HOW DO I SPOT POTENTIAL TROUBLE ON MY ROOF?
Re-Roofing When is it time?
When the shingles start to show signs of deterioration it is time to consider re-shingling your roof. Signs of problems are most likely in roofs that are twelve years or older.
- Loose or missing shingles – missing tabs due to wind damage or brittleness and excessive granules from the shingles in your eavestrough or coming out of the downpipe
- damaged flashing – pieces of metal or roll roofing wrapped around vent pipes, chimneys and adjoining walls to prevent water seepage and leakage
- buckling and curling – shingles that are bent up in the middle or turned up at the corners
- blistering and rotting – bubbles, caused by moisture in the shingle, appear on the surface of asphalt roofing
- discolouration or algae build up – all of our 30-50 yr shingles are algae resistant
Typically there will be sections of your roof that will deteriorate faster than others. This is dependent on a number of factors including:
- direct exposure to sunlight (southern & western slopes)
- areas that are subject to heavy water flow i.e. closed valleys, downpipes that are not extended to the trough and guide water flow directly onto the shingles
- over hanging trees and lower slope areas where water and ice can sit for long periods of time or roof decks that were not properly prepared with ice and water shield at the bottom 3 feet from the eaves
