A Cure It roofing kit is a packaged solution for building a flat or low-slope roof from glass-reinforced polyester, commonly called GRP or fiberglass. The system combines resin, reinforcement, topcoat, and compatible trims to create a continuous waterproof surface. Cure It is a UK roofing brand, so U.S. buyers should check product availability, shipping, local code requirements, and installation guidance before ordering. Understanding the kit’s components and limitations helps homeowners compare it with locally available roofing systems and plan the project more reliably.
What Is a Cure It Roofing Kit?
Cure It is a branded GRP roofing system designed primarily for flat and low-slope roofs. GRP is made by combining polyester resin with glass-fiber reinforcement. Once the materials cure, they form a rigid, waterproof laminate. A protective colored topcoat provides the visible finish and helps shield the roof surface from weather and ultraviolet exposure.
A roofing kit packages key materials for a defined roof area. It is not necessarily a complete roof-in-a-box: the exact contents depend on the supplier, kit size, and product configuration. Some components may need to be purchased separately, and the roof deck, insulation, drainage, edge details, and labor remain part of the project.
Unlike overlapping shingles or sheet membranes, a GRP roof is formed as a continuous surface over a prepared deck. Seams and junctions still need careful detailing, but the finished laminate can provide a neat, joint-minimized appearance. That result depends on correct surface preparation, compatible materials, suitable weather, and proper installation.
What Comes in a Cure It Roofing Kit?
Kit contents vary, so the supplier’s bill of materials is the best guide. A typical Cure It GRP roofing package may include some or all of the following:
- Resin: Polyester resin used to wet out and bond the glass-fiber reinforcement.
- Glass-fiber reinforcement: A mat or laminate layer that gives the cured roof its structural continuity.
- Topcoat: A pigmented finishing layer that provides the final color and protective surface.
- Catalyst: A hardener added in a specified proportion to initiate curing. It may be supplied separately or purchased as an accessory.
- Roof trims: Compatible edge, wall, or perimeter profiles used to create finished details. Trim selection depends on the roof layout.
- Tools and consumables: A roller, brush, mixing container, or other application items may be included in some packages but not all.
Not every kit contains a deck, insulation, vapor-control layer, roof outlets, fixings, or every trim required for a particular design. Buyers should confirm the kit’s coverage, included accessories, catalyst quantity, and compatibility with the planned substrate. Coverage figures depend on the system specification and site conditions; they should not be treated as a substitute for a measured materials takeoff.
How a GRP Flat Roof Is Built
A GRP roof is assembled in layers over a sound, suitable deck. The exact build-up and installation sequence must follow the current manufacturer instructions for the specific Cure It system. The outline below explains the typical process, not a substitute for product guidance or professional installation.
- Inspect and prepare the deck. The roof deck should be stable, dry, clean, and appropriate for the system. Damaged or uneven areas can affect adhesion and finish. Existing roofing may need removal rather than being covered.
- Plan edges and penetrations. Roof outlets, upstands, wall junctions, corners, and perimeter trims require deliberate detailing. Water should drain toward suitable outlets without being trapped by dips or poorly placed edges.
- Install compatible trims. Trims are positioned and fixed as specified, with their joints and transitions prepared for the laminate. Different roof shapes may require different profiles and accessories.
- Apply resin and reinforcement. Resin is mixed with the specified catalyst at the correct ratio and working conditions. The reinforcement is laid and wetted out so it is properly saturated and bonded, without dry areas or excessive pooling.
- Allow the laminate to cure. Cure time depends on the product, temperature, and other conditions. The surface should not be disturbed or coated before the instructions allow it.
- Apply the topcoat. The specified topcoat is applied to the cured laminate according to the system requirements. It forms the visible finish and contributes to weather protection.
- Check the finished details. The installer inspects edges, outlets, corners, and penetrations for defects, incomplete coverage, or other issues that require correction.
Resin and catalyst are reactive chemicals. Their safe handling, storage, mixing, and disposal should follow the product safety data sheet and local rules. Appropriate protective equipment and ventilation are important, and ignition sources should be controlled as directed by the manufacturer.
Advantages and Limitations
Potential advantages
- Continuous waterproof surface: A properly installed laminate avoids the broad field seams found in some sheet systems.
- Finished appearance: A colored topcoat provides a uniform surface, while compatible trims can create defined roof edges.
- Adaptability: GRP can be formed around many roof details when the system’s trims and installation methods are used correctly.
- Packaged materials: A kit can make it easier to identify core materials for a measured project, although it does not eliminate the need to verify quantities.
Limitations to consider
- Installation is detail-sensitive: Poor mixing, inadequate reinforcement saturation, unsuitable weather, or weak detailing can undermine performance.
- It is not a cure for a bad roof deck: A new surface cannot compensate for structural damage, inadequate drainage, or moisture trapped below the system.
