Need New Siding? Opt For A Complete Tear Off
Often, when one gets a new roof, the roof is placed over the old roof rather than completely torn off. This can be done with siding, too; however, there are several reasons why a complete tear off is best, even if it costs a little more.
Your Windows And Doors Will End Up Recessed
If new siding is placed over your old siding, the dimensions of the house's exterior increase by about an inch all around. This then makes your windows set back in from the exterior, which will reduce visibility. Most siders use a piece of trim called a J channel around the window and door openings to reduce this effect, but it doesn't look quite right. This can also be problematic as well. Water from rain and snowmelt can get into the gap around the window or door opening, which can lead to rot eventually.
A Complete Tear Off Allows For Inspection
If you're in need of new siding, your house is obviously older. Really old homes should always have a complete tear off. This will allow the contractor to assess the structural integrity of your home. Rotting boards and studs, insect infestation, entry points for rodents, and missing or rotting insulation, electrical or plumbing issues, and more can all be addressed. Adding a second layer of siding can increase the R-value, but it's not worth it if you are just covering up the underlying problems that are common in older homes. It is better to remove the old siding, fix the issues, and then build a better, stronger shell of new siding.
Improve Your Moisture Protection
Adding a layer of siding over an existing layer may increase your R-value, but it will also cause an interior moisture problem, which will eventually rot your walls from the inside out. With a complete tear off, a new moisture barrier can be put in place. Newer materials, such as wraps and foam, can be applied. This creates an air gap, which serves both as insulation and protection from condensation moisture, especially in colder climates.
A Complete Tear Off Is More Aesthetically Appealing
Recessed windows and doors aside, adding a second layer of siding to your home just doesn't look as crisp and clean as a single layer does. The new siding can appear misaligned because the old siding has likely settled. The old siding can eventually bulge if it becomes rotted, which in turn can cause the new siding to bulge or crack, requiring repairs down the line.
