Older homes may have outdated roofing installations that pose risks. Underneath the roof, you may discover structural or electrical hazards. Roofs on older homes could also have sagging, materials that are too heavy, and compromised and aging decking. When replacing a roof, you need to know these basics to avoid mishaps and ensure the best new roof installation possible.
Full Tear-Off of the Overlays
An older home requires a full tear-off of the overlays. Many homeowners may layer new shingles on top of old ones to save money on roof maintenance. However, it’s best to remove all the roofing materials and start fresh. Then the roofer can find any issues immediately and correct them.
Consider the Structural Load Capacity
The structural load capacity determines what materials you can use for the new roof. Many older homes aren’t built to support heavier roofing materials. A professional can inspect the property and determine if reinforcement is necessary.
They’ll calculate the structural load capacity and recommend roofing materials according to your budget. For some older homes, they may recommend more lightweight roofing materials.
Inspect the Decking
The age of your older home can determine whether the decking is too outdated. Many older houses have spaced roof boards instead of solid plywood. Under these circumstances, the roof may not meet current building code requirements. A roofing professional can inspect the decking and determine if you should replace it.
Upgrade the Ventilation
Older homes may have premature shingle failure, leading to ice dams and improper ventilation. A roofer can create a more balanced system to upgrade roof ventilation. For example, they will install soffit intake vents and exhaust vents to maintain airflow.
Additionally, they may install baffles to avoid obstructions. They may also add drip edge vents if there isn’t an overhang. Solar-powered attic fans can improve roofing ventilation, too.
Complete Flashing and Chimney Repairs
Roofers will inspect the flashing, especially around valleys and chimneys. Fresh flashing can reduce leak risks and protect the roof and property.
Leave the Hard Stuff to the Pros
A professional roofer will manage and obtain any permits you need for the new roof. They will also comply with all local building codes. They understand how to prepare the site and prevent damage to your property, automobiles, and other possessions around your home. The roofers can assess risks in your attic and follow measures to prevent damage and financial losses.
When renovating an older house, the roof is generally one of the first challenges. When replacing a roof on an older home, you should know the basics, so there aren’t any surprises. You must address the full tear-off, the structural load capacity, and proper ventilation. If you need a professional roofer to replace your roof, contact us at Heyn Brothers Roofing in Rochester, MN.
