Roof leaks in Asheville church

Upon expecting the inside of the church, it was apparent there were 2 separate leaks—one on the upper roof and one on the lower front roof. We had difficulty getting on the metal roof due to weather, so we had to do the inspection/work over 2 days when it was safe to get on the roof. The following is what we found and what we did.

 

How we are going to fix leaks on this metal roof

  1. 1
    Several areas water could come in

    Here are the areas we caulked that water could be penetrating the roof. The first noticeable place was the large crack running along the window sill and wall. This is a crack in a concrete wall running up the front wall of a church.

    Here are a few pictures of the caulk we added.

    Leak at the steeple of the church

    Once on the upper roof, it is evident that where the cross met, the roof was leaking. This is a close up view of a round pipe boot on a square metal.

    We will remove the old pipe boot and clean the area well to fix this. Then we will add a layer of ALDO roof coating, then a layer of a Kevlar style fabric, and then 2 more layers of ALDO. This will create a solid rubber coating around this area that is almost impervious to UV rays. The red circle represents the area we will coat in ALDO.

    Rusting metal panels that are compromised

    Along this side of the roof, the metal panels came up to be not wide enough towards the top of the roof, which means they started the metal panels crooked, or the top of the roof is a bit wider than the bottom. So they had to add a piece of metal to make up that distance. There are cracks and gaps between the metal panels that also need to be coated. I outlined this area in red.

    Rusting metal panels have gaps and cracks

    This site is very similar to the other side of the roof, and we are proposing to do the same thing and use ALDO to coat this section outlined in red to keep water from penetrating the roof. This is a view of metal roof panel that has a gap and pulling from the other panels. This is a rusted metal roof panel that is pulling away from the other panels.

Coating roof to repair leaks

  1. 1
    Repairing the steeple

    This was a bit of a challenge as when I took the old pipe boot they used to try and keep water out (bad idea) of the bottom of the cross. There was obviously a huge crack or opening for water to get in almost all the way around the the base of the cross.
      I used butyl tape to close up this opening this way the coating although thick wouldn’t run down in the crack.
    The coating we used has a fibrous base in it. This will keep it from cracking over the years.

    Large gaps in rusted gable metal

    This gable metal on both sides of the roof is more worn out than any of the other metal and should be replaced in the not too distant future. With that said there was large gaps between the transitions and also gaps in a section of metal they used to cover up a roofing error. So either the metal panels are slightly crooked or the top ridge on the left side of the church is out of square. I would say the panel’s are slightly crooked. 
    we used a roof coating to fix these areas. It is infused with fibrous material to keep it from cracking in the future

    Rusted gable metal with gaps

    This side actually had bigger gaps to fill and it was more challenging to get the 2nd layer of coating to stay in place. But we were able to continually work the coating back in place as gravity wanted to pull it down. After working if for a while it started to dry a bit and finally stayed in place. Here are a few pictures of where all we applied the coating.

    Here are a few pictures that I didn’t add so I figured I would add them here
