Commercial Roofing FAQs
What if you come out and perform a repair but it’s not fixed?
We fix leaks 97% of the time. However, 80% of leak sources are invisible to the naked eye. Some issues are hidden or part of a failing roof system. We’ll always do what’s right and keep your costs low.
How much does a repair cost?
Repairs are billed by time and materials.
- Standard rate: $100/hour per tech (usually 2 techs)
- Emergency rate: $200/hour per tech (within 4 hours, after-hours/weekends)
- Travel fees:
- 0–30 miles from Pella: $300
- 31–75 miles: $400
- 76+ miles: $500
Materials: Charged as incurred.
How long does a commercial roof repair take?
It depends on the roof type, damage, and size. Weather, roof access, and material type can also affect timing.
Typical timelines:
- Small patch (TPO, EPDM, PVC): 2–4 hours
- Sealant/flashing: 1 day
- Leak + minor fix: 1 day
- Vents/drains/curbs: 1–2 days
- Moderate repairs: 2–4 days
- Major repairs: 1+ week
How long will roof repairs last?
Lifespan depends on the type of repair and quality of work:
- Sealant or small patch: 1–5 years
- Flashing or vent boot replacement: 5–10 years
- Membrane patch (TPO, EPDM, PVC): 5–15 years
- Partial re-roof or large section: 10–20+ years
Proper installation and maintenance can extend these timelines.
When should I replace my commercial roof?
Replace your commercial roof when:
- Leaks keep returning despite repairs
- Damage is widespread or structural
- The roof is nearing its lifespan (15–30 years for flat roofs, up to 50 for metal)
- Energy bills spike from poor insulation
- Interior mold appears due to hidden water intrusion
A full replacement may cost more upfront but saves you from repeat repair costs and ongoing damage.
How do I know if my commercial roof needs repair?
Leaks, stains, ponding water, cracks, or loose flashing are red flags. Annual inspections help catch problems early.
Can I just patch the leak, or do I need a full replacement?
If the roof is in good shape and damage is isolated, a patch works. Widespread issues may require full replacement.
How much do repairs cost?
Minor fixes start at a few hundred dollars. Major or structural repairs can cost thousands.
How long will the repair take?
Anywhere from a few hours to a week, depending on scope, weather, and materials.
Will my business be disrupted?
Usually not. We work to minimize impact, though some areas may be briefly restricted for safety.
Are repairs covered by warranty?
Yes. Many come with a 1–5 year workmanship warranty and 5–20+ year manufacturer warranties.
Can you repair a roof in bad weather?
Some repairs, yes. But certain materials need dry, warm conditions to cure properly.
How long will the repair last?
5–15 years depending on the type of repair, material, and maintenance.
What maintenance is needed after a repair?
Inspect regularly, clean drains, and check repairs after storms to prevent future issues.
What if I have an emergency leak?
Protect valuables, contain the leak, and call for emergency service right away. Document damage.
