Roof Shingles

bad asphalt shingles

There are a wide variety of composition shingle roofs, which are comprised of asphalt or fiberglass materials impregnated with mineral granules that are designed to deflect the deteriorating ultra-violet rays of the sun. These roofs are warranted by the manufacturer to last from twenty to thirty years, and are typically guaranteed against leaks by the installer for two to five years. The actual life of the roof will vary, depending on a number of interrelated factors besides the quality of the material and the method of installation. Poor roof maintenance is the most common cause of roof failure, but a southern exposure can cause a roof to deteriorate prematurely, as will the practice of layering over another layer of roofing material.

However, the first indication of significant wear is when the granules begin to separate and leave pockmarks or dark spots. This is referred to as primary decomposition, which means that the roof is in decline, and therefore susceptible to leakage. This typically begins with the hip and ridge shingles and to the field shingles on the south facing side. This does not mean that the roof is ready to be replaced, but the areas that are causing the roofing shingles to deteriorate should be corrected immediately. Regular shingle maintenance will certainly extend the life of any roof, and will usually avert most leaks that only become evident after they have caused other damage inside your home. This is important because in accordance with the home inspection industry standards, my home inspection does not include a guarantee against roof leaks. For such a guarantee, you would need to have a roofing company perform a water test and issue a roof certification. However, the sellers or the occupants will generally have the most intimate knowledge of the roof; I recommend you ask them about its history.

Here is what my clients have to say about my home inspection services:

Press F5 (on your keyboard) for additional testimonials

Buying a home is arguably the most important, exciting and nerve-wracking purchase a person will ever make.  This is the reason you need a great home inspector, and Dave Valley is just that.  He is empathetic – he understands and appreciates the various emotions a potential home-buyer goes through.  Most importantly, Dave provides you with objective information so you can make the most informed decision possible. 

 

It was a pleasure working with Dave – he contains all the qualities that make a great home inspector – he is the consummate professional, prompt, courteous, meticulous in his detail and honest.  Dave was reasonably priced – in fact Dave charged me the same amount I spent 10 years earlier on a smaller house and provided a far better work product. 

Prompt

I arrived at the house at the agreed upon time on a cold and nasty day, and found Dave outside inspecting the exterior of the home.  He was already a half hour into his inspection – I think this exemplifies and is symbolic of the fact that Dave is respectful of his client’s time. 

Courteous

Dave was pleasant to deal with, personable and thoughtful not only to his client but also to the buyer’s real estate agent.  

Detail-oriented

Dave spent almost four hours in his investigation of a 2,000 square foot house.  He answered all my questions and reviewed every observation he had with me.  David provided a detailed report, and encouraged me to call and email him to discuss the report and to ask questions. 

Conclusion

The highest compliment I can give Dave is to say that I would use him again and will encourage and recommend him to others.
