Your office roof protects your business and employees from the whims of the weather. But just like any other structure, commercial roofing will suffer damage from harsh conditions over time. While some issues are readily apparent, others are easily overlooked. Here are five to watch out for.

Indications You Need Commercial Roof Repair

1. Algae

Dark, black stains point to algae growth, which forms because of dirt and mildew buildup or because spores have blown onto your building. While algae does not cause structural damage, it is unattractive. Commercial roofing contractors have access to fungicide products that can help stave off further growth.

2. Water Spots

Water rings or spots on the ceiling or walls often indicate a roof leak, especially after a storm. And while, logically, you would think that the hole would lie just above the drip, it's possible that the water has traveled from elsewhere on your roof and pooled at a low point. 

3. Mold

When there is moisture present on your roof, it can stream through gaps and cracks, leading to internal mold growth. While sometimes confused for algae, mold is often worse, since it can pose a hazard to one's health. Call a commercial roofing contractor to repair the source of the leak and then a mold expert to remove the spores.

4. Leaks During Temperature Changes

Some roof leaks may only be noticeable during the winter. Backed-up water that pools on your roof will freeze when the weather gets too frosty. Repeated freezing and thawing cause the ice to build and creates a barrier that stops precipitation from draining off. Water needs somewhere to go, and in these situations, it will often find its way inside. Check the insulation under the roof and make sure your building is adequately ventilated to prevent these so-called "ice dams."

5. Rusty Gutters

Water on metal leads to rust. If your gutters have a rusty buildup, moisture may be seeping out between seams or cracks, rather than being directed away from the building as intended. This could lead to several problems, including foundational issues. Therefore, clean out your gutter system regularly and if that doesn't resolve the issue, consult a professional about a new system.
