The copper wash at the China Trade roof directs a lot of water to a drainage grate below

Generally during rain storms work ceases– but for us at Historic New England, rain storms are a perfect time to review active drainage problems at the site as well as review the new roof work.  Slipping into some rain boots and a sou’wester hat, we venture out to look for problematic areas or sections that may need additional considerations– and of course, dreaded leaks.

The primary job of a roof is to keep out water and protect the interior contents.  The large area of a roof repels a lot of water but then it must be directed in some suitable way, so that it does not cause damage.  This can be complicated at Beauport– with 200 squares, nearly 30 roof penetrations, and an area with 19 intersecting roof lines– water run off and drainage is extremely important.  Understanding where water is directed on such an expansive roof is the key to keeping the interior dry.

Rain rushes off the Sun Porch Roof onto the garden beds below, which can damage plants

The small roof at the South Gallery Nook takes on a lot of water from the steep Blue Willow Room roof above

The gutter at the Pine Kitchen roof can't take the rain and it gushes over to the window opening below
