Four hundred dollars in March. Four hundred dollars again in July. Four hundred dollars the following spring, after a wind night pulled the same valley open. By the third invoice, a small landlord in West Jordan usually stops calling a handyman and starts pricing the roofing companies West Jordan UT owners hire for a full tear-off. The argument is plain: on a twenty two year old roof over a rental duplex, replacing it costs less across five years than the patching it prevents, and it turns an open ended repair drip into one dated capital cost you can budget against. That makes it a money question before it is a construction question.
Patching A Twenty Two Year Old Roof Buys Months
A patch is a legitimate repair, and on a ten year old roof it is almost always the right call. Past twenty, it is a payment plan with no end date on it. What we usually find on older rentals is that the shingle field has lost its granules and gone brittle, so the sealant strip no longer grabs the course below it, and the next storm lifts a section three feet from the one that was just repaired. Nail heads back out. The valley metal is often fine; the shingles running into it are not.
An owner working from a four hundred dollar monthly maintenance reserve feels that pattern faster than a portfolio owner does, because there is nowhere to spread the hit. One patch call eats the month. Two of them eat the appliance money (the water heater does not care that the roof went first). By the second year the reserve exists mostly on paper, and every unplanned expense on the property is competing with shingles.
The Five Year Math On One Duplex
Run the patch path first, because it is the one that hides. Say the duplex takes two service calls a year at $400 each, which is $800 a year and $4,000 across five years. Add one drywall and paint repair at $700 the winter a leak finally reaches a bedroom ceiling, plus a month of vacancy at $1,150 when the tenant on that side decides not to renew. Five years of patching comes to $5,850, and the roof at the end of it is twenty seven years old and worth nothing to an appraiser.
Now the replacement side, and treat this figure as an illustration rather than a quote, since the only number that matters is the one on your own bid: say a tear-off and asphalt reroof on a duplex that size lands at $13,500. Most roofing companies West Jordan UT landlords gather bids from will break that total into four lines, tear-off and disposal, underlayment and flashing, the shingles themselves, and labor. Two of those lines are close to fixed by the building itself, which is why a $2,000 spread between two bids usually traces back to disposal and crew size rather than to better shingles. Spread $13,500 across the service life of a new asphalt roof and it prices out near $45 a month, set against a reserve that was already losing $800 a year to repairs that fix nothing permanent.
Replace Between Tenants Not During A Leak
The date on the calendar moves the real cost more than most owners expect. A roof replaced inside a vacancy window, and August is the common one for a duplex on a school year lease cycle, costs the same in materials but far less in everything around them: no tenant to work around, and no rent credit for a week of hammering overhead. Emergency work never gets that discount. A February leak buys you a tarp, a crew booked at whatever rate a crew happens to be available for, and interior repairs that would not exist if the same money had gone out in the summer. Before signing anything, run the contractor’s license number through Utah’s DOPL license lookup, which is free and takes about a minute, then ask for the labor warranty in writing alongside the manufacturer’s shingle coverage. A written labor warranty is what turns the job from a purchase into a covered asset, and without one you are back to calling somebody every spring.
The payback question is easier to accept once somebody has run it at scale rather than on one property. Remodeling magazine’s cost versus value reporting on replacement projects is the work I keep returning to, and it points to a rental roof replacement breaking even in 5 to 7 years once the avoided patch calls and avoided interior repairs are counted against it. I sat down with those numbers in June 2026, mid vacancy, with a bid already on the kitchen table. Five to seven years sits comfortably inside how long most single property owners actually hold a duplex.
None of this makes the check easier to write. It makes the number knowable, which the patch path never does. Two service calls a year has no final invoice attached to it, while a replacement scheduled into a vacancy window has a date, a price, a warranty and a service life you can amortize against rent. The reserve account tells you before the ceiling does. If the roof over your rental is past twenty and the patch calls have started clustering, price the full replacement this season and put the crew in the August window instead of finding out what February costs.
