Asphalt Flat Roof Repair

[nick1854]

So I can't ignore my leaking flat roof anymore. It is a 1950s build with a concrete roof, parapet walls, cavity walls with asphalt laid on the roof and the insides of the parapet walls and topped with coping stones. In places the asphalt is peeling away from the parapet wall and there are a few places with tears on the horizontal surface. I am not sure what is going on under the coping stones, but will have a look today. I am trying to decide the beat way to repair, and think it is beyond local patch repairs now. Can I apply a layer of some bitumen based felt roofing directly onto the asphalt? I suppose I could do this with EPDM or fibreglass as well, but maybe not straight onto the asphalt?

I know you will want photos and will try and get some posted.

Thanks

It's replace not repair that you need.

There are systems available specifically for asphalt overlay . Obviously they need to be laid correctly. A good felter should know
