What flat roof work do we do in Portstewart?

Torch-on felt roofing

For a commercial roof in Portstewart, such as a shop, surgery or club, torch-on felt offers a hard-wearing mineral finish that takes occasional maintenance traffic. Phased work keeps part of the building weathertight while the rest is re-roofed, so the business can usually keep trading.

Emergency leak repairs

Leaves and debris build up in outlets and gutters on flat roofs around Portstewart, especially under trees. A blocked outlet can turn a normal rainstorm into a flood over the upstands. Clearing it is often part of the emergency visit, and the permanent fix looks at why it blocked.

Liquid-applied roofing

For businesses and landlords in Portstewart, a cold-applied liquid roof means no flame on site and, with some systems, a short cure time. That can make it easier to work around occupied buildings, tenants and opening hours than a system that needs hot works or a long strip-out.
