Tackling problems at an early stage and having a professional fix them will cost you money in the short run but not nearly as much as if you were to allow the problems to progress to a critical stage, such as rot.
Attic Moisture
Moisture can accumulate in an attic that is poorly ventilated. This, in turn, may lead to decay, according to the Grace at Home website. For increased ventilation, install additional vents, or have a professional do so if you are not proficient enough to handle the job yourself. Look for signs of poor ventilation when it rains. Water droplets will usually be found in your attic.
Missing Tiles
If you have one or two tiles, or shingles, missing from your roof, these are early signs of a potential roofing emergency. The Check Your Roof website suggests contacting a professional right away. In the absence of adequate shingling, water could seep into your roof, compromising its ability to protect your home from the elements.
Spots
According to Check Your Roof, besides being an eyesore, such spotting can indicate a weakness in your overall roofing. Spotting may indicate that water damage is present. If you discover even small amounts of spotting, call a roofing professional. A roofing expert can examine your roof to see if water has seeped deeper into your roof and into your house.
Rot
Rot is an emergency and you should contact a roofing professional right away. Your roof has undergone severe damage and can no longer perform the function of protecting your home. Your entire roof may need replacing, depending on the extent of the damage.
Curling and Buckling
This phenomenon occurs when hot air from an attic causes your shingling to curl away from your house. The curled shingles cannot adequately protect your home in this condition and are a sign of inadequate roof ventilation. Consequently, your cooling bills will skyrocket as your air conditioner has to do more work, and your roofing could expire years before the end of its natural life expectancy.
