An overview of the EIFS Termination at Parapet Specification
In this post we are going to talk about the EIFS Termination at Parapet Specification. I have been doing EIFS for a long time and when we are out on repairs it seems like this is one of those things that is almost never done correctly. The proper way to terminate a parapet is to apply Dryvit’s Aqua Flash over the entire top of the parapet and down both sides at least 2″. Read more EIFS Termination at Parapet Specification ›
An overview of the EIFS Grade Termination Specification
In this post we will be taking a look at the EIFS Grade Termination Specification. Before we get into the grade termination spec it is understood that the substrate already has be treated with an EIFS approved moisture barrier (see the post . for more details on applying the moisture barrier).

Terminating EIFS at the grade, brick ledge and the roof line.
Terminating EIFS is something we address frequently here at EIFS Repair. We are going to talk about terminating EIFS horizontally. When terminating the EIFS at the grade there should be about 8 inches from the foam to the ground. There are several reasons for this but mainly for insects and moisture. The first row of foam should sit in a weep track which is a plastic track with holes in it for moisture drainage.
Terminating EIFS at a soffit. I see a EIFS soffit wrapped right onto the existing wall all the time but when you think about it if a wall comes down and wraps under onto a soffit and a weep track is not installed at the end of the wall the moisture drainage system is being negated because it can not drain at the end of the face wall. In short the face wall and the soffit should be two separate applications with the face wall having a weep track installed and the soffit having an expansion with backer rod and caulk against the face wall weep track.
Terminating EIFS at the Brick Ledge. When terminating the EIFS at the brick ledge it is important to have the flashing installed before the EIFS is applied. You always want the flashing to drain out to the face of the brick. The weep track will still be used in the moisture drainage system. The flashing is not enough because the EIFS has to have a place for the moisure if trapped behind the system to get out and that is what the weep is for.
Terminating EIFS at the roof line. The roof line maybe the one issue of terminating EIFS I see screwed up the most. It is not possible to take EIFS right down to the shingles and think that a caulk joint between the EIFS and the shingle will keep water out. Common sense should tell even a novice that that is ridiculous but you would be surprised how often we see this. Standard procedure is to keep the EIFS up off the roof rake 2 inches and use a weep track. Also I can not stress enough how important it is to install a kick out flashing at the end of the roof flashing.
It is not a good idea to have EIFS to close to the ground for several reasons. First and foremost, you do not want water to get in behind it so obviously you would not want it right down to the ground. But how high up does it have to be and what do you do with that area that is not done in EIFS down there? That is the question your customer will ask and what the always want to hear is that it will look the same as the rest of the wall. But, more often than not, the 4″ or 8″ that is not done in EIFS down there is just left by the EIFS contractor and the owner paints it the same color and it all flakes off in no time and looks bad.
I would suggest to put a direct apply on the area before sticking the foam and take it up past the 8″ mark and Mesh and brown like normal and then when you run finish you could just run it all and it would all look the same and there would be no foam down there any longer so the water would not get in behind to cause any damage. This way the entire wall looks complete and the EIFS will not fail from water getting in behind the foam.
Seems like a no brainer but I see a lot of buildings with that 8″ gap at the bottom that does not have EIFS or even worse the EIFS with the foam all the way to the ground.
