There are leaks and there are leaks. Some leaks are small and contained, while others are big and out of control. Usually the bigger ones are obvious, and you can get to work solving the problem before it develops into a lot more damage. The challenge with small leaks is, they are often not discovered until they have dome a lot of damage. But in every case, it is always worth doing an inspection as soon as possible. And in a lot of cases, you can get a totally free inspection from a licensed, bonded and insured roofing contractor.
I assume your question is about the roofing materials, so I will answer the question accordingly.
Roofing in the Pacific Northwest presents a unique challenge that almost no other region in the country faces. A lot of rain. Clearly, it rains in places like Florida, too, but it tends to rain, then stop raining so a roof can get a break and a chance to dry out. It’s also much warmer, and the sun can bake a roof dry quickly in that heat and sunshine.
I assume from your question you are planning or installing or replacing an existing roof on your home. There are a number of considerations, not just question to ask your roofer, but how to approach the project from beginning to end.
My house in Bellevue gets a moss on the roof because it is shaded. How can I prevent damage and avoid replacing my roof?
A lot depends on what your roof is made of, but almost any roof surface in Puget Sound will eventually collect moss, or something like moss, especially if it is always in the shade. Direct sunlight is a great way to keep moss from reaching critical mass on your roof, and there are certainly many things you can do to limit the effect of moss, algae and other things from growing on your roof.
Many people, when they first discover that their roof must be "replaced" think it must be the whole top part of their house. In fact, it is usually only the few layers on the surface. The roofing materials (shakes, synthetic materials, etc.) and the waterproof underlayer are usually all that needs to be replaced.
Here's more on the subject, gleaned from the Internet:
My old house in Bothell, the roof is leaking. Do I need to replace the whole roof, or just do a partial re-roofing?
There are several critical elements of a house, but it has to be said about the Puget Sound that a roof might be the most urgent part of a house to fix when there is a problem with it. Once a roof begins to let water into the house, you can’t always tell how much damage is finally going to be done. You might have great insurance coverage, but every insurance policy on Earth has conditions under which the payout amount may be reduced. If, for example, it was decided negligence was involved, or the roof was not adequately replaced in time, you the homeowner may be partially at fault.
We all pride ourselves in living in a unique house. In the Old Country, rows and rows of houses were built to be mostly identical. Only time made them look a little different, but here in the Pacific Northwest, we want our little ‘castle’ to look unique. We paint it the colors we want, put whatever roof we like on it, and even when it was first built, it looked different for all the other houses on the block. The American Dream, they tell me. So, when it comes to replacing that roof, what options do we have?
What is the best material to use on a re-roofing project on a typical Buchan style home in Kirkland / Issaquah area?
“How long is a piece of string?” is how my father would have answered the question. There are so many roofing materials to choose from these days – and more coming onto the market every year – that you now have both form and function options you did not have a few short years ago.
