I've been in roofing for about 5 years now. We've done extremely well in the residential and commercial roof replacements and have built a large network of very reputable gc's who are always wanting us to bid on their new construction projects. While this is something we're very interested in and would like to pursue we've never really bid jobs from prints and it can be slightly overwhelming and confusing. Obviously things are broken down by section based on trade but I feel like the margin of error is high and mistakes could be very costly. Any help simplifying things would be of tremendous use. How do you know exactly what is covered in each section you plan to bid? For instance is the roof deck supposed to be installed by the roofer or framer? Metal flashings, Gutters & Downspouts, ETC.? Again any help will be greatly appreciated.
