Like other home improvement projects, replacing your roof can be costly. You might want to consider an alternative option of re-roofing. The roof over design refers to placing new shingles directly over the old ones. According to San Antonio roofers, the potential problems caused by the roof over placement outweigh the benefits of costs. Roof over decreases the life of new shingles due to moisture and heat buildup.
Here are some important tips from leading roofing companies in San Antonio that will help you take the right decision while replacing the roof.
- Measure roof size accurately
If you want to get an exact estimate for replacing the roof, you need the exact roof size. Hire a San Antonio roofing expert to measure the roof size. You need to understand roof measurements. For example, a square refers to the amount of material required to cover 100 square feet surface. If the roofing expert tells you roof has 20 squares, it means you need to cover 2000 square feet surface.
- Repairing the supporting structure of the roof
When you are considering replacing the roof, you need to take into account repair costs for underlying wood. Placing new shingles over damaged wood is not advisable as it reduces the life of roofing materials. Ask the roofing San Antonio expert to take a look at the underlying wood pieces and their condition and see what needs to be replaced.
- Check the ventilation
Roof venting is an essential factor that should not be overlooked. The roof has to bear high and low temperatures along with moisture. Proper venting of the roof ensures modulation of the temperatures and prevents excessive build-up of moisture during the wet season. A properly vented roof can withstand the vagaries of the climate in a better way and also last longer.
- Install protective coverings
The new shingles should never be fixed directly to the underlying wood. Ask the roofing contractor to install protective coverings made of felt that provides adequate protection to your home from water and ice.
- Wind Resistance
Make sure the roof design is wind resistant especially if you are living in a region that experiences high winds. If you are unaware of the wind zone location of your building, contact County or town building code enforcement officer who can tell you wind classification of the shingle proposed for your building. Not all metal shingles are wind resistant, but most wind-resistant shingles are made of metal.
- Look for a licensed contractor
Always hire a licensed roofing contractor who can provide a material and labor warranty. The contractor you choose should follow the regional and local regulations for roofing and also get the necessary permit before commencing the work. The roofing contractor should have a good experience doing such roof replacements.
Follow these tips above and reduce the maintenance charges and have a long-lasting roof.
