Ladder feet dents in flat roof felt

[padul]

I employed a roofing company to look at our roof.
When using a ladder to reach a high level the feet dented the flat roof in eight places.i attach a photo that shows two of them. They haven't punctured the felt. How should I repair them.?

 

[Wayners]

I'd phone the company that don't it. That's a poor effort. They should fix.
On a side note..
There is a metal brush now that is pulled across a flat roof and will spark where there is a hole. Around 200 holes in a large flat roof were found when the above roof was slatted.
Damage caused by a roofing company when they repaired the slatted roof.
Crazy.
You need that repaired..
Black jack or similar.

I think they were a dodgy company. They haven't replied.

Never heard of this, sounds interesting, can you elaborate?

Anyone with that level of incompetence you should then get rid of them.
If I were fixing it, I would get my blow torch out, but since you are diy, use acropol.

Are you concerned about the visual appearance or water ingress? If the latter you can patch felt roofs.

 

[padul]

I guess a bit of both but water ingress is my main concern.

@catlad

It's cleaver and really works
Found over 200 leaks

Hopefully not on one roof!

 

[Wayners]

Yeah. Was on a large flat roof. Cutting and working with slate on the flat roof

 

[catlad]

Wow! Did you buy one of these detectors?

 

[Wayners]

I don't have one. The company that was given the repair contract had one.
They patched up holes which took days but it's worked.
So felt can be repaired.

 

[Alastairreid]

Seen them being used on commercial jobs by surveyors (hospitals) cost thousands for a decent detector which wouldn't really be viable for a roofer doing domestics.

 

[catlad]

Ahh, well, I'll put it on my Christmas present list.

Looks like very high voltage, but that would have to be between the brush, and the under surface of the roof. I cannot really see how it would work, no sign of the high voltage generator, or wires to the brush, or the roof?
