Stone Fireplace?

We have an A-Frame style home with a blue stone fireplace running outside & in. We've had a water leak with this fireplace since day 1. The stone extends 3' above the peak of the roof. On the back side of the outside section of the fireplace you can see white stains from water running towards the places where the fireplace joins with the roof. The water travels to the inside of the fireplace and where the sheet rock abuts with the fireplace, causing sheet rock damage. You can also see the water stains running down the inside rock. Attempts were made to solve this problem, including replacing the roof. We had several roofing firms seal the fireplace around the roof line and the top section that extends above the top roof line. We also have a large piece of slate covering the opening at the top. Our house is being vinyl sided and we have asked if a cap can attached at the top. The problem is since the stone is so hard, there doesn't seem to be a way to secure anything to the stone.

  1. umm so just drill and a-bolt into it
  2. Use mortar to seal the stone, they have a poly mortar sealer that works real at Lowes.
  3. We had the same problem, never could get the leak stopped until we removed the stone where it contacted the roof, made a concrete flat surface there instead. We then siliconed and flashed the concrete/roof joining and that solved the problem. We had a great roofer who did the whole job saving us the cost of a stone mason.
  4. When you have a fireplace you need to put a cricket were the chimney comes out the roof, that keeps water from running back down the gaps. Call a contractor that knows about chimneys. Good luck.
  5. have you look at a product by geocel ? 2310 it is a tripolymere its better then silicone stays flexible and dries clear i have many customers with leaking skylights, roof leaks , and other types of leaks use the product. its works well with any type of product and can be used in temperatures up to 40 below zero. it can be applied to a wet surface. you may consider investing in a gallon and it will not hurt your roof. its carried by bradco and abc roofing yards you can even get it through abc supplies catalog dept. it runs about$50.00 a gallon i even had a customer seal the brick on the front of his house with it because of leaks.
  6. Sure you can. If you want to attach something to the stone just drill with a masonry bit & use pretacs(TM) or anchors. Use roof patch cement with fiber(cost $10 per gal) or lap with cement(cost $10 per 50 lbs). If you use cement to lap it you will also need to use a sillier(urethane) after it dries. This will work if it is well attached to your house but if the chimney moves at all it will brake what ever you use. If this is the case go inside of the attic & attach a 2x6 to the stone where it meets the roof & screw the roof to the 2x6 then do the above steps.
