Garage Roof FAQs
How long does a garage roof last?
Felt roofs: 10-20 years. GRP/EPDM: 25-50 years. Pitched tiles: 50-80+ years. Regular maintenance extends life significantly.
Is GRP worth it for a garage?
If you plan to keep the garage long-term, GRP is excellent value. It's seamless, walkable, and typically lasts 25-40 years with no maintenance.
My garage has asbestos - what now?
Asbestos must be removed by a licensed contractor. Budget €800-2,000+ for removal and disposal, plus the new roof cost.
Can I convert a flat garage to pitched?
Yes, many homeowners do this for better drainage and aesthetics. Costs €4,000-8,000 depending on size. May need planning permission.
Do I need planning permission?
Replacing like-for-like: usually exempt. Changing style (flat to pitched) or increasing height: check with your local authority.
