Overview
Replacement means removing old roofing and installing new underlayment and shingles or other material.
Most homes take one to a few days.
What the work usually involves
- Tear-off. Old roof removed.
- Install. Underlayment, flashing and shingles.
- Materials are delivered. Expect a delivery and a dumpster or trailer in the driveway.
- A final walk-through follows. Check flashing, vents and cleanup before you sign off.
- Describe the roof and the problem. Age, material and where you see leaks or damage help a lot.
- Expect a roof inspection. Roofers check shingles, flashing, vents and decking.
- Permits are common for replacements. Many cities require a permit to re-roof.
Before you decide
- Hail is a big factor in Colorado. Hail damage can be hard to see from the ground.
- Weather affects scheduling. Wind, rain and cold can push installation dates.
- Material options. Asphalt, metal and more.
- Impact-resistant shingles. May reduce insurance in hail areas.
- Ventilation affects roof life. Poor attic ventilation can shorten shingle life.
- Underlayment and flashing matter. They often decide whether a roof leaks, not just the shingles.
Before you send an inquiry
- Rough measurements or quantities, if they matter for the job.
- Your address or nearest cross streets so the request reaches someone local.
- Your timeline, and whether anything is urgent.
- A short description of the job and where it is on the property.
- Any HOA, landlord or property manager rules that apply.
Warning signs
- No written estimate, or an estimate with vague scope.
- Door-to-door offers right after a storm with no local track record.
- Unwilling to share proof of insurance or a license where one is required.
- Requests for large cash deposits before any work is scheduled.
- Pressure to sign or pay the same day.
What to ask before you commit
- Will you replace damaged decking, and how is it priced?
- Can you provide a written, itemized estimate?
- How will you protect landscaping and clean up nails?
- Will you pull the permit for a replacement?
- What does the warranty cover, and is it from you or the manufacturer?
- Are you licensed and insured where required?
Quick answers
- How long does replacement take?
- Often one to three days for a typical home.
- Can new shingles go over old?
- Sometimes allowed, but tear-off is often recommended.
- Should I repair or replace my roof?
