In this video, our principal surveyor – Steven Dickinson, explains problems with insulating a roof using the warm and cold roof construction methods.
How things change! When I first started out as a roofer I had to hand write estimates and send them by snail post to my customers. Slowly emails took over and now its emails and a short video.
First we clean the old asphalt roof then we work on the old asphalt up-stands you can see we have replaced them with wood and straitened them out this will make the new flat roof look better but also make it easier for us to apply the SD650 liquid roofing system.
Stripping the old system can work out expensive not only to the property owner but to the enviroment as the materials will all go to land fill when dumped. In the video I show you how we clean the top surface of an old asphalt roof and start the process of capping the old roof with one of the new liquid roofing systems the new SD650 roofing system from 3m.
In this video I explain problems with insulating a roof using the warm and cold roof construction methods. Whatever new flat roof covering you choose, e.g. EPDM rubber, Kemper, Liquid Rubber Triflex, if the specification of the insulation is not correct you could have problems which could include rotting joists.
The lead on these flat roofs is beginning to oxidise and break up before the end of its lifespan. Lead on roofs and flat roofs are supposed to last 30 to 60 years with very little maintenance. What we see more and more is lack of ventilation and roofs sweating; this problem is happening because of the lack of ventilation under the lead flashings.
