When it comes to roof repairs in Bury St Edmunds, the material you choose matters as much as the quality of the labour - here is what to know before you decide.
A roof repair carried out with the wrong material will fail sooner than one done correctly the first time. Price alone should not drive the decision. Understanding what each material does, how long it typically lasts and where it is best suited helps you have a more productive conversation with any roofer and judge their recommendation fairly.
Brandon Roofers carries out roof repairs across Bury St Edmunds and neighbouring areas. On every job, part of the conversation is about material options - because the honest answer is not always the same for every property or every type of repair.
When a tile or a section of tiles needs replacing, matching what is already there is the first consideration.
Concrete tiles are widely available, relatively inexpensive and come in a range of profiles. The downside is that the colour coating fades over time, so a new concrete tile can look noticeably different from its neighbours for several years. They are also heavier than clay, which rarely matters for individual tile replacements but is worth knowing if a larger section is being repaired.
Clay tiles are denser and less porous than concrete, which means they absorb less water and are less prone to frost damage over time. They are more expensive to buy and slightly more difficult to source in specific profiles, but they age more gracefully and tend to blend better when only a handful are replaced. On older properties where appearance matters, clay is usually the better choice if the existing tiles are clay.
When replacing a small number of tiles, a roofer who sources second-hand or reclaimed tiles of the correct profile can produce a much less visible repair than one who uses new concrete regardless of what is already there. It is worth asking specifically what material will be used and why.
Slate roofs require careful matching when individual slates are replaced. The two main options are natural slate and fibre cement slate.
One honest point worth making: fibre cement slate has a shorter expected lifespan than good natural slate. If the rest of a natural slate roof is likely to last another thirty years, fitting fibre cement replacements means those specific slates may need attention again before the rest of the roof does.
Lead has been used for flashings around chimneys, dormers and abutments for centuries, and it remains the best material for the job. It is soft enough to be dressed precisely to any shape, it expands and contracts without cracking, and when correctly installed it has a very long service life.
The alternatives - aluminium, zinc and various proprietary self-adhesive membranes - all have their place, but none match lead for longevity in a standard flashing application. Self-adhesive flashing tape is sometimes used as a temporary patch or in very low-pitch applications, but it should not be used as a permanent replacement for properly dressed lead at a chimney or parapet junction.
If a roofer proposes to repair a failed chimney flashing with tape alone rather than re-dressing the lead, ask why. The answer may be reasonable in context, but it is a question worth asking.
The code (thickness) of lead matters too. Code 3 is the minimum for most step flashing applications, but code 4 or 5 is more appropriate for back gutters and soakers where water volume is higher. A roofer who specifies the lead code in their written quote is demonstrating that they are thinking about the right material for the right location.
Flat roofs on garages, extensions and outbuildings are repaired using one of two main systems in most residential contexts: traditional layered felt or EPDM rubber membrane.
Traditional built-up felt is one existing system found on older garages and extensions. It is applied in layers using heat or cold-bonding adhesive. Individual sections can be patched, but a felt roof that is blistering, cracking or splitting across more than a small area is usually better re-covered in full rather than patched repeatedly. Ongoing patch repairs on an aged felt roof rarely provide a lasting result and can end up costing more than a re-cover over two or three years.
EPDM rubber membrane is now the standard choice for re-covering flat roofs. It is bonded in a single sheet, which eliminates the seams that are the most common failure point in layered felt. The material itself is flexible, handles temperature change without cracking, and has a significantly longer expected service life than torch-on felt. The upfront cost is higher than a like-for-like felt repair, but for a full re-cover it is almost always the better long-term value.
Traditional sand and cement mortar is used to bed ridge tiles and to point the joints in chimney brickwork. It does the job, but it is rigid, and rigid materials crack as the roof and stack move slightly with temperature change and settlement.
Dry-fix ridge systems use a mechanical clip to hold ridge tiles without mortar, relying on ventilated plastic fittings rather than a mortar bed. They are not appropriate on every roof, but on a property where mortar ridge failures are recurring, dry-fix is worth discussing. The absence of mortar removes the freeze-thaw cracking cycle that causes most ridge tile problems.
Flexible pointing compounds are sometimes used on chimney joints in place of traditional mortar. These can be a sensible choice where movement is the root cause of repeated mortar failure, though they are not a universal solution and their appearance differs from traditional pointing.
Whatever repair is needed, there are straightforward questions that will help you judge whether the proposed solution is right:
