A single fallen tree limb can cause enough structural damage to go through a roof. While this may not cause structural issues, it’ll still damage your roofing material and components. So, it’s a good idea to call a roofer to assess the situation even if a fallen tree or tree limb didn’t go through your roof. Another way a tree can cause damage is, over time, the constant rubbing between the limb and asphalt shingles damages them beyond repair. A third way a tree can damage your roof is when fallen leaves, sticks, seedlings, etc., are allowed to sit on your roof. While sitting debris anywhere on your roof is a problem, the main concern is in your roof valleys. A literal dam is created with the debris that doesn’t allow water to flow down your roof properly. This causes water to back up before eventually finding the path of least resistance, which leads to leaks. There's also the issue of debris becoming saturated and sitting in the valley.
The longer the saturated debris is allowed to sit, the more damage it does.
