But, you may wonder, what they will check for?
To answer your question, we’ll tell you below what our experts look for when they check out any roof.
What a roofer look for when inspecting a roof?
1. Missing or broken shingles:
Over time, asphalt shingles age. They suffer a normal process of wear and tear after resisting years of exposition to the elements. Therefore, they get weak and breakable, and strong winds can tear them off.
Besides, have in mind the following:
Does your roof have large areas without shingles? The reason may be poor installation. Badly installed shingles are likely to fail ahead of schedule.
Poor roofing work can cause shingles to deteriorate early, and manufacturers know that.
Moreover, a bad installation can void your shingles’ warranty.
If you have an old roof or your shingles were incorrectly installed, you’ll need a roof replacement to prevent more costly repairs down the road.
2. Moss, mildew, or mold
Moss, mildew and mold are responsible for those horrible dark patches in your roof. But, besides affecting your home curb appeal, these elements damage the shingles and underlayment.
Thus, during the roof inspection, our team checks carefully for signs of these menaces that hold moisture on your roof surface, leading to leaks and rotten roof deck.
3. Ventilation problems
Insufficient attic ventilation is one of the worst enemies of your roof. When an attic does not have proper ventilation, hot air generates condensation that can rot the roof deck. Likewise, the heat makes shingles brittle and curling over time.
Vents and mechanical ventilation systems allow the hot air out and cool and dry air in. So, during a roof inspection, our experts check how they are working.
If you have ventilation issues in your roof, our roofing team will propose options to improve air flowing.
4. Ripples, blisters, or buckles
Ripples, blisters, buckles, are signs of many roof problems. Among these issues are:
- Very old shingles
- poor ventilation
- inappropriate installation
- Damaged sheathing
- Multiple layers of shingles
- Wet underlayment
As shingles age through time, some physical changes appear on them. When these changes are evident from a roof inspection done on the ground, you may need a roof replacement.
5. Multiple layers of shingles
A roof with more than one layer of shingles won’t have proper ventilation. Thus, it will retain heat and moisture under the shingles.
That’s why many manufacturers require their shingles to be installed on clean roof decks. You can verify this on your asphalt shingles’ warranty details.
6. No drip edge
Drip edge is a type of flashing at the edges of your roof that protect the wooden fascia from water runoff (at the eaves) or wind-driven rain (at the rakes).
You may have a rotting fascia due to filtering water if your roof doesn’t have a drip edge or it was installed inappropriately. roof cleaning in dorset
