Picking the wrong contractor for a commercial roof is a costly mistake. A failed domestic roof repair is an inconvenience; a failed commercial roof can close a business, damage stock, or invalidate a lease. Before you sign anything or hand over a deposit, there are specific questions worth putting to any roofer you speak to.
This page explains what commercial roofing work involves, what the main systems are, and what you should ask and check before you let anyone on your roof.
Commercial roofing is different from domestic work in scale, access, and the materials used. Many commercial buildings have low-pitch or flat roofs, which means water management is critical. The roof must shed water reliably without the steep fall that tiles and slates rely on.
The main systems used on commercial buildings are:
A good contractor will survey the existing structure before recommending a system. The roof deck, drainage falls, and any penetrations (rooflights, vents, plant equipment) all affect which system is right for the building.
These are not trick questions. Any experienced commercial roofer should answer them clearly and without hesitation. If they can't, keep looking.
A written specification matters more than a verbal quote. It should name the system, the membrane or felt grade, the number of layers, how the perimeter and upstands will be detailed, and how flashings will be finished. Without this, you have no way of checking whether the job was done to the standard quoted.
If a contractor refuses to provide a written spec, or says they will work out the details on the day, that is a red flag. The scope and materials should be agreed before a single tile or sheet is lifted.
Commercial roofing spans several quite different systems. A roofer who is skilled with profiled metal sheet may have limited experience of single-ply membrane detailing, and vice versa. Ask specifically about the system proposed for your building, and ask whether they have photographs or references from similar jobs.
Farm buildings, school roofs, and retail units each present different challenges around access, structural loading, and existing drainage. Experience with the same type of building matters.
On a working commercial site, access arrangements affect your staff, your customers, and your liability. Ask how scaffolding or platform access will be set up, where materials will be stored, and how the contractor plans to keep the building weathertight at the end of each working day if the job runs over more than one day.
Contractors who have not thought about this in advance often make problems for the building's occupants during the job.
Some contractors quote the work and then subcontract it to another team. This is not automatically a problem, but you should know who will be on your roof. Ask whether the team doing the work is employed directly or subcontracted, and whether the same person who surveyed the roof will be overseeing the job.
Flat and low-pitch roofs fail most often at the drainage points: outlets block, upstands crack, or new membrane is not bonded properly around pipe penetrations. Ask specifically how drainage will be handled. On a re-roofing job, will the outlets be replaced or just re-dressed? Will falls be checked and adjusted if necessary?
Poor drainage detailing causes ponding water, and ponding water shortens the life of any flat roof system significantly.
Commercial roofing quotes vary widely because contractors price different scopes. One quote might include stripping the old roof covering; another might assume you have already arranged for that. One quote might include new insulation boards; another might assume the existing insulation is adequate.
Before comparing prices, make sure each quote covers the same scope. Stripping and disposal of old roofing material, insulation upgrades, replacement of damaged decking, new flashings, and making good around penetrations are all items that sometimes appear in one quote but not another.
For single-ply and EPDM membrane roofing, the quality of the membrane itself matters. Ask the contractor which manufacturer's product they are using and whether it is being installed in line with that manufacturer's own specification. Correct installation to the manufacturer's specification is what gives you the best chance of the system performing for its intended lifespan.
Flat roof replacement on a commercial building is priced according to the area, specification, access difficulty, and whether old material needs stripping. Profiled metal sheet on agricultural or industrial buildings is priced differently, often by the square metre of sheeting plus fixings and ridge, with prices varying considerably by building size and profile type.
Any price significantly out of line with other quotes - higher or lower - warrants a clear explanation from the contractor.
If you have a commercial property in Heacham and you are not sure what condition the roof is in, the sensible starting point is a proper survey before you commit to any contractor or any system.
