Got the whole suburban roof covered with dynamat. All I gotta say is I'd rather be busting rivets out of frames lolol. What a pain in the ass, the roof braces made it a slight challenge, more annoying than anything. I thought I was doing the whole roof in one night...HAHA what an IDIOT! I got halfway through the first sheet and my arms were dyin lol. I finished two the first night, did one sheet quick another night, then I just did the last two sheets last night.
24x48 is the perfect size, unfortunately you can only get that size in a 9 sheet pack. 5 sheets almost perfectly covered the entire roof. If I woulda taken more time to get minimal overlap it would have been perfect, but no worries.
Before this, any kind of rainstorm it was SO loud inside, couldn't have a normal conversation. Now it's easy to have a normal conversation in a downpour. Huge difference in sound and temp. I gained decibels(sound system) and i lowered decibles(ambient noise). Single layer roofs are the devil. I hope I never have to build another suburban again lol. If I do itll be a barn door.
