A flat roof that leaks is not always finished. The decision depends on how widespread the damage is and whether the deck beneath is sound. Here is how we judge it on flat roofs in Pucklechurch.
Plenty of village homes have a flat roof somewhere, over a rear extension, a garage, a porch or a dormer. When one starts to leak, owners worry that the whole thing must go. Sometimes it can be repaired. Sometimes it cannot. Four or five straightforward checks usually settle it.
The deck is the deciding factor
What lies under the covering matters more than the covering itself. If the deck is dry and firm, a repair can hold well. If it is soft, stained or crumbling, any repair on top is built on sand. We find out which it is before suggesting anything.
You can often get a first impression from inside. A ceiling that sags, a stain that returns after painting or a damp smell in the room below all hint that the deck may have taken water for a while, which changes the answer.
When repair is sensible
A single split, a lifted seam, a failed joint around a rooflight or a blocked outlet are all things we can usually repair on their own. The rest of the covering should be in fair condition, without lots of old patches. A well-made repair can give a sound roof a good deal more service.
A good repair is specific. It deals with the exact fault, whether that is a split, a joint or an outlet, and it is done on a dry surface so it bonds properly. A quick smear over a wet crack rarely lasts through the next wet spell.
When replacement is more honest
If the covering is cracked, blistered or open at many points, or if water has soaked insulation in several areas, patching only chases the next leak. Widespread damage, a rotten deck or poor falls leading to deep ponding are signs it is time to strip back and start again.
- Cracks and blisters across much of the surface
- Many layers of old patching
- Soft, sagging or stained deck
- Persistent deep ponding after rain
Different roofs, different answers
A small porch roof with one split may be a quick repair. A larger extension roof on a stone or brick house with old, failing coverings may call for full renewal. Later infill homes often have simpler roofs that are easier to repair or replace. We treat each on what we find.
Making the decision
We give you both options in plain terms, with what is included. If replacing, we talk through single-ply rubber, fibreglass and felt systems and which suits your roof, along with insulation and falls. Ask for photographs of what was found underneath, since the old covering hides a lot.
Falls matter too. A flat roof is never truly flat, and if water cannot run off, it will find the weakest spot. When we replace a roof, we look at whether falls and outlets can be improved so the new covering has an easier life.
Frequently Asked Questions
How can I tell if my flat roof can be repaired?
From inside, look for sagging or widespread staining. From outside, we check the surface, seams and edges, and test the deck. If damage is limited and the deck is sound, repair is often possible. We tell you plainly what we find.
Does a repair mean the leak will definitely stop?
If the cause is found and the deck is sound, a repair should deal with it properly. We trace the true source first, since patching in the wrong place is the commonest reason that leaks return after a repair.
Can I put a new layer over the old covering?
Sometimes, but only when the old roof is dry, firm and not hiding wet insulation. We check first. If moisture is trapped, we strip back to the deck so the new roof is not undermined from below.
