Which flat roofs are common in Glasgow City?
Flat roofs in Glasgow City sit on newer estates where the first extension roofs are now being replaced, bungalows with flat-roofed side extensions and dormers and lock-up garage blocks on estates. Scotland averages roughly 1,570 mm of rain a year, with the west far wetter than the east, so drainage, falls and wind uplift are part of every specification we write. Approximate 1991–2020 regional averages based on Met Office data.
Building standards in Scotland
In Scotland a building warrant is usually needed for alterations, structural work and new roofs; like-for-like repairs to a covering can be exempt. Section 6 of the technical handbooks sets a domestic roof benchmark of 0.12 W/m²K, applied as far as reasonably practicable on an existing roof. In Glasgow City the application goes to Glasgow City Council (building standards). More on the rules.
Why do small porch and bay roofs carry a minimum charge?
Because a small roof needs nearly the same set-up as a larger one: a team, safe access, materials, trims, waste removal and travel. The roof area is only part of the cost.
A 2 m² canopy and a 6 m² bay still both need a full strip, a deck check, edge trims, a wall flashing and the same care at the drip edge. That is why our full re-roofs carry a minimum charge rather than being priced purely per square metre. It is also why bundling makes sense: if you have a porch, a bay and a garage, pricing them together usually works out better than three separate visits.
The junction with the house wall deserves the most attention on a porch. Many leaks blamed on a porch roof are actually water tracking behind a failed flashing or through porous brickwork above. We check the wall, the flashing and the frame head before recommending a new roof. If the problem is only the flashing, a targeted repair may be enough. Our flat roof leaks guide explains how leaks are traced.

Why is my porch roof leaking when the felt looks fine?
The water is often coming from the wall junction, not the roof surface. A failed flashing, cracked mortar or porous brick above can let water in behind the upstand.
Can a canopy over a front door be re-covered?
Yes. Small canopies are re-covered in the same way as porches, usually in EPDM or GRP, subject to the minimum charge.
Can you re-roof a porch and a garage on the same visit?
Yes, and it is often better value. Combining small roofs spreads the set-up and travel costs.
