There's usually a
standard sequencing you follow when tackling a home remodeling project. In short, you work from the inside out, taking care of the internal parts of the structure first as well as the protective elements (roof). We didn't quite follow the sequence, so please learn from our mistake.

Fix your roof first. Wait, let me restate. Take care of all water intrusion issues first, ESPECIALLY if you're remodeling your house in the middle of rainy season. Our inspection didn't uncover any roof issues aside from the fact that we would have to do some general maintenance to keep it in working condition until it would need to be replaced in about 3 years.
Less than two weeks after we closed, the
Bay Area was rained out a one-day storm that toppled a 40+ year record. It rained nonstop for 12 hours, hard. When the rain subsided we went to go check on the house and to our dismay we found this in the first floor bedroom, bubbled up paint.

Water was making its way into the house and seeping into the walls. We also found water on the sill of the front window in the master bedroom spilling over onto the floor. Two words, not good. We contacted a few roofers to inspect the damage and most agreed that the roof wasn't the issue, but rather the flashing. The problem was the roof intersection of the front to the second floor. There was no
step flashing. Flashing basically prevents water from coming into the structure at joins and intersections wit the roof. The previous owners had obviously known about this problem and tried to solve it by slathering caulk into the roofing intersection. Over time, their quick and cheap fix became weathered, and cracked allowing the water back into the house.

In the interim, we decided to go again with the previous owner's temporary patch and slapped some more caulk on until we decided on a contractor and course of action. And it seemed to hold up well with the light showers that followed the big storm. We were definitely fortunate that the rain laid off for as long as it did. Our contractor was to install flashing with the new siding which would take care of the source of the water intrusion. But because they started with the side and back of the house first, they didn't get to install the flashing before another big storm put all work on hold.

O hai, wet wallAaaaaaand water came back into the house, seeped into the walls and made their way down to the floors, the brand, new hardwood floors.. the ones that still have yet to be sanded.. the ones they JUST finished putting in.

Aaaaaaand then the master bedroom windows started leaking again, overflowing actually, letting water in and onto the floors, the brand, new hardwood floors.. the ones that still have yet to be sanded.. the ones they JUST finished putting in.


Aaaaaaand then we discovered a new leak in the kitchen, actually at the kitchen intersection with the main house. We suspected it was, again, a flashing issue, letting water into the house, dripping into the kitchen, seeping into the walls and making their way down to the floors, the brand, new hardwood floors.. the ones that still have yet to be sanded.. the ones they JUST finished putting in.



We put the rest of the floors on hold until the flashing and siding job was completed and the source of the kitchen leak identified and fixed. In the meantime, we put out fans to help dry out the walls and floors which seemed to do the trick. Fortunately, the floors weren't damaged. But we certainly learned our lesson.
Making sure your house is watertight is the most responsible way to protect your investment. Take care of this first above all else especially before you start cosmetic projects.
