Background Discussion:
Fire Station 55 was constructed in 2007 and had a 15-year-old built-up bituminous flat roof on two (2) of its buildings at the station. Both roofs had experienced significant damage, which could be seen through the blistering on the roof likely caused by saturated insulation below the modified membrane. The blistering is caused by moisture getting in under the roofing and expanding like a balloon when the roof gets hot in the summer. This damage caused the roof to leak into the building during rainstorms. This caused minimal damage to the interior but if allowed to continue could have caused significant damage to the buildings. The roof had a material/manufacturer warranty for 20 years however it was not the roofing material that had failed it was the installation of the roofing that had failed. The construction/installation had a typical two-year warranty. The blistering on the roof began approximately four years ago and had become increasingly worse despite staff’s efforts to provide maintenance to the areas of concern.
Last year’s inspection indicated that both roofs needed to be removed and repaired. Through a reductive change order and per the contractor’s recommendation, a polyurethane roofing system was applied to both roofs. This is a new roof, but it did not require the removal of the old roof which saved time and money. The project is now complete and withstood the heavy rains we recently experienced during the February and March 2023 Storm Events with no leaking. The roof has a 20-year material and labor warranty and a 2-year contractor warranty.
Change Orders
The Fire Station 55 Roof Repair Project had two change orders. The first came before the Council with the award of the bid in the reduction amount of $90,238.00. The second was a zero-cost change order that extended the contract until April 21st. The contract was extended due to weather conditions, the polymer in the roofing system required a 70-degree temperature to fully cure. The polymer is applied in layers and the last layers were postponed until warmer weather became available. The project was completed in late March 2023 and within the contract specified time.
