Choosing a specialist for tile, IBR or flat roofs

Your roof is leaking, or you've noticed tiles shifting, or the IBR's starting to rust. You've grabbed quotes from a few roofers, and they've all said yes, they can fix it—but one quote is half the price of another, one person won't commit to a timeline, and you're not sure whether any of them actually know the difference between your flat roof and the neighbour's pitched one. This is the moment most homeowners freeze.

Choosing the right specialist for your specific roof type isn't just about price or availability. The material underneath you—tile, IBR or flat membrane—demands different skills, tools and judgement calls. A person experienced with tile repairs may not have the depth of knowledge for an IBR standing seam, and someone comfortable on pitched roofs might approach flat-roof water management all wrong. The gap between "I can do roofing" and "I can do *your* roofing well" is where most problems live.

Match their actual experience to your roof material

Ask directly: "How many jobs like mine have you done in the last two years?" Ask for one recent example—not just any roof repair, but specifically tile, IBR or flat. Listen for detail in the answer. Someone who's spent the last year on tile replacements will talk about mortar types, underfelt, hip and ridge work. Someone with solid IBR experience will mention fastener corrosion, sealant degradation, and the way water sits at overlaps. A flat-roof specialist will discuss membrane type (EPDM, PVC, bitumen), ponding, and flashing integrity. Vague answers like "yeah, I've done lots" are a red flag.

If the roofer deflects or says they're comfortable with all three equally, ask why. Real specialists tend to develop depth in one area because the diagnostics and solutions are sufficiently different. There's nothing wrong with hiring someone who's strong in one material—but you need to know which one.

Check how they diagnose the problem

Before they quote, do they climb onto your roof, or are they quoting from ground level? Do they ask about the age of the roof, the direction it faces, whether you've had previous leaks or repairs, or how the problem first showed up? A thorough specialist will spend 20–30 minutes investigating, not five minutes measuring. They should ask where water entered (inside ceiling, walls, or visible on the roof itself), whether it happens only in heavy rain or persistent drizzle, and what season it's worst.

This investigation matters because tile roofs can hide leaks under the tiles for months; IBR leaks often track sideways along the fasteners; flat roofs can pond water where you can't see it. A roofer who skips diagnosis is gambling on your budget, not solving your roof.

Understand what they're actually proposing

Their quote should specify:

• Exactly which material is being replaced or repaired (three tiles, a 2m² section of IBR, a resealed area)
• What preparation work is included (removal of old material, clearing gutters, flashing checks)
• Whether they're fixing the visible damage or investigating the root cause
• Timeline and whether they'll protect your interior during work
• Any warranty on their labour or materials

If the quote is vague, ask them to itemise it. A good specialist can explain why they're doing each step. If they can't, they may not have thought it through.

Test their communication and availability

Can they send you a quote in writing within a few days? Do they respond to calls or WhatsApp? Will they confirm a start date in writing before you hand over a deposit? Roofing isn't emergency work in most cases, so you shouldn't feel pressured to decide instantly. A specialist who's booked three weeks out but clear about their process is often more reliable than someone who can start tomorrow but won't explain their approach.

Your choice ultimately rests on whether this person understands your specific roof type, has diagnosed the real problem, can explain what they'll do, and communicates clearly. Those four factors matter far more than getting the cheapest quote.
