When considering the cost of roofing materials, many people take into account just the shingle prices. This is incorrect, as a roof made just of roofing shingles will not work. You also need to consider all the accessories that are included in a complete roof system.
Business letters tend to have both the sender and receiver's address and the date at the top of the page and they begin with a polite salutation, such as dear Mr. and Mrs, followed by a blank line before the body or the content of the letter.
The greeting in a business letter is always formal. It normally begins with the word Dear and always includes the person's last name. It normally has a title. Use a first name only if the title is unclear--for example, you are writing to someone named Leslie, but do not know whether the person is male or female.he greeting in a business letter is always formal.
