It would not be necessary, but preferable because additional work would be created at the openings for doors and windows because of the additional thickness being addes.
The condition of the shingles and wood underneath help to determine this. If the wood is good and shingles are mostly still there, some cities allow two or three roofs on top of each other before all of the shingles must be removed.
You should have the vaccine as an older adult if you had chicken pox as a child. Before shingles appear.
In case it rains before you finish shingling.
No. Shingles is not contagious, but someone with shingles can give chicken pox or varicella to someone who has not had chicken pox before.
No
Babies do not develop shingles before chicken pox. Vise verse is true.
No. You can however catch chickenpox from the shingles if you've never had them before. The shingles themselves come from a dormant chickenpox virus in your skin tissue.
If the shingles are buckled they need to be removed before applying new ones. If they are in fair shape, then keep the old shingles on if there is only one layer.
Shingles is not contagious -- it can't be "caught" from someone else. People with shingles can give you chickenpox if you haven't had it. See related link below for information on transmitting shingles
No, 'Shingles' itself is not a condition that can be 'caught'. When someone first catches the virus Herpes zoster, the first symptoms they will develop is what we call 'chicken pox'. However once this condition passes, the virus remains in the body, and can cause shingles to develop many years later. If you've never had chicken pix before, then you may catch it from an infected child. However if you have had it before, then technically you are still actually infected by the virus, and contact with the child won't cause you to get chicken pox again, nor can it trigger shingles to develop.
Shingles cannot be transmitted from person to person but the chicken box virus that causes shingles can be passed on to someone who has never contracted the shingles virus before. When the shingles rash has developed it is contagious but is not likely to be passed to another person if it is covered up.
My dad recently found out he has shingles and the doctor has told him he cant fly, my parents had a holiday booked 2 days before he found out he had shingles, even the place they booked at told them he has to wait a week before going away.
