Quiz Your Contractors – Western Flat Roofing’s Top Tips!

We know that choosing to get your flat roof replaced or a new one installed is a big decision, and that is why it requires a lot of thought and research when choosing which company you want to carry out the work.

Flat roofs are a huge financial commitment, and just like any other construction project, you want a professional, high-quality company; otherwise, you might be left with more of a mess after the construction process.

In this blog, we’re going to go through everything you should ask prospective contractors before starting a project with them.

Important Questions to Ask Your General Contractor

Are you Fully Insured with a contractor’s license? What Does Your Insurance Cover?

This is an important question, as if they are not, you and your property might not be protected. The company might have their insurance certificates online, but if not, you can go directly to them and ask for these, and what they cover, so you can be sure you’re protected.

What is your Guarantee?

When you get a flat roof installed, companies will give you a guarantee; in the flat roofing industry, it is usually 10 years.

However, sometimes this might only cover some circumstances. Before working with a company, get them to send you the guarantee terms and conditions in writing; this way, you can double-check exactly what this covers to see if it is worth going ahead with this company.

All of our flat roofs come with a manufacturer’s guarantee of 10 years plus. Contact our team to find out about these in more detail.

What Accreditations do you have?

An accreditation recognises the company’s competence and adherence to a set of standards. Most reputable companies will have accreditations and show them on their website.

At Western Flat Roofing, we hold Construction Line (Gold), Safe Contractor, and we are a member of the National Federation of Roofing Contractors.

Can you Show Me Previous Completed Projects & Reviews from Past Clients?

When asked, we jump at the chance to show off previous work, so it’s always important to ask this question. This allows you to see their skills and ensure they are the right company for you, and we believe this is one of the most important questions, as if they can’t provide previous examples, they might not be very good.

If they cannot provide reviews from previous clients or case studies of successful projects, this potential contractor may not be for you. You can also do your own research online to ensure they are a reputable company.

A Price Breakdown

When you get a quote, make sure it is an itemised breakdown of costs, showing exactly what the project requires and the price for each item.

It is important to remember, low cost usually equals low quality. Flat roof installations are expensive, but if you get a high-quality company to fit your roof, you will have fewer problems and save money in the long run.

If you are looking for a payment structure, ask about the payment schedules and how and when payments would be due. This kind of open and effective communication is the sign of a good contractor and will make them a good fit for you.

What Is the Estimated Timeline and Project Schedule?

Understanding the project timeline is key to keeping your construction project on track. Ask your contractor for a detailed schedule from start to finish, including any key milestones.

Discuss potential delays and how they plan to manage them so that your budget, resources, and expectations remain realistic. A well-organised timeline ensures that all trades and subcontractors coordinate efficiently, reducing downtime and helping the project run smoothly from the initial planning stage through to completion.

What Safety Measures Do You Follow?

Before hiring a contractor, it’s essential to ask about the safety measures they have in place. This includes not only the protection of workers but also safeguards for your property and anyone visiting the site.

A professional team should follow industry standards and trade association guidelines, use the right protective equipment, and ensure that all work areas are secure. Proper safety planning helps prevent accidents, damage, and legal complications, giving you confidence that your project will be completed safely and responsibly.

What Happens If Problems Arise?

Even the most carefully planned construction project can encounter unexpected issues, changes, or delays. Before hiring a contractor, ask how they handle these situations and what their process is for resolving problems.

It’s also important to discuss warranties and guarantees, both for the work performed and the materials used. A reliable contractor will have a clear system for addressing defects or damage, giving you peace of mind that any problems will be managed promptly and professionally, without affecting the overall timeline or quality of the project.

During this process, it’s important to notice their communication skills, work ethic and ability to stay on track and on time. If these don’t align with your own, then they may not be the contractor for you.

Before making a hiring decision, always do thorough research. Compare multiple potential contractors, check references, and review completed projects. When you ask a contractor these questions, you, the homeowner, can make a confident hiring decision, avoid red flags, and ensure your construction project runs smoothly.
