Re: First shingles outbreak - genitals! I can't imagine the pain of having Shingles in the area you have. I had the pain in my right knee and hip and right side of my butt before any rash appeared, so Shingles was my last thought once the rash appeared, thought i had a allergic reaction to some bug bite. I get a quarter size patch of very tiny blisters - about an inch above my butt crack. The fluid is clear when popped and takes almost 2 weeks for the area to heal. I of course shower and clean myself properly so I have no idea what the heck it is. Using a cotton ball soaked in the ACV remedy, apply to the itchy rash on your buttocks and in your butt crack and let it dry. Use the healing solution 2-3 times a day to get rid of a fungal or bacterial infection from your buttocks.

Asphalt shingle cracks due to thermal splitting & defective product: this document tells readers how to identify & explain asphalt shingle cracking or thermal splitting, what causes shingle cracks or splits,and how to distinguish this product failure (which may be entitled to a warranty or class action claim) fromother roofing product failures or defects.

FIBERGLASS SHINGLE CRACKS - Thermal Splitting Asphalt Shingle Crack & Tear Failures Described & Explained

Fiberglass-based Asphalt Roof Shingle Cracking/Tearing/Splitting Failures

'Thermal splitting,' or 'cracking' which in fact is in most cases actually atearing of the shingles is considered by experts to be the principal currentproblem with fiberglass-based shingles. We prefer the term tearing as a mostaccurate description of what's probably happening. Originally observed on thelightest-weight (15-year life) shingles this problem has now been found acrossall shingle styles, weights (life ratings), and we suspect, probably acrossmost or all manufacturers of this type of product.

The thermal expansion of defective asphalt shingle product (common in the U.S. across many manufacturers in the early 1990's) followed by thermal contraction when cool weather approached, explained the tear shown in the shingle in our photograph just above.

See THERMAL EXPANSION of MATERIALS for a table of the coefficient of expansion of common building materials. We have not found a source defining the coefficient of thermal expansion of asphalt roof shingles - Contact Us if you can provide that information.

Does Thermal Splitting or Shingle Cracking Tearing Occur only in 3-Tab Asphalt Shingle Roofs?

No. Thermal splitting or tears occur in both conventional 3-tab shingles (photo above) and also in laminated asphalt shingle roofs.

Our photo (below-left) of thermal split/tear damage to a laminated asphalt shingle roof was provided by ASHI Home inspector Steve Mauer.

This unfortunate roof, inspected by Mr. Mauer in 2009, also suffered from granule loss (below-right) that in our OPINION looked like a defective product.

The same roof also included a damaged shingle that looked like a cracking and granule loss problem combined, but we think this was a shingle splice created at the factory during production - a bad individual shingle that is sometimes created when ends of shingle production substrate are spliced together. See SPLICE DEFECTS on ASPHALT SHINGLES

What Does Shingle Cracking or Shingle Splitting Look like?

Watch out: as we warn at ASPHALT SHINGLE FAILURE TYPES if conditions prevented the home inspector from direct access onto the roof or at least a look from a ladder set against the roof edge, shingle damage, cracks, and splits such as that shown in own photo (at left) could have been difficult or even impossible to spot. Inspecting the roof from the ground, even with good binoculars, can't show all roof damage types and conditions.

We have observed a variety of torn or split asphalt roof shingles, illustrated by our photographs below. (Click to enlarge any image.)

Horizontal Cracks & Splits in Asphalt Shingles

Both thermal splitting and other shingle cracks and splits can also occur in a horizontal pattern as we illustrate in our photographs below.

The horizontal cracking occurring in these fiberglass-based asphalt shingles resulted in complete loss of some of the shingles from the roof surface. The silicone caulk was placed by the owner during an attempt to 're-glue' the lost shingle tabs. But using our pen we pointed out additional horizontal cracks and tears developing in the next course of shingles just below. From a the ground the lost shingles looked like an isolated problem. An on-roof inspection told a different story.

Both horizontal and diagonal or vertical tearing may occur in the same roof as we illustrate in our photo at left (Click to enlarge).

What is the Cause of Thermal Splitting Cracks in Fiberglass-based Asphalt Roof Shingles?

Our photos above demonstrate two classic thermal split patterns in fiberglass based asphalt shingles: vertical splits running straight up the roof (above left) and diagnoal splits following butt joints (above right).

• It's possible that shingles made by some manufacturers do not meet the ASTM Standards for tear resistance.


