Assessment Lays Groundwork for Successful Roof Replacement

Well before a roof-replacement project can begin, maintenance and engineering managers need to lay the groundwork by conducting a series of processes that are designed to produce a successful project that delivers long-term benefits to the facility and the organization. These processes include the following:

Conduct a preliminary assessment:

• Core the existing roof system to evaluate the roof assembly and overall system height.

• Evaluate HVAC, plumbing and wall heights for possible conflicts with industry standard detailing.

• Identify areas of ponding water on the existing roof system.

• Note active tenant concerns.

• Assess the type of roof drains, the size of drain bowls, and provisions for code-required drainage, and perform proper flow testing.

Compile project specifications:

• overall site plan

• as-built drawings of the roof and drain locations, to scale if possible

• roof plan with walk path layout and applicable design details

• type of roof deck

• provision for overflow drains

• insulation requirement per local code, including tapered insulation and crickets for positive drainage

• type of high-density coverboards

• type of roofing membrane

• length of the warranty term and any required enhancements.

Conduct a pre-bid meeting:

• Discuss work hours, building access and other site regulations or concerns.

• Identify the laydown area for materials and the area for crane staging.

• Determine whether overhead protection is required.

Perform a proposal review:

• Quantify the proposals and identify red flags.

• Request a letter from the manufacturer supporting the contractor, a manufacturer’s letter of intent to warrant the project, and the manufacturer’s sample warranty.

• Ask for the contractor’s certificate of insurance and references for similar projects.

• Conduct interviews with contractors under consideration to discuss their proposals, approach, manufacturer’s involvement and warranty.
