Every commercial roof warranty sold in Iowa - TPO, PVC, EPDM, modified bitumen - carries a maintenance condition. Somewhere in the document, the manufacturer states that coverage depends on periodic inspections by a qualified contractor, documented and kept on file. Most Des Moines owners read that paragraph for the first time on the day they file a claim. By then it is either an asset or a hole in the coverage, and there is no third option.
A roof service agreement is the simplest way to keep that paragraph working for you instead of against you.
What the Manufacturers Actually Require
GAF, Carlisle, Firestone, Johns Manville, and the other major brands write their warranties on the assumption that someone qualified is on the roof at least annually - most expect semi-annual - and that every visit produces a dated record. Miss the cadence and the manufacturer does not send a warning letter; the gap simply sits in the file until a claim arrives, and then the field representative asks for the maintenance history before anything else. No history, weak claim. It is the least dramatic way to lose six figures of coverage.
How the Agreement Keeps Coverage Intact
Our service agreement puts two scheduled rooftop service visits per year on the calendar - the exact cadence the warranty language anticipates. Each visit is recorded the way a manufacturer wants to see it: dated photos, deficiencies noted with locations, corrections logged. The work itself matters just as much. Drains get cleared, seams and flashings get checked and resealed, and small membrane defects get repaired while they are still small, because neglect-related damage is the first thing every warranty excludes.
And because central Iowa winters are hard on membranes, every agreement adds a pre-snow visit before winter sets in: drains and scuppers cleared so meltwater has somewhere to go, membrane and flashings checked before months of snow load and freeze-thaw cycling. A January failure traced to a drain nobody cleared is exactly the kind of claim a manufacturer denies - the pre-snow record closes that door.
When the Claim Comes
If a covered failure does occur, the agreement file becomes the spine of the claim: proof of maintenance at the required intervals, photographs establishing the roof's condition before the failure, and a contractor who already knows the roof standing by to execute whatever the manufacturer approves. Claims with that file behind them tend to move in weeks. Claims without it turn into arguments.
What to have ready for an agreement quote
Send the roof address, membrane type and age if known, a copy of the warranty or the installing contractor's name, access instructions, and any leak history. We confirm the warranty's inspection requirement during the baseline walk and set the visit calendar to match it.
Warranty and Agreement Questions
Will these visits satisfy my manufacturer's inspection requirement?
Yes. The visit cadence, the report format, and the record-keeping are matched to what the major manufacturers require. If your specific warranty calls for something beyond that - some premium programs do - we fold it into the schedule.
We have not documented maintenance in years. Is the warranty already lost?
Not necessarily. Coverage disputes weigh the condition of the roof and the record from here forward as much as the gap behind you. The right move is to start the file now: a baseline walk, correction of anything neglect-related, and a clean cadence from this season on.
Do you help with the warranty claim itself?
We prepare what the claim depends on - the maintenance history, dated photos, and a condition report for the failure - and we meet the manufacturer's field inspector on the roof. The claim is filed in the owner's name, but you will not be working it alone.
Our roof has no active warranty. Is an agreement still worth it?
Yes. The same visits that satisfy a warranty are what stretch the life of an uncovered roof. And when you re-roof later, arriving with a documented maintenance habit makes the next warranty easier to register and defend.
