Metal roofs provide incredible durability and longevity, but their ability to transfer heat efficiently may lead to uncomfortable attic temperatures during summer and heat loss during winter – straining your HVAC system and energy bill. Foam board insulation may be just what’s needed! But How to attach foam board insulation to metal roof?
At ONLY ROOFING, we believe that comfort in the home and energy efficiency are paramount. This DIY tutorial will demonstrate how to supplement your metal roof with foam board insulation.
Things You Need for Work

- Measuring Tools: Tape, ruler, and straightedge.
- Cutting Tools: Utility knife.
- Installation Tools: Use a drill and the right drill bits for metal and wooden, construction adhesive for metal and foam board, and screws with washers for metal roofing.
- Insulation Materials: Scaffold boards and spray foam insulation.
Instruction to Insulate Your Metal Roof with Foam Board
1. Put Safety First
Before starting any roofing project, you should ensure you have all the required safety equipment including a well-fitting harness and safety work clothing.
2. Measuring and Cutting
First measure and plan out your roof space accurately before cutting foam board panels using a straightedge and utility knife for an exact fit without gaps between panels.
3. Prepare Your Metal Roof (Optional)
While not always necessary, cleaning the metal roof using a damp cloth to remove dirt or debris that might interfere with adhesion may help improve adhesion and adhesion rates. Any harsh chemicals could compromise roof coating integrity – avoid these treatments!
4. Attaching Foam Board
There are two methods available for attaching foam board to metal roofs:
- Direct Adhesion: Apply an ample layer of construction adhesive suitable for metal roofing to the back of a foam board panel and allow it to dry according to manufacturer instructions before pressing it onto your metal roof surface. Secure with screws and washers made for metal roofs ensuring they penetrate purlins for secure hold.
- Furring Strips (Recommended for Uneven Surfaces): When dealing with uneven roof surfaces or needing an air gap for ventilation, furring strips may provide the solution. Attach furring strips securely to purlins using screws and washers before attaching foam board panels using construction adhesive and attach them directly onto furring strips with screws/washers as shown above.
5. Fill Gaps and Seams (Optional)
When trying for an optimal fit, fill any small gaps or seams between foam board panels with spray foam insulation to maintain an uninterrupted insulation layer.
