Your home is not just a place where memories are made; it is your sanctuary, your haven from the outside world. But what if we told you that lurking above your head, an often-neglected danger threatens to compromise the very essence of your haven? Yes, we’re talking about your roof—the unsung hero that shields you from the elements day in and day out. However, even the mightiest of roofs can succumb to the relentless forces of nature, leading to leakages, water damage, and a plethora of headaches.
That’s where roof waterproofing steps in, offering an unparalleled solution that fortifies your home against the fury of rain, storms, and the passage of time. Waterproofing is more than just a smart investment; it’s a shield of invincibility for your roof, providing you with the ultimate peace of mind, knowing that your home is safeguarded against water intrusion.
What Is Roof Waterproofing?
Roof waterproofing ensures your home is protected from moisture. It is done by applying a waterproof material that acts as a barrier to prevent leaks from rain and snow. Otherwise, the water leaks can cause mold and structural damage.
Roof waterproofing involves applying a protective layer to prevent water from penetrating the structure and causing damage. Inadequate waterproofing is the most common reason for leaks. Roof leaks can cause costly damage to your house. The water stains on the ceiling and walls are unsightly and challenging to remove.
The mold patches on your ceiling aren’t only an aesthetic issue, but the spores can also trigger allergies. Leaks create a humid environment that is the perfect breeding ground for mold and fungus. On the other hand, the moisture can cause severe structural damage. When the beams are continuously exposed to dampness, they will become weaker. Over time the beams may break down, and the roof can collapse in that area.
How Do You Waterproof a Roof?
Waterproofing roofing systems require suitable materials and expertise. The proper waterproofing materials get applied over the concrete to create a protective coating that prevents the water from penetrating the holes and dents. The edges of the protective coating get beveled. Also, professionals install an adequate drainage system to guide the water flow and prevent puddling. The waterproof layer is then finished with paint.
What Are the Most Common Roof Waterproofing Materials?
The quality of the waterproofing job depends on the materials used and how they are applied. Remember that waterproofing and coating a roof aren’t necessarily the same. The purpose of the coating is to protect the roof from UV rays, but it doesn’t provide water protection.
There is a wide variety of roof insulation materials available on the market. The final choice depends on the weather conditions in your specific area. Bitumen is the most commonly used material, known for its durability and affordable price. PVC and TPO are applied as single-ply material and come in a light color to repel the heat, which is ideal for hot climates.
Another thing to keep in mind is the installation process. Roof waterproofing must be applied appropriately by a professional to ensure efficiency. An improperly installed coating can let moisture seep through the cracks, resulting in higher costs for roof replacement.
Bitumen-Based Materials
Bitumen-based materials are easy to use and provide excellent value for the price. Thanks to these advantages, they are widely used in the construction industry. Bitumen is made of organic liquids and has a thick and sticky consistency. It can be applied in two ways: as a liquid and in semisolid form using a roll.
The bitumen waterproofing membranes get laid over the concrete roofing and sealed with a blowtorch. The bitumen adheres well to the roof and offers a protective layer that repels water. The bitumen roll comes in different thicknesses. It can also come with mineral stones on the upper surface as decorative details for the finish.
The liquid waterproofing membrane gets applied as a coating using a brush or a roller. This application method is ideal for perfectly flat roof surfaces, providing even application in every nook and cranny. Also, applying liquid bitumen is perfect for touch-ups and regular roof maintenance. The liquid doesn’t need to be sealed with a torch making it ideal for areas where open flame is restricted.
PVC Roofing Membrane
The PVC roof membrane is a single-ply membrane made of white polyvinyl chloride. The white color reflects the sun’s rays and prevents the surface from absorbing heat, which keeps the building cool. If installed properly by professionals, the PVC membrane can last for 25 years. It is a durable and affordable solution that is also fire-resistant. Plus, it is a low-maintenance option ideal for residential and commercial buildings. However, remember that dirt will be more visible on white.
TPO Protective Membrane
Thermoplastic polyolefin, or TPO, is another single-ply material to use if looking for a waterproofing membrane resistant to heat. The white color reflects the heat, which helps keep the temperature in the building comfortable. TPO is a cost-efficient option that is durable and easy to clean. The protective membrane will last more than 25 years with professional installation and proper care. The product might not keep its perfectly white appearance due to dirt, but this doesn’t affect its functionality.
EPDM Membrane Roof Coating
EPDM roof membrane is used in commercial and residential buildings. It is made of synthetic rubber highly resistant to weather elements. EPDM is available in black and white colors so that you can pick the right fit for your needs. The dark color absorbs heat, which cuts down on heating costs. The white surface repels heat, keeping the rooms cooler and reducing air conditioning costs. When installed by an expert, the EPDM roof membrane can last anywhere between 25 to 30 years.
What Is the Cheapest Way to Waterproof a Roof?
The total cost of waterproofing a roof depends on the material and size. The cheapest material for waterproofing a room is bitumen. The price for the material ranges between $0.85 to $1.50 per square foot. The total installation cost ranges between $1 to $2.50 per square foot. Bitumen is a highly durable material for any weather conditions that provides excellent value for the price, given it lasts more than 25 years with proper installation. Remember that covering a sloped roof takes longer and requires safety measures, so the cost would be higher.
