The short version
- Temporary repairs stop water for a while
- Permanent repairs restore the roof
- Both are often needed after a storm
- Keep the temporary work as light as will do
Temporary repair
A tarp, a membrane, a patch or a few replaced shingles can keep a roof watertight for a time. The purpose is to protect the building until a permanent repair can happen.
It is usually quick and inexpensive compared with the permanent work.
Permanent repair
A permanent repair replaces damaged materials correctly, seals the details and restores the roof to its intended performance. It takes more time and materials and depends on weather and supply.
It is what you pay for in the end.
Why you often need both
After a storm, you may need to cover the roof immediately, then wait for insurance, materials or dry weather. The temporary measure covers that gap.
Plan the permanent repair as soon as you can.
Avoiding double spending
Ask what the temporary measure is, how long it should last and whether any part of it becomes part of the permanent repair. A reasonable contractor keeps temporary work simple.
Get the plan in writing, if you can.
