Is PU Sealant Effective Against Roof Leaks?
Polyurethane sealant is a highly effective, water-resistant adhesive that can be applied to most surfaces. When used on a roof, it can help to prevent leaks, as well as protect against mold and mildew. This type of sealant should not be confused with polyurethane foam insulation, which is often used to insulate attics and walls.
Unlike other types of roofing materials, such as asphalt shingles or clay tiles, roofs do not last forever. They are prone to wear and tear over time that can result in water damage to your home’s interior. Roofs can also be damaged by high winds or rain. If you've noticed that your roof has begun to leak lately, then it may be time to consider repairing.
What is PU adhesive sealant made of?
The polyurethane sealant is made from two parts: a polymer and a catalyst. The polymer is the part that bonds to the surface, while the catalyst allows it to cure. A PU sealant can last for up to 10 years, depending on how much traffic it gets and whether or not it’s exposed to extreme weather conditions such as heat or cold.
What are the benefits of using Polyurethane Sealant?
Polyurethane sealants are one of the most commonly used materials for roofing purposes because they are extremely effective at preventing leaks. Here are some of the biggest advantages that polyurethane sealants have to offer:
- Easy to apply
The sealant can be easily applied by using a simple caulking gun or trowel. You'll want to make sure that you follow all instructions included with your product to ensure proper application and results.
However, even if you don’t know how to apply polyurethane sealant correctly, it's still easy enough for anyone to do so without any prior experience.
- Watertight and leakproof
Polyurethane sealants create a watertight seal that prevents moisture from entering your home through roof leaks and cracks caused by shifting temperatures or weather conditions. This protects your home from water damage caused by leakage as well as mould growth.
- More durable than other types of sealant
The durability of a sealant is very important because it determines how long it will last before needing to be replaced. The longer an asphalt roofing system lasts, the more cost-effective it is. Polyurethane sealants can last up to 15 years or more when they are properly applied and maintained.
- Cost savings
Roofing tar costs significantly more than polyurethane sealant— sometimes as much more per gallon. You can save hundreds or even thousands of dollars by choosing polyurethane over roofing tar for any repair job.
