Accurate measurements are the foundation of a successful DIY patio or carport project. Measuring correctly from the start helps ensure your kit is designed properly, quoted accurately, and installed without delays or costly changes.
This How to Measure for a DIY Patio or Carport Kit guide walks you through the key steps to capture the information needed before requesting a quote.
Step 1: Identify Your Attachment Type
Before measuring, determine how your structure will attach:
-
Flyover (above roofline)
-
Wall attached (brick or timber)
-
Fascia attached (metal or timber)
-
Freestanding (posts only)
Your attachment type affects roof height, projection, and post placement.
Step 2: Measure Width (Along the House)
The first measurement is along the house or structure where the roof will be installed.
✔ Measure the full width you want covered
✔ Measure parallel to the wall or fascia
Step 3: Measure Projection (Out From the House)
The second measurement is the projection, measured outward from the wall, fascia, or roofline.
✔ Measure perpendicular to the house
✔ Include desired overhang and gutter allowance
This measurement is critical for roof panel sizing.
Step 4: Check Heights & Clearances
-
Ceiling height under the roof
-
Vehicle height (for carports)
-
Door and window clearance
-
Roof pitch requirements
Step 5: Identify Obstacles
Note any:
-
Downpipes

Windows or doors
-
Gas lines or meters

Existing structures
This helps ensure posts and beams are positioned correctly.
Step 6: Confirm Roofing Type
Choose:

Insulated roofing for comfort
-
V-Line roofing for airflow and affordability
Your roofing choice impacts panel length and roof design.
