Question 1

How often should you replace your home’s roof?

Residential roofs are typically replaced once every 15 to 20 years. However, damaged shingles can be replaced periodically throughout that time.

Question 5

What is the difference between reroofing and roof replacement?

Accepted Answer

Reroofing refers to the act of adding a layer of asphalt shingles over the top of the previously installed roof. A roof replacement occurs when the existing shingles are torn off before the new roofing system is installed. Typically, reroofing is the less expensive option. However, it can only be done if the existing roof is in good shape.

Question 6

How often do you need to reroof your house?

Accepted Answer

Technically, you may only need to reroof your house once every 40 years. However, remember that “reroofing” refers to adding another layer of asphalt shingles on top of the existing ones. Most local building codes state that a third layer of shingles cannot be added. So, the next time a new roof is needed after you reroof, you will need to hire a contractor for a roof replacement.

Question 7

Do you need to remove solar panels before roof replacement?

Accepted Answer

Talk with your local roofing company to see if their employees will remove and reinstall your solar panels. Some contractors are happy to perform this task for an added fee, especially since most mounting systems for solar panel systems are straightforward.

Question 8

How long does it take to replace the roof of a house?

Accepted Answer

Most residential roof replacement jobs can be completed in one day. However, this depends on the house size and whether you are paying for a reroof or roof replacement.
