Roofing protects the residents of a home from the weather. At the same time, it gets exposed to the weather. Sometimes, such exposure causes the roofing materials to get damaged. The damage’s cause can change by the same token, the characteristics in any damaged area can differ from spot to spot.

Impact Damage

Such damage gets caused by hail or branches. A homeowner does not always see the damaged area, but he or she can look for clues. For example, there might be flashes of metal observed during the roof’s examination. Those flashes of metal would signal one of two things. The flashing could mean that one of the shingles got dented. Alternatively, it could mean that some of the roof’s protective sealer is missing.

Thermal shock

Shock-related damages result from a seasonal occurrence, namely something called temperature swings. The greater the extent of the variations, the chance that the roofing could experience shock damages grows in proportion. By the same token, the older the dwelling that gets exposed to the changing temperatures, the chance for cracking grows in proportion.
In younger buildings, the tar in the roof demonstrates the necessary amount of elasticity. It expands as it gets heated and shrinks when it gets cold. As a private residence ages, so does the tar in its roofing. That substance becomes hard; it is no longer elastic. When a shingle gets heated by the sun, it expands, but the tar that holds the shingles together cannot. Instead those drier tar-like substances crack. That sequence explains the reason for cracks in certain roofing shingles.

Freeze thaw damage

This is a different sort of seasonal occurrence; yet it produces the same effect as the thermal shock. Any water that manages to work its way into a small crack in the roofing will freeze at night. The frozen water expands and makes the crack bigger. The next day more water gets into that same crack.
That cycle gets repeated day and night for many days, maybe many weeks. The crack in the roofing gets bigger and bigger. It allows more a more water to leak through the roof. Some of the above damages have become a greater concern in certain areas of the country. For example, freezing and thawing takes place repeatedly in colder regions. In warmer regions, the sun’s hot rays hit roofing during the day. That gets followed by cooler night temperatures. Roofers In Sunnyvale work to secure and safeguard your roofs effectively.
Residents in windy regions have the most reason to worry about impact damages. The wind can blow branches on a rooftop. Depending on the speed of the wind and the size of the wind-carried branch, the force that hits the rooftop could be quite impact ful.
