How To Prevent Transmission

You cant catch shingles, and you cant give shingles to someone else. But you can give others chickenpox.

After you have chickenpox, the varicella-zoster virus stays dormant in your body. If this virus reactivates, shingles occurs. Its possible to transmit this virus to others who arent immune while the shingles rash is still active. You are contagious to others until all areas of the rash are dried up and crusted over.

To catch the varicella-zoster virus from you, a person has to have direct contact with your rash blisters.

You can help prevent your transmission of the varicella-zoster virus by:

  • keeping the rash loosely covered
  • practicing frequent handwashing
  • avoiding contact with people who may not have had chickenpox or who havent been vaccinated against chickenpox

Concrete And Clay Tiles

Clay tiles are an excellent roofing option for premium homes. Clay tiles are heavy and require a specially designed roof frame to support the weight of the roof.

A properly installed clay tile roof should last anywhere from 50 to 100 years.

Clay tiles normally have really good wind uplift ratings up to 120-130 MPH, but any cracked and loose or missing tile pieces can create a hazardous situation during a hurricane.

Concrete tiles are like clay tiles in many regards including their heavy weight. They are however a less costly tile roofing option, with an expected lifespan of 40 to 75 years.

Tell-Tale Signs to Consider Replacement: Many cracked or loose tiles and/or leaks that dont respond to simple repairs.
