Siding FAQs, answered by experts

You can calculate the required square footage of siding you need by measuring the height and width of your home’s rectangular exterior walls. For the triangular-shaped gable walls, measure the height from the ground to the tallest gable point to make sure you have enough for good coverage. Once you have combined the totals for each wall, add another 10% to account for wasted materials. It’s also good to have extra siding on hand to tackle wood siding repair down the road.

You cannot install clapboard siding on a bare, unprepared surface. Clapboard siding requires a clean, sturdy base made from plywood or similar materials, sometimes called backerboard. Then, it needs an underlayment or sheathing, a moisture membrane to help protect the exterior wall.

Note that sometimes clapboard siding is caulked as it’s installed for additional protection. We don’t suggest this: Caulking the siding can trap moisture inside the clapboards and lead to moisture damage over time. The siding needs some space to “breathe,” especially in rainy weather.

Not always. The answer depends on your specific vinyl siding product. While some manufacturers advise against pressure washing, others recommend pressure washing as long as pressure is kept below a certain threshold.

There are a few options to choose from when it comes to shingle siding, including cedar shake, vinyl, and fiber cement. You can get these shingle siding materials in different colors, shapes, and sizes, giving you plenty of room to customize. You can also combine different siding materials and patterns with shingles for a more unique curb appeal.

Some homeowners use caulk on the edges of clapboard siding to help seal it. However, this method invites new problems. With so many gaps sealed, clapboard siding is often unable to drain properly and moisture from rain or other sources can build up inside. This can lead to rot and other issues over time. When repairing clapboards, it’s best to avoid caulking the final product. The exception is trim around windows and doors, which should be caulked to avoid moisture problems.
