Repair or Replace? Budgeting Ahead for a Commercial Roof Replacement

Every flat roof eventually reaches the point where another patch is a poor answer. The hard part is knowing when you're there, and when the money needs to be in the plan. Facility managers and school business officials who handle this well rarely have a magic number. They have records, a roofer who knows the building, and enough lead time to make the decision on their own schedule rather than the weather's.

Signs that repair has stopped being enough

A repair solves a specific problem. Replacement addresses a roof whose problems are systemic. Watch for these patterns:

• The same areas leaking again after repairs, or new leaks appearing next to old patches
• Wet insulation under the membrane, which a repair to the surface can't dry out
• Seams opening across the roof instead of in one corner
• Flashings that have shrunk, split or pulled loose at many locations
• Membrane that is brittle, cracked or visibly worn down in traffic areas
• Repair invoices that keep growing from one year to the next

One or two of these doesn't force a decision. A cluster does, and it's your cue to ask for a full evaluation rather than another call-out.

Let the records make the case

This is where maintenance documentation pays off. A&M Roofing Services' maintenance packages include written reports, photo documentation and a roof plan, along with budgeting for major repairs or replacement when it becomes necessary. With a year or two of those reports, you can show a board, an owner or a finance director exactly which areas are failing, how quickly, and what has gone into patches. That's far more persuasive than a statement that the roof is old.

If you don't have records yet, start now. Even one thorough inspection with photos and a marked-up roof plan gives you a baseline, and every later visit adds to the trend line.

What a replacement scope involves

Replacement scope varies widely, so insist on specifics in writing. Find out whether the old membrane comes off or the new one goes over it, what happens to the insulation, how flashings, edge metal and drains will be handled, and which manufacturer system is specified. Whether a recover over the existing roof is possible depends on the condition of what's underneath and on local requirements, so ask the roofer to explain what they found and why they recommend one approach over another.

A&M specializes in single-ply membrane and can also install built-up, steep slope and architectural metal roofs. The company is licensed by Carlisle, Sika-Sarnafil, Firestone, Johns Manville and Duro-Last, so you can ask about more than one system for the same building. Installations are built to meet or exceed manufacturer specifications and are covered by warranty.

Planning the money and the timing

Roof replacement is a capital expense, and the pain comes from surprise. Put the roof on your multi-year plan as soon as the evidence points that way, even if the work is a year or more out. A scheduled replacement lets you gather proposals, compare systems and pick a window. Schools often favor summer break, retail wants to stay clear of the holiday season, and manufacturing plants have to work around production.

For large buildings, ask about phasing. Replacing the roof in sections over more than one budget cycle can spread the cost and keep the building running. Phasing has tradeoffs, since the transitions between old and new areas need careful detailing, so talk it through with the contractor before committing.

Getting proposals you can compare

Two proposals can look similar and describe different roofs. Put the same questions to every bidder:

• What membrane type, thickness and attachment method are included?
• What is covered for insulation, tapered systems and drainage?
• Who does the work, the contractor's own crews or subcontractors?
• Which manufacturer warranty options apply, and who is licensed to offer them?
• How will the crew protect the building interior and the people in it during the work?

Free estimates make it easy to collect this information. A&M has worked on everything from elementary schools and neighborhood retail strips to high-tech manufacturing and medical care environments, so occupied buildings with sensitive operations aren't new ground.

Start the conversation early

The best time to ask for a replacement estimate is before you need one. An early look gives you options, and a roof that is only beginning to fail can often be managed with repairs while you plan. A late look, during an emergency, leaves you buying whatever can be scheduled soonest.
