No roof is immune from UV ray damage, and no roof coating prevents UV ray damage. Metal roofs are UV ray-resistant, especially with proper coatings. But even then, these rays eventually degrade the coating and damage the tiles. In many cases, UV ray chemical damage accelerates this process. This radiation breaks down asphalt molecules, so they lose their protective properties. Shingles that no longer effectively resist water absorption or block out UV rays age and deteriorate prematurely. Spotting UV roof damage is one of the hallmarks of a good roofing company in Phoenix, AZ, like Four Peaks Roofing.
Ground-level inspections often allow homeowners to spot some signs of roof damage. But subtle UV damage requires closer inspections. DIY on-roof inspections are time-consuming and risky. Let a Phoenix, AZ, roofing company assume that risk and know that a professional roof inspector, not a roof inspector/salesperson, is doing a thorough job.
A Roofing Company in Phoenix, AZ, Talks About Warning Signs
Seemingly insignificant UV ray skin damage quickly becomes melanoma or another serious health condition that’s expensive and difficult to treat. The same principle applies to UV-ray roof damage. People can avoid UV skin damage by staying out of the sun. However, a roof cannot stay out of the sun. So, a professional inspector must look for some physical signs of damage.
Fading and Discoloration
One of the most obvious signs of sun damage is the fading and discoloration of roofing materials. Asphalt shingles, tiles, and other materials can lose their vibrant color due to prolonged exposure to UV rays. Fading affects a home’s aesthetic appeal and indicates that the shingles’ protective granules are wearing away.
These protective granules often stand between roof tiles and severe sun damage. This thin line underscores the need for protective UV coatings, which are basically roof sunscreen. More on that below.
Tile Splitting or Cracking
Phoenix, especially the rapidly growing outlying suburbs, is widely known for its sunny days and dark nights. These extremes are aesthetically pleasing but dangerous to surfaces like concrete walkways and tile roofs. Constant expansion and contraction cause splitting and cracking.
Once moisture gets past the roof’s protective barrier, it causes a wide range of issues inside a home, not the least of which is black mold, which transforms a house into a toxic waste dump.
Curled Shingles
Curled shingles are a more advanced problem than cracked shingles. Tiles usually curl when they are nearing the end of their usable lives. Typically, these homeowners should consider pre-planned roof replacement. This alternative, while costly in many ways, is much cheaper than an emergency roof replacement. Due to the heat, shingles may start to curl or buckle, compromising their ability to protect your home from the elements. Curling shingles are often a sign that they are nearing the end of their lifespan and must be replaced. Ignoring this issue can lead to more significant problems, such as water infiltration and structural damage.
Blistering
Trapped moisture or excessive heat causes blisters to form on shingles. Like blisters on feet, when roof blisters pop, the result is further roof damage and the creation of weak spots in a roofing system. Blistering is a sign of extreme roof stress from the sun. This problem requires immediate attention to prevent leaks and other issues.
Granule Loss
We touched on this issue above. Asphalt shingles are coated with granules that protect them from the sun’s UV rays. Over time, these granules can wear off, leaving the shingles exposed and more susceptible to damage. Initial granule loss is very common near gutters or around a home’s perimeter.
Most people don’t know what a roof granule looks like, let alone how many granules are needed to protect the tiles. A professional inspection is required. If that professional doesn’t mention granule loss in the aforementioned areas, the inspector may not be much of a professional.
How a Roofing Company in Phoenix, AZ, Protects Your Roof
As is the case in so many other areas, roofing contractors and homeowners are partners that work together to prevent or repair UV roof damage.
UV-Resistant Coatings
Roof sunscreen isn’t a panacea. But UV damage is so extreme that every bit of protection helps. Coatings reflect sunlight and reduce the heat absorbed by roofing materials, prolonging their lifespan. Like frequent inspections, UV-resistant coatings are an excellent investment for protecting your roof from the harsh summer sun.
Proper Ventilation with a Roofing Company in Phoenix, AZ
We offer several alternatives to ensure proper ventilation in the attic to prevent heat buildup. Adequate ventilation helps regulate attic temperature, reducing the strain on roofing materials. Proper ventilation also improves energy efficiency simply by keeping attics cooler.
Shade Solutions
Planting trees and deploying awnings are the next best things to staying out of the sun. Any shade also reduces a roof’s surface temperature, which is usually almost twice as high as the air temperature. However, be mindful of placement issues. Branches and tree debris can fall and damage the roof, and improperly mounted awnings strain the tiles.
Regular Inspections
Diligent homeowners should schedule regular roof inspections, especially during the summer months. A professional roofer identifies signs of sun damage early and recommends any necessary repairs. Inspections catch issues before they become major problems, saving homeowners time and money in the long run.
Regular Maintenance with a Roofing Company in Phoenix, AZ
