Joining A Flat Roof To A Pitched Roof

While that s the easiest route it s certainly not your only option.

Joining a flat roof to a pitched roof.

I wondered what is the best way to do this. First we should establish the pitch of both roof planes. Depending on the climate your flat roof will only last between 15 and 30 years if well maintained. We ll start with the knowledge that the main roof has an 8 12 pitch.

After this roofing cement is applied around the complete area and then the missing tiles are replaced. Alternative is a roll of wide dpc. The roof needs to be tied in by lifting up some of the original tiles on the existing roof and then allowing the flat roof to run slightly underneath. 12 to 18 inches wide.

When assessing the pitch of a flat roof always get an accurate level onto the roof and carefully study the degree of fall to build up a mental picture of potential snags before you get them this way plans can be made in advance of problems. Joining a flatty onto a pitched involves chopping all the existing roof stuff that exists below the level of the wall plate. Slip a new pitched roof membrane under the existing lift the existing gently and get up as far as you can. It is largely cosmetic in so far as the a framing is concerned in any case.

Joining these two roofs poses two main challenges. The other is to get the fascias to line up. Most homeowners choose to convert a flat roof to a pitched one using a simple trussed roof with two angled planes. This is stiff enough to push and wiggle under the existing felt if yoy are carefully you will manage it most times.

Joining different flat roofs. I have used the join roofs tool but then how is it best to add the fascia and guttering to connect to what will be the new modified roof. This latest project was in early december in lambeth ontario for a residential home that had an existing sloped or shingled roof that needed to tie into a ne. A pitched roof is more expensive.

One is getting the two differently pitched planes to meet at the hip or valley rafter. Flat roofs also don t last as long. This video will demonstrate how to integrate a cure it grp roof with a pitched roof. You then build this junction with ply layboards that extend up the roof far enough in order to sufficiently weather.

However flat roofs require much more aggressive and consistent maintenance than a pitched roof. Flashing and more roofing compound are used to weatherproof the joint. Additional valleys angles and gables can be built into converted roofs as well but adding these elements may affect your project.
