Replacing a roof is something
most homeowners do only a few
times in their lives.  Do it right, and
you will add decades of beauty,
comfort and energy efficiency to
your home.  If done wrong, you
may end up multiplying your initial
investment in repeated repair
costs.  Generally speaking, new
shingled roofs should last upwards
of 20+ years.  However, many
factors, such as proper installation,
climate, and ventilation, impact the
life of your roof.
Even if your roof shows signs
of the symptoms mentioned
in this image, you may not
need a total roof replacement.
 A trusted roofing professional
from Roofing by Petty can
give your roof a thorough
examination and let you know
if you are in need of a new
roof, or just a few repairs.
  1. Algae growth causes a dark discoloration on roofs. The algae is usually brown to black in color
    which results in a streaked, dirty looking rooftop.  It can be mistaken for soot, dirt or tree droppings,
    which typically produce only localized discoloration.  It's caused by the growth of air-borne algae
    which deposits on your roof.  The good news is that algae growth does not affect the service life of
    your roofing material.  It occurs most often in warm, humid climates such as the Southeast.
  2. Damaged Flashing is caused by improper installation on a new roof, drying and cracking on an old
    roof, improper nailing during installation, and settling of the structure.
  3. Buckling is caused from improperly applied felt, wrinkled underlayment, roof deck movement,
    spacers not used in between roof deck boards, poor roof ventilation, and new shingles applied over
    old, rough shingles.
  4. Curling is caused from high nails, lack of back coating, under-saturation of asphalt felt in organic
    shingles, lack of ventilation, and improper number of fasteners.
  5. Blistering results from moisture in the shingle.
  6. Missing shingles indicate improper fastening during installation or exposure to high winds.
  7. Ceiling spots are caused by leaks in the roof which seep into your ceiling.
  8. Normally a certain number of granules will be loose, especially after application.  These granules are
    called "riders" and are a normal result of the manufacturing process.  Granule loss does not affect
    the service life of the shingles unless granules can be seen missing on the surface of the shingles,
    thus exposing the asphalt.
  9. Rotting is caused by absorption of moisture by the mat at the core of the shingle. This is a common
    problem with organic-based shingles.
