Stained-Glass Window & Roof Inspections
Trinity United Methodist Church
April 18, 24 & 25, 2013
On April 24, 2013, an architect with the Idaho Heritage Trust inspected and assessed the condition of the stained-glass windows at Trinity. In addition to inspecting the stained-glass windows, other architectural features of the building, including pointing, moss growth and wooden-framed windows, were also evaluated.
Additionally, a roof inspection was conducted on April 18, 2013 by representatives of the Trinity United Methodist Church Trustees and the Trinity Maintenance Engineer. On April 25, a representative from Robinson Roofing in Blackfoot performed an inspection of the Trinity roofs to assess water leaks and provide a bid for repairs.
Observations made during the inspection of the stained-glass windows and other features of Trinity Church are summarized in Part I of this report. The observations from the roof inspections are summarized in Part II. Photos documenting the conditions observed during the inspections are included as Attachment 1.

Trinity Church Roof Inspection
Locations Where Water Was Observed Inside the Church Building
1. North Ambulatory (lower) Tower Roof – A leak occurred this winter, causing damage to lath and plaster ceiling over the ramp inside the front (ambulatory) of the building. The leak may have occurred around the metal drain trough from west side of the tower. The current roofing material is asphalt.
a. Cost to repair existing roof
b. Cost to install new membrane on the tower roof.
Concern: How to deal with the drain trough from the tower onto the north aisle roof, so that potential for future leaks is minimized.
2. North Aisle Roof – The current roofing material is asphalt. No known leaks in this roof.
a. Cost to install a new membrane on the aisle roof.
Concern: Maintaining the openings in to the two drain troughs and two overflow drains as large as possible and preventing future leaks around them.
Concern: Large icicles build up on the high drain troughs from the main (central) roof during the winter. The icicles may fall and damage the aisle roof. Do you have any suggestions for how to prevent or manage this problem?
3. High North & South Towers – some water leakage seems to be occurring from the tower roofs. The leakage has been minimized by the heat tape on the asphalt roofing and into the drain troughs.
a. Cost to install new membranes on the tower roofs.
4. South Aisle Roof – The current roofing material is a membrane. A small leak occurred under the west stained-glass window this winder. (Some water streaking exists under the middle stained-glass window, but may be coming from the window and not the roof.)
a. Diagnose the cause of the leak and propose repair, including cost.
Concern: Icicles build up on the drain troughs from the main (central) roof during the winter. The icicles may fall and damage the aisle roof. The icicles on the south side are not as big as those on the north side. Do you have any suggestions for how to prevent or manage this problem?
5. North-west Corner of Parlor Roof – Potential leak in the roof causing paint to peel inside the parlor.
a. Diagnose the cause of the leak and propose a repair, including cost.
6. West-Side of Education Building – wooden soffits may show some water damage and white streaks on concrete blocks indicate possible leakage. It is possible that the damage to the soffits and white streaks may have been caused by leakage before membrane was installed.
a. Inspect membrane liner and determine if any leaks are present.
