roof leak question


Do you think the only problem is the way the roof and flashing were installed? What are the chances there is a problem with the chimney itself as well? I ask because we are going tomorrow to purchase a new woodburning fireplace insert. Planning on having it installed with a full stainless steel liner and new chimney cap/top plate. We had a chimney sweep out a few months ago who said the chimney itself seemed fine. We were not aware of the leak at the time. If the roof needs to be repaired we would likel have it done before the insert/liner instal but they have a clearance sale on the inserts this weekend so we would save a lot of money by getting it now. Would hate to buy a new insert and then find out my chimney was bunk and in need of replacing? No time to get a roofer out before to inspect it. Anything I can look for myself? Thanks again for your help.

Cut that stucco type exterior back to the wooden structure and flash the frakin thing in aluminum or copper. This looks like a repair so it was probably done like this by someone who either didnt want to pay to do it right or by a roofer that doesn't know what he's doing.

roof leak question


I do not see any voids that stand out from the photos at the top terminations of the flashings. I would concentrate more on checking out the top portion of the chimney, similar to what Tinner mentioned, where the shingles are lifted up at the side edge of that one shingle.

Also, how far back does that membrane flashing go?

And remember what I said before, that EPDM rubber is not a water-tight seal when nails from the shingles penetrate it.

Without cracking or tearing that lifted shingle, can you look under there to see how far back it goes. Irregardless, that entire flashing job is done incorrectly and needs to be redone properly. That is most likely the source of your leak.

roof leak question


Had someone out to look at the roof this afternoon. Said the chimney looks fine but that we may want to consider putting a layer of sealer on it. He says the problem is definately the flashing. States their plan would be to remove the rubber flashing and several feet of shingles around each side of the chimney. Cut out and remove any rotted plywood sheating as needed. Put down a ice/snow guard membrane over the plywood. Install metal step flashing with counter flashing and either reinstall existing shingles or matching ones. Cost of $800. What do you think? Sound like this is the correct way to do it and will fix it? Quote sounds reasonable I think?

On a side note what kind of sealer would you suggest for the chimney?

Thanks for all the help.

Price is very fair.

Make sure that they wrap the Grace Ice and Water Shield not only on the decking, but around all 4 sides of the chimney behind where4 the sheet matal flashings will be in contact.

I would also recommend installing a saddle/cricket behind the chimney to divert water to either side as it`s over 30" in width(closer to 40,I would recomend a small valley be attached to the metal cricket,on each side ,and all joints be sealed,I would want it to be redone in copper so all seams and joints can be soldered,cost with a cricket /saddle would be around $1600.00 for that size chimney,and I would definitely want all new shingles used at the chimney perimeter

you want to waterproof the perimeter up the walls,like this;

the apron,and steps;

counterflash;

and be sure to use a good sealant like Geocell mortar seal to put the finishing touches,and seal the raggle/reglet like this;
nothing quite like a clean copper chimney flashing with soldered joints;
