Porches are often attached to the house.

Underside of porch roof. Go for a board and batten approach by covering the seams with 1 by 3 inch fir cedar or redwood trim. Subtract inch from this measurement to account for the inch gap you want to leave around the perimeter of the ceiling to allow the wood to expand. There is no drywall attic space or cathedral ceiling covering the underside of the roof. A wet roof can cause mold to grow on the underside of the porch ceiling.

Porch roofs can also develop ice dam problems like the rest of the house s roof. The metal seamed ceiling is a perfect choice for your shallow sloped roof while the cedar clay slate asphalt and concrete will be ideal materials for your steep sloped ceiling. This means that simply by looking up you can often assess damage such as insect infestation or water stains caused by leaks. Unlike your main roof which is largely out of sight out of mind your porch roof is directly overhead.

Be sure to stagger the butt seam joints or anywhere the end of one soffit board plank meets another. Deck waterproofing expands your outdoor living space by making the area under your porch or deck usable for family and friends. Measure the depth of the porch front to back at the end where you will start installing the beadboard. Condensation can cause leaks and unattractive stains on porch ceilings.

Cut the soffit board planks so the ends are aligned with the center of the patio trusses. Problems with porch roofs can cause intrusion of water into the interior of the house. Using a miter saw cut a piece of beadboard to this measurement. Now you ll have space for a sunroom or three season room in areas not otherwise suitable.

Nail them to the trusses using the large gauge finish nail gun. The vaulted ceiling will be ideal in the hot areas and small porches as it is installed directly under the roof pitch the open ceiling will blend perfectly with the rustic styled porch as it reveals the supporting rafters of your ceiling. These are right angled notches which help the rafter s underside to sit flat on the top plate of the wall. The underside of an aging porch roof often exhibits cracking wood or dark stains revealing that it needs some attention.

If it is reachable with a mop a simple bleach solution should work just fine. For example asphalt and cedar shingles are generally not considered a good choice for shallow sloped roofs a metal seamed roof would be a better choice. Transform that unusable space into an entertainment area complete with finished ceilings comfortable lighting fans and more. But if you have a steep sloped roof you have more options.

Building a porch roof is a complicated process that requires a complex approach. You can use plywood on a porch ceiling but in such a way that no one will notice it. Begin at the patio to exterior wall transition and work your way down toward the fascia.
