The good news is that there are 4 useful ways to tell if the roof of your house has been installed correctly or incorrectly. Check the flashing. Check shingles to see if they are properly nailed or protruding. One of the easiest ways to check the quality of the roof installation is to look at how the tiles have been aligned.
Check if the cutouts of the three-tab shingles are vertical and if the butt joints are in the same horizontal plane. On the tour, of course, make sure it's clean and collected. Check the valleys and make sure they are straight, check the metal edge to make sure it is properly installed and not just hammered. If they do a good job and the obvious little details, I'm sure the rest of the work is also good.
Your inspector will look for signs of subsidence, which is a cause for concern when installing a new roof. Beyond that, the fascia and ceiling tiles must also be inspected, which, while not as substantial as the main structure of the roof itself, can cause significant damage if not installed correctly. The inspector will also check the chimney for damage, including wear. Does your roof just look worn out? Do you see moss or dark streaks everywhere (both can be a sign of dampness, which is damaging the roof)? Does the whole roof look like it's sunk? Do you see inconsistent colors in the tiles? This could mean that the granules have come off for one reason or another.
Granules are the shingles first line of defense against bad weather, once the granules disappear, the roof is susceptible to further damage and leakage. Asphalt shingles are the most commonly used materials to replace the roof. While they are widely used by several contractors, some do not install shingles properly. Whatever the reason, however justified it may be, the fact is that lower roof replacements occur.
A professional, certified roof inspector will know how to perform the inspection work and will review each section of your roof to identify any problems that may require immediate attention. These are the things that specialists check in the roof inspection after installation to inform you of any amendments your roof may need. Also, seek the services of qualified roof inspectors to determine the condition and value of your roof from time to time. That way, you won't have to worry about poorly installed roofing systems that might require replacements or repairs a few days after the actual installation.
If you suspect damage to the roof, taking a look under the roof after looking at its exterior is never a bad idea. In rainy western Washington, it's crucial to identify leaks early, as well as make sure the roof drains properly to prevent roof moss and water damage later on. If your roof has dark veins or if some shingles feel damp after it rains, this means that some parts of the roof are retaining moisture and may need to be redone. A professional roofer can come to inspect the damage and determine if a spot repair will tie you up, but can discuss what is the best option for replacing the roof.
Also, if you are thinking of selling your home soon, replacing your roof can be a good decision. In a poorly installed roof situation, you will see tiles of different colors, missing drip edges, or ventilation grilles that have been reused rather than replaced. From here, the roof inspector should also be able to detect any problems with the felt or membrane used. If you have a complex roof with many faces that makes it difficult to inspect the condition of the shingles or shingles, the inside of your roof is also the safest way to check for obvious problems with those shingles without using special tools.
While there is no code violation associated with reusing old flashings, quality roofing contractors know that the nails used to install the new roof will not always go through the old holes in the reused flashing. .
