It is surprisingly common to find a shingle finish on house walls. It can look stylish but, once the damage starts to appear from wear and tear, you’ll quickly find there are numerous problems to deal with.

Because shingles are laid overlapping, in a similar way to your roof structure, it is surprisingly easy for moisture and insects to find their way through the shingles and into your walls, causing an array of issues.

This can be a result of rising damp or a small crack in any one shingle. The fact that many houses have wooden shingles also means you have the issue of maintenance. Failing to maintain them properly will leave the shingles open to damp ingestion, causing them to swell and start to rot.

In short, if you have shingles you’re going to need to visually inspect them regularly, this will help to ensure you catch any issues early.

Unsurprisingly, many homeowners with shingle walls consider the different types of cladding for houses instead. The question then becomes one of how easy is cladding to fit, especially over your existing shingles.

The Short Answer To Can I Put Siding Over Shingles


You will find that it is done in some cases, but these are generally rare.

There are several reasons why putting cladding over shingles is not a good idea:

Rot & Mold

If your shingles have rot or mold then installing siding over the top will effectively trap the moisture and give it a warm environment in which to flourish. In short, the growth and spread of the rot will multiply and make the fastenings for your new siding week.

In addition, if you remove some of your old shingles you’re likely to find there is more mold, rot, and other types of wall deterioration you think there may be.

To protect your home properly and help it last for years, you need to remove all traces of this mold and rot, before you add your new cladding.

Weather Issues

If you choose to put siding over shingles then you won’t be able to add a moisture protection layer. This is a sheet that usually goes against the walls and prevents moisture from getting into your home. At the same time, it allows your walls to breath and lets moisture out.

Not only will this improve your insulation by reducing any drafts, but it will also help to prevent damp and rot issues in the future.

Simply adding cladding to your shingles means you don’t have this option, which could cause a problem in the near future.

Thickens The Walls

A shingle finish is not even, this means you need to add rigid foam to absorb these irregularities and provide a flat surface for the cladding to adhere to.

This could increase the insulation of your home, making it warmer in the winter. However, it will also increase the depths of your walls, making the doors and windows appear more recessed. Most people would say this is not an attractive look, although you’ll have to decide this issue for yourself.

It doesn’t take a lot of extra effort to remove the shingles first, and it really is worth it.
