Roof Inspections and Certifications
A roof inspection describes what is visible and serviceable today. A roof certification goes one step further: after inspection and any required repairs, the contractor provides a written, limited statement about the roof's ability to protect the building for a defined period under stated conditions.
Drennen Custom Contracting performs roof-condition inspections, repair evaluations, real-estate inspections, maintenance planning, storm assessments, and limited certifications throughout Fort Collins and Northern Colorado.
An inspection, report, and certification are not the same service. Ask exactly what document will be provided, what repairs are required, how long any certification lasts, and what conditions are excluded.
Inspection, Report, and Certification: What Is the Difference?
Roof inspection
A visual and, when accessible, attic-based evaluation of the roof's current condition. The inspector identifies observed defects, maintenance items, damage, approximate age indicators, ventilation concerns, and repairability.
Written roof-condition report
A document that summarizes the inspection findings, photographs, repair recommendations, and limitations. It may be used for maintenance planning, a real-estate transaction, or communication with an insurer or property manager.
Roof certification
A separate written document issued only when Drennen believes the roof meets the stated certification criteria. Repairs may be required first. The certification has a defined term, scope, conditions, and exclusions.
When a Roof Inspection Is Useful
- Buying or selling a home.
- Responding to an insurance underwriting request.
- Evaluating a roof before listing a property.
- Planning repairs or replacement before a budget deadline.
- Investigating leaks, odors, condensation, or ceiling stains.
- Checking a roof after hail, wind, or heavy snow.
- Establishing a maintenance plan for a rental or managed property.
- Verifying work performed by another contractor.
- Preparing for solar installation, remodeling, or a change in rooftop equipment.
What Drennen Evaluates
The inspection is tailored to the roof type, access, purpose, and weather. Typical items include:
Roof covering
Shingle age indicators, granule condition, cracking, curling, blistering, exposed fiberglass, seal condition, repairs, missing shingles, wind creases, impact marks, and surface contamination.
Flashing and water-management details
Sidewalls, headwalls, chimneys, valleys, dormers, kickouts, roof-to-wall transitions, low-slope tie-ins, counterflashing, and vulnerable changes in roof direction.
Penetrations and accessories
Pipe jacks, bath and kitchen vents, combustion vents, skylights, evaporative coolers, solar mounts, satellite attachments, roof hatches, gutters, and fasteners.
Decking and structure
Visible sagging, soft areas, moisture staining, delamination, spaced sheathing, prior repairs, and accessible framing conditions. A non-invasive inspection cannot reveal every concealed defect.
Attic ventilation and exhaust ducts
Intake and exhaust type, estimated net-free area, blocked soffits, mixed exhaust systems, insulation interference, condensation, mold indicators, and bathroom or kitchen ducts that do not terminate outdoors.
Drainage and adjacent construction
Gutter slope, downspouts, roof runoff against siding, fascia and soffit deterioration, wall cladding, sealants, and locations where water can bypass the roof covering.
How the Certification Process Works
- 1
1. Define the purpose.
Is the document for a buyer, seller, insurer, lender, property manager, or the homeowner's own planning? The recipient may have specific forms or minimum terms.
- 2
2. Inspect the roof and accessible attic.
Drennen documents visible conditions, repairability, ventilation, and potential limitations.
- 3
3. Identify required repairs.
A roof is not certified merely because a fee was paid. Missing shingles, failed flashings, exposed fasteners, defective penetrations, ventilation issues, or other concerns may need correction.
- 4
4. Complete and verify the work.
After repairs, Drennen reinspects the relevant conditions and confirms that the roof meets the written certification criteria.
- 5
5. Issue the certification.
The document identifies the property, inspection date, certification term, conditions, exclusions, responsible company representative, and any maintenance requirements.
How Long Is a Roof Certification?
Drennen's certification term depends on the roof's material, age, condition, repair scope, and intended use. Limited terms such as two or five years may be appropriate for a serviceable existing roof. A certification is not automatically available for every roof, and a longer term is not promised merely because a homeowner requests one.
