Flat roof signs

[Warren Beard]

Can you not fix to the face of the building with the brackets extending over the top of the roof and attach the sign to that?

[David Lowery]

Fix direct to roof using rawbolts but before you tighten, use plenty of silicon sealant in the holes, under the metal frame then when bolted, more sealant around the edges of the frame.
That’s what I did some 8 years ago and there have been no problems as yet (he says with fingers and toes crossed)

If you dont want to drill into the flat roof which is understandable,
(Im assuming with letters that big you are making a metal box section frame in a right angle shape to fix the letters to?

It all depends what the roof is made from, is it pitch, concrete etc.
If it was concrete I would use 6" blocks or kerb stones cemented to the roof and fix to those with heavy duty bolts.
Then cover with a fascia if they are visible from the ground.
What I wouldn’t do though is drill into his roof, if he gets a leak which in turn turns into a roof brought down by water damage, you are likely to get blamed no matter how much silicon you have put in.
If its a pitch roof, I would be wary of fixing into it at all, weight onto the frame to weigh it down like blocks or sandbags etc, if someone got up there and decided to pick one up and the sign came down guess who’s to blame.
Id go with big flags

Thanks guys for the replies

Steve you may have something – I wasnt going to using individual letters but thinking maybe vinyls on dibond secured to a frame and hence I like the idea of freestanding kerbstones whatever that you then fix into

Keep the ideas coming if someone has done it differently

Thanks again – John

Ive tried to buy sky hooks before once but everywhere is either out of stock or they just laugh at me,
I was going to get my long stand, and my diamond shaped roof tiles at the same time as well
😥

Incidentally the diamond shaped roof tiles is true.
My Mates dad actually sent him to Jewson for some and he actually waited while they looked at him like he was a complete basket case.

Well got to site with my bigger ladders and guess what – client was wrong, it isnt a flat roof at all grrr – its a very shallow pitch asbestos roof concealled from view behind a parapet wall so I’m going to tell the client sorry no signs on the roof and try to work out something like warren suggested ie sign protruding up from wall – so if anyone has an idea on that I would be interested.
I was thinking maybe vertical poles up from wall via key clamp system (like scaff tube) secured with rawlbolts and then sign blank with channel to the rear onto the posts – any thoughts will this work re wind load etc?

Thanks – John

No, I think your idea is excellent, I would go with scaffold poles in a frame type pattern.
