Commercial Roof Surveys Available

Before commencing work on your commercial roofing project, we can perform a professional commercial roof survey to thoroughly assess the requirements of your roof repair or replacement.

How much will a new commercial roof cost?

The roof is one of the most important elements of any building and can also be one of the most expensive. If your commercial roof has reached the point where repair is no longer an option, you’ll need to consider the cost factors involved in a commercial roof replacement in order to help you budget.

As there are several factors to consider when replacing a commercial roof, there is not a set cost for this. We’ll be able to give you a more specific price once we’ve conducted a commercial roof survey and determined what work is needed. Some of the factors we’ll take into consideration when calculating your quote for a new commercial roof include:

  • The size of the roof and the accessibility of the area we’re working on.
  • The material used.
  • The installation time.
  • Complexity of the roof layout.

What are the signs of damage to a commercial roof?

When making the decision to replace or repair your commercial roof, you should take note of the first signs of damage to your roofing system. These include:

• Noticing stains on your walls, floors, or ceilings – Stains can often be caused by water seeping through your commercial roof.
• Water leaking – Whilst this may seem obvious, if there is water leaking through your commercial roof, this is a clear sign of damage.
• Problems with guttering – Blocked or broken gutters can cause a range of problems with your commercial roof, as rainwater does not have a clear exit route. This is a frequent issue with flat commercial roofs.
• A bad smell – If you can’t locate the source of a bad smell in your commercial premises, you should always check your roof. Damp insulation and mould are often the cause of bad smells. So, if you’ve noticed an odour that just won’t go away, ask a commercial roofing contractor to take a look.
• Damage to flashing – If the flashing on your commercial roof is damaged, it won’t be providing any protection from water damage. Keep an eye out for any rusting and peeling to your flashing. If you do spot any problems, call a commercial roofing contractor as soon as possible.

Should I repair or replace my commercial roof?

The decision whether to repair or replace your commercial roof will inevitably come down to the extent of the damage to your roof, and which option works out to be more cost-effective in the long run.

Before making this decision, you should get a commercial roof survey. Our commercial roofing contractors will thoroughly inspect your roof and find out exactly what the problem is and where the damage is located.

The majority of general wear and tear issues can be solved with a simple roof repair, or even just some basic commercial roof maintenance, such as replacing your leaf guards and removing debris.

It may be that the whole roof is damaged, or the problem could just be localised to one area. If the latter is the case, commercial roof repair could be a better option.

If you find that the same issues keep recurring with your commercial roof, then having repair work undertaken every few months could be expensive. In this case, it would probably be more cost effective to have a full commercial roof replacement.

It’s vital that you keep on top of roof maintenance and, if you spot anything of concern, book a commercial roof survey without delay. In this way, small problems with your commercial roof shouldn’t become bigger and more expensive ones.

Case Studies

This NHS Trust is one of England’s largest acute teaching trusts. The trust is investing millions of pounds to futureproof their and deliver energy and carbon reductions by improving roof insulation and through the installation of solar PV panels and air source heat pumps in hospital buildings. The repair of leaking roofs is an integral part of this process. This will reduce the Trust’s carbon footprint by 14,000 tonnes a year and guarantee energy savings of approximately £1.8 million a year for the Trust.

Mason House, Lichfield, Birmingham

Nursing home. 290m2 in total. A GRP roof was installed on the new extension to the nursing home less than 2 years ago. There have been a number of issues wrong with the roof, the coping stones being too small and the GRP installed onto plywood which has led to failure in the membrane. We have applied Topseal PU to all valleys and box gutters and Topseal GRP to the parapet detail to replicate the coping stone, colour matching the finished topcoat to the windows lintels. Guaranteed for 25 years.

St Thomas Church, Ashton in Makerfield

Grade 2 listed church. 37m2. Asphalt roof with numerous cracks due to movement in the substrate because of thermal expansion and contraction. Numerous repairs over the years. Topseal PU applied with a 20 year guarantee.

The presentation covers details of all of the Topseal BBA certified roofing systems and different application situations, the session is then finished off with Q&A’s.
