Flat roofs require extra measures since water does not naturally drain off of them after rainfall. Plus, you can’t just slap some paint on and call it a day; you need to use the right materials, techniques, and products. Waterproofing your roof will extend its life significantly, lowering the chances of requiring a roof repair in the future. Below, we’ve compiled the best methods for waterproofing your flat roof.
TPO Roofing Membrane
Thermoplastic polyolefin (TPO) roof membranes are an energy-efficient, cost-effective way to waterproof your flat roof. The membrane is waterproof and durable, perfect for drying your flat roof. Plus, the material is lightweight and easy to install.
We use either cold adhesive or self-adhesive methods when applying a TPO membrane. The cold adhesive method requires an even temperature throughout the application process. Otherwise, it’ll be like trying to stick a wet balloon to your roof. Self-adhesive is much more forgiving regarding environmental requirements and requires less time.
PVC Roofing Membrane
Polyvinyl chloride (PVC) roofing membranes are popular for flat roofs. The strong and durable material makes it perfect for keeping your roof dry. PVC membranes are also easy to install and come in various colors to get the look you want. It’s worth noting that PVC membranes are more expensive than TPO, but it may be worth it for some homeowners.
We use a compatible adhesive when installing the PVC membrane for an effective waterproof seal. Depending on the situation, we use either solvent- or water-based adhesives.
EPDM Roofing Membrane
Ethylene propylene diene monomer (EPDM) roofing membranes are another great option for flat roofs. The material is lightweight and durable, but it’s also cost-effective and resistant to damage from the sun’s UV rays. The membrane is also easy to install, so we can get your roof waterproofed in no time.
The membrane must be properly attached with adhesive or tape to ensure a tight seal for effective waterproofing. It’s also best to add a layer of protection using liquid waterproofing or coating materials.
Reinforced Bitumen Membranes (RBM)
For a more permanent and reliable waterproofing solution, you may want to consider using reinforced bitumen membranes. While this type of installation isn’t as cost-effective as EPDM, it’s still a good option for flat roofs and offers superior protection against moisture. The membrane should be applied to the roof using a combination of hot or cold adhesive and torching. It may also need a protective layer of waterproof sealant or coating.
Since bitumen membranes don’t come with self-adhesive backing, getting professional help to install and ensure all joints are properly sealed against the elements is crucial.
Liquid Waterproofing
For a quick and easy way to waterproof your flat roof, you might want to consider a liquid waterproofing membrane. This relatively new technology uses a two-step process to create an impenetrable barrier against moisture. The first step involves applying a primer coat, and the second is applying a waterproof sealer. Liquid waterproofing membranes are generally easy to install and offer superior protection against water.
In most cases, liquid waterproofing membranes will last up to 20 years and can be applied directly over existing roofing material.
Single Ply Membranes
If you’re looking for a cost-effective and durable waterproofing option, you may want to consider single-ply membranes. Single-ply membranes are made of a synthetic rubber material that is durable and resistant to UV rays, wind, and hail. They can be installed quickly, easily, and affordably. Plus, they are virtually maintenance-free, so you won’t have to worry about constantly checking up on them.
You will need to hire a professional to install your single-ply membrane. We will measure the roof and then cut the membrane so that it fits snugly on the roof. We will then use either pouring and rolling or torching to secure the membrane.
Rubber Membranes
Rubber membranes are your best bet if you want a waterproof material that rolls out the protection. Not only are they great for flat roofs, but they’re also perfect for slippery surfaces like stairs and walkways.
For an extra layer of protection, look into applying a waterproof sealant or coating over the membrane. This will help keep your flat roof in tip-top shape for years!
