Steps to roofing replacement

  • Roof inspection

    Inspection of the wood decking is a first step. Any soft wet or rotted piece needs to be replaced. This is very important because only when you have a solid base for your roofing structure your shingles will stay intact. Also, wood sheeting needs to be inspected to make sure that it is attached to the roof rafters the right way. You should have at least one nail every 12 inches.

  • Drip edge installation

    After wood decking is prepared we install drip edge at all edges of the roof. Drip edge is a piece of metal bend at 90 degrees to prevent rain from getting underneath roofing material on all edges.

  • Ice and water shield installation

    Next step is installing "ice and water shield" which is a special type of roofing underlayment. Ice and water shield sticks to the wood decking which prevents any water leaks. It must be installed at the bottom of the roof (usually up to 36 inches from the roof bottom edge) and at all roof penetrations (chimneys, pipe flanges, roof connections, etc.).

  • Roofing felt installation

    After ice and water shield is applied, the rest of the roof needs to be cover with roofing felt. Roofing felt prevents shingles from sticking to the wood. We always use heavy duty #30 roofing felt.

  • New roofing installation

    After the above steps are completed and the base is ready, we start laying out the new roof.

  • Site cleanup

    We clean jobsite daily. Here in LGC Roofing we believe that we have to leave our jobsite cleaner than it had been before we came in.

No matter if it is shingle roof, slate roof or metal roof replacement, surface preparation is always the same.