• Even where shingles meet the Standards, it's possible that the standards themselves were defective. In particular, for a time the asphalt roof shingle standards combined these concerns:
  • A thin fiberglass mat was permitted as the shingle substrate, lacking adequate tear resistance
  • The wind uplift prevention bonding adhesive was too strong, causing the shingles to bond into nearly a single continuous surface that lacked adequate movement to respond to significant changes in temperature without tearing the bound surface
  
  
• In any case, Fiberglass mat may lack adequate tear resistance


• Self-sealing tabs on shingle backs may glue shingles together with too much strength, causing the roof covering to form a single large membrane which cannot accommodate large temperature changes. This explanation was discovered across the asphalt shingle industry.


• Reduced total amount of asphalt in thin fiberglass mats might become brittle after exposure to heat and sunlight


• Temperature swings probably contribute to the onset and extent of tearing, and we'd expect worse tearing where temperature swings are more extreme such as in Northern climates.


• Nailing or placement pattern of shingles: 'laddering' vs. 'staggered.' On laminate and strip type shingles we have inspected roofs on which damage is found occurring at the corners of shingles rather than in the middle of the shingle material. It appears that as temperatures dropped and the glued-together-roof-membrane cools and contracts, the natural point at which movement occurs is where shingles are end-butted together.
  When the pattern of end-butts is laddered rather than staggered up the roof we have found corners tearing off of shingles following the laddering pattern exactly. (Laddering is not a recommended installation pattern according to NRCA and ARMA publications nor according to instructions from some manufacturers.)
  Laddering alone cannot be blamed for this failure however, as we have seen similar shingle tearing following a staggered end-butt pattern up other roofs. However laddering may indeed create a more localized natural point of separation on a roof, causing most of the movement to occur in a smaller area when the roof material contracts with cooling.

Splits or Cracking in Organic Asphalt Shingles

Organic mat asphalt shingles also may show cracking and accompanying granule loss. Defective asphalt shingle products of either organic or fiberglass based shingles may experience several failures including cracking, tearing, granule loss, blistering, etc. So, splits or cracks can occur in both organic-mat based and fiberglass-mat based asphalt roof shingles.

See ORGANIC FELT SHINGLE NORMAL WEAR for details about normal wear splits or cracks and granule loss in organic roof shingles.

Also see ORGANIC FELT SHINGLE DEFECTS for other wear signs on organic mat asphalt shingles.

But thermal splitting is particularly a problem with fiberglass mat based asphalt roof shingles. The catastrophic early shingle splitting failures like the ones illustrated earlier in this article were principally a problem of lightweight, fiberglass-mat based asphalt roof shingles made during the period discussed above. Roughly, from 1992 - 1997.

Nevertheless, fine cracks through roof shingles, regardless of cause, mean accelerating wear rate and on a roof like the one shown at left, the roof needs replacement.

Cracking due to cold weather installation & bending ridge or hip cap shingles: see RIDGE & HIP CAP SHINGLES for additional discussion of distinguishing cracking wear failures from other types of shingle failures.

Also see ASPHALT SHINGLE PROPERTIES and see Choosing an Asphalt Shingle: Organic vs. Fiberglass, Ted Cushman, The Journal of Light Construction, May 1993 for more about the debate around the advantages and disadvantages of organic mat asphalt shingles vs. fiberglass mat-based asphalt roof shingles.

  If you have never fixed a roof tile or slate before but have wondered how to go about repairing or replacing them, then this is the book for you. Many of the technical books about roof tiling and slating are rather vague and conveniently ignore some of the trickier problems and how they can be resolved. In Roof Tiling and Slating, the author rejects this cautious approach. Kevin Taylor uses both his extensive knowledge of the trade and his ability to explain the subject in easily understandable terms, to demonstrate how to carry out the work safely to a high standard, using tried and tested methods.
  This clay roof tile guide considers the various types of tiles, slates, and roofing materials on the market as well as their uses, how to estimate the required quantities, and where to buy them. It also discusses how to check and assess a roof and how to identify and rectify problems; describes how to efficiently 'set out' roofs from small, simple jobs to larger and more complicated projects, thus making the work quicker, simpler, and neater; examines the correct and the incorrect ways of installing background materials such as underlay, battens, and valley liners; explains how to install interlocking tiles, plain tiles, and artificial and natural slates; covers both modern and traditional methods and skills, including cutting materials by hand without the assistance of power tools; and provides invaluable guidance on repairs and maintenance issues, and highlights common mistakes and how they can be avoided. The author, Kevin Taylor, works for the National Federation of Roofing Contractors as a technical manager presenting technical advice and providing education and training for young roofers.
