Then look no further, we have them here. We have researched this list of Portland roofers for you. They all meet up with our standards of job knowledge and overall workmanship.As your roof gets older in age, you will more than likely need to have it repaired or replaced. When a home owner calls a Portland roofing contractor for a repair or possibly replacement, they need to be ready to make a decision. The home owner needs to decide if a repair is going to be good or if they need to look into a total replacement. If they decide on having the roofer do a total replacement then a tear off should be done.A tear off is where the company removes all the old material 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 repaired or replaced then you should listen up. Nailing new material into bad wood is like installing your new roof on a sponge.Once the structure is in good shape then the felt paper can be installed. Felt paper is not for sealing, it’s main purpose is to keep the plywood sheeting from drying out the oils in the material. Then the next step is to choose what type of roofing they want on their house and what color. Once they have decided on the material then the Portland roofing contractors can move forward with the job.Roof Tear Off – Portland Roofing Contractors.A tear off will usually take a couple of days depending on the size of the building. Remember weather can be a factor, it may be more important to make the building water tight then doing a complete clean up of the yard. So give the roofers some time. Doing a tear off is the best way to do a complete inspection of the structures durability. Such as the plywood sheeting and any fascia boards. It is not advised to put the new roofing on bad lumber. If you replace the sheeting then there is a better chance the roofing will not blow off in a wind storm. Attaching to bad sheeting is like nailing into a loaf of bread.30 Year Composition – Portland Roofing Contractors.30 year composition is the choice of most Portland home owners. This product is a very good for the Portland area. With proper maintenance it will last a couple decades or more. It is made up of Laminate composition material and will stand up to high winds.Presidential Roofing – Portland Roofing Contractors.Presidential is the system that a lot of Portland “H.O.A.’s” may make you use if you are not wanting to use cedar. (This is a heavy duty, high wind, long lasting roofing material that is designed to look like cedar shake, kinda.) It is made up of thick laminated composition roofing material. Think this is not a Do It Yourself roofing system. Hire a professional roofer on this for sure.3 Tab – Portland Roofing Contractors.3-tab was used a lot back in the 70’s and into the 80’s here in the Portland area, they are not a good shingle for the area. One common mistake made with 3-tab. It’s not to be installed on roof of less than a 5/12 pitch. This roofing is usually made up of asphalt material, it is very thin and does not do well in wind. There is really no reason to use this type of roofing as it is just dollars cheaper then a 30 year composition.Metal Interlocking Roofs – Portland Roofing Contractors.Metal lock seam is a great choice, but one of the most expensive systems. The interlocking systems that are available in Portland is by far the better system when you are talking about a metal roof. (Metal can be very loud in a rain storm.) Metal systems can last a life time with proper maintenance.Ceramic Tile Roofs – Portland Roofing Contractors.Ceramic tile, This type of roofing has a very long life. Here in Portland there is really no reason not to use ceramic tile. It does not have any problems with rot or mold. The cons with tile roofing is the weight of the tiles and the cost. If your home was not engineered to have tile, you should consult with a Portland framing specialist before installing tile to make sure the structure can handle the weight. There is also a lighter metal version of tile roofing. (You do not want to walk on the tile roof as they can be very fragile.)Cedar Shake Roofs – Portland Roofing Contractors.Cedar shake, In Portland a cedar shake roof only looks good for a couple of years. Then it takes almost a yearly maintenance program to keep it looking good. In Portland a cedar roof will last you maybe 20 years with good maintenance. If you have a cedar shake roof and are thinking about getting up there your self, think twice. It is usually wet, so the shakes will be very slippery. Old roofs will start to curl and the shakes will break when you walk on them. A cedar shake roof is a O.K. choice for a roof here in Portland, but I would go with a Presidential roof.Commercial Roofing – Portland Roofing Contractors.Commercial roofing (flat roofs) here in Portland is a little tricky because we get so much rain. There are really only 4 different methods of roofing a flat roof. The older buildings may have hot tar applied to the roof structure. (This is the old way of doing flat roofs). Or maybe they have a torch down roof. (torch down has a short life time and extreme fire danger when installing).The new way to roof a flat area is with P.V.C. or T.P.O. roofing (Thermoplastic Polyolefin). These two methods come in rolls and are strips of membrane roofing that are adhered to the surface and welded together at the seams with heat. (heat gun or iron). A good Portland roofing contractor that does quality commercial roofing is hard to find. As it takes a lot of patience to install some of these types of roofing systems. But we have done it, view our list of commercial Portland roofing contractors above.Flat Roof Repair – Portland Roofing Contractors.Flat roofing is one of the hardest repairs a roofer can do. Even well qualified roofers have trouble sometimes chasing down where the leak can be coming from. One of the biggest problems with the flat roof is the water can just sit and puddle on the roof. This gives the water a chance to seep down through the cracks that may have developed in the seams. Or if the roof is a older hot tar type roof the leak could be coming from anywhere.Applying tar to the roof is only a band-aid, it may just move the leak to a different area. After applying tar to a roof it will need maintenance every year. The first couple months it may work. Then the tar will dry out and crack in the summer months. Many roofers will take a torch and reheat the tar instead of applying more. If you are searching through the internet looking for Portland roofing contractors that do flat roof repair, we got them.Residential Roof Repair.One of the worst feelings you can get as a home owner is finding out your roof is leaking. Our crews of Portland roofing contractors that we have listed can help. Leaks can come from something as small as a crack in the rubber of a pipe jack or bad flashing’s around a skylight. More advanced roof repairs would be something like a leak in a valley or shingles missing off the roof.If you are a Portland Do It Yourself type of person: Here are a couple troublesome areas to check. A tube of sealer may get you through the winter. (We advise you NOT going up on your roof. but if you do, be careful and try not to walk up the valleys, you can put a hole it it.)Have a roofer access your roof then check the following areas.The rubber seals around the pipe jacks.Cracked air vents.Exposed nail heads.Missing shingles.Holes in the valley.Flashing around the chimney or side wall.Portland Roof Leak Repair.One of the main reasons for a leaky roof here in Portland is the use of staples instead of roofing nails during the installation. As the roof ages and flexes with the weather. The head of the staple can rub the back of the upper shingle. This can cause the nail head to work up through the top shingle. A roofing nail has a flatter head then a staple ,of about .35 of and inch. A staple is about .02 of an inch. (The head of the staple is smaller and sharper then the head of the roofing nail.) It is also harder for the wind to pull up the roofing when using the nails. Ask your roofer to use roofing nails not staples.Another reason for a leak, is improper installed valley, If it is not installed correctly it will leak. A less experienced roofer may not cut the tabs when installing the valley (This is a must). An open metal valley is a better way to go, rather than a closed valley. it will cost a little more, but so very much worth it.[services include: residential roofing contractors, commercial roofing contractors, roof repair contractors, tear off contractors, roof replacement contractors, roof recovers, flat roof repair, torch down, laminate, presidential roofing contractors, metal roofs, interlocking metal, 3 tab roofing, T.P.O. roofers, P.V.C. roofers , roll roofing, cedar shake contractors, plywood sheeting, roof maintenance, roof cleaning contractors, composition roofers, tile roofing contractors , asphalt roofers, roof inspection, air vents and commercial roof repair contractors.Brands Offered: Malarkey, CertinTeed, Gaf, Atlas, IKO, Owens Corning, Pabco, Tamco.]Simply the top roofers that preform repairs in Portland.Portland Roofing Contractors & Roofers.Oregon Roofing Contractors Network.
