Sacramento Roofing: Article About Complex Roof Leaks
A roof system has many different aspects that go into its construction. From sheathing and resistive barriers to the shingles and flashing, there are dozens of places where a leak may show up. Sacramento roofing contractors are experts at finding, repairing and preventing any further leaking or problems that may show up. During the installation process, something as simple as a missed nail can cause a leak. Other complex procedures are even more prone to failure. While these leaks can involve a lot of work to fix and may require a professional contractor, it's wise to know how to spot them and the steps involved to repair them.
Probably the hardest place to waterproof is where soffit meets the roofing material. Any misstep during the installation of flashing and shingles in these areas usually leads to a leaky roof, especially in cold climates. Locales that are prone to snow and ice tend to experience a roof problem called ice dams. When ice dams occur in areas with soffit, major leaks can happen. This is because the ice dam prevents water from properly flowing off the roof. The water backs up behind the dam and slips under the shingles and flashing. Eventually, the water will make its way into the soffit.

Once it has reached this point, leaking into the rest of the home is inevitable. This kind of problem can be tough to fix, but there are several tips and tricks one may try in order to remedy the situation.
The first thing to check is the flashing. Deteriorated or damaged flashing is typically the main cause of leaks in the soffit. While installing new flashing can be a chore, it's also very doable for a homeowner. In this situation, remove the shingles and underlayment until the main roof sheathing can be seen. This sheathing is typically wafer board plywood.
Once the shingles and tarpaper have been removed, it's time to install the flashing. To do this, use a piece of ice and water barrier, found anywhere roofing tools are sold, and slide it in between the soffit and the plywood ensuring that it reaches all the way to the roof edge. Then, install step flashing as the new shingles are laid. This step flashing goes behind the fascia board where the gutter attaches. Finally, make sure the valley flashing overlaps the step flashing by at least two inches. This should solve any leaking from rain or ice dams.
