When patching stops being worth it

Most roofs give you two or three years of warning. The trouble is that the warnings are easy to explain away one at a time.

Step 1 of 6

What best describes your home?

Different buildings need different crews, so this is the first thing a roofer asks.

Nothing is charged and nothing is booked.

Daylight or damp in the attic

The attic tells the truth earlier than the ceiling does. Staining on the underside of the deck predates any stain you will see downstairs by a long way.

Sagging along a line

Straight lines going wavy means something underneath has softened. That is no longer a roofing question with a cheap answer.

The age on the paperwork

Age alone is not a reason to replace. Age plus any one of the symptoms above usually is.

Granules in the gutter

The granules are the sunscreen. Losing them in volume means the asphalt beneath is being cooked directly, and from that point the roof ages in years rather than decades.

Repeated repairs in different places

When the leaks stop clustering and start appearing anywhere, you are not fixing a fault any more. You are paying for a replacement in instalments, at a worse rate.

Shingles that curl, cup or go brittle

Look along the roof from the ground at a low angle rather than straight on. Edges that lift, corners that curl upward and a surface that no longer lies flat all mean the material has lost its flexibility. Brittle shingles crack when walked on, which is why contractors stop wanting to walk them.

In short

If two or more of these apply, get somebody to look at it and give you a remaining-life number in years. That single number turns the decision from a worry into arithmetic.

Related questions

Can I just put a new roof over the old one?

Codes in most places allow two layers. That does not make it wise. You lose the chance to see the deck, and the next roofer has twice as much to remove.

I rent. Can I use this?

You can submit it, but the owner has to authorise any work, so the useful move is to get the landlord to make the request or to give you permission in writing first. Contractors will not start work for a tenant.

Should I repair or replace?

Rough rule: if the covering has more than about five years left and the damage is confined to one area, repair. If it is at the end of its life or you are patching the third leak in two years, you are paying instalments on a replacement.
