2 Reasons DIY Roof Installation Isn't A Good Idea
If your roof is in poor condition or even failing, you may choose to install a new roof on your home yourself. Although it could save you money on expenses at the moment, you could face a few major problems and expenses in the future. Some of these mistakes could be costly for you and your home. Here are two reasons DIY roofing installation isn't a good idea.
You Could Miss or Don't Detect Weak Spots
Roofs can develop problems over the years that make them structurally and mechanically unsafe, including weak spots. Weak spots, such as holes and rotting wood, can make your roof unsafe to walk on. If you can't locate all of the fragile spots on your roof, you may accidentally step on one or damage your roof even further.
A roofer can physically and visually detect weak or fragile spots on your roof, including dips and holes. The condition of your existing shingles can also indicate problems in your roof. Shingles that cup, curl, or even buckle may allow water, fungus, and heat to penetrate and decay the wood substrate beneath them. If a roofer detects rot in your roof deck or substrate, they'll repair the structure first before they move forward with the installation.
In addition to not noticing or finding structural problems in your roof, you may inadvertently place the wrong felt underlayment on your roof during the installation.
You Could Use the Wrong Felt Underlayment
Although felt is the most recognized and used underlayment used on residential roofs today, you must use the right type of felt to keep your roof safe from moisture and other problems. If your underlayment is too thin or light, it may not cover or protect your roof deck and home properly from rain and other hazards.
Felt underlayment comes in two weights or thicknesses: 15 pounds and 30 pounds. Fifteen pound felt underlayment is reliable but may not work well on your roof, especially if you live in a wet location. Thirty-pound felt underlayment is heavier and thicker than 15-pound underlayment. The heavy and thick material may last longer during bad weather exposure.
These are only a few DIY mistakes you may make with your roof installation. You can avoid the mistakes and keep your roof sound by allowing a roofing contractor to do the installation for you.
