Garage and Outbuilding Roofs
A detached garage roof is a small, simple version of a house roof — usually a single gable, no penetrations to speak of, low pitch, and easy ladder access. Most are 4 to 9 squares and finish in a single day.
- Asphalt shingle is the usual choice, and matching the house roof matters if the garage is visible from the street or governed by an HOA
- Exposed-fastener metal panel is a legitimate and often cheaper option on a detached shop or barn, at $7 to $12 per square foot
- Older detached garages frequently have plank decking rather than plywood, which occasionally needs sheathing over before shingles can go on
- If the garage roof ties into the house roof, the transition flashing is the part that matters and it is worth doing both at once
- Attached garages are almost always done as part of the main roof, and pricing them separately rarely saves anything

What Actually Happens on the Job
Here is the full sequence for a typical the Salt Lake Valley project, so nothing on the day is a surprise.
- 1
Free inspection
We get on the roof, photograph what we find, and check the attic where access allows. Ventilation and decking condition get looked at, not assumed.
- 2
Written estimate
You get an itemized scope, a material selection, a price, and a plain-language explanation of anything we flagged. No same-day-signature discount, ever.
- 3
Scheduling and materials
We book the date, order material, and pull the permit. Material is usually delivered the day before or the morning of.
- 4
Protection and tear-off
Landscaping, AC units, and driveways get covered. The old roof comes off down to the deck. On most homes this is the loudest three hours of the project.
- 5
Deck inspection
With the roof off, we walk every square foot of decking. Soft or rotted sheets are replaced and counted, and you see the count before we cover it up.
- 6
Dry-in
Ice-and-water shield at eaves, valleys, and penetrations. Synthetic underlayment across the field. The house is weather-tight from this point forward.
- 7
Flashing and ventilation
New flashing at walls, chimneys, and penetrations. Ridge vent cut and installed, intake ventilation verified.
- 8
Shingles, ridge, and cleanup
Field shingles, then hip and ridge cap. Magnet sweep of the yard and driveway, debris hauled off the same day.
- 9
Final walkthrough
We walk it with you, hand over the warranty paperwork, and the final payment is due after you have seen the finished job — not before.
Garage Roof Replacement FAQs — the Salt Lake Valley
Are you licensed and insured in Utah?
Yes. Utah DOPL license #13872603-5509, and we carry both general liability and workers' compensation. Look the license number up yourself, and ask us to have our agent send the certificate of insurance to you directly — that is what you should require of any contractor bidding your roof.
How soon can you come out?
Usually within a few days for an estimate, and same-day for an active leak where we can safely get on the roof. Call 385-534-3402 and we will tell you honestly what the schedule looks like rather than promising a slot we do not have.
Is the estimate really free?
Yes, and it is written and itemized. There is no charge, no obligation, and no expiring discount. If your roof does not need work, we will tell you that and leave.
How much is a garage roof?
A two-car detached garage typically runs $2,600 to $5,800 in asphalt shingle, and a single-car $1,800 to $3,800. Most are a single day on site.
Should I match my house roof?
If the garage is visible from the street or you are in an HOA, yes. If it is a shop behind a fence, an exposed-fastener metal panel is often cheaper and lasts longer.
Can I do the garage now and the house later?
Absolutely, and it is a common way to spread cost. The one exception is where the garage roof ties into the house roof — that transition flashing is best done once, with both.
