Dark spots on your roof are typically caused by algae. The streaks from on the northern slopes of roofs where it might be darker and also wetter which is an ideal space for algae to grow.

Algae growth is not harmful but it might affect the overall appearance of your home and even the resale value of your home if you choose to sell it.
The southern slope of a roof will typically wear faster than the other slopes because it receives more sun exposure. UV rays will break down the roofing material over time but this will happen slowly.
Many times, the cause of water dripping between the roof shingles and gutter system is because there was no drip edge installed. The drip edge is a metal flashing that should be installed under the first row of shingles on the roof slope. Having a drip edge installed to your roofing system is important and will help prevent other roofing issues in the future.
