Understanding the Natural Aging Process of Asphalt Shingles

Asphalt shingles happen to be used on about four out of five homes in the United States, which does make them the leading choice in residential roofing which is not surprising with all of their advantages. Asphalt Shingles come in a wide range of colors, textures and are the most affordable.

Most shingle manufactures offer a full line of asphalt shingles, which include 3-tab as well as architectural. Each type of shingle will undergo a natural aging process.

Recognizing the Signs of Asphalt Shingle Aging:

It is natural for your roof to age and the aging process begins as soon as your roof is exposed to nature. The sun can raise rooftop temperatures as high as 60-70 degrees above the ambient temperature. Excessive heat and ultraviolet radiation from the sun can accelerate the aging of your shingles. Other things such as weather, walking on your roof and heavy snow can also contribute to your roof aging. Asphalt Shingles begin to age as soon as they are installed on your roof. Cracking, blisters, granule loss, buckling, curling and algae staining are all signs of aging.

Shingle Curling

Curling is common in some shingles and is not a defect. It is natural for your asphalt to age and the layers to shrink with time. The shrinkage is what causes the edges of the shingles to curl.

Shingle Cracking

Minor shingle cracking may not be noticeable from the ground however you might spot them while hanging your Christmas lights. Hight heat from the sun often causes the protective oils in the shingles to deplete which will cause minor cracking. This is all normal weathering and is not cause for panic as long as your shingles are still shedding water. Severe cracks that penetrate through the roof should be repaired and or replaced.

Shingle Blisters

Occasionally, naturally occurring small, circular raised areas which are known as blisters may appear on your roof. These can vary in size and may be open or closed. They most often occur due to the attic being under ventilated. Closed blisters are not a reason for concern as long as your shingles are still shedding water. In the event that these blisters are open you should have a roofing professional assess your roof condition right away to have the shingles repaired and or replaced.

Algae Staining

In moist or humid areas, you may notice dark brown or black patches that appear on your roof. These streaks result in a dirty roof and are usually more visible on lighter colored shingles. This is a natural occurrence, and the stain is caused by algae growth which does not affect the ability for your shingles to shed water. Algae should not be confused with moss or tree droppings which usually only cause localized discoloration.

Granule Loss

Granules are used in the shingle manufacturing process, so some granule loss is common when your roof is first installed. There are some other factors which can cause more extensive granule loss such as foot traffic on your roof, hail, tree limbs, and weather. In the event that you notice that there is exposed asphalt on your roof due to granule loss you should have a professional roofer assess your roofing system right away to have the shingles repaired and or replaced.

Shingle Buckling

Shingle buckling is not technically a sign of roof aging but can occur months after installation. This can be caused from inadequate attic ventilation which tends to increase the moisture in the roof deck. Expansion and movement of the wood roof deck can lead to the shingles becoming buckled.

Got a recommendation to go with MCR, we didn’t know our home came without a ridge cap installed, til the rain started coming into the house. These guys were so quick the estimates, returning phone calls and getting the work done. We got a ridge vent and cap replacement. Didn’t need to spend more than what just needed repaired. Will be recommending them to everyone. Will be back in the future for more work. Thank you!

The entire team at Middle Creek Roofing was phenomenal. They replaced our roof in Lancaster, PA and we could not be more satisfied with the result. Janine made sure we were updated every step of way so we knew exactly what to expect and when to expect it. When the Crew arrived on install day they knew all the details of the project. They were kind, courteous of our surroundings, and very tidy while working. The clean up was flawless. 10/10 I would recommend Middle Creek Roofing for your next roof replacement!

House located in Bernville. Received a shingle replacement. They did a great job! They were super professional, very respectful of the property, cleaned up everything afterwards, and I can’t believe how fast they were. The flashing around the chimney and windows looks excellent, and the shingles are lying down the way they’re supposed to! Matt Tilley was our very professional and personable contact person. He got up on the roof and took videos of everything so we could really see what the issues were, and then he explained the whole roofing process really well to us. He also provided a follow up video so that we could see what the finished product looked like from up on the roof, which was really gratifying and helpful. We are very happy with this company and our new roof!
