The average Asphalt Roof only lasts 13-15 years. This is due to the use of low quality materials and improper installation. Additionally some Roofs are not covered under manufacturer warranty because of improper installation. There are however things you can do to make your roof last 25-30 years or double the average roof lifespan.
Make sure your contractor does the following:
Use of 30-40 Year high quality Shingles.
Use of Synthetic waterproof underlay on entire roof surface.
Installing 6 nails in each shingle instead of 4 (Manufacturers Requirement).
Use of Ice Shield on first 44” from Eaves and In Valley’s for protection from ice and snow.
Proper Shingle placement in valleys to enhance water evacuation.
Absolutely NO Exposed nails left or tarred- Full replacement of shingles.
Offers 5 year Installation warranty on all work.
All of these steps help add time to your roofs lifespan. Replacing your roof is a big investment and you need to trust that the proper materials and installation practices are being used & followed to ensure a long lifespan for your roof and warranty coverage.
