Removing old shingles can be a lot of trouble for very little reward, and it can often seem as though it is easier to place the shingles over the top of the old ones. Before you start putting this into action, there are 1 or 2 things which you need to consider first.
Condition of the Roof
It is not enough to just place the shingles over the old ones, you have to first ensure that the roof is in a good enough condition. This may involve removing a small section of the roof in order to check that the condition of the shingles, and the support structures underneath those shingles. Look at the felt and the roofing materials, and check for signs of leaking before you start installing new shingles over the top.
