This step by step diy project is about insulated cat house plans plans. This is PART 2 of the cat house project, where I show you how to build the roof for the project. This project is ideal if you have several cats that like to hang out outdoors. This basic insulated shelter will provide them a place to get rest. Take a look over the rest of my woodworking plans, if you want to get more building inspiration.
When buying the lumber, you should select the planks with great care, making sure they are straight and without any visible flaws (cracks, knots, twists, decay). Investing in cedar or other weather resistant lumber is a good idea, as it will pay off on the long run. Use a spirit level to plumb and align the components, before inserting the galvanized screws, otherwise the project won’t have a symmetrical look. If you have all the materials and tools required for the project, you could get the job done in about a day. See all my Premium Plans HERE.

Building an insulated cat house roof
Fit the polystyrene insulation sheets into the wall frames, as shown in the image. Cut the sheets with a utility knife and fit them to the front wall frame.
Fit the polystyrene insulation sheets to the back wall, as well. Make sure you take accurate measurements so the sheets fit into place properly.
Fit the insulation sheets to the side walls, in the same manner described above.
Build the interior walls from 1/4″ plywood. Remember that you also need to cut out the door opening for the front wall.
Cut the sheets at the right dimensions and secure them to the frames using 1 1/4″ screws.
Fit the 1/4″ plywood sheets under the roof as well, and lock them into place with 1 1/4″ screws.
Fit the insulation boards to the rood, as shown in the diagram, for a neat result.
Afterwards, you need to attach the 3/4″ plywood sheets to the roof of the cat house. Center the sheets to the roof, making sure there is a 2″ overhang on the front, as well as on the back face.
Cover the roof with tar paper and staple it into place tightly. Afterwards, you should install asphalt shingles to the roof of the cat house.
The cat house has a nice appearance seen from all angles. In order to get a professional result, I recommend you to fill the holes and the dents with wood putty and to let it dry out for several days. Smooth the surface with 120-220 grit sandpaper and apply a few coats of paint to enhance the look of the project and to protect the components from decay.
This is a simple project you should be able to build in a few days without much effort. Make sure you check out PART 1 of the cat house project, so you learn how to build the base and the frame of the cat house. Take a look over the rest of the woodworking project I feature on the site, for even more building inspiration.
