What full EPDM renewal can improve
Deck checked beneath
Soft or damp substrate problems are found before the new membrane goes on.
Fewer vulnerable joints
A continuous EPDM covering reduces weak seams across the roof area.
Drainage improved
Renewal is a chance to correct falls, outlets and perimeter details.
When patching a flat roof stops paying off
A flat roof can soak up time and money once the problems spread beyond one small weak spot. If the membrane is failing across a wider area, leaks keep returning or the deck beneath has been damaged by moisture, replacement is often a better bet than a chain of patches. We inspect the roof to see whether the issue sits in one detail or whether the failure runs deeper across the build-up. EPDM is useful here because it forms a continuous waterproof covering with fewer vulnerable joints than many older flat-roof systems. With MTS Northants, the aim is to solve the cause of the trouble, not cover it over with a neater version of the same problem. In Rushden, that usually means being honest about when repair has stopped earning its keep.


Strip back, check the deck, build it right
Complete replacement starts by removing the failed covering and assessing the substrate below it. The deck needs to be clean, stable and dry enough to do its job before the new membrane is fitted. Renewal also gives us the chance to improve the details that affect performance, such as falls towards outlets, perimeter trims and the way the roof meets walls and penetrations. A quotation from MTS Northants makes clear what has failed, what condition the support beneath is in and whether the replacement will include improvements to drainage and edge detailing as well as the new EPDM finish.
