· If you are lucky enough to spot any dark, dirty-looking patches on the roof, then it is time to replace the roof, or at least replace the dirty shingled area. The cause of this can be environmental pollution, vegetation on the roof itself, algae or/and fungus growth and possible loss of granules because of the age of your shingles.
· When you see missing, cracked, or even curling of the shingles, this is a danger sign. The obvious causes of this will be the shingles have just reached their full lifetime on the roof.
· Many homeowners complain of leaking water in there attic space after a hard rain. This is because of inadequate shingle underlayment, and flashing that has too much wear and tear.
· Your roof shingles, your sheathing on the roof and siding decay are another sign of damage to the roof that most homeowners do not notice. Homeowners can resolve this problem by making sure that the attic is properly ventilated.
· When blistering and or peeling of the paint that is on the outside of your home happens, it is most likely the cause of any excessive moisture or high humidity also due to poor attic ventilation.
· Every homeowner at one point or another have probably experienced stains on their interior ceilings, walls, or even mold and also mildew growth. The causes of this problem can be yet again faulty or problematic shingle underlayment that is allowing leakage or not enough air flow.
· Finally, homeowners are often times plagued by very high excessive energy bills. This can become very expensive and the cause of this is not enough attic air flow which causes the heating and cooling system to run more than needed.
The typical homeowner is subject to not knowing what to look for on their roof simply because they do not have the needed knowledge and most homeowners do not want to walk on their roof. Sometimes the homeowner, through no fault of their own just assume that the roof that is on their home will last for the set number of years they are told, say 20 years. But in reality, the roof is just like anything else, it needs regular maintenance and yearly inspection to ensure that the home is being protected by a sturdy and secure roof.
Homeowners that make the extra effort to learn about their roof system, how it works to protect their home and what danger signs to look for can catch a potential problem before it becomes too serious.
