If you’ve been too busy to pay close attention to your roof, don’t be surprised to find it filled with all sorts of stuff that shouldn’t be there in the first place. You know that your roof is in dire need of cleaning when piles of leaves, twigs, and other kinds of organic debris begin to block the gutters and trap rainwater on your roof. Other signs that your roofing system needs a little TLC is when moss or algae grows on it or when ugly black streaks caused by the growth of blue-green algae start to show on your roof’s surface or when the overall look of your roof turns dull.

We also published the definitive guide on removing roof stains which you can read. Unless you want to start saving up for an impending roof replacement project, stop ignoring your roof. The water that’s retained on the roof due to the accumulation of organic debris that’s blocking the gutters will eventually cause your roofing material to rot. When the integrity of your roofing system becomes compromised because of damaged shingles, this could spell disaster in the event of a heavy rainstorm. Furthermore, if you live in a region where the weather is mostly wet and cold, you can expect moss to grow quickly on your roof. When moss creeps into your roofing system, its uncanny ability to increase wear and tear will ultimately shorten the lifespan of your roof. If you fail to do something to fix this moss issue, moss growth will cause water to get trapped on your roof’s surface until the sealing on its shingles begin to weaken and they become dislodged. Furthermore, failing to deal with the black streaks of algae on the surface of your roofing system will ultimately penetrate your roof deck when considerable damage to the shingles and wood is left unattended. Even if your roofing system doesn’t have moss growing on it or isn’t riddled with zebra stripes of blue-green algae, a dirty and dull-looking roof won’t only make your home look old, ugly, and uninviting, but it will also significantly diminish its curb appeal.
