Different areas of the country present different types of problems for our homes and roofs. In California, there are unique problems that are especially relevant under the Californian Sky. Here are some of the most popular problems you will see happening to the roofs of California homes.

Sun’s Rays/Heat

  • Strong ultraviolet (UV) rays deteriorate asphalt shingles over time causing blistering or buckling. Once this happens, the waterproofing material underneath is exposed to the elements and if not detected, the rain will eventually come through, causing a leak or leaks.
  • The summer months in California can reach 90+ degrees
  • Color deterioration of the asphalt shingle or tile. It doesn’t matter what your roof is made out of, eventually the sun will strip the color out of it. Keeping the color in roof tiles looking fresh isn’t the only issue as it can be a sign that there are other issues. It is safe to say that if your roof is looking dull, it has been exposed to the elements to a point that there may be damage.
  • Extreme heat can cause what’s known as “nail pops.” This is when the roof materials expand and contracts and inside the attic, heat tries to escape, popping the nail upward. This can cause buckling of the shingle over time, as well as an opening for rain to enter.

Wind Issues

  • Santa Ana winds can be very detrimental when it comes to asphalt shingle roofs. Strong wind can get underneath shingles and blow them off the roof. If winds are extremely strong, damage can occur to new, secure roof shingles.
  • The nails holding the shingles may have loosened, which lessens the roof’s ability to remain watertight and its ability to resist high winds in the future.
  • Shingles normally have adhesive strips or sealants between each layer so that each shingle seals to the one underneath it. High winds can break this seal. Like loosened roofing nails, this makes the roof less wind and water-resistant.
  • “Wind-damaged” shingles are not always visible from the ground.

  • Foot traffic – Whenever anyone is on your roof, whether to fix the AC, tent for termites, or to install solar panels, there is a risk of damage.
  • Penetrations using nails or screws in the wrong place, installation, or removal of large equipment such as AC units or solar can damage the roof.
  • D.I.Y. or having a non-professional roofer perform work on your roof could increase the possibility of damaging your roof.

Water Damage

As well as heat and wind, water and humidity are the other culprits for roof damage. The water itself is not bad, but it is the extreme heat which is followed closely by high humidity in the winter that causes damage. Water and cool air can form dampness in the attic, which in turn can become mold. High humidity is also responsible for cracking tiles after they have been exposed to a hot summer.

The high heat of the summer can also cause flashing to melt and deteriorate on the roof. If this is left unchecked, when it starts to rain, the water will leak into the house. It is better to have your roof checked at the end of the summer to ensure that no damage has been caused.   

Damage from the heat and the sun can weaken your roof and cause some of the popular problems listed above. That is why they do require some care and attention. If you do notice any areas of concern, you should contact a professional roofer to assess and fix any problems. And don’t forget, a roofer can also provide that essential maintenance to keep your home in top shape.
