I believe the hump you are referring to is the rafters of the roof. When they plywood covering the roof framework starts to sag from age, weather or due to poor construction, it will form high and low areas. Roofs that have this type of issue will normally have these humps at regular intervals. If you look in the attic you will see the roofs frame lines up with the spacing between the humps.
Underlayment is placed under shingles on a roof to provide an extra layer of protection and insulation.
There should be a layer of tar paper and then plywood.
Most will have a layer of plastic-like fabric underneath but older shingles may just have plywood underneath.

The only difference in the installation between the 30 year and the 50 year shingles is that the 50's are heavier and a little more work to hump up onto the roof and to cut.

To effectively clean roof shingles and maintain the appearance and longevity of your roof, you can use a mixture of water and mild detergent to scrub the shingles with a soft brush or broom. Rinse the shingles thoroughly with a garden hose. Avoid using high-pressure washers or harsh chemicals, as they can damage the shingles. Regularly cleaning your roof can help prevent moss, algae, and debris buildup, extending the life of your roof.
Slate which is a type of stone is used for the roof tiles instead of shingles. It splits in thin sheets and is nailed to the roof the same as regular asphalt shingles.
