City staff recommends awarding fire station roof work to low bidder; insurance to cover replacement minus deductible

Public Works Director Hans Mercer told the council that a Sept. 12, 2024 hailstorm damaged city roofs and vehicles and that insurance inspected city buildings and issued replacement estimates and a payment net of depreciation and deductibles.

"Hailstorm occurred on 09/12/2024, approximately 03:02PM, causing damage to vehicles and buildings," Mercer said, showing photos of damaged membrane roofing and describing the insurance process. Mercer said the city advertised the work, held a pre-bid walk-through and received multiple bids; he identified a low bid from Dave Loden (reported in the staff slide as $140,885) and said the low bid came in slightly under the insurer's estimate.

Mercer recommended awarding the fire station roof project to the low bidder and asked council to allow Public Works to act on behalf of the mayor for project matters. He said the insurance proceeds will fund the work, minus the policy deductible.

Council members asked about contractor and material warranties, expected life span of the membrane roof and the project schedule relative to winter weather. Mercer said workmanship warranties are typically shorter (he would confirm the exact contractor warranty by email) and that material warranties for the membrane are commonly longer and may be similar to laminated-shingle product warranties in the 30- to 40-year range. He said the hail damage produced surface impressions that can lead to future leaks when UV degrades the membrane, and staff do not believe the hail immediately caused active leaks.

No formal award vote was recorded at the study session; staff presented the recommendation and said they would return with final contract details and confirmed warranty/product information.
