How Rain Affects Different Roof Types


March 4, 2025


Rain can be both a blessing and a challenge, especially when it comes to your roof. The type of roof over your head plays a major role in how well it handles wet weather. Some roofing materials are resilient, while others may need a little extra TLC. Our JM Roofing team has a quick breakdown of how rain impacts different roof types and how you can keep them in top shape.

Asphalt Shingles

One of the most common roofing materials, asphalt shingles, is relatively durable against rain. However, prolonged exposure to moisture can lead to weakening over time. Water can seep through cracks or missing shingles, allowing leaks to develop. To stay ahead of the problem, check your roof regularly for any damaged or loose shingles. A little routine maintenance, like sealing small cracks, can go a long way in preventing emergency water damage.

Metal Roofs

Metal roofs are known for their excellent water resistance. Their smooth surface lets rainwater run off quickly, which minimizes water-related damage. However, poor installation can sometimes lead to leaks, especially around seams and fasteners. Additionally, rust can form if the protective coating wears off, reducing the roof’s lifespan. To ensure your metal roof performs well, inspect it for signs of rust and check seams annually to avoid surprises.

Tile Roofs

Roofing made from clay or concrete tiles can easily handle heavy rainfall. These materials are extremely durable, but there’s a catch—tiles can crack under physical stress, like a falling branch, allowing water to sneak in. Water buildup under the tiles may also lead to mold or rot in the underlayment. To care for a tile roof, replace broken tiles promptly and ensure proper drainage to avoid standing water.

Flat Roofs

While flat roofs may sound modern and sleek, they’re a bit more vulnerable to rain. Their slight slope makes it harder for water to drain off quickly, leading to pooling. Over time, this standing water can cause leaks or even structural damage. To protect your flat roof, clear out any debris and make sure your drainage system is functioning. Regular waterproofing treatments can also help extend its life.
