Roofs are constantly exposed to ultraviolet (UV) rays the moment installation is completed. Fortunately, many of today’s roofing systems feature UV protection as a standard feature. This feature is something you should factor in when planning your next roof replacement. But what happens to an unprotected roof when exposed to UV rays?
The Effects of UV Rays
UV rays are part of the invisible parts of sunlight, which also include infrared rays and X-rays. Prolonged exposure can cause damage to roofs in several ways:
- Accelerated Fading – UV rays have a bleaching effect, which causes fading on anything with pigments, including fibers, printed matter, and home components such as roofing and siding. This can have an aesthetic effect on certain roofing materials like slate and can cause fading on other kinds of roofing.
- Loose Granules – Asphalt shingles are built with three layers: the backing material, the asphalt layer and the granules. Granules are there for many reasons, including impact protection, pigmentation and protection against sunlight. However the substance that helps keep it on the shingle mats can deteriorate over time, which can result in loose granules.
- Premature Aging – Roofs that aren’t protected against UV rays tend to show signs of aging much earlier. Curling, cupping and cracks manifest early, which requires an appointment with a residential roofing contractor to check if the roof can still be repaired.
Mitigating the Effects of UV Rays
You can’t really protect the roof from UV rays. As a matter of fact, it’s the other way around. But that doesn’t mean your roof has to suffer its effects, which we discussed. When planning a roof replacement, make it a point to include UV protection as part of your selection criteria.
Certain roofing systems — like the GAF Lifetime Roofing System — have reflective features that help mitigate effects of UV rays. Metal roofing systems likewise offer UV protection, as well as resilience against surface degradation. In addition to reducing the effects of UV rays, it also helps improve your home’s energy efficiency by reflecting the heat from the sun, caused by infrared rays.
