What Questions Should You Ask a Roof Waterproofing Specialist?

Waterproofing your roof isn’t just about protecting your home from water damage—it’s an investment in your property’s longevity, safety, and value. Whether you’re dealing with leaks, seepage, or simply taking preventive action, hiring the right roof waterproofing specialist is critical.

However, with so many contractors in the market, how do you separate the professionals from the amateurs? The answer lies in asking the right questions.

In this blog post, we’ll walk you through the essential questions to ask a roof waterproofing specialist—and why each one matters. Plus, we’ll highlight Lakhwa Chemical Services, a leading name in the waterproofing industry in Pakistan, known for its expert solutions and quality assurance.

1. Are You Licensed and Insured?

The very first question you should ask is whether the waterproofing contractor is licensed and insured. This provides legitimacy and protects you from liability in case of on-site injuries or accidental damage.

Why it matters: A licensed contractor follows industry standards and safety protocols. Insurance ensures you won’t be held responsible for accidents or damage during the job.

Tip: Lakhwa Chemical Services is fully licensed and operates under strict compliance with industry regulations.

2. What Type of Waterproofing Methods Do You Use?

There are different methods of roof waterproofing—such as liquid membrane coating, bituminous membrane, polyurethane foam, and more. Ask the contractor what systems they recommend and why.

Why it matters: Each roof type and environmental condition may require a different approach. A qualified specialist should be able to explain why a specific method suits your roof best.

Lakhwa Chemical Services specializes in a wide range of waterproofing solutions, including chemical-based treatments and heat-proofing technologies tailored for the harsh climate of Pakistan.

3. What Materials Will Be Used?

Inquire about the brand, quality, and lifespan of the waterproofing materials being used. Not all chemicals and membranes are created equal.

Why it matters: Poor-quality materials may degrade faster, requiring more frequent repairs and costing you more in the long run.

Lakhwa Chemical Services uses premium-grade waterproofing products, ensuring durability and long-term protection for your property.

4. Can You Share Case Studies or References?

A reliable specialist should have a portfolio or references from previous clients. Ask for case studies, before-and-after photos, or even site visits to ongoing projects.

Why it matters: Testimonials and past work offer insight into the company’s experience, reliability, and quality of execution.

Lakhwa Chemical Services is proud to have completed hundreds of projects for residential, commercial, and industrial clients. Their website and team can share real-world examples upon request.

5. What Is the Estimated Project Timeline?

Knowing how long the work will take helps you plan better—especially if you’re living in the property or managing a commercial facility.

Why it matters: Delays can cause inconvenience and may even lead to additional costs if not managed properly.

Lakhwa Chemical Services offers realistic timelines based on project scope and weather conditions, ensuring minimal disruption to your routine.

6. Do You Provide a Warranty or Guarantee?

Any credible waterproofing specialist should offer a warranty on their services. Ask what kind of guarantee is provided and what it covers—materials, labor, or both.

Why it matters: A warranty is your safety net. It shows that the contractor stands behind their work.

Lakhwa Chemical Services provides service warranties depending on the treatment type—some even up to 10 years—giving you peace of mind.

7. How Do You Prepare the Roof Before Waterproofing?

Proper surface preparation is crucial for effective waterproofing. Ask how they clean, repair, and prime the surface before applying any chemical treatments.

Why it matters: Skipping this step leads to peeling, bubbling, and eventual failure of the waterproofing layer.

Lakhwa Chemical Services follows a rigorous preparation protocol—cleaning, crack filling, and priming—to ensure maximum chemical adhesion and long-lasting protection.

8. How Do You Handle Drainage Issues?

Waterproofing isn’t just about creating a barrier—it’s also about ensuring proper water flow and drainage. A specialist should inspect and advise on drainage points and slope correction if needed.

Why it matters: Water pooling can cause waterproofing to fail prematurely and may lead to structural damage.

Lakhwa’s team evaluates drainage as part of their comprehensive waterproofing inspection and includes corrective solutions where necessary.

9. What Is the Total Cost, and What Does It Include?

Get a detailed, written estimate covering labor, materials, surface preparation, and post-treatment inspections. Ask if there are any hidden or additional charges.

Why it matters: Clear financial understanding avoids disputes and ensures transparency.

Lakhwa Chemical Services offers free site inspections and provides clear, competitive quotes with no surprise costs.

10. What Is Your Experience with Roofs Like Mine?

Every roof is different—concrete, metal, sloped, flat, etc. Make sure the contractor has experience with your specific roof type and structure.

Why it matters: A specialist familiar with your kind of roof will understand its vulnerabilities and requirements.

With years of hands-on experience across varied roof types, Lakhwa Chemical Services is equipped to handle residential homes, commercial buildings, and industrial facilities with precision.
