Although your roof is one of the most intensely important parts of your house, it can be very easy to neglect it.  As long as there aren't any overtly obvious holes or leaks, you may think that your roof is fine.  However, even when there aren't glaring problems with your roof, it still may be time to replace it.  Use this information to learn more about the more covert signs that it's time to have your roof replaced.

Moss Or Algae Is Starting To Grow On Your Roof

If you notice moss or algae starting to grow on your roof, you may not pay it too much attention.  You may think that it's purely cosmetic, but it could lead to serious problems if it's allowed to grow unchecked.

Algae and moss will hold moisture onto the roof longer than it would ordinarily be there.  When rains come, some of the water that would normally slide off of the roof and into the rain gutters will be absorbed by the algae and moss.  This excess moisture can be quite harmful to the shingles of your roof, causing them to wear down and deteriorate prematurely.

The best thing to do when you have algae or moss growing on your roof is call in a professional roof cleaner.  They will have the materials, knowledge and expertise to know how to remove the growth without damaging your shingles.

You Have Poor Energy Efficiency

Another sign that it may be time to replace your roof is when you have poor energy efficiency.  If your energy expenses are significantly more expensive than those around you, it's time to consider whether or not your roof is the culprit.

If your roof isn't sound enough to block out a significant portion of the heat that bears down upon it from the sun, the excess heat will radiate into your home.  As a result, your air conditioning system could go into overdrive in attempts to maintain the temperature on your thermostat.  

You can use a website such as this one to find out what the average energy expenses are in your area.  If yours seem disproportionately high, call in a roofing contractor to have your roof inspected and possibly replaced.

Knowing when to replace your roof is the key to saving yourself from a major problem.  If you notice any one of these signs, contact a roofing contractor soon to put a plan in place.
