Roof stains can be unsightly. You might even notice them before a roofer points them out. But are they really a big deal? Roof stains might be difficult to spot at first, but there are good reasons to take care of them. Here's what you need to know about roof stains.

The Cause of the Stains Impacts Your Next Steps

Roof stains are usually caused by algae or lichen. These growths thrive in moist, shady areas. If your roof has moss or liverworts, it's likely that the stains are being caused by one of these growths. Algae and lichen can cause your shingles to deteriorate. The longer the growth is left unchecked, the more damage it can do. In extreme cases, it can even cause your roof to leak.

Cleaning Stains Can Prevent Future Problems

Cleaning roof stains is important, even if the stains don't pose an immediate threat to your roof. Algae and lichen can spread quickly, so it's important to nip the problem in the bud. Cleaning roof stains is also a good way to extend the life of your roof. Regular cleaning can help prevent the growth of some materials.

The process of cleaning roof stains includes inspecting the roof for affected areas before power washing the roofing material. This will be done with water and a cleaning solution. After the roof has been power washed, a sealant can be applied to help prevent future growth.

It's important to hire a professional roofing contractor to clean your roof stains. They will have the experience and equipment necessary to do the job safely and effectively.

Some Stains Require Total Replacement

In some cases, the parts of your roof that are stained will need to be replaced. This is usually the case with shingles that are severely discolored or deteriorating. For example, if you have a tile roof, some of the tiles might need to be replaced. This is usually only necessary if the tiles are cracked or broken.

Stains Aren't Always a Bad Thing

While roof stains can be unsightly, they're not always a bad thing beyond the fact that they might not be pretty. Some stains are benign. If the stains are caused by dirt or soot, they probably won't cause any damage to your roof. These stains can usually be cleaned.

Call a Roofer to Check Out the Stains

If you're not sure what's causing the stains, it's best to call a roofer. A professional roofing company will be able to tell you what's causing the stains and recommend the best course of action.
