Porch roofs, additions and low-slope sections
Older houses often have a low-slope porch roof or a rear addition covered in rolled roofing, rubber or tar. These areas collect water, and the joint where they meet the main wall is a common source of leaks. Standard shingles do not belong on very low slopes.
A proper repair uses a membrane meant for low slopes and flashing that laps up the wall and under the siding. We look at these small roofs closely because they are often neglected, even on houses where the main roof is in good shape.
