Repairing and coating an existing flat roof

We assess existing flat and low-slope roofs for business owners who need leaks repaired and a suitable waterproof surface restored. The service covers coating and waterproofing work on workshops, retail premises, offices and other commercial buildings.

Coating suitability depends on the existing membrane, adhesion, drainage and the condition beneath the surface. We explain the repairs needed first and whether a coating, local membrane repair or replacement is appropriate. Tell us about stock, equipment and customer areas that need protection while the work takes place.

Finding where water enters

Water may travel before it appears indoors. We relate the reported leak to roof details and drainage, then inspect the suspected area. Previous patches, blocked outlets and later equipment installations help explain why a leak may keep returning.

A recurring leak across several occupied areas calls for a roof-wide review rather than another isolated patch. Tell us which rooms are affected, whether the problem follows heavy rain or standing water, and what repairs have already been attempted. That history helps define the inspection and distinguish defects in the roof covering from water entering at walls or equipment.

Identifying the existing membrane

TPO, PVC, EPDM and asphalt roofs need different preparation and repair materials. Appearance alone can be misleading, particularly where the roof has already been coated. Product records and selected checks help establish what the new material must bond to.

For a coating project, the proposed system needs to be compatible with the existing roof and its repair materials. We review the condition of seams, previous patches and perimeter details as well as the main surface. Where records are missing, the scope may need investigation or a test area before a product and preparation method can be confirmed.

Wet insulation and unsound surfaces

New waterproofing cannot remove moisture trapped beneath the surface. Loose membrane, blisters, saturated insulation or damaged decking may require removal or further investigation. The condition review establishes whether a surface treatment is appropriate and which repairs come first.

Moisture beneath the membrane can turn an apparently straightforward coating job into a replacement or partial replacement project. The estimate should explain how suspect areas will be checked and treated. Covering them with a new finish leaves the underlying issue in place. If further opening-up is necessary, agree access, temporary protection and reinstatement before it starts.

Waterproofing work for low-slope roofs

Local membrane repairs

Repair compatible seams, punctures and splits where the surrounding roof can accept a sound patch.

Flashings and penetrations

Correct leaking junctions at curbs, pipes, walls and edges using details suited to the existing assembly.

Liquid-applied treatment

Apply a specified system over an eligible prepared surface, including its primer and reinforcement requirements.

Drainage repairs

Address blocked or defective drainage components and investigate persistent standing water rather than simply coating around it.

Coating or a new membrane?

Coating retains the existing surface and depends on its suitability. A new membrane can form part of recover or replacement and involves different attachment and edge details. The practical choice depends on moisture, substrate condition and the amount of repair needed.

A sound existing membrane may be a candidate for cleaning, detail repairs and a compatible liquid-applied coating. Widespread damage, poor attachment or substantial wet insulation can favor removal and replacement. A recover system is a separate option and requires its own assessment of loading, attachment, moisture and applicable project requirements.

We can discuss these routes as part of a commercial refurbishment proposal. If the roof combines flat areas and metal panels, the scope should identify each assembly separately rather than specify one coating for the entire building by default.

Details around rooftop equipment

A leak beside an HVAC unit can come from a flashing or from the equipment itself. We review the roof connection and identify where a mechanical contractor may be needed. Adding new roofing can also change the available flashing height around a curb.

Include planned HVAC changes in the discussion. A new unit, service walkway or pipe penetration can affect recently completed waterproofing. Coordinating that work helps avoid cutting through a finished roof and paying twice for the same flashing detail. Any work to equipment itself should be identified separately from the roofing scope.

Access, weather and occupied areas

Cleaning and application need suitable roof conditions. Air intakes, nearby vehicles and work above occupied rooms affect protection and the application method. Tell us about these restrictions when arranging the review so the installation can be planned around them.

Comparing waterproofing prices

Look at the preparation and repairs included before comparing the coating or membrane cost. Access, removal of loose material, wet areas and work at drains can make a substantial difference. The quotation identifies the treated areas and the finished system being proposed.

Ask for the roof area, preparation, repairs, coating system, application requirements and exclusions to be clear in each proposal. A lower headline rate may exclude wet insulation, drain repairs or edge details. Access arrangements and protection for the occupied building also belong in the comparison. Any warranty needs its own stated terms; a product name alone does not establish coverage.

Talk to our team

Request a flat roof waterproofing review

Request a flat roof coating estimate with the property address and current leak or roof concern. If you know the membrane or previous coating, send that information with any useful photographs.

You do not need to know the membrane brand before contacting us. Start with the address, the areas affected and whether you are planning coating, replacement or a wider roof refurbishment. We work directly with owners and those responsible for existing commercial properties. Call (210) 775-0995 to discuss a flat-roof project and the next assessment step.

Frequently asked questions

Flat Roof Coating And Waterproofing FAQs

Can any commercial roof be coated?

No. The surface must be compatible and sound, with moisture and existing defects addressed before the proposed coating is applied.

Will coating repair holes or loose panels?

No. Damaged metal, failed connections and other defects need their own repairs before coating.

Can a new coating go over an old coating?

Only where the old finish is suitable to remain. Adhesion, contamination and compatibility checks help establish the preparation required.

Is silicone always better than acrylic?

No. Product choice depends on the substrate, exposure, application conditions and future maintenance. Compare the specified system for your roof.

Does ponding-water resistance mean drainage can be ignored?

No. A coating does not increase drain capacity or correct the roof's fall. Persistent standing water still needs investigation.

Why do two coating quotes differ so much?

Preparation, repairs, primer, detail reinforcement and finished thickness can vary substantially. Compare those items as well as roof area.

Can the coating be applied in any weather?

No. Roof temperature, surface moisture, rain and curing conditions must fall within the selected product's limits.

Will a reflective coating reduce our energy bills?

It may reduce solar heat absorbed by the roof. Actual building savings depend on insulation, climate, HVAC use and other conditions.

Is an extra 10 or 20 years guaranteed?

No general lifespan promise applies to every roof. Review the actual proposed work and the terms of any applicable written warranty.

What information is useful before a coating survey?

The address, known roof material, existing coating name and current defects. Old product records and photographs help if available.

UK refurbishment experience, a Texas office

Refurbishment specialists

Our business grew through roof and cladding refurbishment in the UK. That experience shapes the work we now offer from our Texas office.

Repair what can be retained

We investigate the roof problem and explain what can be repaired, restored or replaced, so you can decide how to invest in the building.

Roofing and cladding together

We can coordinate roof, insulation, wall panel and drainage work, including the connections where separate repairs can leave problems behind.

A plan for your working building

We agree access, work areas and protection with your site team, including any restrictions needed while the roof is opened.
