Asphalt Roof Defects

Defective asphalt shingle products of either organic or fiberglass based shingles may experience several failures including cracking tearing granule loss blistering etc.

Asphalt roof defects.

They generally have sharp edges and vertical sides near the top of the hole. Common asphalt shingle failure factors include improper storage and handling of the asphalt shingles before installation improper nailing improper flashing which pertains to any roofing material and defective asphalt shingle product material leading to thermal splitting cracking blistering staining and in some cases curling or cupping shingles. Unfortunately this means that your asphalt flat roof has deteriorated past the point of no return and will need replacement. Asphalt detailing around roof lights as found that sometimes the asphalt detailing around roof lights can be a weak area possibly because a roof light is literally an opening in the roof and may deflect slightly more than the rest of the roof particularly if the water ponds around the roof light which it often seems to do.

So splits or cracks can occur in both organic mat based and fiberglass mat based asphalt roof shingles. This occurrence is often challenging to prove as some manufacturers are unlikely to own up to this. Manufacturing defects can occur which could cause thermal splitting and premature material cracks. Just like any roof a flat roof.

Small bowl shaped depressions in the pavement surface that penetrate all the way through the asphalt layer down to the base course. One last consideration to remember is that some issues may be due to a manufacturer s defect of the product. Surface cracking may be caused by shrinkage of the asphalt. Cracking of asphalt can be surface cracking or it can penetrate through the whole surface and expose the supporting layers.

If the cracks penetrate the surface it suggests movement or even failure of the structural elements of the roof. Designs where there is much penetration such as numerous nail holes multiple valleys drainage and the amount of materials used are more. Asphalt detailing around roof lights as found that sometimes the asphalt detailing around roof lights can be a weak area possibly because a roof light is literally an opening in the roof and may deflect slightly more than the rest of the roof particularly if the water ponds around the roof light which it often seems to do. The roof overheated melted the asphalt and caused granule loss.

Leaks and moisture probably the most common problems with flat roofs leaks and lingering moisture are issues that can be dealt with effectively as long as you stay on top of them. Potholes are the result of moisture infiltration and usually the end result of untreated alligator cracking.
