Now that we have staples out of the way, let’s talk about nails. When you attach a shingle to a roof deck, you can use 3-6 nails of various lengths. If a roofer in Portland tells you use 6 nails for your recover they are correct. You will obtain a higher wind warranty from the roofing shingle manufacturer if you do. Why else is it important?
In the Portland area, we get the occasional storm that produces 100 MPH winds and shingles all over east county blow off of roofs requiring roof repair or roof replacement. Roofing contractors that use 6 nails on every shingle they install sleep well through these storms because they are not worried about the number of panicked customers calling with warranty claims. If you live in the Columbia River Gorge, you need to check specifically into the manufacturers wind warranty as there are other things you will want to verify with your roofing consultant. How do I pick the right shingle?
There are many shingle manufacturers right here in the North West that manufacture shingles specific to our climate. I believe in shopping local so I want something that is from a local manufacturer. You will want to get as much information as you can from your roofing contractor about what shingles they recommend, and find out what level of certification your roofer has with the manufacturer. Ask them about upgraded warranties. Many certified roofers can offer longer warranties than other contractors because they have been factory certified to install a particular manufacturer’s shingles.
