Roof Framing
1. Roof frames should be well achored.
2. Rafters and trusess should be straight, level and parallel to each other.
3. Regular spacing between rafters and trusses should be based on metal thickness and profile of roof to be installed. R Refer toTtable on Allowable Loads Per Square Foot.)
4. Provide top grid along ridge line and bridging at midspan between rafters parallel to grid.
5. Double rafters should be provided with 0.10 meter (4 in) clear space between rafters along valley gutter line.
6. Gutters should be installed before any roofing is laid.
7. Insufficient roof framing anchorade bring about the danger od wind and storm pressure lifting of the whole roofing including the roof framing system
1. If possible, carry out all panel cutting on a flat surface.
2. Use a straight edge as a guide and mark off the length where the cut is to made.
3. Roof panels must be free from concreting works cement, water -proofing compounds chemical solutions, paint, welding sparks,nails or iron tools. Removal or scraping of such may cause damage to the roof panels
4. Scaffoldings should have protective caps on the points of contact with the roof and should be rested with care on roof edges, gutters and end-flashing to prevent dents and scratches.
5. Roof traffic should be minimized. When crossing the roof area, walking should be conducted along roof frame locations, along overlaps or on wooden planks laid over the roof panels walking on the ridges or valleys between the purlins may dent the roofing.
6. TV antenna installations should be coordinated with Puyat Steel for proper installation.
Cleaning Up
1. Pick up all discarded scrap materials, especially ferrous metals such as nails and wires
2. Immidiately wash all plastering site with water
3. Clean all gutters of leaves and other waste refuse to prevent clogging at downspout areas and allow the continuous flow of water.
4. To attain its original bright luster finish, wipe the panel with a wet rag and fallow up with a clean rag.

Proper Installation and Maintenance Procedures
Roof Caring During Installation
APO Galfan Storage Reminder
1. Panels should ne stocked neatly in a dry and covered areas tp prevent cappilliary action which could couse rainwater or condensation to be drawn between sheets
2. If it is necessary to store the panels in the open, cover completely with loose tarpaulin or similar material and stack with one end slightly elevated
3. Remeber that permanent damage may result if the panels remain wet and clustered together for a long period of time.
