There are several different signs that you need a new roof…..

• if there is a lot of cracking on the shingles it is a sign of deteriation
• if the shingles are buckling
• if the tips of the shingle are curling, this also causes a concern for winds getting under the shingles and tearing them off the roof.

We do not recommend more than one layer of shingles however by city codes you are allowed. It will depend on the condition of the existing roof. If the roof has one layer of shingles that are laying flat and the deck is in good condition, the existing shingles typically do not have to be removed. Check with local officials to make sure that building codes are being followed.

The difference between fibreglass and organic shingles is the type of mat that is used in the production of each shingle. Organic mats, which are used to make organic shingles, are composed primarily of cellulose fibres derived from selected recycled paper or converted wood chips. On the other hand, fibreglass mats which are used to make fibreglass shingles, are composed of glass filaments of various lengths and orientations, bonded together with inert binders. Both types of shingles are made with ashphalt. Fibreglass shingles have been found to outlast organic shingles in even the harshest climates.

Buckling is defined as ridges that form along the length of the shingle, with the ridge spacing usually coincidental with deck board joints. These ridges are caused by the shingle being distorted from the movement of the deck. Buckling can occur from any deck type, but is more common with board decks, and less common on plywood decks. Buckling can occur when a new roof is installed, even if the old roof did not show any buckles, when the roof is stripped, the deck may be exposed to moisture, causing dimensional changes in the supporting lumber. Therefor it is important to re sheet any areas where there is a potential for buckling.

Every spring it is recommended to check your roof for missing shingles caused by harsh winter winds. Every fall you should have your eavestrough and downpipes cleaned and cleared of any depris. years Every 5-7 it is recommended to do a maintenance check on your whole roof. All flashing areas, and areas where caulking has been applied should be checked for cracking.
