If you know what to look for, you can resolve many issues before putting your house on the market. Additionally, if you do a major roof repair or replacement, it can be reflected in the final price of the home.
1. Clean all moss and debris off the roof
Stubborn algae, moss, and fungi can grow on virtually any type of roof, even roofs designed to prevent it.
Use a broom with a mild cleaning solution or even a leaf blower to remove mold growth from the roof. Remove the growth of algae and fungus by mixing equal parts bleach and water in a spray bottle and applying it to the affected areas.
Only use a pressure washer if it’s absolutely necessary, as you may cause serious damage to the shingles and roof.

2. Repair damaged shingles
Severe storms, high winds, and hail can all damage shingles on your roof.
Look for patchiness on your roof, as the difference in color may point to missing shingles.
You can replace a few missing or damaged shingles yourself with just a few basic tools...
Use a pry bar or similar device to slide underneath the nails that connect the damaged shingle to the one beneath it.
Lift until all the nails are removed, and pull out the damaged shingle.
Replace with a new shingle.
Secure the new shingle using four nails.
However, if you notice large amounts of damaged shingles, we recommend calling a roof repair contractor. A home inspector will notice shoddy repairs performed by a homeowner, so invest the time and money to have a qualified professional fix large sections of your roof.

3. Clean out the gutters
Clogged gutters can cause a multitude of problems for future homeowners.
4. Divert all downspouts
Water draining too close to the foundation can cause some serious moisture and structural issues.
This provides some added length and ensures water discharges well beyond the base of the house.
5. Remove tree branches
Trim away any tree branches or shrubs that are in contact with the roof.
6. Inspect soffit and fascia
Inspect your soffit and fascia for any holes, cracks, or rotted sections.
If you discover mildew or mold growing on your soffit and fascia, use a brush or broom and a cleaning solution of bleach and water to gently remove it.

7. Check chimneys and skylights
Closely look for cracks along chimneys and skylights.
These areas are prone to roof leaks and are one of the first places on the roof the inspector will look at.
Look for the following before the inspector goes up on your roof:
- Clear off any debris and attempt to determine if the skylight is fitted correctly.
- Check for cracks around the chimney flashing and skylight window.
- Seal any minor cracks with a clear roofing sealant.
- If you notice cracked flashing, remove it and replace the section with a new piece.
8. Get your paperwork together
Create a file with the necessary documentation on all the maintenance and repairs you’ve done on your roof.
If you filed an insurance claim for a roof repair or replacement, keep those handy too. Home inspectors will want to know if your roof has been repaired, how frequently, and, if you've filed an insurance claim, what the state of your home insurance is.
If there are any tips on this list that you're not comfortable with fixing or inspecting yourself, it's best to hire a professional roofing contractor before the home inspection.
