1) Buckling - Buckled shingles are caused by improper ventilation. Built up hot air within the attic forces the shingles to bulge away from the roof. Improper ventilation can take years away from your roofs life, which in turn, means more money.
2) Algae - Those ugly black looking streaks or a "dirty" looking roof. This fungus is dangerous as it traps moisture underneath between it and the shingles. Trapped moisture is never a good thing as it is sitting water waiting to show itself on your ceilings.
3) Curling (or Cupping) - Another tell tell sign of poor ventilation. Curling is when the edges of the shingles look as if they are rolling up towards the top. Shingles take a lot of heat from the suns rays beaming down but when the temperature beneath them is to high they basically fry. When the edges curl, the seal strips begin to unseal, which allows for winds to easily blow the shingles off and makes it easier for water to find its way inside.
4) Damaged Flashing - Flashing seals around any projectile that are protruding the roof. If any flashing has holes, cracks or is in the least bit vulnerable, you are bound to see leaks. If you have faulty flashing and do not see any leaks, act fast, as they will rear their ugly heads very soon. Your roof is a highway for water, and these cracks, or holes, are the exit ramps to the roads straight inside your home.
5) Missing Shingles (wind damage) - Each shingle covers the nail heads to the shingle below it. When a shingle blows away or becomes missing, it exposes the nails (which are ultimately holes). Water can very easily find its way around the nail heads and straight into your home. Sometimes, when shingles blow away, they can take pieces of the felt paper with it, just like in the example. This person has exposed plywood and no protection against inclement weather.
6) Roof Rot - This "rot" is due to age. Wind damage can be mistaken for roof rot (or granule loss) due to wind blowing layers of the granules away. Asphalt shingles are made of densely compressed layers, and as a roof ages, those layers are slowly peeled away. As they become thinner and older, the shingles become more brittle and more prone to blow offs and leaks.
If you see any of these tell tell signs of a roof problem you should contact a specialist as soon as possible. Any and all of these common problems can quickly lead to serious damage to the decking, framing, and overall structure of your home. Staying cautious is always better than being careless, as catching a problem in the early stages can save you major bucks! We recommend having your roof inspected once a year or after severe weather, and of course if you notice something out of the ordinary you should act fast before your in deep water!