The written certification should distinguish between:
- The inspector's opinion of remaining serviceability.
- The actual period covered by the certification.
- The repairs that had to be completed before issuance.
- Events and conditions excluded from the certification.
An Example From Loveland
In a 2026 Loveland inspection, Drennen found that the roof could potentially remain serviceable, but several conditions required correction before a certification could be issued. The repair list included replacing power attic vents with a coordinated ridge-exhaust approach, adding intake ventilation, rebuilding chimney waterproofing and counterflashing, correcting a roof-to-wall transition, improving gutter drainage, repairing water-affected soffit, coating roof metal, and replacing deteriorated pipe-jack neoprene as needed.
After the listed work, Drennen's written opinion estimated at least ten years of serviceable life and offered a five-year limited certification. This example illustrates why a certification is based on the complete roof condition, not only the age of the shingles.
This is an anonymized example, not a promise that another roof will qualify for the same term or service-life opinion.
What a Certification Cannot Guarantee
A limited roof certification cannot:
- Prevent hail, wind, falling-tree, wildfire, or other future damage.
- Guarantee that an insurer, lender, buyer, or inspector will accept the roof.
- Cover defects that were concealed and not reasonably visible during the inspection.
- Reverse widespread aging, granule loss, brittleness, or material deterioration.
- Cover alterations or damage caused by another contractor, resident, animal, or rooftop equipment.
- Guarantee interior finishes, plumbing, HVAC, windows, walls, or unrelated building components.
- Replace the terms of a homeowners insurance policy or manufacturer warranty.
Roof Certifications and Insurance Underwriting
Some insurers consider a professional inspection or certification when evaluating an older roof. Others make decisions primarily from age, material, aerial imagery, claim history, or company underwriting rules. A certification that satisfies one carrier may not satisfy another.
Before paying for extensive repairs solely to obtain insurance, ask the agent in writing:
- Will this carrier accept a contractor's roof certification?
- What minimum certification term or form is required?
- Will acceptance change roof coverage from actual cash value to replacement cost?
- Will the wind-and-hail deductible change?
- Will the carrier still require replacement based on age or material?
- How long will the carrier honor the documentation?
A certification may support underwriting, but the insurer alone decides eligibility, coverage, deductible, premium, and policy terms.
Real-Estate Roof Inspections
A real-estate roof inspection should be clear enough for a buyer and seller to understand without turning every maintenance item into a crisis. Drennen separates observed conditions into practical categories:
Immediate repair
Conditions that are actively leaking, unsafe, open to weather, or likely to cause near-term damage.
Repair before certification
Items that must be corrected before Drennen can issue the requested limited certification.
Maintenance or monitoring
Conditions that do not presently require major work but should be serviced, documented, or watched.
Replacement planning
Widespread age or deterioration that makes ongoing repair financially inefficient.
Drennen has no financial interest in whether a property transaction closes. The goal is a factual construction opinion and a practical scope.
Questions to Ask Before Ordering a Certification
- Does the receiving party require a specific form?
- Is an attic inspection included?
- Will photographs and a repair estimate be provided?
- Is the inspection fee credited toward approved repairs?
- What happens if the roof does not qualify?
- Who is responsible for maintenance during the certification term?
- How are storm damage, ice dams, condensation, and third-party work handled?
- Is the certification transferable to a buyer?
- What notice must be given if a leak occurs?
Frequently Asked Questions
Get the Right Document for the Decision
Tell Drennen why the roof is being evaluated and who needs the result. We will explain whether you need a basic inspection, written report, repair estimate, or limited certification - and what must happen before the document can be issued.
Inspections are limited to visible and accessible conditions on the inspection date. Certifications are governed exclusively by their written terms and exclusions. They do not guarantee insurance eligibility, future weather performance, or concealed conditions.
