There are few areas in your home that need to stand up to the test of time and the elements more than your roof. Roof replacement and repair jobs that either just patch the problem up, or don’t fix the problem at all, can lead to a lot of time and money wasted as well as a huge headache in the future.
These 10 major roofing mistakes show a lack of proper roofing knowledge and are a bad sign if you see a contractor making one of these mistakes.
1. No Leak Barriers
Though this may seem like common sense, there are some roofers who will either purposely not install or forget to install a leak barrier before they put the shingles on. This can end up being a huge problem with skylights since a leak could develop over time.
2. Improper Installation in Valleys
The last thing you want is for your roofing replacement and repair contractor to be putting nails in your roof’s valleys. As time goes by, that nail hole can end up giving water direct access to the underside of your roof, and straight into your attic. Most roofers will not make that mistake, but they may use an improper shingling method which can allow water to collect in the valley leading to major problems relatively quickly.
3. Neglecting Attic Ventilation
Making sure an attic is properly ventilated goes a long way in reducing the temperature in the attic and on your roof deck. Shingles can start to show signs of damage from extremely high temperatures, making them ineffective and warranting a replacement. Your contractor should have attic ventilation in mind if you are building a new home but it is also important in existing structures. An attic vent can be put in for a few hundred dollars and can save you a lot of money on your electric bills in the summer.
4. Not Installing a Cricket Behind a Chimney
The area behind a chimney where water would normally pool on a roof needs to be eliminated so that you don’t develop a leakage problem around the chimney. This is where a cricket comes in. All it does is help divert water away from the chimney to keep it flowing down to your gutters. For an experienced roofing repair and replacement expert like those of us at AJ Wells Roofing Contractors, these are simple to install and are almost mandatory to prevent leakage problems years from now.
5. Using the Wrong Shingles for Hips and Ridges
The hips and ridges on your roof are going to experience the most direct winds and the highest wind speeds. It is important that special shingles are used that will ensure that the shingles in these areas are kept in place during storms and that water properly flows off of both sides of them. Special shingles are made that are more durable and thicker which need to be installed as opposed to regular roof shingles.
6. Bad Starter Course
Your starter course at the edge of your roof needs to be properly installed in order for it to be effective. What this does is it creates a dual-layer of shingles right next to the edge in order to prevent any leakage. Your contractor should be staggering the shingles so that water doesn’t seep between them this low on the roof.
7. Putting Shingles on Shallow Sloping Roofs
Because a shingled roof is designed to help channel water away from the underlying structure, it is not completely waterproof. If the angle of the roof is too shallow, the water will not be able to flow fast enough to prevent seepage. A roofing repair and replacement professional should be able to tell fairly quickly if a shingled roof would work in your case or if you need something more solid such as a metal roof.
8. Not Installing a Drip Edge
A drip edge is extremely important in preventing water from getting into areas where it can rot wood, erode soil, or discolor your siding. Not installing a drip edge is a sure sign of a roofer who you do not want to use. It takes relatively little work to install, and serves a multitude of purposes, all of which will keep your roof functioning longer. Also, it helps protect other areas of your home.
9. Improper Flashing Installation
The flashing that goes against chimneys and other obstacles for water on your roof needs to be installed correctly to be effective. This usually involves making sure there is a substrata of something to seal the gap underneath, followed by step flashing on top, which is nailed to the deck of the roof.
10. Nailing Shingles the Wrong Way
It is important that nails are being driven in perpendicular to the shingles so that the fiberglass matting between the asphalt layers of the shingle does not tear or otherwise become compromised. Most roofing repair and replacement specialists take great care to put their nails in the right way, but some may go too quickly and get them in at an angle. Another problem that causes tearing is an over-pressurized nail gun which can do the same thing driving in nails at an angle does. Most roofers will double check their pressurization to make sure that they aren’t driving the nails in to forcefully.
