The good news is that there are 4 useful ways to know if the roof of your house has been installed correctly or incorrectly: check the front cover. Check that the shingles are correctly nailed or that they stick out. One of the easiest ways to check the quality of the roof installation is to observe how the shingles 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 tidy. Check the valleys and make sure they are straight, check the metal edge to make sure it is properly installed and not just nailed. If they do a good job and the small details obvious, I'm sure the rest of the work is good too. Your inspector will look for signs of subsidence, which is definitely a cause for concern in a new roof installation.
Beyond that, there is also the fascia and the ceiling to be inspected, which, while not as substantial as the main roof structure itself, can cause significant damage if not installed properly. Your inspector will also look at the chimney for damage, including wear and tear. Does your roof look simply worn out? Do you see moss or dark stripes everywhere (both can be a sign of moisture, which damages the roof)? Does it look like your entire roof is sunk? Do you see inconsistent colors on the shingles? This could mean that the granules have come off for one reason or another. Granules are the roof tile's first line of defense against bad weather.
Once the granules disappear, the roof is susceptible to further damage and leaks. The subfloor plays an important role in your roofing system, as it is a felt-like material that is installed under shingles and above the roof cover. A qualified and professional roofing contractor makes sure to maintain the beauty and integrity of a home with a satisfactory roof installation. You can even ask your friends and neighbors who they chose to replace your roof and follow up with those contractors to make sure they have the above requirements.
This is why you should always hire a certified roofer to have your roof replaced, but also why, even when you get a certified roofer to take care of it, you should have your roof inspected afterwards. By providing a free quote to prospective customers, you not only attract people to call them, but you also demonstrate that they understand that homeowners need to repair or replace their roof. This is because most insurance companies will never insure any old roof before they are presented with an inspection report to demonstrate the structural integrity and aesthetic value of the roofs in question. One of the most likely places to find evidence of a hasty or inferior roof replacement is inside.
In rainy western Washington, it's critical to identify leaks early, as well as ensure that the roof drains properly to prevent future moss and water damage. Plus, if you're thinking of selling your house soon, replacing your roof may be a good decision. If the roof has dark stripes or if some shingles feel damp after the rain, this means that some parts of the roof are retaining moisture and may need to be rebuilt. As much as things like leaks are an inconvenience, it's the structural aspect of having a new roof installed that makes it so crucial to perform a roof inspection.
A tile that isn't nailed properly exposes nails to stains and eventually the newly replaced roof starts to leak. That way, you won't have to worry about poorly installed roofing systems that could require replacements or repairs a few days after the actual installation. Finding structural problems in the roof is not as easy as looking at the outer parts of the roof that could have problems. When it comes to installing the material, this generally boils down to ensuring that things like shingles are fixed in place properly, that the felt on the roof doesn't break during installation, and that the masking is properly shaped on the roof.
If the roof is poorly installed, you'll see differently colored shingles, missing drip edges, or ventilation grilles that have been reused instead of being replaced. . .
