My small garden shed (that I have my eye on for my second coop, but don't tell DH) is leaking and we can't figure out where it is coming in. The roof is a peaked roof and the leak is near the edge about 6 inches up, between the 2nd and 3rd rafter. We bought a gallon of Stop leak for roofs last weekend and DH coated the roof from the peak to the edge about 4 feet wide, (messy, smelly job and he coated it real well) then we put drip edge along the entire end but it rained last night and it is still leaking. If we don't get it fixed soon the shed is going to be ruined. The siding on that corner is already rotten out and will have to be replaced which we can do, but we are not able to climb up and replace the whole roof. And we can't afford to hire someone to fix it. Any ideas how to figure out where its coming in?
