While people appreciate that every thing grows old and will become different in the process and even though you may not see it as you enter your home every day, the changes are there for anyone who is keen to notice. The extremities of the weather and different climatic conditions will affect even the newest roof and, as such, a homeowner who knows what is taking place will not be caught unawares. While you may not find anything to rub on your roof in order to slow down its aging process, a simple periodic examination is one of the best ways to protect your roof and know when it is time to take any action.

The roof of your house is daily exposed to extreme weather conditions year in year out; scorching high temperatures during summer with baking rays and the effect of ultra violet rays that quickly degrades the granules on the shingles. There will also be other elements such as air pollution, moisture, snow, ice and hail as well as branches falling from trees. What all these conditions do is cause the contraction of the roof deck when it’s cold and expansion when it gets hot. This contraction and expansion that happens annually will begin to cause a strain on the shingles and enhance the aging process. 

Leaving those climatic conditions aside, there are other internal issues that will also cause trouble to your roof. These include issues to do with poor ventilation that can cause an increase of moisture leading to deck movement and damage which in effect affects the shingles on the roof. You should realize by now that there is really nothing you can do about the prevailing weather conditions and how they affect the roof of your house, a process that starts immediately you install a new roof.  

The following are signs that show your roof is aging naturally:

Curling: When asphalt hardens naturally the embedded granules will begin to break away and can be found even in the gutters. The asphalt layers will start to shrink as the hardening progresses while being countered by the reinforcements found in the shingles. This is a gradual process that you may not notice taking place but it will be going on anyway.

Cracking: Surface cracking for asphalt is also a normal part of the natural aging process as the oils used in making it begin drying out as a result of exposure to heat. This causes the shingles to become brittle and when it combines with the movement of the deck, some cracks are likely to appear on the surface.

Blisters: The shingles on your roof have a minimum ventilation requirement that needs to be met and when it is not met, blisters will appear on their surface; when this bubbling takes place the asphalt becomes exposed.  

Staining: You must have seen some dark colored streaks on the sides of some houses that are made with shingles with a lighter color. Most people will mistake this for things such as soot, debris from trees, moss or dirt. This change of color is almost always caused by the growth of algae and may be as a result of moisture retention.