- Product access may be limited in the United States: Cure It is a UK product, and local stock, shipping, technical support, and warranty coverage may not match those of domestic systems.
- Repairs and compatibility matter: Later work should use approved repair methods and compatible materials. A general-purpose coating should not be assumed to bond reliably to GRP.
Is a Cure It Roofing Kit Suitable for a U.S. Roof?
It may be technically possible to use a GRP roofing system in the United States, but product suitability is not established simply because the kit is available online. U.S. projects must account for local building codes, climate, wind exposure, fire requirements, roof slope, drainage, and the roof assembly beneath the surface. The applicable requirements vary by location and building type.
Before buying an imported kit, ask the manufacturer or authorized supplier for current technical documentation and confirm whether the system has approvals or test data relevant to the project and jurisdiction. A local building official or design professional can clarify permit and code questions. The installer should also confirm that the product is suitable for the intended deck, insulation, and roof configuration.
Shipping presents practical issues as well. Resin, catalyst, and other chemical products may have transport restrictions, and cross-border delivery can affect cost and timing. Confirm that the supplier can legally ship the materials to the destination, that the products will arrive within their usable storage period, and that technical support and warranty terms apply in the United States.
How to Estimate the Right Kit Size
Start with accurate measurements, not the building’s interior dimensions. Measure the actual roof surface, including any changes in shape, and account for parapets, upstands, rooflights, outlets, and other details. A roof with many edges and penetrations may need more material and trim than a simple rectangle of the same area.
Then compare the measured area with the supplier’s stated coverage for the exact system and application method. Confirm whether the coverage refers to resin, reinforcement, topcoat, or a complete package. Waste allowances and coverage assumptions can differ, so the supplier should confirm the quantity for the roof’s layout and details. Buying too little can create delays; buying an oversized kit can leave materials unused, and resin products may have storage limits.
A complete estimate should also include deck repairs, insulation or other assembly layers, trims, fixings, outlets, protective equipment, delivery, tax or import charges, and labor. If a contractor is installing the roof, request a written scope that identifies the specified system and what is included.
Cure It Roofing Kit Cost Factors
There is no dependable single price for a Cure It roofing kit without knowing the roof area, kit contents, supplier, and delivery destination. Online prices can also omit trims, tools, shipping, or materials needed for the substrate. U.S. customers should compare the delivered project cost rather than the kit price alone.
Important cost factors include roof size and shape, the amount and type of trim, deck condition, insulation requirements, labor rates, access to the roof, and disposal of old materials. Import costs and the availability of local product support can add uncertainty. A locally supported U.S. roofing system may have a higher or lower material price but be easier to source, inspect, and warranty.
When comparing quotes, check that each proposal uses the same roof area, preparation scope, assembly design, drainage details, and warranty assumptions. A low quote may exclude deck repairs or edge work that another contractor has included.
Choosing an Installer and Protecting the Warranty
GRP roofing depends heavily on workmanship. An installer should have relevant experience with the named system, understand the required substrate and detailing, and be able to explain how the roof will drain. Ask for recent examples of comparable projects and references, rather than relying only on general roofing experience.
Before work begins, request the current installation instructions, product data sheets, safety data sheets, and written warranty terms. Confirm which materials are approved, what weather and temperature conditions are allowed, how the deck will be prepared, and how outlets and wall junctions will be finished. Warranty coverage may depend on using specified components and approved installation methods.
After installation, retain product records, invoices, photographs of concealed details where practical, and maintenance guidance. Keep roof outlets clear and inspect the roof after severe weather. If a leak or surface defect appears, identify its cause before applying a patch or coating; an incompatible repair can make later work more difficult.
Cure It Roofing Kit vs. Other Flat-Roof Options
GRP is one of several choices for flat and low-slope roofs. Common alternatives in the U.S. include EPDM rubber roofing, TPO and PVC single-ply membranes, modified bitumen, and built-up roofing. Each system has different installation methods, seam details, material availability, and suitability for particular roof assemblies.
| System | Typical characteristics | Key comparison question |
|---|---|---|
| GRP / fiberglass | Resin-and-fiber laminate with a protective topcoat | Is a trained installer and compatible system support available locally? |
| EPDM | Flexible rubber membrane, often supplied in sheets | How will seams, edges, penetrations, and the selected attachment method be handled? |
| TPO or PVC | Single-ply membranes with heat-welded seams | Can the contractor provide the specified membrane, welding quality, and warranty? |
| Modified bitumen | Multi-layer asphalt-based roofing, available in different installation formats | Which assembly and application method fit the roof and fire-safety requirements? |
No system is automatically best for every building. The decision should account for climate, roof design, expected maintenance, contractor expertise, local code acceptance, and long-term access to compatible repair materials.
