The leading line of work they perform in Portland is roof repair and new roof installs. When a home owner calls a roofer, they needs to be ready to make a decision about the roof. At this time the home owners needs to decide if a repair is going to be good or if they need to look into a total roof replacement. If they decide on having the roofer replace the roof. The next process is to choose what type of roofing they want on there house and what color. Once they have decided on the roofing selections the roofers can move forward with the job. Roof replacement includes doing a roof tear off. A roof tear off is where the company removes all the old roofing materials from the home and possibly the need to replace the sheeting of the plywood on the roof structure. If a roofer says your plywood needs replaced, you should listen up. Nailing new roofing into bad wood is like installing your new roof on a sponge. Once the structure is in good shape the felt paper can be installed. Felt paper is not for sealing the roof, it’s main purpose is to keep the plywood sheeting from drying out the oils in the roofing. The felt paper is usually fastened to the roof with staples, this is ok. Many roofers will use a power stapler to fasten the shingles to the roof, this is not a good practice.One of the main reasons for a leaky roof in Portland is the use of staples during the shingle installation. As the roof ages and flexes with the weather, snow load and wind, the top of the staple rubs the back of the upper shingle and eventually works its way up through the shingle. A roofing nail has a flat head of about 3/8 of and inch, while a staple is about 1/32 of an inch. Ask your roofer to use roofing nails no staples. The 2nd biggest reason for a leaky roof is a closed valley. If a closed valley is not installed correctly it will most definitely leak. a inexperienced roofer will not cut the tabs in the valley. A open metal valley is a better way to go, it will cost a little more, but so very much worth it. Especially if your home is under any trees. the fir needles will not stick to the metal valley as much as a closed valley.30 year laminate roofing is the choice of most home owners. Presidential roofing is the system that a lot of “home owner associations” will make you use if you are not wanting to use cedar. Cedar is a nice look, but if you need a repair on a shake roof, the walking on the roof during the repair could cause more damage to the roofing. A good roofer will not walk on a bad cedar roof as it can open up a can of worms. 3 tab roofing was used a lot back in the 70’s and into the 80’s they are not a good shingle for the area. One common mistake made with 3-tab is it is not to be installed on roof of less then a 5/12 pitch. Also if not maintained moss will grow in the keys of the roofing and then the water will back up and find away through the roofing system causing a leak. Metal lock seam roofing is a great choice but one of the most expensive systems. One note on Metal Roofing it can be very noisy in a rain storm.The largest city in Oregon in our system is Portland.
