 Spring maintenance for your roof

Now that the weather is getting warmer and sunnier, it’s a good time to go outside and take a hard look at your roof. Harsh winter weather can really take its toll. While you’re looking for roof damage, it is also important to look closely for another potential problem, moss and algae. You’ll want to pay especially close attention to the north-facing side if you have a pitched roof. If you see discoloration or green and grey patches on your roof, even if it is a tiny amount, it’s a sure sign your roof could need some maintenance.

Three major threats

There are three different threats when it comes to roof discoloration and each one poses its own problems. The first is pollutants from rainwater. It starts out as black streaks on your roof but can eventually make your entire roof look darker. This is the easiest of the three to deal with.

Algae, like pollutants, can be black colored as well but this threat is a living thing. It attaches itself to your roof strongly and then grows. The major problem it poses is that when it rains, the roof stays wet longer in that area and can lead to serious problems for your roof.

The third threat is moss which like algae is a living thing but it grows much thicker and can cause water damage to your roof if not taken care of promptly.

Eliminating algae and moss

While you could tackle this project yourself, it can be very risky. First of all algae and moss can be very slick and pose serious hazards for you as you try to remove them. Also many chemicals you might use can cause damage to your roof and any plant life that surrounds your home. A roof cleaning company is probably your safest bet for protecting your roof against pollutants, algae, and moss.
