How Weather Elements Cause Roofing Damage

You have probably heard that weather elements pose some of the worst threats to your house, but do you know how the damage occurs? Here are some of the specific ways in which weather elements can cause or accelerate your roof's damage:

High Temperatures

High temperatures will affect almost all aspects of the roof. Here are some of the ways in which heat can damage the roof:

  • It accelerates the deterioration of the roofing materials
  • It causes expansion of roofing materials; this can lead to various damages such as cracking of wood used in the roof's construction
  • It dries out roofing shingles, leaving them britle and susceptible to damage


Hailstones cause roof damage in two main ways. First, the impact of the stones on the roof can create small dents on the roofing material, dents that can hold water and eventually cause roof leaks. Secondly, the impact of the stones can dislodge the shingle granules, which exposes the shingles to sun damage since it is the granules that protect the shingles from sun damage.


Rainfall may not be as hard as hailstones, but it can also damage the roof. This is especially true if the roof has already suffered another form of damage or is old and failing. The rainwater may seep into the roof and cause rusting and rotting of the relevant materials, reducing its durability. Rainwater then penetrates through the roof may also soak the insulation and reduce its effectiveness.


Snow damage to the roof also occurs in two main ways. First, the accumulation of snow on the roof may subject your roof's structure to more weight than it was designed or constructed to handle. In sufficient amounts, this may even cause the roof to cave in. Secondly, the snow will melt and expose the roof to water damage just as rainwater does.


Wind is one weather element that can damage the entire roof at a go; for example, a strong enough wind can rip off the roof. Strong winds can also uproot shingles or damage gutters. Secondary wind damage may occur when the wind force break tree branches or uproot trees, and the damaged trees end up on your roof.

You may not be able to change or avoid the weather elements, but you can mitigate their effect on your roof. For example, you can make sure that any rain that falls on the roof promptly flows off it into the gutters and are drained away. Talk to a roofing contractor for more mitigative or corrective measures for weather-related damage on the roof.
