Compare appearance of original existing integral eavestrough on main building (on left) versus new types of eavestrough system on garage building (right)

Cross section of existing eavestroughs on left and proposed on the right, shows how the new system removes the decorative moulding (replaces it with plywood), infills the existing gutters and extends the drip edge to new eavestroughs of different design and profile. (Source: A. Coates).

However, Dayus roofing contractor has indicated that retaining the existing built-in eavestrough would require re-lining the existing system (quoted for $7,497.90) and additionally noted that the wood underneath is in very poor condition. Dayus has told the Owner that the repair option may further damage existing wood, and may open “a can of worms” and result in much more cost to the repairs. Dayus strongly recommends the Owner to install the new system instead of repairing the existing. Unfortunately, due to the ongoing Coronavirus pandemic, there has been little ability to verify the condition and there has also only been one quote received from Dayus Roofing for the eavestrough work. The Owner is very confident of and agrees with the recommendation of Dayus Roofing. Besides the concern with uncertain costs of retaining the existing eavestrough system, the Owner also prefers the new system as it offers a leaf-guard protection which would lessen the burden of maintaining the eavestroughs and prevent water back-up along the wood fascia. It is her opinion that the primary focus of the decorative element is the consistent pattern of the dentils below the eaves, which would be retained.
