What we cover

What flat and low-slope roofs covers.

Flat and low-slope roofs behave differently from shingled ones: water sits, so seams, edges and drains matter most. We look at how the roof drains, where the membrane has opened and what is under it before recommending anything.

Depending on the roof, we may recommend patching, re-coating or a full replacement with a modern membrane system. We will explain the options plainly and quote each one.

Flat roofs are often smaller than a main roof, but a failed one can damage the walls and ceilings below. A short inspection shows whether it needs a patch or a plan.

FAQ

Our attic had frost on the nails every winter. They explained how ventilation and insulation work together and fixed the ventilation part. They told me which part another trade should handle.
