As you can see, there are a number of options open to building owners and all have their advantages and disadvantages and there is no single recommended course of action to suit all circumstances.

Cost is nearly always going to play a significant part of any decision making process, but sometimes, there are other factors that will influence a decision and we have seen several cases where a new roof has been the preferred solution, but it has simply not been possible for a number of reasons to achieve.

For this reason, we strongly recommend an initial site survey so that all possibilities can be explored fully to provide you with all of the facts necessary to make an informed decision.

Remember, as Chartered Building Surveyors, we offer unbiased advice based. The same is not true of roofing companies who usually only want to sell you the most profitable solution.
