Flat Roofing Specialists in Hertfordshire
Flat roofing that goes the distance
A flat roof lives or dies by two things: the system chosen and the standard of the fitting. Get either wrong and you are looking at puddles and leaks within a year or two. Stanleys Roofing & Building Ltd fits, renews and repairs flat roofing for homes and businesses in Harpenden, St Albans, Welwyn Garden City and well beyond.
You will find flat roofs over extensions, garages, dormers, porches and a good many commercial units. Done correctly they ask very little of you for years on end. The trick lies in setting the right falls so rain runs off cleanly and that is something we have done time and again across the county.
The systems we install
We are not tied to one product, so we suggest whatever genuinely suits your building and your budget:
EPDM rubber membrane
A single sheet of rubber with almost no joins, hard wearing and a sound choice for garages, extensions and larger expanses.
GRP fibreglass
A tough, one-piece finish that copes happily with the odd bit of foot traffic and looks neat on a domestic roof.
Felt systems
Modern torch on felt, still reliable and good value when it is laid by someone who knows what they are doing.
We will run through the merits of each in everyday language, so the decision stays yours and is made with eyes open.
The detail is where it counts
Lay a flat roof properly and it should serve you quietly for many years. The weak points are nearly always the parts that get hurried, the upstands, the edges and the outlets, so that is exactly where we slow down and take care. The gap between a flat roof that lasts and one that needs an annual patch lives in those details, and our name rides on getting them right.
Repairs and replacements
If the flat roof you already have is leaking or simply worn out, we will give you an honest read on whether a repair is worth it or whether starting again makes better financial sense. A patch can buy a season or two, but once a surface has gone across the board a new covering usually pays for itself over time.

How we go about it
Our approach is calm and free of pressure. We come out, look the roof over and hand you a written price with nothing to pay up front. The figure we settle on is the figure you pay. The site stays clean while we work and is left clear once we down tools.
We carry out flat roofing right across Harpenden, St Albans and Welwyn Garden City, from a single garage to a sizeable commercial roof, the standard never drops with the size of the job.
