The process
How a roofing project works, start to finish
Eleven stages, what happens at each, and where jobs usually go wrong.
Last updated .
The short version
- Eleven stages, from the problem being identified to the warranty documents being handed over.
- The tear-off and installation on a typical house takes days. Scheduling, permits and material lead times take longer.
- Deck damage found after tear-off is the usual reason a job runs past its quote. Agree the per-sheet rate before the roof is opened.
- Agree in writing who authorises extra work mid-job, and up to what amount.
- Do the final walkthrough before the final payment.
This is about the job, not about us. HyreRoof does not perform or supervise roofing work, this page describes what a roofing project typically involves so you recognise it when you are in one. For how our platform works, see how HyreRoof works.
The decision sequence, before any of it starts
Five steps, in the order that keeps you in control of the project.
01. Get the roof inspected
Independently where you can. Establish age, layers, deck condition and where water is actually getting in.
02. Decide repair or replace
Weigh the repair against remaining service life. Write down which one you are buying before you take bids.
03. Fix the scope
Decide covering, underlayment, ice barrier, flashing and ventilation. Hand the same scope to every bidder.
04. Compare three written quotes
Squares, tear-off, deck rate, accessories, warranties and permit responsibility: line by line, not price to price.
05. Set the terms and schedule
Payment stages, lien waivers, weather contingency, cleanup and both warranty documents before the first bundle is loaded.
The project timeline
Once you have chosen a company, this is roughly how the job runs. Sequences vary by company, material and jurisdiction, a tile re-roof in a permit-heavy city looks nothing like an asphalt tear-off in a rural one.
| # | Stage | What happens |
|---|---|---|
| 01 | Problem identified | A leak, storm damage, an ageing covering or a sale. What you have noticed shapes the whole job, so write it down before anyone arrives. |
| 02 | Professional contacted | Ideally more than one, and ideally before the situation is urgent. Scheduling is the longest part of most roofing projects. |
| 03 | Roof evaluated | On the roof and in the attic. Ground-level photographs find missing shingles; they do not find a wet deck or failed step flashing. |
| 04 | Scope developed | What is being removed, what is going back on, which flashing is replaced, what ventilation you end up with. This is the document everything else depends on. |
| 05 | Estimate prepared | Squares, tear-off, deck repair rate, accessories, permit, warranties. Itemised, not a single figure. |
| 06 | Options reviewed | Material, grade, colour, upgrades. Ask which upgrades change performance and which only change appearance. |
| 07 | Contract signed | Scope, price, payment stages, lien waivers, weather contingency, cleanup, start window and who authorises extra work up to what amount. |
| 08 | Materials scheduled | Delivery and staging. Lead times on anything other than common asphalt can run long. |
| 09 | Work performed | Tear-off, deck inspection and repair, underlayment and ice barrier, flashing, covering, ridge and ventilation. Deck damage found here is the usual reason a job runs longer than quoted. |
| 10 | Final walkthrough | Magnet sweep for nails, gutters cleared, landscaping checked, and a look at the finished flashing details and ridge from the ground. |
| 11 | Warranty and documentation | Both warranty documents, the permit sign-off and the final invoice. Keep them: the next buyer of the house will ask. |
Where projects usually go wrong
- The deck. Nobody knows its condition until the covering is off, so agree the per-sheet rate before the roof is opened.
- Reused flashing. Putting a new covering over old flashing is a false economy you will meet again at the next leak.
- Ventilation left as found. A new roof over a badly ventilated attic ages early. Ask what intake and exhaust you will be left with.
- Verbal change orders. Anything that changes the price should change the paperwork.
- Final payment before the walkthrough. Do the walkthrough first.
Common questions
How long does a roof replacement take?
The tear-off and installation on a typical single-family home is usually a matter of days, weather permitting. The longer part is everything around it: getting on the schedule, the permit, material lead times and the inspection afterwards. Deck damage found after tear-off is the most common reason a job runs longer than quoted.
Do I need to be home during roofing work?
Not usually, but someone should be reachable. Deck damage, unexpected flashing conditions and weather decisions all come up mid-job and need an answer. Agree in advance who authorises additional work and up to what amount, in writing.
What happens if it rains during my roof replacement?
Crews work in sections and dry the roof in at the end of each day, so an open deck is not usually left overnight. Your contract should say what happens if weather opens the roof mid-job and who carries the cost of resulting damage, ask before you sign, not after.
What should happen at the end of a roofing job?
A magnet sweep of the grounds and driveway for nails, gutters cleared of debris and granules, landscaping and driveway checked, all waste removed, the permit signed off, and both warranty documents handed over. Walk it with the crew lead before the final payment.
