Finding the Right Roofer: A Homeowner's Practical Guide

Your roof is the thing standing between your family and the weather. A bad roofer job can cost you thousands in water damage, structural problems, and insurance headaches. I've seen people lose tens of thousands because they picked the wrong person for the work.

The problem is that roofers aren't like furniture shopping, where you can return something if it doesn't work. A roof is there for 20 to 50 years depending on the material. Getting it wrong from the start affects everything else, including the resale value of your home.

Check Their Qualifications and Insurance

Start with the basics. A legitimate roofer should have:

• Public liability insurance, typically £6 million minimum
• Employers' liability insurance if they have staff
• CSCS card or equivalent trade qualification
• Membership with a recognised body like the National Federation of Roofing Contractors

Ask to see their certificates. Don't just take their word for it. A genuine professional will have these documents ready without fuss.

Phone their insurer to verify the cover is current. This takes five minutes and could save your deposit if something goes wrong.

Ask About Their Experience Specifically

"How long have you been doing this?" is a start, but you need more detail. Ask them:

How many roofs of your type have they completed? A roofer experienced with slate tiles might be out of their depth with modern flat roof systems. If you've got a pitched tile roof, you want someone who's done hundreds of them, not someone who does it occasionally between guttering jobs.

What training have they done recently? Roofing standards change. New waterproofing membranes and ventilation rules come in regularly. Someone who qualified 15 years ago but never updated their knowledge will miss these.

Can they give you three references from jobs completed in the last two years? Phone those people. Ask if the work stayed dry, if the roofer turned up on time, and if the final bill matched the quote.

Get Multiple Written Quotes

Three quotes minimum. Get them in writing. A quote scribbled on the back of a receipt isn't a contract, and it leaves you exposed.

Each quote should specify:

• What materials will be used, with brand names
• How many layers will be removed or added
• Waste disposal method and who pays for it
• Timeline for the work
• Payment schedule (deposit, milestone payments, final payment)
• Guarantee period and what it covers

If one quote is dramatically lower than the others, that's a warning sign. They're either cutting corners or they've missed something in their calculation.

Watch Out for Dodgy Practices

Some roofers use high-pressure tactics. They'll tell you the roof is about to fail and you need to decide today. This almost never happens. A roof in genuine danger shows water inside your home, not just uncertainty from a survey.

Be wary of anyone who won't give you a written quote. Be wary of anyone who wants full payment upfront. Be wary of anyone who won't provide contact details for recent work.

Cold callers offering discount roofing because they're "in the area" are particularly suspect. Legitimate roofers get work through reputation and recommendation, not knocking on doors in your street.

Check Online Reviews, But Think Critically

Google reviews and Trustpilot are useful, but read them properly. Look for patterns rather than isolated complaints. One person saying a roofer was rude is different from ten people saying the roof leaks three months later.

A company with 50 reviews and 4.2 stars has probably done real work. A company with three 5-star reviews and a website launched last month is more questionable.

Check if they respond to negative reviews. A good tradesperson will acknowledge problems and explain what went wrong. That shows professionalism.

Understand the Guarantee

Most roofers offer a 10-year guarantee on their labour. Materials usually come with separate manufacturer guarantees, often 20-30 years for quality tiles or slates.

Get the guarantee in writing as part of your contract. Know what it actually covers. Does it cover leaks from normal wear? Does it cover wind damage? Does it require you to pay for inspections or maintenance?

If they offer a 50-year guarantee, be sceptical. They won't be trading in 50 years, and the guarantee is worthless if the company folds.

Trust Your Gut on Communication

You'll be paying someone thousands of pounds. They should be clear in how they talk to you. If they use jargon without explaining it, that's a bad sign. If they avoid your questions, walk away.

A good roofer will explain what's wrong with your current roof, why they're recommending specific materials, and how long the work will take. They'll answer your questions directly.

Making Your Final Choice

Narrowing it down usually means weighing reliability against cost. The cheapest option isn't always the worst, but it usually is in roofing. A £2,000 difference in quotes for a small repair might mean different materials or different timescales. A £5,000 difference for a full roof replacement is usually a red flag on one quote or the other.

Once you've chosen, get everything in writing before they start. Your deposit should be reasonable, perhaps 10-20 percent, with the balance due on completion. Never pay in full upfront.

Your roof protects everything else in your home, from the furniture you've invested in to your family's comfort. Get this decision right, and you'll have peace of mind for decades.
