Maintenance for PVC Roofing

What You'll Need
Duct Tape
Cloth or Rag
Alcohol or Household Cleaner
Splice Cleaner
Rubber Gloves
Caulking or roof tape

PVC Roofing is a popular choice for roofing material among residential homeowners. For one, the PVC roofing has been proven to last for 30 years or more with regular and ongoing maintenance. Second, PVC roofing also supports cool roof technology which helps to keep the attic as cool as possible from the sun's rays. Last, but certainly not least, PVC roofing is an environmentally friendly choice. In order to get the most out of your PVC roofing material, you will need to properly maintain it over the course of the years. Here is how.

Step 1 - Get Your Ladder Out

Take your ladder out and lean it against your house. Have someone spot you down below as you climb up to the roof's surface. You never want to climb a ladder on your own without the necessary safety precautions.

Step 2 - Check the Roof

Visually inspect the roof. A PVC roof is sometimes prone to shrinking. When it shrinks, the seams come away from one another. This can promote deterioration of the integrity of the roof and therefore can cause leaks.

Step 3 - Mark the Shrinks

Using a piece of duct tape, mark the areas that you see shrinking. This will give you a map or a guide as you begin your maintenance steps for each of the locations that have shrunk over time. Duct tape should be used because it is easy to see over the dark roof.

Step 4 - Clean the Surface

Using a little alcohol or a household cleaning solution, clean the ares that you have marked. Never apply any type of maintenance patching or solution without first cleaning the surface. Wipe the surface dry with a rag or a cloth.

Step 5 - Apply Splice Cleaner

Put on a pair of rubber gloves to protect your skin's surface. Apply splice cleaner to the surface that you have just cleaned. You can purchase splice cleaner (also known as white gas) at any local home improvement center.

Step 6 - Apply Sealant

Now you will need to seal the areas that have shrunk. Take out a polyurethane sealant (also known as caulking) or roof tape. Apply either of these materials to the PVC roofing material. If you choose to use roof tape, you need to apply enough pressure over the surface you are maintaining. This will help to promote the proper amount of adhesion.

Step 7 - Tap any Loose Nails or Screws

Most roofs are rolled on or adhered with a few nails and screws. As they loosen and start to push up, the integrity of the roof is compromised and you should just tap them down lightly until they maintain contact with the roof's surface.


Do not walk on your roof if the temperature outside is less than 50 degrees. PVC roof material has been known to shatter and crack in colder temperatures. In order to maintain the integrity of the roof, you should only walk on it when the weather conditions are appropriate.
