Composition Shingle Roof

Causes<p><li>Improper installation on a new roof<li>Drying and cracking on an old roof<li>Dented by improper nailing<li>Settling of the structure Causes<br>Improper nailing, improper installation pattern, drying and cracking and wind. Causes<br>Could indicate a leak in either the shingles or flashing. Causes<br>Improperly applied felt, wrinkled underlayment, roof deck movement, spacers not used in between roof deck boards, poor roof ventilation, new shingle applied over old. Causes<br>The intense ultraviolet rays of the sun cause the majority of the damage.  The shingles can lose just about all their moisture causing cupping and curling. Causes<br>Poor attic ventilation. Causes<br>Shingle have reached or exceeded their useful life. Causes<br>Moisture in the shingle.  Either the shingle is breaking down and not performing the way it should or there may have been moisture trapped in the shingle during the manufacturing process.  Bad ventilation, leaking and other common moisture infiltration can cause blistering as well. <b>Causes</b><br>Algae growth causes a dark discoloration on roofs.  The alga 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 life of your roofing material.
