Sealants are almost mandatory for flat roofs, but can also help sloped roofs. Sealants, when applied to sloped roofs will help in the prevention of leaks and also act to extend the life of the roof. Roof sealants can make a roof look more attractive and boost curb appeal. In some cases, they can also act to increase the energy efficiency of a home by reflecting the light and heat that falls on it.

The cost of roof sealants and their application will depend on the quality of the sealant, with those that can reflect light costing more than the others. Costs of application on pitched or sloping roofs are more because of the extra care that working on such roofs requires. Costs can also depend on the condition of the roof before the application of a sealant, as roofs need to be cleaned before any application of roof sealant is made on them. Sealants will also not stick to roofs that are dirty and where they are applied on roofs with dirt, these sealants will peel away after some time.

With this Roof Sealant product, it is specifically engineered to do exactly what the name implies- seal roofs and prevent roof leaks

Details and Features :

Let us look at some of the Roof coating, Sealants best features:

  • Very economical
  • No rinsing required before applications
  • Environmentally friendly
  • Can be applied to wet surfaces and exposed to rain or snow immediately

Roofs must be inspected for damage before any sealant is applied to them, and repairs made to all its defective elements before the sealant application. The coatings will extend the life of a roof, as they reduce the heat being transferred into the building and this decreases the expansion and contraction of the roofing membrane and thus prevent any thermal shock. They can go a long way in preventing leaks, and certain forms of sealants which are reflective can help a homeowner to save on energy costs.

You can apply a roof sealant on any type of roofing material, though roofs that are ballasted and have gravel-surfaced membranes may not be suitable for sealing. A reflective coating can contain aluminum, or be made with silicones, urethanes or acrylics. Most sealants will require primers and these primers can depend on the substrate and the type of coating. Ever sealant manufacturer will have his specifications for the primer and roof material and these must be used for better performance. Coatings of roof sealants can be sprayed or applied by brush or roller. Roofs need to be thoroughly cleaned and allowed to dry before any primer application is attempted.

Factors to consider when choosing a roof sealant

1.Tensile strength of the sealant

Tensile strength is the amount of force a material can withstand before it deforms or breaks. When selecting a roof sealant, there are two factors in its tensile strength you should consider, namely:

•Tensile strength after it just came out of its packaging
•Tensile strength after application

On the packaging of roof sealants, there is information concerning the tensile strength of the product. Most sealants only specify the tensile strength before use, but to be on the safe side, you should choose a product that defines tensile strength after application. The best products are those with the highest tensile strength.

2.Permeability factor

Lower permeability indicates a higher resistance to allowing humidity to seep through the material.

3.Percentage of moisture gain by weight

Some roof sealants tend to absorb water instead of repelling it. An absorbent roof sealant can cause deterioration of your roof due to damage from moisture. You should choose a roof sealant that repels water to avoid any problems relating to humidity.

4.Peel adhesion of the sealant

Peel adhesion is the ability of a sealant to stick on the applied area, even in adverse circumstances. This is one of the essential factors to consider because a sealant that doesn't stick to its applied area cannot be able to safeguard your roof adequately.

5.Reflectivity

A reflective roof sealant protects from UV damage and also serves to cool your roof. This reduces the need for constant maintenance and decreases your electric bill because the interior of your house gets heated up slower on a sunny day.
