What Should a Roof Look Like?

Whether you are a first-time homeowner or have lived in the same house for decades, you may wonder how to know if your roof is good or bad.  

This article will consider how to tell if your roof has serious problems and some things you should be on the lookout for.  

How Do I Know If My Roof Is in Good Working Order? 

If you are currently satisfied with the look of your roof and are not experiencing any abnormalities, you may not need to replace your roof. However, if your roof is experiencing any of the issues listed below, it is time to schedule a roof inspection and possible repair.  

Here are five issues that mean professional attention is needed immediately.  

Curling Shingles  

Roof shingles are flat, rectangular pieces of asphalt, composite, or other roofing material that are applied from the base of the roof in an upward direction. They overlap on the roof to provide full coverage.  

As your roof ages, the shingles will naturally begin to loosen. When this happens, homeowners may observe some curling and debris. This could be a result of shingles in poor condition. The shingles may need to be replaced.  

Granule Loss  

Granules are the sand-like exterior coating of a shingle. If you notice granules on the ground or in your gutters, your roof may be experiencing granule loss. Granule loss occurs when granules are dislodged and swept away by run-off.  

Granule loss is unavoidable and happens with most roofs over time. However, this problem signifies that the roofing system is nearing its end-of-life and should be tended to. Shingles without granules provide less protection. 


Streaking on the roof is not only unattractive, but it may also signify a serious roofing condition. Dark streaks may occur due to the accumulation of dirt, mold, or Gloeocapsa magma.  

Gloeocapsa magma is a blue-green algae that builds up over time. Although this will not create any long-term damage, it is unsightly and should be taken care of.  

Roof is Older than 20 Years 

A high-quality roof generally lasts between 20 to 100 years. As a roof ages, changes will occur, which may affect the homeowner’s insurance.  

The older the roof, the more scrutiny insurance inspectors will give. Moreover, as a roof gets older, insurance rates are likely to increase, but coverage will likely decrease. As a result, we recommend that roofs between 10 -20 years get regular inspections.  


Moss is a fuzzy green substance that grows on roofs. It’s a nonvascular flowerless plant that absorbs water.  

Although a limited amount of moss should not cause too much damage, a sizeable amount of moss can degrade the structure of your roof. Therefore, it’s recommended that professionals look at your roof for possible solutions.
