Decoding the ‘Roofing Free Quote’ in Sussex
Every week in Brighton, Hove, and Worthing, I sit down with property owners who are staring at three completely different pieces of paper, all claiming to be a roofing free quote. One is suspiciously cheap, one seems average, and the other is double the price. As an independent specialist with 18 years of experience, I can tell you exactly why this happens: a quote is only as good as the technical diagnostic assessment performed beforehand.
Many homeowners assume that a quote for sudden water ingress on felt systems covers the exact same materials and processes regardless of who wrote it. In reality, a vaguely written free quote is often hiding massive technical omissions. To prevent you from paying for the same job twice, I want to explain exactly how to read an estimate like a tradesman, and what critical details are usually missing from the cheapest options.
The Trap of the ‘Overlay Only’ Estimate
One of the most common reasons a roofing free quote comes in suspiciously low is because the contractor is only quoting for an overlay. This means they plan to torch new SBS-modified bitumen felt directly over your existing, failing covering. While overlays are occasionally appropriate for structures in sound condition, they are often a recipe for disaster on older Sussex properties.
If your current system has failed, water has likely bypassed the waterproofing layer and saturated the timber decking or insulation below. If a roofer simply traps this moisture under a new layer of felt, the sun will heat the trapped water, turning it into vapour. This causes blistering, loss of adhesion, and premature failure of the new membrane—a process known as interstitial condensation. When I survey a property, I am checking the integrity of your OSB or timber decking. A genuine quote must explicitly state whether the deck is being stripped and replaced, or you risk paying for a cosmetic bandage over rotting structural timbers.
Missing Compliance: Part L Building Regulations
Here is a technical detail that is almost always missing from a quick, non-technical roofing free quote: thermal compliance. Under UK Building Regulations (Part L), if you are stripping and replacing more than 50% of a high-performance torch-on system, you are legally required to upgrade the insulation to meet current energy efficiency standards (creating a ‘Warm Roof’ system).
Many contractors ignore this regulation to keep their quote artificially low. They will strip the old felt, lay down a cheap cold system without upgrading the insulation, and leave you with a non-compliant result. This not only causes severe thermal bridging and interior condensation—often resulting in black mould on your ceilings—but it can also cause major legal headaches if you ever try to sell your property. A trustworthy quote will clearly specify a Vapour Control Layer (VCL), the required thickness of PIR insulation (usually 120mm to 150mm), and a high-performance cap sheet.
Flashing Specifications: The Devil is in the Lead
Another area where cheap quotes cut corners is the leadwork. Your property is most vulnerable where it meets a vertical surface, such as a chimney, parapet wall, or firewall. A vague quote might just say ‘renew flashings’. But what does that actually mean?
In Sussex, our properties are subjected to heavy coastal winds and driving rain. If a roofer uses cheap mastic sealant instead of properly chasing lead into the brickwork, capillary action will eventually draw rainwater upward and behind the flashing, causing severe damp indoors. A technically sound quote will specify the use of Code 4 lead (which expands and contracts without tearing), proper lead wedges to secure it into the mortar joint, and a flexible pointing finish. If a roofing free quote does not detail how the abutments and upstands will be finished, it is not worth the paper it is written on.
How I Provide a Reliable, Transparent Roofing Free Quote
I do not believe in hiding prices or rushing a diagnosis. Because I want you to have complete financial clarity before I even step foot on your property, I have built a transparent online calculator on my website. In about 30 seconds, you can input your dimensions and type to get an instant, realistic price estimate based on the actual high-grade materials and compliant systems I use.
If that preliminary estimate fits your budget, the next step is to schedule a professional site visit. I will personally visit your property, conduct a thorough structural survey, check for hidden damp and ventilation issues, and provide you with a fixed, detailed written quote. No guesswork, no hidden margins, and no technical corners cut—just honest, expert workmanship built to survive the Sussex coastal climate.
