Most homeowners realize it is more cost effective to provide maintain their home when compared to paying to repair or replace things. One part of a house that will require maintenance as well as protection is the roof. The hot weather of summer can cause a roof to become damaged. This could cause leaks and failures in many places on a rooftop.
1- Infrared Radiation (IR) Damage
This type of radiation from the sun can cause a roof to experience damage. During the hot summer months, radiation from the sun can make the surface of a roof increase to temperatures that are over 150 degrees Fahrenheit. In some areas, the temperature will then go down to 90 degrees Fahrenheit during the night. This amount of temperature change will impact a roof. It causes a roof to expand and contract significantly daily. This can result in a roof’s fasteners and flashings failing. In many cases, they can’t handle the extreme expansion and contraction and may pop off.
2- Ultraviolet Light (UV)
When a roof is exposed to significant amounts of UV light from the sun, it will dry out the roof’s surface. This will cause cracks to develop. It can also cause a pattern of cracks to occur similar to an alligator’s hide. This is called alligatoring. Roofs with the highest risk in the sun are asphalt roofs. The sun’s light will oxidize the oils contained in the asphalt shingles. This will cause them to become brittle, and the thickness of the roof’s membrane will decrease significantly. When these materials break-down, it can result in a failure across the entire structure of the roof.
When a roof is exposed to intense heat for many years, the shingles can begin to decay. This is a real concern for older roofs. The shingles will appear rotted and deformed. There could be chunks of the shingles missing. If this isn’t corrected, it could cause a home to experience structural damage and more.
Intense heat over an extended period of time can cause the shingles on a roof to curl or bend upwards. This can happen with older shingles. It is a situation that will only get worse with continued exposure to the heat of the sun.
5- Roof Coating
One important way to protect a roof from being harmed by the sun is with a roof coating. When the right type of coating is used, it will be able to protect a roof from harmful UV and IR damage. Once a roof coating is applied, it may not need to be done again for up to ten years. A Cool Roof system involves a highly reflective roof coating being applied directly onto a roof. It will cover and protect the entire roof from sun damage. A roof coating is designed to significantly reflect more heat from the sun and absorb less of it.
6- Upgrade To A Green Roof
This is a very popular way to have a roof that can handle the heat of the summer. Many homeowners have experienced the benefits of upgrading their roofing with material designed to be Eco-friendly. This material is some of the most durable types of roofing material available. With proper maintenance, it is possible for it to last as long as 50 years and more.
7- Install A Vapor Barrier
In the summer it will rain. When the sun comes out, moisture could be trapped in a roof and the heat can cause problems. A vapor barrier is a way to prevent these types of problems from occurring. It is a sheet of material installed to prevent condensation from forming on a roof. It is possible to install this and have it prevent all moisture from passing through a roof. This is known as a vapor diffusion retarder.
8- Regular Roof Inspections
When homeowners invest in regular professional roof inspections, they can avoid having small problems become larger ones. This is an effective way to detect any roof damage from the sun before it can become an expensive repair. Roof inspectors will be looking for faded shingles, missing shingles, shingles with visible cracks, shingles that are decaying as well as shingles that have curled edges and more.
Many homeowners don’t address the problems with their roof until it is too late. This makes it common for a roof to sustain damage during the summer months. It may then be too late for a cheap repair. Proper roof maintenance is important. Taking steps to minimize problems associated with the sun’s heat can make a big difference in the lifespan a roof.
