The short version
- Older roofs often have multiple layers and past patches
- Chimneys and valleys are frequent trouble spots
- Historic materials need specialist care
- Inspection before renovation avoids surprises
Layers and patches
Older homes may have had several roof replacements, and sometimes new roofing over old. Extra layers add weight and hide deck problems. Patches from past leaks may mask ongoing issues.
An inspector looks for signs of layers and repairs.
Details that age
Chimneys, valleys, dormers and porch roofs tie into the main roof with flashings that have often been repaired repeatedly. Original sealants and metals have often long since failed. Older homes often have more complicated rooflines.
Detail inspection is crucial.
Historic materials
Slate, clay tile, cedar shake and metal roofs on historic homes need specialist inspection and repair. Walking on them can cause damage, so drones and careful access are used.
Preservation guidelines may apply.
Before renovating
If you plan to renovate, add on or sell an older home, inspect the roof first. Findings affect budgets and sequencing. Fix roof problems before interior work to avoid damage.
A report is a planning tool.
General information, not engineering, legal, insurance or safety advice. Roofs, policies and local requirements vary, and every roof should be judged on its own condition.
