Chase Top Repair

This chimney is brick veneer
pre- fab with standard galvanized sheet top. Most pre-fabs are wood or vinyl sided. You can see the rust that has taken hold.

This house is 15yrs old in lochmere.

Here we have removed the square cap and see the area to left of cap in top picture. The rust has started flaking off meaning there is a lot of rust there... You can also see the black blobs that were used to seal the nails they used to secure top. Most of them leakes as well. We pulled out 7 nail in all around the top. Plus 4 screws used to attach square cap.

This is what the metal looks like under the real rusty area. You can see the pitting that has occurred allowing water to drip down inside the chase are. In this house the water ran down a ceiling joist and stopped at wall causing stains and sheetrock damage.

Here we have installed new chase top made of stainless steel. Notice the cross breaks in metal to create a roof effect. This prevents most water from pooling on the cover. The cap was re screened and painted to look new. There are only 2 penetration on top of cover and both are double caulked with 50 yr silicon.

At this home we had 2 chimney with 2 fireplace vents in same structure. The chase tops were very rusting and rust was running down side of structure.. They wanted us to replace the tops before the house was to be repainted.

Here we see the finished product. the chase top was replaced with a black Color-Clad product that carries a 25yr warranty against rust. we also knocked the surface rust off the chimney tops and repainted they with a rustoleum black spray product.

This is other chimney structure on the same home with rusting as well..

here we have replaced and repainted the existing gas flue and chimney top.
this was done in oct 08 in north Raleigh location.
