Cost of hiring a professional
Roofers charge about $ 150 to $ 300 per roof area on top of the cost of materials, which typically brings the total price to install a new roof over your existing roof to about $ 5,400 to $ 10,900, according to home services company HomeAdvisor . Removing the old roof or repairing damage can add to these costs.
In some cases, homeowner insurance can cover some or all of these expenses. Opting for cheaper materials can also lower the bill. If you install an energy efficient roof that meets certain criteria, you may receive a tax credit.
2. Mold removal
Everyone got rid of a little bit of mold at some point, and even the U.S. Environmental Protection Agency gives the green light to DIY mold removal for areas under 10 square feet. However, once the mold infestation is widespread, it may be necessary to open walls, lift carpets, or remove fixings to completely remove it and thoroughly clean and dry the room. A DIY approach in this case means risking:
- Mold exposure: Contact with mold can cause asthmatic reactions, sore throats, skin reactions, allergic reactions, eye and nose irritation, coughing, wheezing, shortness of breath and other lung problems. This is especially important if you do not have access to the correct protective equipment. During the COVID-19 pandemic, N95 respirators, which provide protection against mold and other particles, were largely unavailable for public purchase.
- Strong chemical exposure: Chemical cleaners, commonly used to kill mold, are also harmful to the lungs, eyes, nasal passages, throats, and skin.
- To make the problem worse: Improper removal or sealing can cause mold spores to get into the air. When spores get into HVAC systems, mold blows all over the house. Do-it-yourselfers can also miss mold lurking in unexpected places like crawl spaces or floors, which can cause further damage.
- Incomplete cleanup: If you don’t clean up properly after work, it can leave traces of mold that simply grow back.
