Primer and Reflective Paint: Making Roofs Last Longer

There are roofs that do not come painted or coated, so homeowners can decide for themselves what kind of paint and which color they want to use.

It’s easy to paint a new roof; if it has been previously painted, however, some preparation is needed. Using a putty or rubber knife, one should scratch out all the old paint. Afterwards, use a piece of rough sandpaper and rub out all the remaining chucks until the roof surface is smooth and blank. It’s important to make sure that all of the old paint has been removed; otherwise, if the new coat is painted on, it might not stick to the roof surface as best as it should.

After the roof surface has been cleaned, one should apply a primer. A primer that’s oil-based is most recommended, but there are also other latex primer types that are suitable. Make sure that the latex primer one uses, however, is especially for metal and exterior surfaces. Most roofs made of galvanized steel should be painted with at least one coat of primer. This will help make the paint last longer and stick more strongly to the surface of the roof.

The paint is added last. Roofing Worcester MA experts prefer using paint that is also oil-based. It lasts longer than latex paint, and it is easier to apply. Latex paint, on the other hand, dries more quickly but it’s harder to apply because it clots easily. The best thing that latex paint is that it’s cheaper than oil-based paint. If one wants a more elegant and smoother looking paint job for the roof, it’s better to use latex.

There are also kinds of paint that give roofs a reflective coating. This protects the roof from the effects of weather like extreme heat and intense cold. The coating also keeps the heat in and the cold out during the winter season. According to Worcester roofing, reflective paints are good for roofs in areas that have high humidity. They are also advisable for those who want to experiment with solar power because they can trap up to 85 percent of the energy from sunlight that falls on the roof.

Finally, for roofing Worcester MA residents suggest using water-resistant paint. This helps strengthen roofs against leaks that can be caused by constant rain and other elements. For more information about roof painting, visit eHow.com.
