In Centralia’s older housing stock around the Historic District and Downtown, asphalt-shingle and cedar roofs from the early 1900s often develop wind-driven leaks during the region’s extended wet winters. Emergency tarping uses 10-mil reinforced polyethylene secured with 2x4 sleepers and perimeter furring strips to create a watershed that channels rain away from compromised valleys and flashing without trapping moisture against the decking. Crews must work around narrow downtown lots and mature trees near Borst Park that limit crane access, so hand-carried panels and roof-edge anchors become essential.
Mild summers allow tarps to remain in place longer while permanent repairs are scheduled, but UV exposure still degrades material within 60–90 days, requiring inspection every three weeks. Near Centralia College, student rentals with deferred maintenance frequently need tarps over multiple roof planes after ice-dam melt in January. Lewis County code requires any tarp covering more than 25 percent of a roof to be permitted within 72 hours when the structure is occupied, so crews coordinate with the city building department the same day the tarp is installed.
Soil saturation common along the Chehalis River corridor increases attic condensation under a tarp, so ventilation baffles are added at the eaves before the tarp is tensioned. Homeowners in the Borst Park neighborhood often discover that previous patch tarps left behind hidden rot once the new layer is removed, turning a simple tarp job into a decking assessment.
Technician insight
In Centralia, the thing that catches most people out with Emergency Tarping is how quickly the wet Lewis County winters turn a small ridge-cap leak into widespread decking rot on 1920s homes in the Historic District; once the tarp is on, homeowners often realize the previous owner’s patch jobs have hidden damage that changes the whole repair timeline.
Borst Park Area Roof Leak After December Windstorm
Heavy rain driven by a December gale pushed water under lifted shingles on a 1928 home near Borst Park. We found saturated insulation over two bedrooms and a sagging valley. A multi-plane tarp with added eave vents was installed the same afternoon, stopping all new moisture and allowing the family to stay in the house while insurance arranged permanent repairs.
