Decay - Aging roofs combined with extensive exposure to direct sunlight can cause the roof to decay. Naturally, roofing materials will deteriorate over time and the sunshine can speed this process up. UV rays can cause the roofing materials to weaken, crack, and dissipate. When this happens, the structure of your roof can be compromised and significant damage can happen.
Asphalt roofs will show signs of peeling, buckling, or eroding shingles leaving the surface below vulnerable to damage. Metal roofs are a little more difficult to spot signs of decay as the underside is where the corrosion typically occurs. This can happen if water gets under the metal panels and doesn’t escape. Similarly, tile roofs are difficult to spot signs of decay. The materials underneath the tiles are more likely to show signs of corrosion, especially if any tiles are missing allowing water inside.
Leaking - Roofing materials can quickly dry out with the excessive summer sunshine. Materials can become brittle and inflexible causing the roof to not hold up during high winds and rain storms. When faced with any force, the roofing structure is likely to crack and cause leaks. Not only will these cracks leave the home prone to water damage, but your air conditioning can also escape.
