Questions Dubliners ask before hiring

Do commercial roofing contractors in Dublin repair flat roofs?

Yes. Contractors offer flat-roof repairs, re-felting, waterproof membranes and replacement systems for commercial and industrial properties. Some also handle pitched, slate, tiled, copper, lead and zinc roofing. Inspection is commonly used to identify leaks or damage before the suitable repair is proposed.

Can commercial roofers in Dublin carry out roof surveys?

Some contractors provide inspections and surveys using drone imagery, thermal cameras and hands-on assessment. These can cover pitched, flat and industrial roofs and help identify leaks, damaged materials or structural concerns. Ask what the survey includes and whether a written report or quote follows.

Do Dublin roofing contractors offer guarantees on new roofs?

Guarantees vary by contractor and project. Examples include a stated 20-year guarantee on some new roofs, a minimum 10-year workmanship warranty and written structural guarantees for certain projects. Confirm the precise duration, covered work and conditions in writing before commissioning the roof.
