A lot of homeowners will watch what their roofing contractors are doing. They want to be sure that the roofing repairs are done effectively so that they do not have any leaky roofs after the job is complete. What may surprise you, however, is that as you watch the contractor's crew work on your roof, they appear to be repairing parts of the roof that do not leak. You may find this frustrating, or you may be upset and think that you are paying for repair work that is not necessary. Actually, what the crew is doing is necessary, and here is why your contractor is repairing parts of the roof that do not leak. 

Leaks Are Never a Straightforward Thing

This is a roof. With the exception of the flattest of roofs, leaks do not occur as a straight-down, through-the-roof sort of thing. The leaks almost always come from a point higher up on the roof. The water gets in there and flows downward until it reaches a weaker spot, and then pools to break through your ceiling. Ergo, when your roofer is removing shingles and replacing parts of the roof that are higher up than the areas where the actual leaks are, he/she is doing exactly what needs to be done to fix a leak. 

Your Roof Is Getting Added Protection

Not only is the roofer fixing the present leak by fixing the roof that is higher than the leak, but he/she is also improving parts of the roof above the leak so that leaks cannot occur again for a long time. In short, your roof is getting some much needed added protection. The higher up he/she goes, the more this area of your roof will be protected for the next decade. 

Mold and Rot Do Not Understand Directions

When you have soggy roof boards, mold and rot develop. The mold and rot travels up and down the lengths of the affected boards. It would not matter if there is not a lot of moisture up higher. Mold and rot do not understand directions, and they travel the length of the boards because they can. When your roofer pulls back the shingles and underlayment, he/she might uncover some rot that has traveled up higher than expected. Hence, your roofer instructs his/her crew to remove all of the rotten wood and replace it before repairing the rest of the roof.
