Restore or Replace?

Not Every Aging Roof Needs to Be Replaced

When the existing roof and substrate are suitable, a properly prepared and applied roof coating system may be an option for restoring and protecting the existing roof, rather than tearing it off and starting over.

The key word is suitable. WW evaluates the roof first, identifies the problem areas and recommends coating only when the existing conditions make it appropriate. If they don't, we'll tell you and explain the other options, from targeted roof repair to spray foam roofing or replacement.

01

Evaluate First

Every coating recommendation starts with an inspection of the existing roof, not a product pitch.

02

Coat Only When Appropriate

Coating is recommended when the roof and substrate are suitable candidates after corrective repairs.

03

Straight Answers

If repair, spray foam, reroofing or replacement makes more sense, that's what we'll recommend.

Commercial Roof Coating Systems

Coating Work Starts With the Existing Roof

Before any coating is applied, WW evaluates the existing roof condition, the substrate, drainage, seams, flashings, penetrations and existing problem areas. Not every roof can be coated, and a coating is only as good as the roof and preparation underneath it.

01

Commercial Roof Restoration

Restoring a suitable existing roof with corrective repairs and a coating system instead of immediate replacement.

02

Existing Roof Coating & Recoating

Coating an existing roof, or recoating over a previous coating or an existing spray foam roof after its condition and adhesion are evaluated.

03

Metal Roof Coating

Coating systems for commercial metal roofs after fasteners, seams, laps and rust areas are addressed.

04

Seam & Fastener Preparation

Treating seams, laps and exposed fasteners so they're sealed and ready for the coating system.

05

Flashing & Penetration Preparation

Detailing flashings, curbs, pipes and rooftop penetrations, where many roof leaks begin.

06

Repairs Before Coating

Correcting damaged, wet or failed areas before coating, so problems aren't simply covered over.

07

Protective Coating Application

Applying the selected coating system according to the requirements of that system.

08

Ongoing Inspection & Maintenance

Follow-up inspections and maintenance to keep an eye on the coated roof over time.

Inspection comes first. WW doesn't assume every roof is a coating candidate. We look at the whole roof, document what we find and explain whether coating, repair or another approach fits your building.

Restore a Suitable Roof Instead of Replacing It

Some commercial roofs can be restored rather than immediately replaced, when the existing system is a suitable candidate. Whether a roof qualifies depends on what's going on underneath the surface, so WW evaluates these conditions before recommending anything:

  • Existing roof condition
  • Moisture or wet insulation
  • Substrate condition
  • Drainage
  • Existing leaks
  • Flashings
  • Seams
  • Penetrations
  • Previous coatings
  • Required repairs & preparation
We inspect before we recommend. WW inspects the roof before recommending any coating system. A coating applied over wet insulation, a deteriorated substrate or unresolved leaks won't fix those problems.
Commercial Metal Roof Restoration

Metal Roof Coating & Restoration: The Details Matter

Commercial metal roofs move with heat and cold, and the weak points are usually the details: fasteners, seams, laps and transitions. Preparation and corrective repairs are important before any coating is applied, because a coating won't stay sealed over loose fasteners, open laps or active corrosion.

When WW evaluates a metal roof for restoration, we look at:

  • Exposed fasteners
  • Seams
  • Laps
  • Flashings
  • Penetrations
  • Curbs
  • Roof edges
  • Rust & corrosion areas
  • Previous repairs
  • Existing coating condition
  • Drainage

When a Roof Should Not Just Be Coated

A Coating Is Not a Substitute for Fixing Serious Problems

A roof coating protects the surface of a roof that's in suitable condition. It does not correct serious underlying problems. When the inspection finds conditions like these, additional repair or a different roofing approach may be needed.

01

Saturated or Damaged Materials

Wet insulation or damaged roofing materials that need to be removed and replaced, not covered.

02

Significant Substrate Deterioration

A roof deck or substrate that has deteriorated to the point that a coating can't be properly supported.

03

Structural Concerns

Sagging, deflection or other structural issues that need to be evaluated and addressed first.

04

Extensive Trapped Moisture

Large areas of moisture trapped within the roof system that would remain sealed in under a coating.

05

Severe Drainage Problems

Significant ponding or drainage issues that need to be corrected rather than coated over.

06

Failed Areas Requiring Removal

Sections of the roof that have failed and require removal or replacement before anything else.

Find Out If Your Roof Is a Coating Candidate

Request a commercial property assessment and WW will evaluate the existing roof before recommending a coating, repair or another roofing solution.

Our Process

Our Commercial Roof Coating Process

Every coating project follows the same process, so you know what we found, why we're recommending it and what happens next.

STEP 01

INSPECT

Evaluate the existing roof and identify problem areas.

STEP 02

DOCUMENT

Photograph and document roof conditions.

STEP 03

DETERMINE SUITABILITY

Determine whether coating or restoration is appropriate, or whether another roofing solution makes more sense.

STEP 04

PREPARE & REPAIR

Correct appropriate problem areas and prepare the roof for the selected coating system.

STEP 05

APPLY

Apply the coating system according to the requirements of the selected system.

STEP 06

MAINTAIN

Recommend ongoing inspections and maintenance after completion.

Keep the roof on a schedule. After a coating project, a coated roof can be added to WW's Commercial Roof Maintenance program so it's inspected regularly and small issues are caught early.

Coating Experience

About 25 Years of Commercial Roof Coating Experience

WW Construction & Roofing brings approximately 25 years of experience working with roof coatings to every commercial roof evaluation and coating project.

That experience shows up in the parts of the job that matter most: recognizing when a roof is a good coating candidate and when it isn't, knowing which problem areas need to be corrected first and preparing the roof properly before any coating goes down.

FAQ

Commercial Roof Coating Questions

Is my commercial roof a good candidate for a coating?

A roof is usually a better coating candidate when the existing system and substrate are still sound, the problem areas can be corrected and there isn't extensive trapped moisture. Saturated or damaged materials, significant substrate deterioration, structural concerns, severe drainage problems or failed areas that need removal can rule a coating out. WW inspects the roof before recommending one.

What types of commercial roofs can be coated?

Depending on condition, coating systems may be an option for many low-slope commercial roofs, commercial metal roofs and existing spray foam roofs, as well as some single-ply, modified bitumen and built-up roofs. The coating system has to be compatible with the existing roof surface, and the roof has to be properly prepared first.

Will a roof coating stop my roof leaks?

Not on its own. A coating protects the surface of a roof that's in suitable condition, but it is not a substitute for fixing the source of a leak. Failed flashings, open seams, loose fasteners and damaged areas should be repaired before coating so the problems aren't simply covered over.

How long does a commercial roof coating last?

It depends on the coating system, how thick it's applied, the condition of the roof underneath and how well the roof is maintained. Many coated roofs can be inspected and recoated later rather than replaced. WW explains what to expect from the specific system recommended for your roof.

Can you coat a commercial metal roof?

Yes, when the metal roof is a suitable candidate. Fasteners, seams, laps, transitions and rust or corrosion areas need to be addressed first, because a coating won't stay sealed over loose fasteners, open laps or active corrosion.
