Hello, Trying to learn about all that's involved before starting to contact Contractors to re-shingle our roof. Typical Colonial in New England. I remember from years back that it was always suggested to Never re-shingle new over the old existing ones. That they should all be stripped off first. Why is this "so-important" ? If they are still flat, why not just put and fasten the new ones on top ? What else should I be asking the potential Contractors ? Are there different quality levels, e.g. ? Are GAF still considered the best ? Different thicknesses and qual. levels avail. ?? Do they still put rubber sheeting up from the gutters to some distance ? How far is good ? What should I be sure to get, brand, qual level, etc., and what might be good to avoid ? As always, thanks for help. Great Forums here. Regards, Bob

[color=#222222]I have this spigot on my roof. What would the base, where the pipe meets the roof, be made of? I need to redo that. I'm pretty sure it leaks there. You can see some of the rubber already lifting, but that square base should have been tapered to prevent water sitting there. There are a bunch of pinholes in it. The pipe flashing boots I've seen at Lowes are for larger pipes.[/color] [img]https://cimg0.ibsrv.net/gimg/www.doityourselft.com-vbulletin/552x636/pp_6fd016667c47f277d3bd075817af00a17bf13367.jpg[/img] [img]https://cimg3.ibsrv.net/gimg/www.doityourselft.com-vbulletin/446x292/pp_copy_3e7c17524ce4880154b1b55cf96eb0ca7687f3a8.jpg[/img]
