Roofing Adhesive For Flat Roofs

by | Apr 26, 2023 | Flat Roofing

Flat roofs are becoming increasingly popular in both residential and commercial buildings. They offer numerous benefits, such as providing additional outdoor space, improving energy efficiency, and being easier to maintain. However, a flat roof can be prone to leaks, and one of the most effective ways to prevent this is by using roof adhesive. In this blog post, we’ll discuss the different types of roof adhesives available for flat roofs.

Roofing Adhesives for Flat Roofs

A roof adhesive is a material used to bind two surfaces together, in this case, the flat roof material and the underlying substrate. The adhesive ensures that the roof is watertight and prevents water from penetrating through the roof. The application of roof adhesives for flat roofs involves placing them on the surface of the substrate before laying the roofing material on top.

When selecting a roof adhesive for your flat roof, it is important to consider the type of roofing material, the climate in your area, and the condition of the substrate. The adhesive should be compatible with both the roofing material and the substrate and should be able to withstand extreme weather conditions. Additionally, the adhesive should be able to expand and contract with changes in temperature without losing its adhesive properties.

Types of Roof Adhesives

There are several types of roof adhesives available for flat roofs. Each type has its own set of advantages and disadvantages. The following are the most common types of roof adhesives:

Asphalt Adhesive

Asphalt adhesive is the most commonly used adhesive for flat roofs. It is made from asphalt and solvents and is applied as a hot or cold liquid. Asphalt adhesive is suitable for use with asphalt-based roofing materials, such as built-up roofs, modified bitumen roofs, and asphalt shingles. It provides excellent adhesion, is easy to apply, and is relatively inexpensive. However, asphalt adhesive has a short lifespan and can become brittle over time, leading to cracking and leaks.

Polyurethane Adhesive

Polyurethane adhesive is a two-part adhesive that is mixed together before application. It is suitable for use with a wide range of flat roofing materials, including PVC, TPO, and EPDM. Polyurethane adhesive provides excellent adhesion, is waterproof, and can withstand extreme temperatures. It is also resistant to chemicals and UV rays. However, polyurethane adhesive is more expensive than asphalt adhesive, and it requires a clean and dry substrate for proper adhesion.

Silicone Adhesive

Silicone adhesive, applied in liquid form, functions as a one-part adhesive. It is suitable for use with a wide range of flat roofing materials, including PVC, TPO, and EPDM. Silicone adhesive provides excellent adhesion, is waterproof, and can withstand extreme temperatures. It is also resistant to chemicals and UV rays. Additionally, silicone adhesive has a long lifespan and is less likely to crack or become brittle over time. However, silicone adhesive is the most expensive type of roof adhesive and requires a clean and dry substrate for proper adhesion.

Solvent-Based Adhesive

Solvent-based adhesive is a type of adhesive that is applied as a liquid and dries to form a solid bond. It is suitable for use with a wide range of flat roofing materials, including PVC, TPO, and EPDM. Solvent-based adhesive provides excellent adhesion and is waterproof. It is also resistant to chemicals and UV rays. However, solvent-based adhesive is highly flammable and emits harmful fumes during application. It is also more expensive than asphalt adhesive.
