Jimmy F asked:

We have looked at going to a holiday camp like Pontins but none will take us without someone over 25. We are in Hertfordshire and want somewhere not too far to drive to (2-4 hours). We were hoping to find a good camp-site near the coast who take groups like ours. Any recommendations?

How Can You Recognize When a Roof Has Problems?

Andy Roofer asked:

Roof replacement is one of the scariest thoughts all homeowners will eventually face. Many roofers recommend a plan of preventive roof maintenance and repair to delay the need for a total roof replacement. By regularly inspecting roofs and making repairs as they are needed, many homeowners can extend the life of their roofs for many years, even for a lifetime.

However, though regular roof inspection is necessary, there are times when your roof may exhibit warning signs that it needs to be repaired sooner. Some of these warning signs include leaking that you notice after heavy rain. These leaks are noticeable in the attic. If you check in your attic and don’t see any leakage such as dripping, but notice that there are stains on the walls or ceilings, you will need to have your roof looked at by an experienced roofer. Don’t always expect to see bucketfuls of water before calling a roofing contractor. Wet stains are a sign that water is leaking past the roof and shingles and making its way past the underlayment. This must be addressed or the problem will only become worse.

Another sign that your roof needs repair is if you detect peeling paint on the exterior of your home. In addition, shingles may begin to show signs of damage or decay as well. If they slip, deteriorate or look damaged, then you should have a roofer inspect your roof. Some other signs that indicate your roof is damaged include high-energy costs and excessive mold, mildew, or fungus growth in your attic. Failure of proper ventilation is another sign that needs to be addressed by a roofing contractor. Just because you don’t see signs of leaking, doesn’t mean that your roof doesn’t need repair. Sometimes the damage may exist underneath in the structural layers, and these are just as serious as external damage.

Science help? Physics? Chemistry?

MikeDaIKe asked:

I’M HAVING A HARD TIME WITH THE FOLLOWING!! PLEASE HELP!

Can someone explain how the scientific defenition of work is different from the everyday meaning?

Can someone give me an example of a situation in which a force is applied but no work is done?

Which of the following situations is work being done?
A)A person shovels snow off a sidewalk.
B)A worker lifits bricks, one at a time, from the ground to the back of a truck.
C)A roofer’s assistant carries a bundle of shingles across a construction site.

Can someone describe to me the circumstances for which the output work would equal the input work in a machine?

How does lubricating a machine effect the output force exerted by the machine?

I’m having a hard time calculating the mechanical advantage of a hammer if the input force is 125 N and the output force is 2,000 N.

-THANKS IN ADVANCE!!!!

A question for roofers or insurance people?

Joel B asked:

I called a insurance person out to my home to look at my shingles because of hail damage. When I looked I thought the garage was not that bad but the house was really bad. The guy looked at them both and said he will cover the garage and not the house. The house has little spots all over the shingles that the rock is missing off them and there is also dents in all the metal vents. I don’t understand, I can see it, the garage is only 10 feet from the home, why would he do this, what should I do now.
