We have a technique that we can install a rubber roof over such a gravel roof at a relatively low cost provided the flashing is in good shape.

Most of the time flashing is made of copper and is well preserved.

The other factors would be skylights and other obstacles on the roof that could make it hard to reach the flashing.

The old roofs are fast being replaced by rubber roofs. There are several ways to go about replacing such a roof.

Most roofing companies would recommend to remove the old roofing material to the deck, which could be tongue and groove boards or plywood, and then install a new rubber roof. That is the preferred way to do it. It is also much costlier to do. More people are involved stripping the roof and removing the debris. A dumpster has to be ordered. Then the possibility of damaging existing flashing while removing the old roof is also a factor.

Most of the time we will recommend to install a rubber roof over and existing gravel roof. We have done this with most of out projects and it is perfectly alright to do so. The problem sometimes is if there are many skylights on the flat roof. Anytime you go over an existing flat roof, you need also to tie into the flashing of the old existing roof. That flashing is buried under the old roof surface and has to be exposed to adhere the new rubber roof to that.

The most time consuming part of a roof are the drains, air conditioners and flashing.
The roof is ready to receive the final membrane. Notice that the base sheet is under the flashing.
