Hi, Please be gentle it's my first post. I need help with Part L for flat roofs. I'll be honest, I'm an old school roofer who is trying to upgrade to 2013, but all I get is conflicting messages. I'm not sure if it's a localised thing but our Building inspectors don't give a hoot. I ask if it needs upgrading they say probably not. But hang on I'm stripping and re-felting an existing flat roof & over 25% falls under an upgrade, so how can this be & how come all the other roofers around here also don't give a hoot. I wouldn't worry about them if it wasn't for the fact they're under cutting me by a huge amount by not insulating. Customers only see the £ signs. So I ask you knowledgeable people, how an earth do you do this Part L with-out being penalised & are there any loop holes people are using (you can PM me those if you like
Thank-you.
