeling off the backing to avoid having the membrane stick in the wrong places.
You also need to make sure that the sections of membrane overlap correctly on the roof to prevent water from leaking underneath them. The laps between sheets need to be wide enough to prevent leaks. You can learn more about how to properly install one of these membranes by reading the instructions provided by the manufacturer. In most cases, you also need to seal the joints using mastic or some other special type of sealer. Typically, working with these membranes is a multi-person job. If you need to nail the membrane down, there are many roofing nailers on the market that can help speed things up.
Sodium bentonite is a good environmentally friendly choice for waterproofing a roof. It can be used on either smooth or rough surfaces, making it a versatile choice. It also has excellent waterproofing properties. Because the clay used to make this product is biodegradable, it is also a more eco-friendly choice than some other waterproofing materials.
