Hailstorms can cause significant damage to roofs, depending on the size and intensity of the hailstones. Different roofing materials have varying levels of resistance to hail impact. Here is an overview of the impact of hail on different roofing materials:
1. Wood Shake or Shingle Roof:
Wood shake or shingle roofs can be vulnerable to hail damage. Regular maintenance and prompt repair of any hail damage are essential to prolonging the life of a wood shake or shingle roof .
2. Tile Roof:
Tile roofs can also be susceptible to hail damage. It is important to inspect and repair any damage caused by hail to ensure the longevity of the roof .
3. Metal Roof:
Metal roofs are generally more resistant to hail damage compared to other roofing materials. However, it is important to note that the UL 2218 Impact Resistance Test, which measures the impact resistance of roofing materials, is performed on new roofing materials only . Therefore, the impact resistance of a metal roof may decrease as it ages .
4. Asphalt Shingle Roof:
Asphalt shingle roofs can vary in their impact resistance depending on the type of shingles used. Some asphalt shingles are designed and manufactured to have higher levels of impact resistance, making them more resilient against hail damage .
5. Impact-Resistant Roofing Materials:
There are impact-resistant roofing materials available in the market that are specifically designed to withstand hail damage. These materials are tested and certified for their impact resistance according to standards such as UL Standard 2218. Roofing materials are rated from Class 1 to Class 4, with Class 4 being the highest possible rating .
It is important to note that the impact resistance of roofing materials is not the only factor to consider when choosing a roof. Other factors such as climate, cost, and aesthetics should also be taken into account.
