Why Garage Roof Quotes Vary Wildly in Sussex
If you are looking to repair or replace your garage roof in Brighton, Hove, or Worthing, you have probably noticed a frustrating reality: quotes from different roofing firms can vary by up to 100% for the exact same job using the exact same materials. Let me explain exactly why this happens.
In the trades, price is heavily driven by supply and demand. If a roofing company is highly booked, they will often quote an artificially inflated price because they don’t desperately need the work. If you accept it, the massive profit margin justifies squeezing you in; if you decline, their calendar is still full. It is a classic business tactic. To be completely transparent, I also adjust my margins slightly based on my current workload—this is standard practice across the industry.
The Technical Side of Outbuilding Roof Failures
Regardless of what a company quotes you, the technical standard of the repair must be flawless. Many failing outbuildings suffer from cheap, aged pour-and-roll felt that splits due to thermal movement. Once a lap joint opens, capillary action draws water underneath the membrane, quietly rotting the timber beneath over the wet winter months.
When I replace a flat roof on an outbuilding, I strip it back to the bare joists. For long-term durability in our harsh coastal weather, we install heavy-duty OSB3 structural timber decking to eliminate sagging. Over this, I apply a high-performance SBS-modified bitumen torch-on felt system. The synthetic rubber mixed into the SBS bitumen allows the roof to stretch and recover with temperature changes, completely preventing the brittle cracking and blistering common in older roofs.
Instantly Benchmark Your Price
The problem with industry pricing games is that property owners waste weeks chasing down contractors, only to receive random, inflated estimates. I believe in total transparency, which is why you don’t even need to call me to find out what the job should cost.
