Replacing your home's roof is a significant project. While it can feel overwhelming, understanding the step-by-step process of a professional shingle replacement can give you complete peace of mind. For homeowners in Arlington, Texas, a roof replacement involves much more than simply nailing new shingles over the old layer. A high-quality installation requires a total tear-off, structural decking inspections, and advanced leak barrier underlayments. Here is our detailed breakdown.
1. Complete Tear-Off vs. Layover
Some contractors offer to install new shingles directly over your existing roof, known as a "layover." While cheaper, layovers are highly discouraged in Texas. A layover traps heat under the shingles, accelerating UV degradation and drying out asphalt oils. More importantly, it prevents the roofer from inspecting the underlying plywood decking for water rot. 3-R Roofing always tears off old shingles down to the bare wood deck to ensure a stable foundation.
2. Plywood Decking Inspections
Once the shingles are cleared, we inspect every inch of the wood deck for rotting, soft spots, or sagging rafter lines. Rotting wood cannot hold roofing nails securely, causing shingles to lift and fly off during wind storms. Replacing compromised decking panels ensures the structural integrity of your new roof.
"Installing new shingles over degraded, soft-rotting wood decking is a major failure. A proper replacement requires a clean deck inspection and structural wood swaps."
3. Synthetic Underlayments & Valleys
Traditional organic felt paper can dry-rot and tear during installation. We use advanced synthetic felt underlayment, which is tear-resistant and provides an extra layer of waterproofing. In critical water channels like valleys and around chimneys, we lay down self-adhering ice & water shields to prevent leaks from ice damming or heavy rain back-up.
