Roofing Procurement Support - RFP Drafting, Bid Evaluation

Supporting Denver commercial owner procurement teams with RFP drafting, bid evaluation, contractor reference checking, and scope equivalency review on commercial roofing projects - including CRS 24-103 compliance for public owners.

We work alongside Denver owner procurement teams - writing RFPs, evaluating bids for scope equivalency, and reference-checking contractors the owner does not know - on roofing projects where we are not in the bid pool.

Large institutional owners, REITs, and Denver building owners with formal procurement policies often need roofing expertise on the owner's side of the procurement table - not as a bidder, but as a technical resource that helps the procurement team ask the right questions and evaluate answers without being sold to.

We offer procurement support engagements where we are explicitly removed from the contractor bid pool. The arrangement is straightforward: you retain us to help draft the RFP, evaluate bids, and check contractor references. We do not submit a competing bid on the same project. Our role is technical advisory - writing scope language that produces comparable bids, building the evaluation matrix, and flagging scope exceptions that shift apparent cost comparisons.

The Denver commercial roofing market is opaque enough that most procurement teams have meaningful gaps in contractor evaluation. Which Front Range contractors have closed out manufacturer NDL warranties on large Colorado projects with Class 4 impact-rated systems in the last five years? Which ones have had warranty-inspection failures in Denver's freeze-thaw environment and how did they resolve them? Which ones have the crew capacity and altitude-specific application experience to execute a 200,000 sq ft replacement at 5,280 feet without subcontracting the skilled membrane work? We know the answers and can share them honestly when we are not competing for the work.

A commercial roofing RFP that produces useful bids in the Denver market must specify at minimum: building dimensions and access constraints (roof area, number of levels, parapet heights, crane access, elevator or hoist capacity for material staging at altitude), existing roof system documentation (membrane type, approximate age, insulation type, warranty status, any prior hail-event assessments), scope boundaries (what is in scope and what is not), performance requirements (wind-uplift rating against the applicable ASCE 7-22 exposure category, minimum insulation R-value to IECC 2021 Climate Zone 5 minimums, warranty term and type, impact-resistance class - FM 4470 Class 1 or UL 2218 Class 4), closeout documentation requirements including impact-resistance certification, and insurance and bonding requirements.

The bid form should force all bidders to break out labor, material, cover board, permit, warranty premium, impact-resistance certification, and closeout costs as separate line items. Lump-sum bids on Denver commercial roofing projects are not comparable - they are different contractors' decisions about which line items to make visible and which to absorb into a number the owner cannot decompose.

For Colorado public owners - state agencies, county governments, and other entities subject to CRS 24-103 - the RFP must also address bidder qualification requirements, the competitive solicitation method (invitation for bid vs. request for proposals), documentation of scope equivalency for the bid record, and the bid protest procedures the statute requires. We draft RFPs that satisfy both the technical specification requirements and the procurement compliance requirements of Colorado public contracting law.

Bid Evaluation - Reading What the Denver Bids Say

When bids come back, the first pass is scope equivalency: did all bidders price the same scope? In Denver commercial roofing, the most common scope deviation is cover board omission - a bidder who prices standard-density polyiso where the RFP specified HD cover board for Class 4 qualification is delivering a meaningfully different product at a lower cost. We find this deviation on roughly one in three Denver commercial bids we evaluate. We produce a scope-equivalency table before the procurement team compares numbers.

The second pass is unbalanced bid analysis: are any line items priced in a way that suggests a strategy to recover margin through change orders? Low base-work bids paired with above-market unit prices on allowance items - insulation replacement, deck replacement, drain replacement - are the most common pattern in Denver commercial bids. We flag these. The third pass is qualifications review: does the bidder have the insurance limits, manufacturer credentials, altitude-specific installation experience, and documented project history the RFP specified? Bids from contractors who do not

We conduct structured reference checks on contractors in the bid pool that the owner has not worked with before. The questions are specific: what are the last three completed Colorado commercial projects over $300,000? Can you provide manufacturer warranty closeout documentation from each? Who was the manufacturer field representative who did the final warranty inspection? Did the NDL warranty issue as specified and has it remained active?
